What the experts say about colloidal silver and other silver-based antimicrobials...
[While the FDA uses their legal prerogative to assert that
colloidal silver has not been found safe or effective for use as
a natural infection-fighting agent, it has indeed nevertheless
widely been used as such since the early 1900's.
"Silver, in the form of a metal or as dissolved ions, fights
microorganisms by interfering with processes such as how they
breathe and reproduce. Tests show that silver ions kill
microorganisms ranging from harmful strains of e. coli that cause
food-borne diseases to the staphylococcus bacteria responsible
for serious infections.
"Applying colloidal silver to human subjects has been done in a large number of cases with astonishingly successful results...it has the advantage of being rapidly fatal to parasites without toxic action on its host. It is quite stable. It protects rabbits from ten times the lethal dose of tetanus or diphtheria toxin."-- The Use of Colloids in Health and Disease (1919), by Alfred Searle
"Colloidal silver is an inexpensive healing agent and disinfectant that has a myriad of applications. It is a clear golden liquid composed of 99.9-percent pure silver particles approximately 0.001 to 0.01 microns in diameter that are suspended in pure water. Colloidal silver can be mixed with either tap or distilled water and applied topically, taken by mouth, or administered intravenously."-- Prescription For Nutritional Healing by Phyllis A Balch CNC and James F Balch MD, pg 66
"Trace amounts of silver are in the bodies of all humans and animals. We normally take in between 70 and 88 micrograms of silver a day, half of that amount from our diet. Humans have evolved with efficient methods of dealing with that intake, however. Over 99 percent is readily excreted from the body.
Is silver harmful to humans? Unlike other metals such as lead and mercury, silver is not toxic to humans and is not known to cause cancer, reproductive or neurological damage, or other chronic adverse effects."-- Dartmouth University Toxic Metals Research Program
"Scientists have discovered that the body's most important fluids are colloidal in nature: suspended ultra-fine particles. Blood, for example, carries nutrition and oxygen to the body cells.
This led to studies with colloidal silver (electrical silver atoms). An electro-colloidal process, which is known to be the best method, is used for manufacturing the colloidal silver.
Colloidal silver appears to be a powerful, natural antibiotic and preventative against infections. Acting as a catalyst, it reportedly disables the enzyme that one-celled bacteria, viruses and fungi need for their oxygen metabolism.
They suffocate without corresponding harm occurring to human enzymes or parts of the human body chemistry. The result is the destruction of disease-causing organisms in the body and in the food."-- Nanotechnology in Medicine and Antibacterial Effect of Silver Nanoparticles, Department of Medicine, Institute of Medical Sciences, Banaras Hindu University, Varanasi, India, published in the Digest Journal of Nanomaterials and Biostructures Vol. 3, No.3, September 2008, p. 115-122
"Silver is highly toxic to most microbial cells and can be used as an antimicrobial agent. Silver-containing compounds, such as silver sulfadiazine, which has broad antimicrobial as well as antifungal activity, and silver nitrate, are used in medicine as topical agents. Colloidal silver is a suspension of extremely small silver particles and was used in medicine until the 1940s as both a topical and an internal antiseptic. Colloidal silver was also known as argentum colloidale, argentum crede and collargolum."-- PDR For Nutritional Supplements by Sheldon Saul Hendle and David Rorvik, pg 110
"Like werewolves and vampires, bacteria have a weakness:
“Silver’s microbe-killing properties aren’t news—in fact, people have known about them for centuries, says Dr. David Barillo, a trauma surgeon and the editor of a recent silver-themed supplement of the journal Burns. Alexander the Great stored and drank water in silver vessels when going on campaigns in 335 BC, he says, and 19th century frontier-storming Americans dropped silver coins into their water barrels to suppress algae growth.
During the space race, America and the Soviet Union both developed silver-based water purification techniques (NASA’s was “basically a silver wire sticking in the middle of a pipe that they were passing electricity through,” Barillo says). And new applications keep popping up: Barillo himself pioneered the use of silver-infused dressings to treat wounded soldiers in Afghanistan. ‘We’ve really run the gamut—we’ve gone from 300 BC to present day, and we’re still using it for the same stuff,’ he says.
No one knows exactly how small amounts of silver are able to kill huge swaths of microbes. According to Barillo, it’s probably a combination of attacks on the microbe’s enzymes, cell wall, and DNA, along with the buildup of silver free radicals, which are studded with unpaired electrons that gum up cellular systems. These microbe-mutilating strategies are so effective that they obscure our ability to study them, because we have nothing to compare them to. ‘It’s difficult to make something silver-resistant, even in the lab where you’re doing it intentionally,’ Barillo says.
But unlike equal-opportunity killers like endosulfan, silver knocks out the monsters and leaves the good guys alone. In low concentrations, it’s virtually harmless to humans. ‘It’s not a carcinogen, it’s not a mutagen, it’s not an allergen,’ Barillo says. ‘It seems to have no purpose in human physiology—it’s not a metal that we need to have in our bodies like copper or magnesium. But it doesn’t seem to do anything bad either.’”-- PBS, Nova Next, March 24, 2015
“Silver is beautiful — and a killer. The shiny white metal is a natural antibiotic. That means it kills bacteria. People have recognized this benefit since ancient times. Wealthy Romans ate using knives, forks and spoons made of silver. They understood that silver helped keep spoiled food from making them sick. In fact, historians think that is how we came to call eating utensils ‘silverware.’
Today, eating off silver is more about wealth than health. Still, silver continues to play a role in medicine. Doctors use silver-coated bandages to kill germs that might infect burns and other wounds. Silver also is sometimes used to coat medical devices, such as breathing tubes. This can reduce the likelihood that patients on ventilators (to help them breathe) will develop pneumonia from exposure to germs.”-- SocietyforScience.org, Nanosilver: Naughty or Nice?, August 2015
"Silver - both in liquid solution and as an airborne-aerosol - has been known since 1887 to be extremely toxic to anthrax spores. And it is widely reported in the medical literature on silver that various forms of silver, often at surprisingly low concentrations, routinely kills germs that are known to be antibiotic-resistant."-- International Anti-Aging Bulletin, April 1999, by James South, MA
"Colloidal silver just might be the next germ-fighting wonder drug. And not just for the serious threats making headlines: It's also effective against bacterial infections like strep throat, viruses like the flu, and fungal infections like Candida. No matter how much a germ mutates, it can't change enough to escape the damaging effects of colloidal silver. And in the process, the silver doesn't harm human tissue or kill off the good bacteria in the intestine the way antibiotics and other medications do."-- Dr. Jonathan Wright, MD
"Thanks to eye-opening research, silver is re-emerging as a wonder of modern medicine. An antibiotic kills perhaps a half-dozen different disease organisms, but silver kills some 650. Resistant strains fail to develop. Moreover, silver is virtually non-toxic."-- Science Digest, "Our Mightiest Germ Fighter" by Jim Powell, March 1978
"Colloidal silver has a long history in medicine as a natural antibiotic. It is very effective in killing bacteria, viruses, fungi, parasites and the cancer microbe. No serious side effects from overdosing have been reported."-- The Natural Way to Heal by Walter Last, pg 161
"Topically, it can be used to fight fungal infections of the skin or nails and to promote the healing of burns, wounds, cuts, rashes, and sunburn. It can be used on toothaches and mouth sores, as eye drops, and as a gargle to fight tooth decay and bad breath. It can also be used as sterilizer and can even be sprayed on air-conditioning filters and air ducts and vents to prevent germs from growing."-- Prescription For Nutritional Healing by Phyllis A Balch CNC and James F Balch MD, pg 66
"Pierce Instruments in Stowe, Vermont, markets Silvelon, a nylon-Silver fabric used to make odor-proof socks and shoe-liners, antiseptic kitchen sponges, wound and burn healing aids, and topical applications to speed healing of cuts, canker sores, warts, and acne releasing colloidal silver on site. Argentum Research has Silverlon."-- Anti-Aging Manual by Joseph B Marion, pg 12
"All of the organisms that we tested were sensitive to the electrically generated silver ion, including some that were resistant to all known antibiotics...In no case were any undesirable side effects of the silver treatment apparent."-- Dr. Robert O. Becker, M.D., Syracuse Medical University
"In the United States, colloidal silver is not approved for medical use. Companies that sell colloidal silver or the equipment to make it are forbidden by the FDA to tell their customers about colloidal silver's healing properties.
Interestingly, this has not stopped major pharmaceutical companies from producing other silver products that are approved for medical purposes. These products include silver gels, for cuts, burns and wounds (silver sulfadiazine cream, a compound, is extensively used); silver coated bandages, widely and successfully used in hospital burn units; and various silver compounds, for other purposes.
The existence of these products makes it difficult for government agencies to deny the health benefits of silver any longer."-- Nenah Sylver, PhD, The Rife Handbook – Chapter 3 excerpt, "Colloidal Silver"
"Another benefit to using silver is that it does not appear to create the same amount of resistance in bacteria as traditional antibiotics. Ian Chopra, Professor of Microbiology at the University of Leeds, reported in a 2007 article in the Journal of Antimicrobial Chemotherapy that there are fewer than twenty published reports of silver resistance in bacteria...Professor Chopra went on to indicate that 'current evidence suggests the clinical threat [due to silver resistance] is low' because of the 'multifaceted mode of action of the silver ion.'"-- S.M. Foran, Therapeutic Properties of Silver: an Historical and Technical Review
"Silver compounds have been used as medicine since the late 1800's and have been used as a treatment against infections by hundreds of thousands of individuals in the United States. Silver is a natural mineral in the same class as zinc, chromium, cobalt, copper, iron, magnesium, molybdenum, vanadium and zinc which are important for health maintenance. Humans naturally ingest from 22 to 300 mcg of silver per day from natural sources in food and water (1,2). Levels of silver vary in foods with the highest reported levels being in immune boosting mushrooms with up to 5mg/ kg of silver. There is evidence that silver is a natural critical component of our immune system and that low tissue levels associated with a dietary deficiency may result in a relatively weakened immune system, making one more prone to infection. The modern versions of colloidal silver (oligodynamic silver) are shown to have little or no toxicity."-- Dr. Kent Holtorf, Holtorf Medical Group, "Safety and Efficacy of Intravenous Oligodynamic Silver"
"To treat ringworm, use a sterile pad and apply colloidal silver to the affected area. Hands and feet can also be soaked in this solution, a natural antibiotic that destroys some 650 different microorganisms."-- Prescription For Nutritional Healing by Phyllis A Balch CNC and James F Balch MD, pg 388
"Silver's germ-fighting ability will soon get a workout in new uses. The metal kills disease-carrying microbes without the harmful side effects of chlorine, or other sanitizing chemicals. Silver will one day be laced into socks, dish towels, toothbrushes. Even home appliances, heating and air systems will use it. Industrial uses too... treating water and cleaning food processing gear"-- Kiplinger Letter for Business, May 4, 2001 issue
"Colloidal silver. Dose: Internally-60 to 120 drops three to four times daily. Externally, applied to a wound or burn-two to three times daily."-- Herbal Medicine Healing Cancer by Donald R Yance Jr, pg 314
"Colloidal silver is commercially available with a common solution strength of five silver atoms per million molecules of water, or 5 ppm, but it may be up to 50 ppm in very concentrated remedies. However, the size of the colloids may be more important than the strength in parts per million."-- The Natural Way to Heal by Walter Last, pg 162
"Taken internally, colloidal silver can be used to fight infection. It has been shown to be effective against more that 650 disease-causing organisms, including Escherichia coli (E. coli) bacteria and the fungus Candida albicans."-- Prescription For Nutritional Healing by Phyllis A Balch CNC and James F Balch MD, pg 66
"I know of no microbe that is not killed by silver in laboratory experiments in six minutes."-- Dr. Henry Crooks, M.D. (1921)
"Silver's ability to aid the immune system has been well documented for more than 100 years. For example, in 1909, the Journal of the American Medical Association reported that electrically generated silver ions increased white blood cell production. As we noted earlier in our overview of the human immune system, white blood cells are critical factors in human immunity, aiding the body in the destruction of cancer cells, viruses, bacteria, and other invaders. What's more, while white blood cells are the defenders of the human body, red blood cells carry life-giving oxygen to all tissues and organs. So silver apparently aids in both immune defense and in the support of life itself, by boosting both our body's red and white blood cells counts.
In 1939, researchers Hill and Pillsbury made similar findings, demonstrating an increase in white blood cells after silver usage [see: Hill, WR, D Pillsbury, Argyria: The Pharmacology of Silver, The Williams & Wilkins Company, Baltimore, 1939; p. 48.] And over fifty years later, researchers Remes and Williams found that silver ions appear to 'prime' white blood cells to go on the offense against a variety of biological insults [see Remes, A, Williams, DF, Neutrophil Polarization and Immunoelectrophoresis Assays in the Study of Complement Activation by Biomaterials, Biomaterials, Aug 1991; 12(6):607-13.] Furthermore, in 1919 Dr. H. Bechold, writing in his groundbreaking book of the era, Colloids in Biology and Medicine, cited evidence that silver ions increased both red and white blood cell counts.
And in their study Argyria - The Pharmacology of Silver (Williams & Wilkins, 1939), researchers W. Hill & D. Pillsbury reported that 16 rabbits were injected with silver of arsphenamine at intervals from three to seven days. (The silver content of the drug was 14.5%.) A majority of the rabbits showed a gradual increase in oxygen-carrying hemoglobin and red blood cells during the experiment. In more recent studies conducted in the 1970's, such as Treatment of Orthopedic Infections with Electrically Generated Silver Ions by Dr. Robert O. Becker, M.D., it is reported that silver ions give a healthy boost to human blood cell production. This may be related to the fact that silver is a "transitional element" giving it the ability to form complex ions. This attribute gives silver the potential to interact on a cellular level in the same way as other complex ions such as vitamin B-12, chlorophyll, and heme (iron), a component of red blood cells.
And in the 1980's researchers Berger, Marino and Spadaro confirmed that electrically generated silver ions boost human blood cell production. These findings lead to the obvious conclusion that while low white blood cell counts open the door to serious immune system risks, and low red blood cells lead to oxygen starvation of the body's tissues and organs, electrically generated silver ions may help successfully counter these risks by stimulating both white and red blood cell production."-- The Ultimate Colloidal Silver Manual, Barwick, Steve, Life & Health Research Group, LLC; www.UltimateColloidalSilverManual.com
"Dr. Marchial-Vega has had considerable clinical experience with a colloidal silver preparation that contains between 20 and 25 parts of silver per million parts of water. This preparation has proven effective in patients with HIV in quickly resolving pneumonias due to pneumocystis, streptococcal, staphylococcal, klebsiella and fungal infections. In the hospital, the therapy is administered by a special nebulizer as well as orally."-- Physicians Guide To Natural Health Products That Work by James Howenstine MD, pg 262
"Silver belongs to the family of metals that also includes copper and gold (both of which can also have numerous health benefits when they're used properly). One of the primary concerns people tend to have about using these metals is the risk that they'll accumulate in the body and lead to heavy metal toxicity. But if you have plenty of antioxidants in your diet, such as selenium, vitamin E, and amino acids like N-acetyl cysteine, you're safe from any harmful effects from this family of metals. Germs, however, are not."-- Dr. Jonathan Wright, MD
""Pure Silver is entirely non-irritant. In tests at very high concentrations, it has been shown repeatedly that the rapidly exerted disinfectant action is of considerable therapeutic value."-- Colloidal Preparations of Silver in Pharmacy, British Medical Journal, February 1923
"Sinus symptoms... You can also use 1 or 2 drops of colloidal silver or liquid pine bark extract in each nostril once or twice a day... Eye or ear problems, including cataracts, glaucoma, redness, blurred vision, poor eyesight, ringing in the ears, earaches, soreness or swelling of the ears, eardrum damage, hardness of hearing, and (in rare cases) loss of hearing: Use 1 drop of colloidal silver topically (directly in the eye or ear) 3 times a day."-- The pH Miracle: Balance Your Diet, Reclaim Your Health by Robert O. Young, PhD, pg 178.
"What we have done was rediscover the fact that silver killed bacteria, a fact which had actually been known for centuries...All of the organisms we tested were sensitive to the electrically generated silver ion, including some that were resistant to all known antibiotics...In no case were any undesirable side effects of the silver treatment apparent."-- The Body Electric, Dr. Robert O. Becker, M.D.
"Today, many antibiotics are losing the battle with germs. Fortunately, the best germ killer, which was discovered over 2,000 years ago, is finally getting the proper attention from medical science - natural silver. I sincerely recommend that everyone have electrically generated colloidal silver in their home as an antiseptic, antibacterial and antifungal agent."-- Dr. Joseph Weissman, M.D. board certified immunologist and Assistant Clinical Professor at the University of California Medical School
"The only natural substance I know of that is effective against these microbes is colloidal silver. I tested that myself when I was with the CIA, and found it effective against both anthrax and the bubonic plague pathogen."-- Bacteriological Warfare - A Major Threat by Larry Wayne Harris
"In contrast to medical antibiotics that can be used only against specific microbes, colloidal silver has a wide range of effectiveness, eliminating bacteria as well as viruses and fungi. Unlike medical antibiotics, colloidal silver is not known to cause undesirable side effects. Colloidal zinc can be especially effective against viruses. The colloids of copper and gold, on the other hand, are strong anti-inflammatory agents; in addition, copper and zinc can be used chelated (bound) with salicylic acid for similar benefits."-- The Natural Way to Heal by Walter Last, pg 161
Colloidal silver is "freefrom the drawbacks of other preparations of silver, viz-pain caused and discoloration of the skin; indeed, instead of producing irritation it has a distinctly soothing effect. It rapidly subdues inflammation andpromotes healing of the lesions, it can be used with remarkable results in enlarged prostate with irritation of the bladder, in pruritis ani, and perineal eczema, and in haemorrhoids."-- British Medical Journal (May 12, 1917), Sir Malcom Morris
"Colloidal silver has been found to be beneficial for permanently restoring the patency of the Eustachian tubes and for reducing nasopharyngeal catarrh. Colloidal silver has also been used successfully in septic conditions of the mouth (including pyorrhea alveolysis - Rigg's disease), throat (including tonsillitis and quincies), ear (including Menier's symptoms and closure to Valsalva's inflation), and iin generalized septicemia, leucorrhea, cystitis, whooping cough and shingles."-- British Medical Journal (December 15, 1917), J. Mark Hovell
"Silver is an anti-bacterial, anti-viral, anti-fungal anti-metabolite that disables specific enzymes that microorganisms use for respiration. Silver is such an efficient anti-bacteriacidal that our 'great grandmothers put silver dollars in fresh milk to keep it from spoiling at room temperature.'...Silver has been employed in human health care and in the search for immortality since the days of the Chinese alchemist 8,000 years ago. Many feel that silver is in fact an essential element, not because it is required for an enzyme system, but rather as a systemic disinfectant and immune system support."-- Rare Earths, Forbidden Cures by Joel D. Wallach, BS, DVM, ND and Ma Lan, MD, MS
"This liquefied form of silver is a powerful natural antibiotic that can help knock out an acute sinus infection, says John M. Sullivan, M.D., a physician in Mechanicsburg, Pennsylvania. Buy a bottle of colloidal silver, put some full-strength into a spray bottle, and use one or two squirts into your nose twice a day until the infection has been noticeably gone for 3 days."-- Alternative Cures by Bill Gottlieb, pg 553

"Other vitamins that have been proven to help increase fertility in women are: iron (35 mg); folk acid (one mg three times daily), to help normalize blood chemistry; vitamin B12, to help normalize reproductive function; colloidal silver, to help cleanse the system when chlamydia is causing infertility; and bioflavonoids (found in broccoli, green peppers, parsley, and citrus fruits), to help develop a healthy uterine lining."-- Complete Encyclopedia Of Natural Healing by Gary Null PhD, pg 241
"From 1900 to the beginning of the modern antibiotic era - circa 1940 with the introduction of sulfa drugs - Silver was one of the mainstays of medical practice in Europe and America. Various forms of Silver were used to treat literally hundreds of ailments: lung infections such as pneumonia, tuberculosis and pleurisy; sexual diseases such as gonorrhea and syphillis; skin conditions such as cuts, wounds, leg ulcers, pustular eczema, impetigo and boils; acute meningitis and epidemic cerebro-spinal meningitis; infectious diseases such as Mediterranean fever, erysipelas, cystitis, typhus, typhoid fever, and tonsilitis; eye disorders such as dacryocystitis, corneal ulcers, conjunctivitis and blepharitis; and various forms of septicemia, including puerperal fever, peritonitis and post-abortion septicemia. (This list does not even begin to exhaust the published medical uses for Silver in Europe and America, 1900-1940)."-- -- International Anti-Aging Bulletin, April 1999, by James South, MA

"Treat the infection: Your physician can prescribe an appropriate antibiotic to treat the underlying infection. If you are working with a physician who specializes in natural therapies, he or she may suggest the use of colloidal silver, golden seal and/or grapefruit seed extract."-- Digestive Wellness by Elizabeth Lipski MS CCN, pg 274
"Ongoing studies on antibacterial properties of silver...indicate that silver is effective even against bacteria that are already antibiotic-resistant."-- S.M. Foran, Therapeutic Properties of Silver: an Historical and Technical Review
"Small bowel infections, esophageal Candida and other infections are likely to reoccur. No specific research has been done to show that use of supplementation with flora and other natural therapies can help with reoccurrence, but they do help to boost the immune system. You may be able to keep the infection at bay with use of colloidal silver, grapefruit seed extract or garlic capsules. Each of these substances has wide antimicrobial properties, low toxicity and a low incidence of negative side effects."-- Digestive Wellness By Elizabeth Lipski MS CCN, pg 313

"Rashes, including blistering types, are frequently due to what we put on our skin. One cause is soap because it may contain an artificial chemical that produces an adverse reaction. If you have a rash problem, it is advisable to use the type of soap that is 100 percent natural, or at least one that is unscented. A rash can be cleaned with a mixture composed primarily of aloe vera, along with colloidal silver, bee propolis, pau d'arco, and purified water. Then, wrap the area with gauze that is kept somewhat moist, so the mixture remains on the rash. After four or five hours, the rash should begin to heal."-- Power Aging by Gary Null, pg 307
"Persistent bowel problems have been correlated with recurrent UTIs. Our bodies eliminate wastes in several ways, including the excretion of feces by the bowels, the expulsion of carbon dioxide by the lungs, perspiration by the skin, and the discharge of urine by the kidneys and bladder. If any of these processes is malfunctioning, an excessive burden is placed upon the other systems. I do not believe that antibiotics are the proper treatment for UTIs because they do not get to the underlying cause. The proper approach is to rebalance the system by switching from an acidic diet to an alkaline one. Unsweetened cranberry juice with cherries and raspberries, four to five times a day, can ameliorate the severe pain. Pomegranate juice, two times a day, and grapefruit juice with the seeds and the skins are valuable too. Lemon, lime, and bee propolis with 10 drops of colloidal silver are also helpful. Because of the vitamin C content, these juices will create acidic urine (but not acid in the body), which creates an unfavorable environment for bacteria in the urine and bladder. Chlorophyll from spirulina is exceptionally good for the body as well."-- Power Aging by Gary Null, pg 365
"Colloidal silver, which can be found in any health food store, is a powerful antibiotic. It can cure conjunctivitis, or pink eye, as well as simple eye irritation..."Now a great remedy is available for itchy eyes that works like pure magic every time. It's colloidal silver drops. Just two drops in each eye can stop itching for a week or more."-- Proven Health Tips Encyclopedia by American Medical Publishing, pg 197
"Hundreds of thousands of doses of oral colloidal silver and thousands of doses of intravenous colloidal silver are given every month in the United States. This is usually done to treat acute and chronic infections including those associated with chronic fatigue syndrome (CFS) and fibromyalgia (FM).
The effectiveness of the use of oral and intravenous colloidal silver in the treatment of chronic fatigue syndrome and fibromyalgia was presented at the 38th Annual Meeting of the American Academy of Environmental Medicine (Identifying the Causes and Exploring the Newest Treatment Options for Chronic Fatigue Syndrome, Fibromyalgia and Environmental Sensitivities) in October 2003. The extremely low level of colloidal silver used at 23 parts per million (ppm) has been shown to have little or no potential for toxicity while having the significant potential for clinical benefit.
The effectiveness of oligodynamic silver's antimicrobial action at extremely low doses in combination with its potential immune stimulating actions, makes oligodynamic silver an ideal naturally occurring substance in the treatment of CFS and FM."-- Dr. Kent Holtorf, Holtorf Medical Group, "Safety and Efficacy of Intravenous Oligodynamic Silver"
"However, if you store drinking water for a longer time, you can add some colloidal silver or hydrogen peroxide to keep it free of molds and other microbes or possibly put a piece of clean copper or a silver coin at the bottom of the container."-- The Natural Way to Heal by Walter Last, pg 40
"I was told I had second-and third-degree burns on my face and third-degree burns on my hands....the very next day my mother brought me colloidal silver, with directions to use it externally and internally as frequently as possible, because it assists in growth of new tissue. She had learned from Dr. Young that silver's positive electrical charge counters the negative charge of a damaged body area, bringing it back into balance and enabling the body to regenerate and heal itself. Mom sprayed undiluted colloidal silver onto the burned areas, and I took it by drops under my tongue...My mother applied the silver many times a day. It was absorbed into my skin instantly. It felt cool and tingling and loosened the tension on my face, hands, and fingertips...After only one day of treatment with silver, it was obvious the healing was happening very rapidly. New tissue and skin grew back at an accelerated pace. The swelling of my head diminished rapidly and the breathing apparatus came off almost immediately. The plastic surgeon told me I was healing twice as fast as any burn patient he had ever seen in his long career."-- The pH Miracle: Balance Your Body, Reclaim Your Health by Robert O. Young, PhD., pgs 137-138
"At the beginning of your health improvement efforts and several times each year, you can take a remedial course of colloidal silver for several weeks to keep down any undesirable microbes that have arisen in your body. Have a sip or tablespoonful three times daily. Preferably, store colloidal silver in a dark glass bottle in a dark and cool place."-- The Natural Way to Heal by Walter Last, pg 162
"Many people are skeptical of claims that colloidal silver can take away pain and accelerate healing. Nevertheless, these impressive attributes are firmly grounded in medical science. Pain is caused by an interruption of the electrical current that normally flows throughout the body at 50 to 70 millivolts. At the point of injury, the current drops towards zero millivolts. This lack of electrical energy also impedes healing. Silver is a superconductor that bridges the electrical gap and restores healthy current flow. You can prove this to yourself by placing a silver coin on a burn and experiencing instant pain relief. In clinical trials at an FDA-approved laboratory, even silver-coated bandages were proven to have analgesic and regenerative properties."-- Dr. Aundrea Adams, Ph.D, CTN
"Beginning in the 1970s, several independent researchers found that silver ions easily destroy Candida and other fungi. But it wasn't until a pilot study during the mid- 1990s that included human patients suffering from terminal AIDS that medical researchers established solid evidence showing just how quick and effective silver ions can be in the treatment of Candida as well as HIV. In this study, nine individuals who were near death were divided into two subgroups. One group suffered from HIV and a terrible Candida infection. The other group suffered from both HIV and an extreme form of malnutrition (known as Wasting Syndrome). The researchers found that in both groups the colloidal silver was capable of killing pathogens and purging the bloodstream of germ defenses in order to restore the immune system."-- Dr. Jonathan Wright, M.D.
"I have a friend who has suffered for years from chronic pneumonitis, caused by Pseudomonas. Sputum cultures were consistently positive, despite massive doses of horribly expensive antibiotics. Then colloidal silver was suggested, and taken. Sputum cultures since have been negative, and the patient's general health and vitality greatly improved. Her internist can't deny the improvement, but won't attribute it to the silver, of course! It would have occurred anyway; the silver just happened to come on the scene at the right time. Uh-huh."-- Dr. Paul Hine, M.D. (retired ophthalmologist)
"Colloidal silver is a powerful healer, despite irrational FDA opposition to it. Silver has been used medicinally throughout the ages, with great success. And now some very promising research is being done on silver as a cancer treatment."-- Alliance for Natural Health, ANH-USA.org, May 15, 2012

"The best defense against swine flu, or any flu, is the age old remedy of colloidal silver. The metal silver in its colloidal state can be safely consumed and used in the body. Bacteria and viruses cannot develop resistance to colloidal silver. Silver disables a vital enzyme and mechanism in all bacteria and pathogens so that they cannot survive. It is good to take a few teaspoons of colloidal silver daily to maintain health. More colloidal silver should be taken if experiencing illness."-- Babu G. Ranganathan, Pravda

"We have found colloidal silver to be quite effective against all mycoplasma-related organisms that we have tested in vitro."-- Brooks Bradley, Harborne Research Foundation
"Few things in life are as cut-and-dried as the fact that silver is completely safe when used within normal limits."-- Herbert Slavin, M.D., director of the Institute of Advanced Medicine in Lauderhill, Florida
"In addition to its antibacterial properties, silver is also being studied as an antifungal agent. A study published in Mycoses in 2007 indicated that silver is effective against four fungi 'which cause major fungal infections in humans': Trichophyton rubrum, Candida albicans, Microsporum canis, and Aspergillus flavus. Silver has also been studied as an antiviral, and has been shown 'to prevent [certain viruses] from being infective.'"-- S.M. Foran, Therapeutic Properties of Silver: an Historical and Technical Review
"Common substances like table salt and aspirin are harmless with normal use, but excessive intake can become toxic and even life-threatening. With normal responsible usage, silver supplements are entirely harmless to humans."-- Jeffrey Blumer, M.D., Ph.D., director of the Center for Drug Research, former director of the Greater Cleveland Poison Control Center
"Colloidal silver appears to be safe for children and pregnant and nursing women. It is tasteless, odorless, contains no free radicals, is harmless to human enzymes and has no adverse reactions with medications. Taken internally, it may improve digestion, help prevent colds, flu and all organism-caused diseases. It can be used as a douche, atomized, nebulized or inhaled. Applied externally, it has been shown to help with things such as skin abrasions and burns (including sun burn). It can also be dropped into the eyes and ears to help the body overcome infection."-- Kurt Grange, Ph.D., N.D., Nutritional Biophysiologist, author, lecturer
"Sometimes a treatment can be worse than the illness, but not in the case of Colloidal Silver. I have my patients spray or swish Colloidal Silver in their mouths from one to three times daily, depending on the severity of their condition, or, in a dose of one quarter to one teaspoon, and even up to one tablespoon, one to three times daily for situations that are more problematic. I also have them use it in small amounts daily as a preventative...
...A patient I was treating for an ear infection continued to have pain. His ear canal was severely inflamed and had the appearance of what you would think of as a burn. After taking an injection of an antibiotic, as well as using a prescription ear drop and an oral antibiotic for several days, he returned with an internal canal that was bright red and an ear that was tender to the touch. I prescribed 3 Colloidal Silver drops in his affected ear three times daily, and he returned the next day with a 75% improvement...
...Some of my teenage patients with facial skin infections seem to do well with a spray on the skin and into the mouth once or twice daily. Sometimes higher amounts are needed. This certainly beats taking antibiotics for years and years to prevent these skin conditions...It's interesting how many of my patients improve with the use of Colloidal Silver. It enhances the immune system where other antibiotics cause yeast overgrowth...
...Another patient has had persistent yeast infections. Having had no success with both prescription and non-prescription treatments, she called me, at her wit's end. I suggested that she try a douche of two teaspoons of Colloidal Silver in a quart of water. Three days later she was evaluated in my office. The symptoms of her yeast infection had vanished, and there was no visible sign of infection."-- Dr. Ron Surowitz, head of the Florida Osteopathic Medical Association
"...it cannot be contested that silver is a potent germicide. Scientists have proven that colloidal silver destroys virtually all bacteria, viruses, and most other single-celled pathogens within minutes. An article from a 2006 issue of the American Journal of Nursing states:
'Silver is a broad-spectrum agent effective against a large number of Gram-positive and Gram-negative microorganisms, many aerobes [living in the presence of oxygen] and anaerobes [living in the absence of oxygen], and several antibiotic-resistant strains such as methicillin-resistant Staphylococcus aureus and vancomycin-resistant enterococci.'"-- Nenah Sylver, PhD, The Rife Handbook – Chapter 3 excerpt, "Colloidal Silver"
"In medical treatment, Colloidal Silver has been used for the eyes, nose, throat, skin, and everything in-between. It has been proven to promote rapid healing, with less scar tissue. Colloidal Silver solutions have been administered orally, topically, vaginally, rectally, intravenously, intramuscularly, as a gargle, as well as eye and ear drops. It can be atomized or inhaled into the nose or lungs, therefore, safely used in a vaporizer or humidifier for respiratory infections...Some therapists, such as Dr. Becker, use direct application of electrically charged silver rods (his "silver wands") to the skin, using the bodily fluids as the solution medium. The most widely accepted applications of Colloidal Silver are to ingest it or apply it directly to the skin. KEY APPLICATIONS: Infection, Immune Support, Wound Healing."-- The Wonders of Colloidal Silver, by Dyhana L. Coburn and Patrick D. Dignan
"While analyzing hair samples and questioning the parties involved, I noticed the correlation between low silver levels and sickness. People who showed low silver levels in their hair analysis were frequently sick. They seemed to have innumerable colds, flu, fevers, and various other sickness. I believe that a silver deficiency may be the key to the improper function of the immune system."-- Dr. Robert O. Becker, M.D., author, The Body Electric
"...metallic silver in colloidal suspension...yield silver ions in such a quantity as to have a detrimental effect on microorganisms but slowly enough not to be irritating to the tissues. The Colloidal Silver particles provide a continuous source of these ions, yet the particles are not absorbed by the body tissue taken en masse in true solution by the body fluids; consequently, Colloidal Silver can be applied directly to delicate mucous membranes, such as those in the eye, with no irritation and with beneficial results...The colloidal particles diffuse gradually throughout the blood and give prolonged therapeutic action."-- Robert J. Hartman, in his book, Colloid Chemistry
"We have had instant success with Colloidal Silver and immune compromised patients. A few examples are: Pink Eye (topical) totally are solved in less than six hours; recurrent sinus infections (oral ingestion) resolved in eight days; acute cuticle infections - (topical) - twenty four hours. Another major area in which we have improved our clinical results is in the area of bowel detoxification and dialysis. The Colloidal Silver has provided excellent removal of abnormal intestinal bacteria; also it has proved to be a great adjunct to our Candida Albicans, Epstein Barr virus, and Chronic Fatigue Syndrome protocols."-- Dr. Evan M., Kansas, quoted in Colloidal Silver, The Amazing Alternative to Antibiotics
"Research has shown that silver is a powerful antimicrobial agent that is non-irritating and non-toxic."-- Valerie Edwards Jones, professor of microbiology at Manchester Metropolitan University
"Research with the Heart of England NHS Foundation Trust has found that silver, incorporated in the surfaces of hospital equipment furniture, can reduce bacterial levels by 99 per cent. This, in turn, cuts infection risk from superbugs such as MRSA, E. coli and salmonella."-- Dr Richard Hastings, microbiologist for BioCote, Ltd.
"We also have a water purification system that sterilizes the water through the use of silver ions. This product, called Jowa AG-S, has made us world-famous in the shipping industry! This sterilization method provides long-term protection and is a suitable method for long-term storage of drinking water. Since its introduction in 1970, this unit has been installed in thousands of ships. Incidentally, sterilizing water with the help of silver is an old and well-tried method that goes all the way back to antiquity. It is completely harmless to humans and animals and the silver ions do not change the taste or smell of the water."-- The Jowa Group, Technology for Living Oceans
"A recent paper by Das et al. provides the remarkable datum that some 275,000 kg [(605,000 pounds)] of edible metallic silver foil are consumed every year (in food) in India. No known adverse health effects have ever been recorded. This epidemiological evidence that silver as a metal is not toxic in any way needs no further comment. Further support for the obvious safety of consuming metallic silver (Ag0) is in the worldwide consumption of (so called) silver colloids, often made at home in primitive electrochemical cells by probably some millions of citizens, again with no ill effects."-- Das, M. Dixit, S. Khanna, S. K. Journal title Food Additives and Contaminants
"The cover story of the most recent edition of the Journal of the American Chemical Society (JACS) describes how nanoparticles formed by very small numbers of silver atoms can protect against the cell damage caused by ethanol. The study was led by researchers from the University of Barcelona and conducted in conjunction with the Magnetism and Nanotechnology laboratory of the University of Santiago de Compostela. The results of the study show that these clusters of small numbers of silver atoms catalyze ethanol oxidation at similar concentrations to those found in the blood of alcoholics and at values of membrane potential and pH that are compatible with those exhibited by mammalian cells...
...Alcohol has particularly harmful effects on nerve cells, and in the specific case of astrocytes it induces programmed cell-death and an alteration of the actin cytoskeleton. Following application of the silver nanoparticles to ethanol-exposed cells, the actin cytoskeleton shows marked improvements and cell-death does not occur. 'So, the harmful effect of ethanol on astrocytes is mitigated by the silver nanoparticles, which act as a cytoprotective agent,' explains Javier Selva, a lecturer with the Department of Cell Biology, Immunology and Neuroscience and first author of the paper."-- University of Barcelona web site, commenting on the study, "Silver sub-nanoclusters electrocatalyze ethanol oxidation and provide protection against ethanol toxicity in cultured mammalian cells" published in the Journal of the American Chemical Society. DOI: 10.1021/ja907988s
"But Dr. David Weber, an infectious disease and public health expert at the University of North Carolina in Chapel Hill, isn't convinced that silver resistance will prove much of a problem. Resistance to antibiotics occurs quite readily in bacteria once prolonged exposure to, say, penicillin, occurs. But there's little reason to suppose that resistance to silver would develop so easily, he says.
An antibiotic like penicillin works by hitting a bacterium in a limited fashion, at specific sites. Because the killing is done precisely, the bacterium has a good chance of developing a mutation that would confer resistance.
In contrast, silver kills microbes in a broad, unspecific fashion -- like tossing a bomb at a bacterium. It hits many essential points such as a bacterium's entire respiratory system. This makes it much more difficult for silver-resistance to develop.
And even if tolerance did develop, Weber says, increasing the dose of silver the bacterium is exposed to will solve the problem in most cases."-- Los Angeles Times, August 4, 2008, Margaret Woodbury
"Occasionally people with muscle aches, pains, and backaches are improved with silver, probably because these are associated with viral or bacterial infections in the spinal fluid, which traditional antibiotics or colloidal silver cannot reach. Zinc and silver make a very powerful synergistic team as a secondary immune system. Silver is also effective in controlling warts. Angstrom-size silver is the best source."-- Gabriel Cousens, M.D., author, Spiritual Nutrition: Six Foundations for Spiritual Life and the Awakening of Kundalini
"Research on colloidal silver shows it to be an effective resource against infections and pathogens, yet very little is known about it by the general public or the medical profession. Prior to 1938 it was in common use by doctors. According to Alexander G. Schauss, PhD, of Johns Hopkins University, considerable scientific evidence has been published regarding the effectiveness of silver as an antiseptic against 'several hundred pathogenic organisms.' He also points out that silver is not an antibiotic because, by definition, antibiotics are derived from living organisms."-- Ron Garner, author, Conscious Health: A Complete Guide to Wellness Through Natural Means
"Silver was used 1,200 years ago by Egyptians, Romans, Greeks, sailors, and then by the pioneers who populated our country. They used it for various illnesses and to keep their foods and liquids from spoiling. Prior to 1938, before antibiotics, colloidal silver was used by doctors as their main substance to fight bacteria in a more natural way than through the antibiotics they use today. Antibiotics can harm our kidneys and liver functions. Colloidal silver promotes healing."-- A. Gore Gregory, author, Defeat Cancer
"Silver in the colloidal state is highly germicidal, quite harmless to humans and absolutely non-toxic. Rather than in a chemical compound, the silver in the colloidal state may be applied in a much more concentrated form, with correspondingly better results. All virus, fungus, bacterium, streptococcus, staphylococcus, and other pathogenic organisms are killed in three or four minutes upon contact. There are no side effects whatsoever from the highest concentrations."-- Dr. Henry Crooks, quoted from Use of Colloids in Health and Disease
"Several years ago we conducted some rather extensive evaluations of various protocols promising effective results against various pathogenic agents which cause 'food poisoning'. The one protocol, effective against ALL agents evaluated, was colloidal silver. A 5 ppm solution proved effective against all pathogens tested; yielding complete control within 6 to 8 minutes.....regardless of concentration of the pathogenic agent. Control was effected in some solutions as weak as one part of 5 ppm CS,to 50,000 parts contaminated solution. Among the many agents tested were botulinum, campyobacter, salmonella and listeria (bacterial agents); and norwalk-like viruses and hepatitus A (viral agents). Although we did not conduct researches involving the marine form of vibrio vulnificus, generally regarded as the most toxic of food poisons, a facility associated with us---did. Their results, using colloidal silver at 5 ppm, paralleled those of ours....on the pathogens we evaluated."-- Brooks Bradley, Harbone Research Foundation
"Colloidal silver appears to be one of the greatest discoveries in natural preventive health care of all time. When properly prepared, colloidal silver is a completely non-toxic, tasteless, internally and externally applicable, broad-spectrum germ fighter and disinfectant, which can significantly reduce the length and severity of many viral and bacterial infections."-- Zane Baranowski, Colloidal Silver: the Natural Antibiotic
"I regard stable Colloidal Silver as a most useful preparation in Ophthalmic practice."-- Dr. Legge-Roe, Lancet, British Medical Journal, 1915
"Silver happens to be the world's oldest known antibiotic. There's written evidence that the ancient Egyptians made use of it; the ancient Greeks and Romans stored their water, wine, and other liquids in silver vessels to prevent spoiling and contamination; ancient Chinese emperors ate with silver chopsticks, and wealthy Europeans in the Middle Ages used silver utensils to protect themselves from illness (we still call our eating utensils "silverware" despite it being made from other metals these days)."-- Alliance for Natural Health, ANH-USA.org, May 15, 2012
"Silver is a powerful, natural prophylactic/antibiotic, used for thousands of years...It is a catalyst, disabling the particular enzyme that all one-celled bacteria, fungus and virus, use for their oxygen metabolism, they suffocate. Yet it is of no harm to human enzymes or any part of the human body chemistry. And it kills all disease-causing organisms, in six minutes or less, upon contact, even those pleomorphic, no matter how they mutate. Resistant strains fail to develop, and the body doesn't develop a tolerance. Colloidal Silver is both a remedy and a prevention of infections of many kinds. Having sufficient Colloidal Silver in your body is to have a superior, second immune system. It was in common use until 1938. Great Grandma put a silver dollar in the milk, to keep it fresh at room temperature."-- Health Consciousness magazine, Vol. 15 No. 4
"Silver is the best all around germ fighter we have...The value of silver in medicine, and as a purifier has been acknowledged for centuries. Egyptians implanted silver plates into skulls with surgery. In Ancient Greece and Rome, people used silver containers to keep liquids fresh. When settlers moved across the American West, they would purify a container of water by putting a silver dollar in it overnight. Towards the end of the 19th century, other medicinal uses for silver were developed including the use of silver and mercury in filling cavities, and the dropping of a silver filtrate solution into the eyes of newborn babies to prevent blindness due to infection."-- Dr. Harry Margraf, Biochemist, The Story of Silver in Medicine; Gold & Silver Newsletter, September 1974
"Many strains of pathogenic microbes, viruses, fungi, bacteria or any other single celled pathogen resistant to other antibiotics are killed on contact by colloidal silver, and are unable to mutate. However, it does not harm tissue-cell enzymes and friendly bacteria."-- Ron Barnes, PhD., Pharmacist, Capital Drugs
"Scores of independent tests have shown that silver promptly kills bacteria in water and maintains water purity over long periods of time."-- The Silver Institute Letter, December 1976, Tests Show Silver Best Water Purifier
"The most dramatic purification tests occurred in 1976 in a 20,000 gallon swimming pool in Nebraska. There was no disinfectant of any kind in the water. Fifty gallons of municipal sewage waste water was put into the pool. That produced a dangerous concentration of 7,000 E.Coli cells per 100 millilitre [half a cup] of water. Contents of the pool were then pumped through a tank containing silver for disinfection. Within three hours the pool was entirely free of e.Coli and the water contained only 3.2 parts of silver per billion parts of water (0.0032ppm).-- The Silver Institute Letter, May 1975, Silver Guards Good Health
"The Allegheny County Health Department in Pennsylvania conducted tests in a 152,000 gallon pool which previously had been disinfected by a 50 pounds per day chlorinator. The system was replaced by a silver system for the swimming pool season. The County Health Department took up to 50 daily samples and found that silver ions remained in the pool at the low steady rate of 20 parts per billion (0.02ppm). The water remained free of bacteria throughout two seasons. In contrast, 65 water samples from 30 other pools having a concentration of 700 parts per billion (0.7ppm) of available chlorine showed a mean of 1.3 pseudomonas and 7.3 staph cells per millilitre of water."-- The Silver Institute Letter, May 1973, Silver Carbon Filter Purifies Swimming Pool
"Silver compounds have a wide variety of uses as caustics, astringents, antiseptics, and germicides. Their activity resides in the silver ion, which is a protein precipitant. It is toxic to bacteria by precipitating the protein in the bacteria protoplasm. Colloidal silver preparations, in which the silver does not exist to any large extent as free ions, act by the milder and sustained antiseptic effect brought about by the formation of a protein silver compound which slowly liberates small amounts of ionic silver. Colloidal silver compounds, contain very little ionizable silver . Use of any silver preparation over a long period may cause permanent blue discoloration of the skin and mucous membranes, (particularly the lips and under the fingernails) known as Argyria. There are no known adverse health effects of Argyria. The colloidal silver preparations contain high concentrations of silver, largely in non-ionized form. Their antiseptic value depends on the activity of the free silver ions and not on their content. They do not precipitate protein but penetrate the tissues. Those mentioned here are silver proteins and silver halides."-- Handbook of the Hospital Corps of the United States Navy, 1953
"Big Pharma hates silver. Pure and simple. It's too competitive. It allows the little guy a way of taking care of infectious illness without using pharmaceutical drugs. On the broader level, Big Pharma and the ruling elite know extremely well that the less nutrition a consumer gets his hands on, the more prone he is to become malnourished and end up at a doctor's office with symptoms of some disease that requires prescription drugs."-- Anders Sultan, Sweden's largest colloidal silver manufacturer, maker of the Ionosil brand
"The efficacy of AgNPs (i.e, silver nanoparticles) against HIV-1 has been reported by many laboratories including ours [19,26]. It has been shown that AgNPs have got anti-HIV-1 activity and can help the host immune system against HIV-1. This has laid ground for the development of new, potent antiviral drugs capable of preventing HIV infection and controlling virus replication. Recently, it has been demonstrated that AgNPs function as broad-spectrum virucidal and bactericidal agents, and in addition, increase wound healing."-- Journal of Nanobiotechnology, September 2011, "Silver nanoparticles are broad-spectrum bactericidal and virucidal compounds," Humberto H Lara, Elsa N Garza-Treviño, Liliana Ixtepan-Turrent and Dinesh K Singh
"I know of nothing which could quite take its place, nor, have I known anyone to abandon it who had thoroughly familiarised himself with the technique of its application. We may only have scratched the surface of silver's medical brilliance! Already it is an amazing tool! It stimulates bone - forming cells, cures the most stubborn infections of all kinds...and stimulates healing in skin and other soft tissues".-- Dr. William Steward Halsted, 1913

"The wide antimicrobial spectrum, the high microbicidal potency, the good water solubility and the safety of anodic silver, therefore, provide an encouraging background to the investigation of the use of this ion as a preservative in pharmaceutical or cosmetic formulations...The high rate of kill of anodic silver is very useful to ensure a rapid reduction of microorganisms. However, the effectiveness of silver in keeping the number of surviving organisms at less than 0.01% of the starting inoculum after repeated inocula, even in the presence of strong interfering additives, appears the most interesting feature for its possible use as a preserving agent in multiple-dose products".-- Scalzo, M., et al. 1996.

"Silver, a well-known antimicrobial agent, has been used in clinical settings for more than a century. During this period, the safety of this agent has been well established. In addition to being effective against fungi, this method of silver application has also been demonstrated to be efficacious against a broad spectrum of bacteria, including antibiotic-resistant strains. The results of the current study demonstrate the excellent in vitro performance of silver, particularly the nanocrystalline form, against a variety of common fungal pathogens.

"Electrically generated silver ions have been shown previously to be a potent antibacterial agent with an exceptionally broad spectrum...The present study reports on clinical experience using electrically generated silver ions as adjunctive treatment in the management of chronic osteomyelitis...wound care (usually provided by the patient) resulted in control of the infection in twelve of the fifteen treatment attempts and in healing of the non-union after follow-up ranging from three to thirty-six months. In this small series, the silver ions seemed to have been an effective local antibacterial agent with advantages over other antibiotics that included: activity against all of the bacterial types encountered in these patients, negligible toxic effect on local tissues, and penetration of poorly vascularized tissue to the distance believed to be about one centimeter. The rapid subsidence of the infection once treatment with silver ions was initiated convinced us that the silver iontophoresis had had a beneficial antibacterial effect. An added benefit, which was unexpected, was the deposition of substantial amounts of new bone produced during treatment with the silver-nylon anode."-- Becker, Robert O., and Spadaro, Joseph A. 1978.

Proved cases of chronic osteomyelitis, with or without pathological fractures and septic non-unions, wound care yielded not only control of bone infections in 85% of cases, but also produced healing of pathological fractures in 83% of patients. In the present series, silver ions have been used as an effective local antibacterial agent with multiple advantages over many conventionally used methods with or without antibiotics. Silver ions are not only effective in different cases, where bacteria had become resistant to most of the commonly used antibiotics but also have only negligible toxic effects on tissues. No patient was subject to this treatment without waiting for outcome from previous treatment."-- Nand, Sanjiv, et al. 1996.

Silver anode treatment of chronic osteomyelitis. Clinical Orthopaedics and Related Research. 161: 105-114.
"A method of producing local antibiotic effects by means of an iontophoretic technique using free silver ions has been evaluated in vitro and in vivo for more than two decades. The antibiotic properties of the technique have proved useful in both animal and human studiesBeginning in 1973, in vitro studies demonstrated that such ions were an effective antibiotic with a very broad spectrum and favorable quantitative evaluations compared with synthetic antibioticsThe failure of other nontoxic metal ions to produce a similar alteration with the same electrical parameters strongly indicates that the electrically generated silver ion is the agent responsible for the observed cellular changesHealing rates in these wounds are significantly accelerated and are accompanied by enhanced healing of the bone, soft tissue, nerve, and skin, with replacement of missing tissues by histologically normal tissuesThe responsible agent for these cellular effects is believed to be the electrically generated silver ion."-- Becker, Robert O. 2000.

"The US Food and Drug Administration has approved silver compounds for clinical use and various versions have been formulated by compounding pharmacies. Silver nitrate is used in the eyes of newborns to prevent blindness. Concentrated silver nitrate is used topically on mucus membranes to stop bleeding. Silver sulfadiazine is used for the treatment of burns and to prevent sepsis or bacterial infection in severe burns. Silver formulations have also been used in hundreds of various infections and other conditions including pneumonia, tuberculosis, STD's, eczema, meningitis, erysipelas, Mediterranean fever, corneal ulcers, conjunctivitis and septicemia."-- Dr. Kent Holtorf, Holtorf Medical Group, "Safety and Efficacy of Intravenous Oligodynamic Silver"
"New research, published in the European journal ChemMedChem, shows that silver modifies cytokines, the enzymes involved in cell growth and movement. This modification of cytokines leads to reduced inflammation and an increased rate of healing. Since the inflammation response contributes to—or in some cases, directly causes—some diseases, using silver for healing shows great promise. Not only can cells function more normally, but if the immune response is more efficient, viruses can be eliminated even more quickly."-- Nenah Sylver, PhD, The Rife Handbook – Chapter 3 excerpt, "Colloidal Silver"

Study Synopsis: Collargol (colloidal silver protein), silver nitrate, and a mixture of Collargol and silver nitrate (colloidal silver complex) were tested for antibacterial efficiency against S. aureus, A. aerogenes, and P. aeruginosa in water, human plasma, and trypticase soy broth. The presence of proteins significantly decreased the antibacterial efficacy of all 3 agents tested. Colloidal silver complex and silver nitrate inhibited the bacteria in water at 2.5 ppm, while a concentration of 100 ppm of Collargol was required to inhibit the bacteria in water. In trypticase soy broth, the silver nitrate and colloidal silver complex required concentrations of 100 ppm to inhibit the bacteria, while the Collargol required a concentration of 1000 ppm to inhibit the bacteria in the same medium. In human plasma, the inhibiting concentration of silver nitrate was 100 ppm, while the inhibiting concentration of colloidal silver complex was 1000 ppm, and the inhibiting concentration of Collargol was 5000 ppm.-- Brentano, Loreno et al. 1966.

Recently, researchers at the University of Texas and Mexico University began using silver nanoparticles to kill Staphylococcus aureus. Then, in the Journal of Nanotechnology, they reported their groundbreaking findings that silver nanoparticles kill HIV-1, and that they expect silver to kill virtually every other virus as well! The silver particle size ranged from one to ten nanometers.

"Silver is non-toxic, safe inorganic antibacterial agent being used for centuries and is capable of killing about 650 microorganisms that cause disease. Silver has been described as being 'oligodynamic', that is, its ions are capable of causing a bacteriostatic (growth inhibition) or even a bactericidal (antibacterial) impact. Therefore, it has the ability to exert a bactericidal effect at minute concentrations. It has a significant potential for a wide range of biological applications such as antibacterial agents for antibiotic resistant bacteria, preventing infections, healing wounds and anti-inflammatory. Silver ions (Ag+) and its compounds are highly toxic to microorganisms exhibiting strong biocidal effects on many species of bacteria but have a low toxicity toward animal cells."-- Muhammad Raffi, Synthesis and Characterization of Metal Nanoparticles, Department of Chemical and Materials Engineering, Pakistan Institute of Engineering and Applied Sciences
"Beginning in 1973, in vitro studies demonstrated that such
[electrically generated silver] ions were an effective antibiotic
with a very broad spectrum and favorable quantitative evaluations
compared with synthetic antibiotics (2-5). Animal studies
indicated equal efficiency in experimental osteomyelitis in
rabbits with no acute deleterious side effects (6). In all
studies, precautions were taken to avoid overt electrolysis,
which would have introduced erroneous results in vitro and
produced tissue damage in clinical use. The level of voltage
required to produce measurable electrolysis in human soft tissue
with silver wire electrodes was determined to be approximately
1.1 volts (7). Accordingly, applied voltage in all studies was
limited to 0.9 volts or less.
"Silver has been used for centuries as an antimicrobial agent to reduce bioburden and prevent infection. Its usage diminished when antibiotics were introduced but remained one of the most popular agents for wound infections, especially in burned patients. Incorporation of silver into a range of hygiene and healthcare applications has increased, and this has raised concerns over the development of silver resistance, toxicity, methods of testing products and evidence of efficacy. The published evidence for resistance and toxicity is limited and associated with frequent and high levels of silver used. Increasing evidence of improved antimicrobial activity of nanoparticles of silver and possible dual immunomodulatory effects are exciting. This may lead to further product development as potential alternative preservatives as some currently available preservatives have an increasing incidence of allergic reactions. Acknowledging the role of the carrier is important, and as silver is active when in solution, opens a window of opportunity in personal hygiene area. This is important in an age when multiple antibiotic–resistant bacteria are becoming prevalent."-- Letters in Applied Microbiology, V. Edwards-Jones, The benefits of silver in hygiene, personal care and healthcare
"Silver has been used for at least six millennia to prevent microbial infections. It has been effective against almost all organisms tested and has been used to treat numerous infections and noninfectious conditions, sometimes with striking success. Silver also has played an important role in the development of radiology and in improving wound healing...Silver was the most important antimicrobial agent available before the introduction of antibiotics. Historically, silver has been a major therapeutic agent in medicine, especially in infectious disease, including surgical infections.

"Colloidal silver is powerfully destructive of toxins of bacterial origin, though whether the reaction is purely physical or in part chemical is not known. Experiments on rabbits show that colloidal silver renders subject 'immune' from the effects of large quantities of tetanic or diphtheritic serum. Properly prepared, it is extremely stable, and is unchanged till at any rate the intestine is reached. It has been proved most useful in the treatment of diseases of the eye, the nose, and the ear, as well as in septiceamia when administered by intravenous injection. C.E.A. MacLeod says (Lancet, February 3, 1912) that colloidal silver has proved its value in combating the following ailments among others -- tonsilitis, gonorrhoeal conjunctivitis, spring catarrh, pustular eczema of scalp, septic ulcers of legs, boils, chronic cystiitis, ringwork, soft sores. But we must not prolong the list of the good works of colloidal silver.

"Colloidal Silver as a Specific -- Dr. P. Viett advocates the use of colloidal silver as an efficient means of combating sepsis. He reports a number of illustrative cases, all resulting favorably. Should his results be substantiated, a distinct advance step in therapeutics can be recorded. He has used the unguentum Crede' in larger doses than those usually prescribed (forty-five grains), using it in one inunction. In patients suffering from phlegmon, lymphangitis, and lymphadenitis his results were excellent. In one case of pneumonia inunctions over the chest were employed. The patient recovered promptly, but on special credit is given to the therapy, save that recovery began almost immediately after the use of the remedy. In two severe toxemic cases of scarlet fever and in one of diphtheria favorable results followed promptly after the introduction of the treatment. The results were equally striking in two patients suffering apparently from acute appendicitis. Three patients suffering from puerperal sepsis recovered. From his experience in the twenty cases reported, the author is led to believe that as an effective agent against various pyogenic organisms colloidal silver should be regarded as taking first place, and that the results are certainly encouraging that an internal antiseptic has been made practicable."-- The American Journal of Medical Sciences, Volume 121, page 605, 1901

The collargol used is that obtained by the disintegrating action of electricity (electrargol) and assumed to be much purer than that obtained by chemical measures. The properties of colloidal silver are, therapeutically, the following: antiseptic, inhibiting bacterial growth, inorganic ferment exercising catalytic action. The drug is absolutely harmless and should be used (1) when at the outset the infection assumes a serious aspect; (2) when an infection, at first localized, tends to become generalized."-- Post-Graduate, Volume 23, #10, page 911, New York Post-graduate Medical School and Hospital, October, 1908
"Schlossmann, of Leipsig, reports extensive experiments with colloidal silver in acute conjunctivitis, and especially in gonorrhoeal ophthalmia. One to five per cent. albuminous solutions were employed, being applied to the conjunctiva by means of a camel's-hair brush. The results were very excellent in all cases, and he places the drug at the head of all the remedies at our disposal for the treatment of this often so obstinate affection. The instillations were entirely painless. Improvement began with the first application, and not infrequently the childten were discharged cured after four or five days. Schlossmann also employed colloidal silver internally in acute intestinal catarrhs of infectious origin. A teaspoonful of the one per cent. albuminous solution was administered with a little milk or syrup every hour or two, the children taking it willingly. It is possible that the improvement may have been partly due to the simultaneous regulation of the diet. But the author recommends the colloidal silver to all practitioners who treat these infectious intestinal affections with intestinal antiseptics, as worthy of a place in the very first ranks of the drugs available for that purpose. Besides its great antiseptic power, it has the advantage of being absolutely non-poisonous."-- Interstate Medical Journal, Volume 7, #10, October, 1900
"Schlossmann (Therapcut. Monatshefte, May, p. 278) has

"...the mechanism of action of AgNPs (i.e., silver nanoparticles) as an antiviral and virucidal has been studied against several enveloped viruses. Recently, it has been suggested that nanoparticles bind with a viral envelope glycoprotein and inhibit the virus by binding to the disulfide bond regions of the CD4 binding domain within the HIV-1 viral envelope glycoprotein gp120, as suggested by Elechiguerra and colleagues. This fusion inhibition was later elegantly demonstrated by Lara and colleagues in their latest report.
The antiviral effects of AgNPs on the hepatitis B virus (HBV) have been reported using a HepAD38 human hepatoma cell line. There has been evidence of high binding affinity of nanoparticles for HBV DNA and extracellular virions with different sizes (10 and 50 nm). Moreover, it has been demonstrated that AgNPs could also inhibit the production of HBV RNA and extracellular virions in vitro, which was determined using a UV-vs absorption titration assay. Further investigation will be needed to determine whether this binding activity prevents HBV virions from entering into host cells or not.
In an another report Sun and colleagues showed that AgNPs were superior to gold nanoparticles for cytoprotective activities toward HIV-1-infected Hut/ CCR5 cells. It is generally understood that Ag, in various forms, inactivates viruses by denaturing enzymes via reactions with sulfhydra, amino, carboxyl, phosphate, and imidazole groups. However, it is necessary to design studies in vivo to increase therapeutic benefit and minimize adverse effects. Among antiviral activities, the capacity of AgNPs to inhibit an influenza virus was determined in a MDCK cell culture and was demonstrated that with AgNPs at 0.5 ìg/ml concentration viral infectivity was reduced. Nanosilver may interfere with the fusion of the viral membrane, inhibiting viral penetration into the host cell.
Lara and colleagues further demonstrated that AgNPs inhibited a variety of HIV-1 strains regardless of their tropism, clade and resistance to antiretrovirals. The fact that AgNPs inhibited number of HIV-1 isolates suggest that their mode of action does not depend on cell tropism and that AgNPs are broad spectrum anti-HIV-1 agents. A cell-based fusion assay using Env expressing cells (HL2/3) and CD4 expressing cells mixture demonstrated that AgNPs efficiently blocked cell-cell fusion in a dose-dependent manner within the 1.0-2.5 mg/mL dose range including: Tak-779 (Fusion Inhibitor), AZT (NRTI), Indinavir (PI) and 118-D-24 (Integrase Inhibitor) as controls (Figure 2). In addition, efficient inhibitory activity of AgNPs against gp120-CD4 interaction was measured in a competitive gp120-capture ELISA. The results of the cell-based fusion assay confirm the hypothesis that AgNPs inhibit HIV-1 infection by blocking the viral entry, particularly the gp120-CD4 interaction.
Other studies also showed that AgNPs at non-toxic concentrations effectively inhibit arenavirus replication during the early phases of viral replication."-- Journal of Nanobiotechnology, September 2011, "Silver nanoparticles are broad-spectrum bactericidal and virucidal compounds," Humberto H Lara, Elsa N Garza-Treviño, Liliana Ixtepan-Turrent and Dinesh K Singh
"We measured the silver levels produced in vitro by three silver-coated fabrics, and the resulting antimicrobial effect on Pseudomonas aeruginosa, Staphylococcus aureus, and Candida albicans. A significant enhancement of the fabrics' antimicrobial effect was achieved by the passage of weak DC currents, which cause increased liberation of silver ions. The antimicrobial effectiveness of each fabric depended on its textile characteristics. Thus, a silver-coated fabric could potentially serve as an antimicrobial dressing by continuously releasing silver ions into a wound either by passive dissociation or through electrical stimulation."-- Journal of Biological Physics, Volume 12, Number 4, 1984, Electrical augmentation of the antimicrobial activity of silver-nylon fabrics
"Silver has been known for years for its broad spectrum antimicrobial properties. Colloidal silver was used in wound antisepsis and in combination with citrate salts for skin infections. One to two percent silver nitrate was employed almost 100 years ago for the treatment of ophthalmia neonatorum. Shortly thereafter silver acetate was formulated into eye lotions and creams, silver nitrate (0.01%) was used in bladder irrigations and silver lactate (1 : 100 to 1 : 2500) was employed as a general antiseptic . Silver sulfadiazine, the non-ionized, water-insoluble powder (1%) was applied in creams for treatment of burn wounds and prevention of infections by Fox in 1968  and is currently still in use. Colloidal preparations of silver salts are still used medically for local antiseptics on mucous membranes, silver acetate-containing antismoking lozenges, and coatings for breath mints. Other medical applications of silver involve silver-coated nylon fabrics that are used to treat and manage postoperative debridement wounds in cases of severe chronic osteomylitis and antimicrobial Foley catheters [3,9,11,14]. Aside from medical uses, silver is employed in water treatment partly because of concerns about the production of possible carcinogens during the disinfection of water with chlorine. Various silver-treated charcoal filters that remove odors and reduce organics in drinking waters are commercially available. Also, various ionization apparatus that produce low levels of silver ions (<0.5/zl m1-1) are manufactured for microbial control in recreational pool waters."-- Journal of Industrial Microbiology (1995) 15, 372-376
"The susceptibility of Escherichia coli B to the antibacterial activity of silver ions was measured in terms of the initial inhibitory concentration, complete inhibitory concentration, postagent effect for bacteriostatic susceptibility, minimum bactericidal concentration, maximum tolerant concentration, and log killing time for bactericidal activity. At a concentration of 9.45 M and an inoculum size of 10 CFU ml, silver caused growth delay of E. coli; at a concentration of 18.90 M, silver completely inhibited bacterial growth."-- BioMetals, Volume 11, Number 1, 27-32, 1998
"It has been established that certain heavy metals including silver have antibacterial properties, and that they may be useful components of antibacterial materials. This knowledge of the antibacterial activity of silver has already been put to use to decrease the occurrence of urinary catheter infections and to develop topical antibacterial agents for burn victims. In this study, the ability of silver-coated ceramic beads (Ag-CBs), sintered at 375, 400, 425, or 450 °C, to sterilize Sphingomonas sp. in commercial mineral water was evaluated. Over 3% (w/v) Ag-CBs in mineral water completely sterilized Sphingomonas sp. after 6 h, regardless of the sintering temperature. The Ag-CBs sintered at 400 °C were the most useful since they did not produce clouding in the water and the bacteria were effectively killed. The antimicrobial activity of the 400 °C-sintered Ag-CBs was comparable to that of free silver ions at 15 µg/l, showing that the silver ions released from the Ag-CBs resulted in the complete sterilization of the microbial cells in mineral water. These results suggest that Ag-CBs present an easy-to-use option for mineral water sterilization."-- World Journal of Microbiology and Biotechnology, Volume 21, Numbers 6-7, 921-924, 2005
"Research designed to prevent human beings from being infected by microorganisms such as bacteria, molds, yeasts, and viruses from the living environment has attracted tremendous interest. Therefore, many researchers have tried to develop novel and effective antimicrobial materials with free of resistance and low cost [1, 2]. One of the most widely used antibacterial materials is based on silver (silver ions or silver nanoparticles) which exhibits strong biocidal effects towards a broad range of microorganisms, along with advantages such as a lack of odor, taste, and color [3– 6]."-- J Mater Sci, 45:3106–3108, 9 March, 2010, Facile method of preparing silver-embedded polymer beads and their antibacterial effect
"Infections caused by drug-resistant microorganisms result in significant increases in mortality, morbidity, and cost related to prolonged treatments. The antibacterial activity of silver nanoparticles against some drug-resistant bacteria has been established, but further investigation is needed to determine whether these particles could be an option for the treatment and prevention of drug-resistant microbial infections. Hence, we challenged different drug-resistant pathogens of clinical importance (multidrug-resistant Pseudomonas aeruginosa, ampicillin-resistant Escherichia coli O157:H7 and erythromycin-resistant Streptococcus pyogenes) with a suspension of silver nanoparticles. By means of a luciferase-based assay, it was determined that silver nanoparticles (1) inactivate a panel of drug-resistant and drug-susceptible bacteria (Gram positive and Gram negative), (2) exert their antibacterial activity through a bactericidal rather than bacteriostatic mechanism, and (3) inhibit the bacterial growth rate from the time of first contact between the bacteria and the nanoparticles."-- World J Microbiol Biotechnol (2010) 26:615–621

"Metallic silver was known to the Chaldeans as early as 4,000 B.C.E., and it was the third metal known to be used by the Ancients, after gold and copper . Over these millennia, silver has been used for numerous medical conditions, mostly empirically before the realization that microbes were the agents of infection. The metal was used in many configurations, including vessels or containers for liquid, coins, shavings, foils, sutures, solutions (e.g., nitrate, oxide, bromide, chloride, and iodide), colloids providing fine particles, and electric colloids (introduced in 1924, which provide even smaller particles of 0.1mcm to 0.001mcm in diameter). Electric colloids of silver became the mainstay of antimicrobial therapy in the first part of the 20th Century until the introduction of antibiotics in the early 1940s. Complexes of silver and protein known as mild silver proteins also were employed. These formulations were delivered topically (by solution, ointment, or direct application of colloids or foils), orally, and by injection. By 1940, at least 50 silver products were marketed in the United States."-- Surgical Infections, Volume 10, Number 3, 2009, J. Wesley Alexander, History of the Medical Use of Silver
"From Crede's practice scores of cases have been reported in which this treatment attained marvelous results in various forms of septic infection. Werler, of Berlin, regards it as almost a specific in acute and chronic sepsis. Wolfran, of Magdeburg-Buchan, finds it a valuable agent in acute and chronic infections. In chronic furunculosis particularly have the results been most gratifying. Dr. Shirmer, of New York, reported several cases of cerebro-spinal meningitis cured by daily inunctions. Seabury Jones has reported a remarkable case of puerperal sepsis which rapidly subsided under this treatment. Crede states that he has had no deaths from sepsis in his surgical hospital since the introduction of silver salts and colloidal silver. There seems, therefore to be quite a large number of clinical cases reported to induce the clinician to give this medicament a trial. It is stated that eight to twelve hours after the inunction the temperature falls and all symptoms of sepsis become ameliorated."-- The Therapeutic Value of Soluble Silver, John Zahorsky, M.D., Medical Review, May 6, 1899
"In Ayurvedic medicine silver is used in small amounts as a tonic or elixir or rejuvenative agent for patients debilitated by age or disease. Silver was also used in homeopathic medicine. The dilute concentrations were in the same range as the modern low concentrations of colloidal silver. Recently, with the development of antibiotic resistance in many diseases and the increase in new strains of bacteria and viruses worldwide, there is renewed interest in silver. Large companies are developing and introducing new silver compounds for a variety of anti-microbial applications, including protection against the spread of the AIDS virus."-- Colloidal Silver: A Literature Review: Medical Uses, Toxicology & Manufacture, by John Hill
"An experimental investigation of the Christiansen-effect applied to colloidal silver was made. The method employed was to vary the refractive index of the liquid by means of other solvents and noting whether the colour-changes were in accord with theory. The colloidal silver was made by Carey Lea's method from silver nitrate by means of Rochelle salt and ferrous sulphate. The results obtained show that: (1) Colloidal silver solutions of all colours can easily be prepared from one set of reagents, by simply varying the conditions. (2) The colour-changes in colloidal silver solutions are not satisfactorily explained by the Christiansen refractive index phenomenon. A colour-change produced by increasing the refractive index of the liquid is not reversed when the refractive index is again diminished. (3) Light is essential to the changes of colour, and the velocity of these changes depends on the intensity of the light. (4) The colour of colloidal silver is due to a selective light absorption. The author concludes that there is only one form of colloidal silver, not several allotropic forms, and the various colours and properties, such as electrical conductivity, density, action towards reagents, are to be explained by the state of aggregation or number of the particles of this colloidal form.

effective against a broad range of microorganisms. Today, silver
ions are used to control bacterial growth in a variety of medical
applications, including dental work, catheters, and the healing
of burn wounds (17, 30, 31). Silver ions are also used for a
number of nonmedical purposes, such as in electrical appliances

"Textiles are appealing materials for use in several medical applications, including hospital uniforms and linens; prosthetic valves; and wound dressings. One promising innovation is to impart these textiles with antimicrobial properties. Noble metals such as copper, gold, and silver have broad-spectrum antimicrobial activity. For example, silver has several effects on microorganisms, including impeding the electron transport system and preventing DNA replication. Nanocrystalline silver provides Ag0 and Ag+ ions to the surrounding environment. As silver ions are depleted, an equilibrium shift allows additional Ag0 and Ag+ ions to be liberated from nanocrystalline silver. In previous studies, silver has demonstrated antimicrobial activity against a broad range of fungi, viruses, and bacteria."-- Journal of Materials Engineering and Performance, "Antifungal Textiles Formed Using Silver Deposition in Supercritical Carbon Dioxide," Volume 19(3) April 2010, Page 368

On the other hand, as mentioned in Chapter 8, we found that we could suspend mitosis in the fibrosarcoma cells with silver ions injected by minute levels of positive current.

"Silver attacks all three of the germ's vulnerable targets at once. First, the silver ions easily rupture a germ's outer membrane when present in the right amounts, causing the germ's vital internal components to be exposed in the bloodstream to our white blood cells. While the white blood cells attack the internal components, the micro-particulate silver continues to destroy these vital internal components by cutting up vital enzymes. The silver ions then easily attack the germ's third vulnerable target: its delicate gene pool. Silver ions have the ability to reach into the nucleus of the germ, where its gene pool is located. Once they combine with the genes, the genes become paralyzed, and the germ cannot replicate itself...In 1909, the Journal of the American Medical Association was the first medical journal to point out that colloidal silver could actually increase our immune cells' phagocytic index. In the past few years, more studies have shown that silver ions greatly enhance the essential second part of the phagocytic index-the part where the germ is digested by our immune cells. This is brought about because silver ions increase the "digesting juices" (what you know as hydrogen peroxide) of these immune cells."-- Dr. Jonathan Wright, M.D., Tahoma Clinic, Washington State, Stop Supergerms in Their Tracks With One Powerful Silver Bullet
"The government and other skeptics often claim that colloidal silver can cause argyria—a condition in which the skin turns bluish gray. However, argyria has only been found to occur in response to prolonged exposure to or ingestion of silver compounds, especially silver salts, which are not present in true colloidal silver but are found in cheap imitations.
This was demonstrated rather dramatically in 2008 by Paul Karason, the fellow whom the news media dubbed the "Blue Man." Although the news media continually reported that he was taking colloidal silver, interviews with Mr. Karason indicated that was apparently making his own silver compounds at home and ended up making silver chloride—a silver salt—which he both consumed in excessive quantities and regularly smeared on his skin before using tanning beds!

"Recently, due to the emergence of antibiotic-resistant bacteria and the use limitations of antibiotics that can cause serious diseases and is an important public health problem (Furuya & Lowy, 2006), the synergetic effect of silver nanoparticles with antibiotics has been studied combinating silver nanoparticles with different antibiotics like ampicillin, kanamycin, erythromycin and chloramphenicol against gram positive and gram negative bacteria. The antibacterial activities of these antibiotics increase in the presence of silver nanoparticles against gram positive and gram negative bacteria determined by the disk diffusion method. Different diameters of inhibition zones have been shown around the different antibiotic disk with or without AgNPs. The combination effect of nanosilver and ampicillin has more potential compared to the other antibiotics and may be caused by both, the cell wall lysis action of the ampicillin and the DNA binding action of the silver nanoparticles (Fayaz et al., 2009). The antibiotic molecules contain many active groups such as hydroxyl and amido groups, which reacts easily with silver nanoparticles by chelation, for this reason, the synergistic effect may be caused by the bonding reaction with antibiotic and silver nanoparticles."-- Silver nanoparticles interactions with the immune system: implications for health and disease, Rebecca Klippstein, Rafael Fernandez-Montesinos, Paula M.

"Silver nanoparticles exhibit a broad size distribution and
morphologies with highly reactive facets. The major mechanism
through which silver nanoparticles manifested antibacterial
properties is by anchoring to and penetrating the bacterial cell
wall, and modulating cellular signalling by dephosphorylating
putative key peptide substrates on tyrosine residues.
"Since the introduction of colloidal silver into therapeutics by Crede, much interest is being taked in the colloidal state of metals. The peculiar properties of metals in a finely-divided state have long been known, particularly marked in the case of platinum. In 1889, Carey Lea obtained a number of precipitates of silver by the use of reducing agents on silver salts, and found these substances soluble in water. He termed them colloidal silver. Other metals, such as platinum, gold, etc., have been obtained in this colloidal state. The usual way of preparing a colloidal solution is to immerse bars of the metal in water and pass a strong electric current through them, the water acting as a strong conducting medium from one to the other. The metal is broken off in very minute particles and remains suspended in the water...The principal property of the metal in such a fine state of division is its oxidizing power. This is called its catalyzing property."-- St. Louis Courier of Medicine, Volume 27, July-December, 1902
"Silver itself has been shown to be harmless to normal human tissue. No toxic levels are known for properly made colloidal silver. As the Journal of Burn Care Rehabilitation reminds us, any possible toxicity results from the salts or complexes that are used to deliver the silver. This is why using pure silver is the ideal approach to avoid local toxicity. Despite the nontoxic nature of CS, this doesn't stop the pharmaceutical industry -- and its numerous allies, including the FDA -- from circulating misinformation about CS. This acts as a strong deterrent to people from making and using this inexpensive and effective ingredient."-- Nenah Sylver, PhD, The Rife Handbook – Chapter 3 excerpt, "Colloidal Silver"
"B. Crede's first publication on "Silver and Silver Salts as
Antiseptics" appeared in 1896. That pamphlet was followed by many
journal articles since, also by a paper read by him during the
meeting of the Moscow International Medical Congress in 1897.
"Solomon Solis Cohen, Philadelphia, writing on the subject,
(Saint Louis Med. Rev., February 24, 1906) says that the
knowledge of the power of colloidal silver (collargol) in septic
and septico-toxic conditions should be made more general. He has
seen two recoveries from malignant endocarditis and numerous
recoveries from other grave infections by its energetic
employment intravenously and per rectum.
"Recent researches by Crede have shown that colloidal silver
can be used with success in cases of septic peritonitis, and also
in those cases where it is intended to guard the healthy
peritoneum from septic products. The silver is given in the form
of a pill. Each pill contains 0.05 argent, colloid, with an equal
quantity of sugar of milk and a little glycerine.
"Among the increasing literature on the employment of
colloidal metals to combat infection (puerperal fever,
peritonitis, pyaemia, acute gonorrhoea, &c.,) we find strong
testimony as to the therapeutic value of this unknown product.
The most interesting assertions come from Hocheisen, of Berlin,
(Medizinishe Klinic) who claims that while colloid silver is not
a specific, it is an invaluable aid in suitable cases.
"Colloidal silver, known also as collargol, may be made in
different ways. The most commonly used is the one known as
Carey-Lea's method which is as follows: 200 gms. of a 10 per
cent. silver nitrate solution are treated with a mixture of 200
Cc. of a 30 per cent. ferrous sulphate solution with 280 Cc. of a
40 per cent. sodium citrate solution to which has been added 50
Cc. of a 10 per cent. sodium hydroxide solution. The beautiful
lilac colored precipitate is transferred to a filter when it
becomes blue and is freed from mother liquor by exhaustion with
an air pump for half an hour. The precipitate is then washed from
the filter and dissolved in water. From a certain strength
solution in water it is precipitated by absolute alcohol.
"Intravenous Injections of Colloidal Silver in the Treatment of Erysipelas.—Warren Coleman (Medical Record, Nov. 21) has employed intravenous injection of colloidal silver with success in five recorded cases of erysipelas, but states that the number is too small to warrant any positive conclusions. Colloidal silver has been used to some extent recently with varying success in septic processes, generally pyemia, septicemia, pneumonia, anthrax, carbuncle, gonorrhea, etc. The drug is used intravenously in doses of 5 to 10 c.c. of a 1 per cent solution. The injection is made directly into one of the superficial veins at the bend of the elbow with an ordinary hypodermic syringe, the usual precautions of cleanness being observed. No reaction follows the procedure. All who have used colloidal silver agree that it is harmless. There seem to be many possibilities in its use, and its clinical application is being extended to a large degree."-- Medical Herald, Volume 23, 1904
"As discussed, the medical literature and hundreds of physicians' clinical experiences demonstrate that the natural substance silver given as an oligodynamic hydrosol can be highly effective treatment for acute and chronic infections with an exceedingly small risk of any significant toxicity for patients."-- Dr. Kent Holtorf, Holtorf Medical Group, "Safety and Efficacy of Intravenous Oligodynamic Silver"
"Colloidal Silver in Erysipelas. During the past few years
there have been several encouraging reports, principally from the
Continent, on the use of intravenous injections of colloidal
silver in various infective processes. Two requisites are
necessary to commend a drug for intravenous
administration—efficacy for its purpose, and harmlessness
in other directions. As regards the latter, everyone who has
examined the subject is agreed that no ill results occur from the
use of colloidal silver.
"The most amazing case of colloidal silver usage which I've had personal knowledge involved an 83 year old woman who was suffering severe septicemia (infectious blood poisoning). Her doctors were unable to control the raging infection and had sent her home, expecting her death in 48-72 hours. Her husband contacted an intermediary, through whom I recommended trying colloidal silver. The woman was immediately put on one tablespoon of 5 ppm colloidal silver three times daily. Within 24 hours her septicemia began to disappear, and within 48 hours her septicemic crisis was over, and she did not die as expected."-- James South, MA, Anti-Aging Bulletin, International Antiaging Systems, Vol. 4, Issue 3, Apr/May, 1999, "Hi Yo Silver, Away!"
"...it is now definitely known that the germicidal properties of certain colloidal metals are based chiefly on the fact that the metals are in the colloidal state...a vigorous growth of b. tuberculosis was killed by colloidal silver in four minutes (a solution of 1 part silver to 2,000 parts fluid). Staphylococcus pyogenes, various Streptococci, and other pathogenic organisms are all killed in three or four minutes; in fact, no microbe is known that is not killed by this colloid in laboratory experiments in six minutes...colloidal silver is quite stable even in the presence of salts and of the normal constituents of the blood. Its destructive action on toxins is very marked, so that it will protect rabbits from ten times the lethal dose of tetanus or diptheric toxin. Unlike certain organic compounds of silver, the colloidal metal does not cause necrosis of the underlying tissues...Taken internally, the particles of colloidal silver are resistant to the action of dilute acids and alkalies of the stomach and consequently...pass into the intestine unchanged. The importance of this is obvious in such conditions as ulcerative urticaria...dermatitis...dysentery, diarrhea and colitis."-- Alfred B. Searle, Use of Colloids in Health & Disease
"Nanosilver has developed as a potent antibacterial, antifungal, anti-viral and anti-inflammatory agent...The targeting of cancer cells using silver nanoparticles has proven to be effective, but neither the exact mechanism of action nor the modes of activation of the downstream signaling molecules have been revealed yet.

"Beginning in 1973, in vitro studies demonstrated that such ions were an effective antibiotic with a very broad spectrum and favorable quantitative evaluations compared with synthetic antibiotics...The failure of other nontoxic metal ions to produce a similar alteration with the same electrical parameters strongly indicates that the electrically generated silver ion is the agent responsible for the observed cellular changes...Healing rates in these wounds are significantly accelerated and are accompanied by enhanced healing of the bone, soft tissue, nerve, and skin, with replacement of missing tissues by histologically normal tissues...The responsible agent for these cellular effects is believed to be the electrically generated silver ion".-- Becker, Robert O. 2000.

"In former times, silver has already been used in a wide
variety of applications. Ancient civilizations were aware of the
bactericidal properties of silver (Hill and Pillsbury 1939).
Metallic silver was used for surgical prosthesis and splints,
fungicides, and coinage. Soluble silver compounds such as silver
salts, have been used in treating mental illness, epilepsy,
nicotine addiction, gastroenteritis, and infectious diseases,
including syphilis and gonorrhea (Marshall and Schneider 1977;

"The comeback of silver in medicine began in the 1970s. The
late Dr. Carl Moyer, chairman of Washington University's
Department of Surgery, received a grant to develop better
treatments for burn victims. Dr. Margraf, as the chief
biochemist, worked with Dr. Moyer and other surgeons to find an
antiseptic strong enough, yet safe to use over large areas of the
body. Dr. Margraf reviewed 22 antiseptic compounds and found
drawbacks in all of them.
"Silver ions are produced in enormous quantities when an
electric current is passed through silver metal in saline or
other conducting solution, including blood. The amount of current
needed is much lower than the current needed to affect the heart
muscle. Silver ions are positively charged while viruses and
bacteria have a weak negative charge. Thus, there is a mutual
attraction between the ions and the organisms, the latter being
inactivated by the ions. It seems likely that the silver ions
also attach to red blood cells and proteins in the blood, as well
as combining with chloride ions. Nevertheless, the enormous
quantity of silver ions produced appear adequate to destroy the
viral particles. The half-life of the ions in the blood is
calculated to be 7.8 seconds, giving them time to react with many
virons, particularly if the electrode is placed in a large blood
vessel, such as the superior vena cava, which empties directly
into the heart with blood from many different veins.
"...silver sulfadiazine is an antibacterial agent useful in
treating burns in man and animal. Silver sulfadiazine is also

and gonorrhea, and is spermicidal.
"As reported by the Silver Institute (a group which keeps
silver investors appraised of all of the new uses for silver in
business and industry), the EPA has recently approved the use of

schools, gymnasiums and children's activity centers.
"The catheter combines a silver electrode inserted into the
patient's blood stream with a second electrode placed on the
nearby skin. The combined action releases silver ions into the
blood for immediate reaction with pathogens such as HIV viruses.
The silver ions do not attack normal human cells because these
cells have protective walls, which is not the case for bacteria,
viruses and fungi.

microorganisms is an expanding field of research. Within this
field, an area that has been largely unexplored is the
interaction of metal nanoparticles with viruses.

"Ionic silver, although technically a colloidal, does seem to offer more beneficial properties than the traditional colloidal silver. Ionic silver can be generated by electrolyzing the silver metal or dissolving silver compounds and appears to have superior antimicrobial activity. One of the reasons for this, in addition to the charge of the particles, might be that 'silver ions in solution offer a greater surface area because of the fact that they are individual atoms, not clusters of atoms as seen in a colloid.' This means that 'they react more quickly and readily,' and since they 'are relatively smaller than colloidal particles, they will penetrate...more rapidly and effectively.'"-- Therapeutic Properties of Silver: A Historical and Technical Review, by S.M. Foran
"Silver or silver ions have long been known to possess strong inhibitory and bactericidal effects as well as a broad spectrum of antimicrobial activities. Several propositions have been developed to explain the inhibitory effects of silver ion/silver metal on bacteria. It is generally believed that heavy metals react with proteins by combining the thiol (– SH) groups, which leads to the inactivation of the proteins. Recent microbiological and chemical experiments have revealed that the interaction of silver ions with thiol groups plays an essential role in bacterial inactivation."-- Digest Journal of Nanomaterials and Biostructures, Vol. 6, No 1, January-March 2011, p. 149 - 154, Antimicrobial Activity Of Colloidal Silver Nanoparticles Prepared By Sol-Gel Method
"Silver cations (Ag+) are microcidal at low concentrations and used to treat burns, wounds and ulcers. Ag is used to coat catheters to retard microbial biofilm development. Ag is used in hygiene products including face creams, "alternative medicine" health supplements, supermarket products for washing vegetables, and water filtration cartridges. Ag is generally without adverse effects for humans, and argyria (irreversible discoloration of the skin resulting from subepithelial silver deposits) is rare and mostly of cosmetic concern."-- S.

"Speaking generally, the colloidal metals are especially remarkable for their inhibitive action in infective states— septicaemia and pyaemia. This action has been shown to be due to their stimulating influence on phagocytosis and to their destructive effects on micro-organisms and their toxins as shown by the immediate fall of temperature and the subsidence of the constitutional symptoms of intoxication.
Similarly, the colloid products can be injected, in accordance with the indications, into the spinal canal (cerebro-spioal meningitis) and the serous cavities (pleurisy, timpytma, in.) or applied locally to the surface of diseased mucous membranes. Their introduction into the circulation is followed in a few hours by a sharp febrile reaction for which we must be prepared, but which soon gives place to a marked and durable fall of temperature associated with remission of the general and local symptoms.
The colloidal metals have been extensively employed in acute inflammatory infections of the lungs (pneumonia and broncho-pneumonia) and pleura (pleurisy and empyema). The injection is followed by a marked change in the opsonic index (positive) and the crisis in pneumonia is notably precipitated. It is indeed in the treatment of inflammatory affections of the lung and pleura (and in puerperal fever, vide infra) that the electric colloids have yielded the most brilliant results.
In addition to the intravenous or intramuscular injections, eleotrargol has been introduced into the pleural cavity in presence of pleurisy and empyema, apparently with much benefit. In puerperal septicaemia (puerperal fever) and peritonitis whether consecutive to labour or as the result of appendicitis the most remarkable effects follow the intravenous injection of these colloids; Indeed, in some instances the patients have been rescued from apparently inevitable death.
Even more interesting are the results obtained in acute meningitis and in epidemic cerebrospinal meningitis. In the latter electrargol can be employed either alone or in conjunction with the serum treatment. The injection is usually intravenous, but in severe cases it should be made directly into the spinal canal so as to obtain immediate effects. It will be seen that the action of the metallic colloids it not limited to any particular variety of microbial infection, but extends to most.
A glance at the bibliographical notes will show that these remarkable results have not been obtained by any one observer or group of observers, nor in any one country. They are daily being placed on record in medical literature all over the world. In view of their daily increasing field of usefulness it can hardly be doubted that a new and interesting chapter has been opened up in contemporary therapeutics by the introduction of the colloid metal.
One point stands out prominently, and that is the absolute innocuousness of these bodies, whether injected into the veins or muscles or into the spinal canal. Injected into muscle they cause very little local reaction or pain, and the dose is determined solely by the requirements of the case since they are devoid of toxicity."*-- The Lancet, February 3, 1919
[*Editor's note: Never use colloidal silver intravenously except under a doctor's direction and supervision. In spite of what this older article says, there have been some deaths recorded in early medical literature from the use of intravenous colloidal silver. Additionally, colloidal silver for intravenous use must be prepared as an isotonic solution to avoid the lysing of red blood cells.]
"Many doctors, scientists, and now news men, have as of late, been claiming that silver is a problem because it is a heavy metal, and as such can poison the body. The problem is not with the silver but with the misinformed and inadequate knowledge of the people speaking about things they know little about. The real answer is that silver is not toxic when used at reasonable levels and quantities! Any substance, even water, in excessive amounts can be fatal. Toxic nephropathy or heavy metal poisoning is defined as, "Any functional or morphologic change in the kidney produced by an ingested, injected, inhaled, or absorbed drug, chemical, or biological agent."
The MERCK Manual is sometimes referred to as the "Scientific Bible Of Diagnosis And Therapy" by many scientists and doctors. Silver is the only heavy metal not listed in the manual for causing heavy metal poisoning, because it does not cause it. (See MERCK manual (17th Edition, Pg 1880, table 226-1, third item listed, for the full list of heavy metals that cause toxic nephropathy).
In a recent peer - review paper ,"Ultradilute Ag-Aquasols with extraordinary bactericidal properties: the role of the system Ag-O-H2O", (Materials Research Innovations, vol. 11, no. 1, (2007) pages 3-18) on the subject of the safety of consuming metallic silver, the paper states (page 1, first paragraph of the introduction), "A recent paper by Das et al. Provides the remarkable datum that some 275,000 kg [(605,000 pounds)] of edible metallic silver foil are consumed every year (in food) in India. No known adverse health effects have ever been recorded. This epidemiological evidence that silver as a metal is not toxic in any way needs no further comment. Further support for the obvious safety of consuming metallic silver (Ag0) is in the worldwide consumption of (so called) silver colloids, often made at home in primitive electrochemical cells by probably some millions of citizens, again with no ill effects."
It is estimated that the Indian tradition of eating candy and cakes wrapped in metallic silver foil (eaten foil and all) came from their historically gained knowledge that in their warm, moist climate with little refrigeration of foods, eating the silver-covered candy and cakes after meals would kill the bacteria consumed with the food, before it had a chance to do damage to their body systems. In other words, the people of India have proven over the last thousand years that eating or consuming large amounts of metallic silver has no negative effect on the body or body systems."-- Keith Moeller, The Safety of Using Silver Solutions and the Risk of Argyria, American Biotech Labs, January 15th, 2008

Unique qualities of silver ions are: Low risk for bacteria resistance, effective in very low concentrations, no human toxicity."-- Dr. Murray J. Height, Ph.D, Chief Technology Officer, HeiQ Materials, Silver Nanotechnology Working Group
"It is the silver ion (Ag+) that provides silver with its unique recognition as the healthful metal. Its bactericidal activity is unique because though this ion breeches walls of bacterial cells, it does not do so to mammalian cells. This selectivity, which remains unclear, was perceived during ancient times leading to its universal use."-- Samuel F. Etris, The Silver Institute, writing in Silver Compounds
"It has been suggested that the number of pathogens killed relates directly to the number of silver ions present...The research data confirmed that it is not the total amount of silver in suspension, but the total amount of ionized silver in solution, that determines effectiveness."-- Environmental Health Foundation, Silver for Human Health
"In one case, Dr. Robert O. Becker, M.D., was astonished when he attempted to use electrically generated silver ions to heal the infection in a patient's horrifically infected leg bone and tissue wound. He had expected the infected bone to recede as the microbes were killed by the electrically generated silver ions.
Instead, he discovered that not only were all of the pathogens killed, but new tissue and new bone began to grow in, creating a strong union in the bone where previously there had been none. As Dr. Becker later recounted:
'...I debrided the wound, removing the dead tissue and all grossly infected or dead bone. There wasn't much left afterward. It was an enormous excavation running almost from his knee to his ankle. In the operating room we soaked a big piece of silver nylon in saline solution and laid it over the wound...wrapped the leg, and connected the battery unit. By the end of the week...all of our bacterial cultures were sterile.
The soft healing tissue, called granulation tissue, was spreading out and covering the bone. In two weeks, the whole base of the wound, which had over eight square inches of raw bone, was covered by this friendly pink carpet. The skin was beginning to grow in too, so we could forget about the grafts we thought we'd need to do...
...I decided to take an X-ray to see how much bone he'd lost...I could hardly believe the picture. There was clearly some bone re-growth! I removed the cast, felt the leg, and found that the pieces were all stuck together. The patient watched, and when I was done he lifted his leg into the air triumphantly. I'd never so much enjoyed being wrong.'"-- Colloidal Silver Secrets Ezine, July 2011, "Can Colloidal Silver Help Re-Mineralize Damaged Tooth Enamel?"
"Silver nanomaterials are fine particles of metallic silver that have at least one dimension less than 100 nm. Nanosilver is not a new discovery; it has been known for over 100 years (USFDA, 2010). Previously, nanosilver or suspensions of nanosilver were referred to as colloidal silver. To produce colloidal silver, a positive electrical current is applied through pure silver bars suspended in water resulting in colloidal silver particles with a size range of 15-500 nm (Lindemann, 1997). Before the invention of penicillin in 1928, colloidal silver had been used to treat many infections and illnesses (Nano Health Solutions, 2010). By converting bulk silver into nanosized silver, its effectiveness for controlling bacteria and viruses was increased multifold, primarily because of the nanomaterials' extremely large surface area when compared to bulk silver, thus resulting in increased contact with bacteria and fungi. Nanosilver, when in contact with bacteria and fungus, adversely affects the cellular metabolism of the electron transfer systems, and the transport of substrate in the microbial cell membrane. Nanosilver also inhibits multiplication and growth of those bacteria and fungi which caused infection, odor, itchiness and sores (Nanotech Plc, 2010)."-- U.S. Environmental Protection Agency, Scientific, Technical, Research, Engineering and Modeling Support Final Report: State of the Science Literature Review: Everything Nanosilver and More, August 2010

"Scientists have discovered that the body's most important fluids are colloidal in nature: suspended ultra-fine particles. Blood, for example, carries nutrition and oxygen to the body cells. This led to studies with colloidal silver (electrical silver atoms). An electro-colloidal process, which is known to be the best method, is used for manufacturing the Colloidal silver. Colloidal silver appears to be a powerful, natural antibiotic and preventative against infections. Acting as a catalyst, it reportedly disables the enzyme that one-celled bacteria, viruses and fungi need for their oxygen metabolism. They suffocate without corresponding harm occurring to human enzymes or parts of the human body chemistry. The result is the destruction of disease-causing organisms in the body and in the food."-- Nanotechnology In Medicine And Antibacterial Effect Of Silver Nanoparticles, Digest Journal of Nanomaterials and Biostructures Vol. 3, No.3, September 2008, p. 115 - 122
"Colloidal silver affects single-celled microorganisms as long as it physically touches them. Therefore, even though colloidal silver cannot disable pathogens in solids such as bone and feces, it can easily disarm them in liquids such as water, blood, urine and lymph. If you take colloidal silver on an empty stomach, it will directly contact any Helicobacter pylori that's present (H. pylori is responsible for ulcers and stomach cancer). And colloidal silver traveling directly to a relatively empty gut, with no stool to block its passage, can kill unwanted microorganisms there that cause food poisoning and dysentery. (Similarly, in the laboratory, silver cannot affect microbes in a solid, gel-like nutrient agar, but it will affect microbes in a nutrient broth.)"-- Nenah Sylver, PhD, The Rife Handbook – Chapter 3 excerpt, "Colloidal Silver"
"The results of our laboratory testing show that the infection fighting properties of silver is quite effective in killing the MRSA strain. Used in medical dressings or in ointment form, silver can be an extremely useful first defense in stopping MRSA before it develops into a systemic infection. Moreover, due to the nature of antimicrobial silver, it is highly unlikely that MRSA or other developing strains of staph infections will ever build immunities to silver as they have to penicillin and some topical antibiotics...With the recent spread of MRSA, people must take special precautions and doctors need to consider antibiotic-resistant strains when treating infections. By washing and applying a long-lasting silver antimicrobial product to scrapes and cuts, people can stop MRSA before they become serious infections."-- "Topical Silver An Effective Defense Against MRSA Threat," Bruce Gibbins, founder and CTO of AcryMed, July 14, 2005
"The Antiviral Effect of AgNPs (Silver Nanoparticles) as a Topical Agent on Human Cervical Tissue -- In an experiment evaluating AgNPs application on Human cervical tissue as an anti-HIV-1 agent, Lara and colleagues found that AgNPs provided protection against the transmission of cell-free and cell-associated HIV-1. They had used an excellent human cervical tissue culture model to elucidate anti-HIV-1 activity of AgNPs within one minute after the topical treatment on the human cervical tissue. The similar effect was found for 20 minutes time point of topical pretreatment and washing of the AgNPs. The human cervical tissue culture remained protected against infection with HIV-1 for as long as 48 h, demonstrating a long-lasting tissue protection afforded by AgNPs. This lasting protection is necessary for a topical vaginal microbicide to ensure safety against infection even for many hours after gel application and, even more importantly, after the gel is washed away."-- Journal of Nanobiotechnology, September 2011, "Silver nanoparticles are broad-spectrum bactericidal and virucidal compounds," Humberto H Lara, Elsa N Garza-Treviño, Liliana Ixtepan-Turrent and Dinesh K Singh
"Often called the 'penicillin of alternative medicine,' colloidal silver (CS) disables the enzymes that bacteria, parasites, viruses, and fungi rely on to use oxygen. Unable to 'breathe,' the organisms die and are eliminated from the body. While an antibiotic drug may kill several types of disease organisms, CS delivers the kiss of death to at least 650 disease organisms. In addition, CS can be taken over long periods of time because microorganisms cannot develop a resistance to it.
CS may sound like something very high-tech, but it has been used for several thousand years. In ancient Greece and Rome, people stored water and wine in silver urns to retard the growth of bacteria. During the bubonic plague in Europe, children of wealthy families sucked on silver spoons to preserve their health-thus the phrase, "Born with a silver spoon in your mouth."
During the days of the American frontier, pioneer families put silver dollars in fresh milk to keep it from spoiling. Until the late 1930s, when convenient, inexpensive antibiotic drugs were introduced, silver-based products were the most commonly used antimicrobials. More than four-dozen were marketed in the United States at that time. However, when penicillin and other drugs came into widespread use, silver-based products all but disappeared. Two holdovers are the silver nitrate eye drops given to newborns to prevent infection and the silver-based ointments used to treat severe burns.
ROLE FOR ANTI-AGING:
Among the conditions CS has controlled are severe burns, acne, boils, candida and yeast infections, chronic fatigue syndrome, digestive problems and colitis, ear and sinus infections, herpes, shingles, lupus, malaria, viral and fungal infections, blood parasites, rheumatoid arthritis, and ringworm. CS also has been effective in treating cancer and AIDS if used at certain point in the disease cycle when infected cells have reverted to a more primitive way of using oxygen, however these uses of CS are not clinically proven.
Clinical research has uncovered no adverse effects from properly prepared colloidal silver, nor have there been any reported cases of CS-drug interaction. Do not use CS for prolonged periods of time (more than seven consecutive days). Note: In February 1997, the U.S. FDA issued the following statement: The use of colloidal silver-containing products constitutes a potentially serious public health concern ... the consumption of silver by humans may result in argyria - a permanent ashen-gray or blue discoloration of the skin, conjunctiva [eye], and internal organs... Colloidal silver-containing products have never been approved by the FDA for treatment of animal disease in any animal species.
The recommended dosage of CS depends upon the concentration of the product you are using, which is expressed as "ppm" or "parts per million." Concentrations range from 5ppm to 500ppm. In general, the greater the ppm the larger the CS particle size. This variable is important because it takes a smaller particle size to kill a virus vs. bacteria. Some companies have developed technology that allows increased ppm while preserving a smaller particle size. CS can be taken internally in a small amount of distilled drinking water. It also can be applied topically to cuts and open sores and can be inhaled or sprayed using an atomizer."-- The American Academy of Anti-Aging Medicine, Physician & Practitioner Administered Procedures and Therapies, http://www.worldhealth.net/news/colloidal_silver
"Silver is known to exhibit a broad spectrum of biocidal activity towards many bacteria, fungi and viruses. Silver, in its uncharged state (that is, AgNPs) is also found to possess antimicrobial properties. Although the mechanism of this action is still unresolved, it has been shown that AgNPs interact with the constituents of the outer membrane of bacteria, causing structural changes and degradation that eventually lead to the death of the bacterial cells. AgNPs that are less than 15nm in size are known to have efficient antibacterial activity."-- Nature Materials Journal, 20 January 2008; doi:10.1038/nmat2099, "Silver-nanoparticle-embedded antimicrobial paints based on vegetable oil,"

"Critics of colloidal silver sometimes state that it has been known to cause organ damage, kidney damage, pulmonary edema, atherosclerosis and death....These claims appear to be based on a research study on dogs in which the dogs were deliberately killed by extremely large lethal doses of silver. At the doses given, any heavy metal and probably many essential minerals like zinc, iron, copper, etc. would have produced death in similar fashion...We know that dogs died from injections of a type of protein-bound silver in dosages ranging from 500 mg to 1.9 grams of silver depending on the frequency of administration. This was equivalent in silver content to giving [per day] a 150 pound adult between 150 litres and 570 litres of 10 ppm colloidal silver, or between 75 and 285 liters of 20 ppm colloidal silver or between 50 and 190 litres of 30 ppm colloidal silver. The 10 gram estimated lethal dose for humans from Goodman and Gillman is equivalent to 1000 liters of 10 ppm colloidal silver."-- Dr John Hill D.C., "Colloidal Silver, A Literature Review"
"...you should be advised that we recently completed an extensive review of the scientific literature on the safety of silver, especially as it relates to its one known potential side effect, namely, Argyria. Argyia is an irreversible discoloration of the pigment (skin) caused by excessive silver intake or chronic exposure to silver by certain tissues. The amount of silver required to develop Argyria is estimated [by the EPA] to be 3.8 grams per day. By comparison standard 10 ppm colloidal silver contains silver in amounts equaling less than 1 milligram of silver (1,000 micrograms = 1 milligram; 1,000 milligrams - 1 gram), which therefore represents an amount approximately 1/500th to 1/1000th of the amount of silver considered to be a risk in the development of Argyria.
"Most cases of Argyria reported in the medical literature over the last 100 years involved chronic intravenous or intramuscular use of the silver preparations, most often involving a silver drug prescribed by physicians which in most cases contained silver nitrate. Other cases of Argyria reported in the medical literature involve application of silver preparations used for many months or years in the treatment of the eye or vagina for certain diseases. We could not locate a single case of orally consumed colloidal silver manufactured in the last 25 years causing Argyria in our review of the literature. This is probably due to the low levels of silver contained in such preparations, since only very small amounts of silver are needed for its antiseptic effect.
"Humans consume approximately 100 micrograms of silver every day in the diet. Additional amounts within this range would be considered safe by all reasonable estimates, especially if the amount needed to develop Argyria would be the equivalent of 380,000 micrograms (or 3.8 grams) of silver a day.
"As for the efficacy of silver preparations, we found considerable scientific evidence published over the last 75 years that a number of silver compounds can be effective germicidal (antiseptic) agents against several hundred pathogenic organisms. However, silver is not termed an antibiotic as some have claimed because an antibiotic by definition is derived from a living organism.-- Alexander G.

"While silver and its compounds have been medically used for thousands of years, the recent research focus on this element has led to a resurgence in interest, particularly in the field of wound care product development. The increasing problems of antibiotic resistance, combined with concerns over the safety and toxicity of topical antiseptics, has highlighted the need for a safe agent which can be used to treat colonized and infected wounds effectively. Wounds, notably chronic wounds, can support a wide variety of microorganisms, many of which are pathogens, and act as a source for cross-infection. While systemic antibiotics are justifiably recognized as the first-line treatment of choice for chronic wounds with spreading cellulitis and infected wounds in 'at risk' patients, not all infected wounds merit this treatment. There is now a rationale for the judicious use of suitable topical antisepsis in certain colonized, critically colonized, and infected wounds. The increasing evidence available on products containing silver suggests that this element can fulfil a valuable role in wound care. This review of the history of silver as an antibacterial covers the mode of action of preparations containing silver and concludes with a focus on silver as a component of the modern wound management products: Arglaes, Acticoat, Actisorb Silver 220 and Avance."-- Richard J White British Journal of Community Nursing, Vol. 6, Iss. 8 (Silver Suppl 1), 03 Aug 2001, pp 3-8
"A. Bart Flick, MD, practicing medicine at Mountain Medical Specialties, Dernorest, Georgia, USA, uses silver ion therapy on cases of severe trauma. Loss of skin from hands and fingers presents a most difficult problem because the skin is thick and has a different sensory response from skin from other parts of the body. Thus skin grafted on hands and fingers from other parts of the body results in unsatisfactory function and is without normal sensation because nerves are not regenerated in grafted skin. However, the use of the silver technique results in the rapid regeneration of normal, full thickness, flexible skin of the type removed by the injury. The skin is regenerated in all of its complex tissue morphology even including a fingerprint."-- The Development and Functions of Silver in Water Purification and Disease Control, by Richard L. Davies and Samuel F. Etris. The Silver Institute, Washington DC.
"Over the past several decades, silver has been used in medicine in treating burns and for eye, ear, nose and throat, urethra and vaginal inflammation and infection. Silver needles are commonly used in acupuncture. Silver ions have been used to treat cystitis and urinary tract infections in children. Silver salts have proved effective for warts. A silver compound know as silver sulfadiazine has been used in 70% of burn centers in the USA.
Silver has been prescribed in Anthroposophical medicine, particularly as an aid to the brain, reproductive disorders in women, the circulatory system and as a disinfectant. It is also used as a remedy for mental imbalances, sleepwalking and anorexia nervosa.
In Homeopathy, (which the FDA and AMA tried with a vengeance to destroy throughout the 20th century) silver is used for headaches, chronic hoarseness, neuralgic pain in the joints, congestion of the windpipe, brain and sinus problems, and loss of control and balance."-- The Association For Advanced Colloid Research, 1994
"Silver has been used for at least six millennia in order to prevent microbial infections. It has been used to treat a wide variety of infections and has been effective against almost all organisms tested. Silver compounds were major weapons against wound infection in World War I until the advent of antibiotics and between 1900 and 1940, tens of thousands of patients consumed colloidal silver, and several million of doses were given intravenously...
...The mechanisms of action and binding of silver nanoparticles to microbes remain unclear but it is known that silver binds to the bacterial cell wall and cell membrane and inhibits the respiration process (Klasen, 2000) by which the chemical energy of molecules is released and partially captured in the form of ATP. Silver nanoparticles interact with sulfur-containing proteins of the bacterial membrane as well as with the phosphorus containing compounds like DNA to inhibit replication (Silver et al., 2006). Bactericidal effect of silver has also been attributed to inactivation of the enzyme phosphomannose isomerase (Bhattacharya & Mukherjee, 2008), that catalyzes the conversion of mannose-6-phosphate to fructose-6-phosphate which is an important intermediate of glycolysis, the most common pathway in bacteria for sugar catabolism.
The antimicrobial activity of silver nanoparticles has been investigated against yeast, gram negative and positive bacteria (Kim et al., 2007) (Sondi & Salopek-Sondi, 2004; Yu, 2007)...
...Recently, due to the emergence of antibiotic-resistant bacteria and the use limitations of antibiotics that can cause serious diseases and is an important public health problem (Furuya & Lowy, 2006), the synergetic effect of silver nanoparticles with antibiotics has been studied combining silver nanoparticles with different antibiotics like ampicillin, kanamycin, erythromycin and chloramphenicol against gram positive and gram negative bacteria. The antibacterial activities of these antibiotics increase in the presence of silver nanoparticles against gram positive and gram negative bacteria determined by the disk diffusion method. Different diameters of inhibition zones have been shown around the different antibiotic disk with or without AgNPs.
The combination effect of nanosilver and ampicillin has more potential compared to the other antibiotics and may be caused by both, the cell wall lysis action of the ampicillin and the DNA binding action of the silver nanoparticles (Fayaz et al., 2009). The antibiotic molecules contain many active groups such as hydroxyl and amido groups, which reacts easily with silver nanoparticles by chelation, for this reason, the synergistic effect may be caused by the bonding reaction with antibiotic and silver nanoparticles."-- Silver Nanoparticles Interactions with the Immune System: Implications for Health and Disease, CABIMER-Andalusian Center for Molecular Biology & Regenerative Medicine CSIC-University of Seville-UPO-Junta de Andalucia, Seville, Spain 2 Department of Physical, Chemical & Natural Systems, Pablo de Olavide University, Seville, Spain
"Silver has been used for centuries to prevent and treat a variety of diseases including pleurodesis, cauterisation, and healing of skin wounds. Its antibacterial effect may be due to blockage of the respiratory enzyme pathways and alteration of microbial DNA and the cell wall. In addition to its recognized antibacterial properties, some authors have reported on the possible pro-healing properties of silver. The use of silver in the past has been restrained by the need to produce silver as a compound, thereby increasing the potential side effects. Nanotechnology has provided a way of producing pure silver nanoparticles. This system also markedly increases the rate of silver ion release. Recently, we demonstrated that silver nanoparticles exhibit cytoprotective activities toward HIV-1-infected cells. Published studies of silver nanoparticles on wound healing are sparse, and the mechanism of action remains unknown. Herein we report that silver nanoparticles can promote wound healing and reduce scar appearance in a dose-dependent manner. Furthermore, our studies show that silver nanoparticles act by decreasing inflammation through cytokine modulation. The potential benefits of silver nanoparticles in all wounds can therefore be enormous."-- Topical Delivery of Silver Nanoparticles Promotes Wound Healing, ChemMedChem 2007, 2, 129 – 136, K. K. Y.

"Scientists have discovered that the body's most important fluids are colloidal in nature: suspended ultra-fine particles. Blood, for example, carries nutrition and oxygen to the body cells. This led to studies with colloidal silver (electrical silver atoms). An electro-colloidal process, which is known to be the best method, is used for manufacturing the Colloidal silver. Colloidal silver appears to be a powerful, natural antibiotic and preventative against infections. Acting as a catalyst, it reportedly disables the enzyme that one-celled bacteria, viruses and fungi need for their oxygen metabolism. They suffocate without corresponding harm occurring to human enzymes or parts of the human body chemistry.

"Metallic silver is relatively unreactive however, when exposed to aqueous environments some ionic silver (Ag+) is released...the principle activity of silver is as a result of the production of silver ions within an aqueous matrix. This therefore implies that for silver to have an antimicrobial effect, free water must be present... Silver ions clearly do not possess a single mode of action. They interact with a wide range of molecular processes within microorganisms resulting in a range of effects from inhibition of growth, loss of infectivity to cell death. The mechanism depends on both the concentration of silver ions present and the sensitivity of the microbial species to silver. Contact time, temperature, pH and the presence of free water all impact on both the rate and extent of antimicrobial activity. However, the spectrum of activity is very wide and the development of resistance relatively low, especially in clinical situations."-- Technical White Paper: Antimicrobial Activity of Silver V1.0 - September 2005, Industrial Microbiological Services, LTD
"Silver can exist in 'elemental' or 'ionic' form. Silver ions are also referred to as 'Ag+' or 'silver cations'. All silver-containing products, whether elemental or ionic, achieve their antimicrobial effect via the action of silver cations.
Elemental silver exists as a neutral atom and is relatively unreactive. In the presence of oxygen, elemental silver oxidizes to form silver oxide, and upon dissolution in fluid (such as wound exudate), silver oxide dissociates into separate components releasing antimicrobial silver cations.
Ionic silver is positively charged and has antimicrobial activity. The broad-spectrum antimicrobial activity of silver is thought to be attributed to the silver cations interfering with electron transfer and binding to the following negatively charged moieties in the target cell: Cell wall, cell membrane, DNA."-- Systagenix Wound Management 2011, January 2011 Edition, Silver White Paper, Everything You Ever Wanted to Know About the Use of Silver in Wound Therapy, Sharon Lindsay, Systagenix

"Prior to 1938, colloidal silver was widely used to prevent or treat numerous diseases. Its use decreased with the development of antibiotics, such as penicillin and sulfanilamide. However, since 1990 there has been a resurgence on the use of colloidal silver as an alternative medicine because of increased resistance of bacteria to antibiotics, and the continuing search for novel and affordable antimicrobial agents. Colloidal silver is a suspension of submicroscopic metallic silver particles of about 0.001 microns in size, the presence of particles results in the overall increased surface area. Colloidal silver has been used as disinfectant of foods and water in Mexico; it acts by disabling the oxygen metabolism enzymes in bacteria, which ultimately kills microorganisms. In vitro evidence has shown that bacterial isolates of Escherichia coli and Staphylococcus aureus are highly susceptible to colloidal silver treatment...The overall results [of our study] indicated that the colloidal silver has antitumor activity through induction of apoptosis in MCF-7 breast cancer cell line, suggesting that colloidal silver might be a potential alternative agent for human breast cancer therapy."-- Antitumor Activity of Colloidal Silver on MCF-7 Human Breast Cancer Cells, Journal of Experimental & Clinical Cancer Research 2010, 29:148

"Silver has very powerful antibacterial, antifungal and antiviral properties and can be used for all types of gram positive and gram negative bacteria. Its role in controlling the deadly necrotizing fasciitis, MRSA and other infections is of paramount importance today. Pathogens do not develop resistance to silver and therefore it is very effective...Silver can also be used for disinfecting ORs / OTs in hospitals and areas where pharmaceutical / food preparations are being made, to keep the bacterial count to very low levels. Silver being a nutritional supplement and a natural antibiotic, it is one of the safest in the long run...Silver particles around 200 nanometer are able to kill microorganisms - bacteria and fungi which affect skin and hair. For viral infections you need to go below 200 nanometer in size. So colloidal silver is effective inside the body and the mg doses are small enough not to be of any toxic consequences....Typically for human consumption 3 ppm silver solution is fine. This means there is 0.75 mg in a 250 mL / 8.0 oz. glass of silver solution. This dose is roughly 10% of the amount one consumes in a single piece of barfi. This dose is good for oral use to fight gram positive and gram negative bacterial and fungal infections of all types...Typical dose required for topical applications either by way of gel or spray is 30 ppm. In case of very high bacterial load one can safely go up to 100 ppm."--Pramod Vora, Anti-Aging & Regenerative Medicine Practitioner, Director, SpaceAge Health Center, Silver: A Powerful Antibiotic

"The major mechanism through which silver nanoparticles manifested antibacterial properties is by anchoring to and penetrating the bacterial cell wall, and modulating cellular signalling by dephosphorylating putative key peptide substrates on tyrosine residues. Silver nanoparticles act primarily in three ways against Gram-negative bacteria: (1) nanoparticles mainly in the range of 1–10 nm attach to the surface of the cell membrane and drastically disturb its proper function, like permeability and respiration; (2) they are able to penetrate inside the bacteria and cause further damage by possibly interacting with sulfur- and phosphorus-containing compounds such as DNA; (3) nanoparticles release silver ions, which have an additional contribution to the bactericidal effect of the silver nanoparticles. Although bacterial cell lysis could be one of the reasons for the observed antibacterial property, nanoparticles also modulate the phosphotyrosine profile of putative bacterial peptides, which could thus affect bacterial signal transduction and inhibit the growth of the organisms. The effect is dose dependent and is more pronounced against gram negative organisms than gram-positive ones. The antibacterial effect of nanoparticles is independent of acquisition of resistance by the bacteria against antibiotics."-- Nanotechnology in Medicine and Antibacterial Effect of Silver Nanoparticles, Department of Medicine, Institute of Medical Sciences, Banaras Hindu University, Varanasi, India, published in the Digest Journal of Nanomaterials and Biostructures Vol. 3, No.3, September 2008, p. 115-122
"Although silver has been used for thousands of years as an antimicrobial agent, during the last century there have been a number of suspicions raised about its effectiveness and safety.

"In order for silver to have any antimicrobial properties, it must be in its ionized form (Lok et al., 2007; Rai et al., 2009). Silver in its non-ionized form is inert (Guggenbichler et al., 1999), but contact with moisture leads to the release of silver ions (Radheshkumar and Munstedt, 2005). Thus, all forms of silver or silver containing compounds with observed antimicrobial properties are in one way or another sources of silver ions (Ag+); these silver ions may be incorporated into the substance and released slowly with time as with silver sulfadiazine, or the silver ions can come from ionizing the surface of a solid piece of silver as with silver nanoparticles."-- Microbe Wiki, Silver As An Antimicrobial Agent

Three different types of nano-silver liquid were tested in several different concentrations on three types of media to assess their antifungal activities. Results from n vitro experiments showed that all three of the nano-silver liquids had more than 90% inhibition rates at a concentration of 7 ppm. Greenhouse experiments revealed that all of the nano-silver liquids increased biomass and dry weights, and there were minimal changes in the population of various bacteria and fungi from the soil of greenhouse-cultivated green onions. In addition, a soil chemical analysis showed that there were minimal changes in soil composition...Nano-silver liquid for the prevention of various plant pathogenic fungi is highly recommended to farmers. Additionally, the use of nano-silver does not cause any harm to human beings, and it is safe for the environment and agricultural products. In conclusion, we can say that by using nano-silver liquid, environmental pollution and the excessive use of chemical compounds in the field can be reduced. It is expected that the application of nano-silver at low concentrations will be economic, eco friendly, and decrease farm management costs."-- Mycobiology, 2010 March; 38(1): 39–45; "The Effect of Nano-Silver Liquid against the White Rot of the Green Onion Caused by Sclerotium cepivorum"
"The use of silver in medicine is as old as western medicine itself. Hippocrates is known to have used it to treat ulcers and wounds, the Romans almost certainly knew of its healing properties, its use continued through the middle ages and up to the present day. In the antibiotic age, interest in silver may have waned a little. But with urgent need to fight antibiotic-resistant bacteria, there is resurgence in its uses... A paper published today in the journal Science Translational Medicine sheds some light on silver's success against bacteria. The most important finding is that silver—unlike most antibiotics—works in more than one way. This is perhaps why bacteria may find it difficult to build resistance to the chemical. Here is silver's multi-pronged approach: first, silver sticks very strongly to sulfur, found in parts of proteins. These sulfur groups normally bond to each other, holding proteins together and keeping the protein folded up in its correct shape. But if silver interacts with sulfur, then the protein cannot fold correctly, and thus it cannot do its job. Next, silver interferes with how bacteria use iron. Iron is often held in place within proteins by binding to sulfur. Since silver also interacts with sulfur, it blocks the iron from doing so. Finally, silver causes bacteria to produce extremely toxic substances called reactive oxygen species. These go on to cause damage inside the cell, harming the DNA, proteins, and even the membrane that surround cells. The net result of this silver onslaught is bacteria with severe damage to their basic biochemistry. In addition, the membranes and walls that surround the bacteria are leakier after the silver treatment."-- Mark Lorch, ARS Technica, Senior Lecturer in Biological Chemistry at University of Hull, UK
"The antimicrobial affect of SDS-CS [Spark Discharge System Colloidal Silver] on Staphylococcus aureus was studied. The results show that CS solutions with an ionic silver concentration of 30 ppm or higher are strong enough to destroy S. aureus. In addition, it was found that a solution's antimicrobial potency is directly related to its level of silver ion concentration."

"I find it rather fascinating that the alarm bells of regulatory authorities scare consumers into believing that if they take colloidal silver it is dangerous and their skin will turn gray. There are a few case reports in the literature of argyria occurring from colloidal silver use. In one case a lady consumed 1 liter a day for over a year4 and then had a problem. In another case, it was use of the cheap home-made electrically-produced colloidal silver that was the problem. And in another case it was regular consumption of colloidal silver for over a year. Problems are rare considering all the people using colloidal silver. The common thread is cheap silver products used in high amounts for extended periods of time."-- Byron J. Richards, CCN (Board Certified Clinical Nutritionist, charter member of the International & American Association of Clinical Nutritionists (IAACN), author Fight for Your Health: Exposing the FDA's Betrayal of America)
“…an inert lump of silver isn’t going to do much. To be effective, it must first ionize. Research has shown that it’s silver in its ionic (Ag+) and not elemental form that is antibacterial.
An atom of silver has a neutral charge; we need to ionize it – take away a negatively charged electron – to transform it into its positively charged ionic form. Silver-based antibacterial surfaces must release silver ions directly into the pathogenic environment to be effective.”

“The antimicrobial activity of the silver ions was first identified in the 19th century, and colloidal silver was accepted by the US Food and Drug Administration (FDA) as being effective for wound management in the 1920s. However, after the introduction of penicillin in the 1940s, antibiotics became the standard treatment for bacterial infections and the use of silver diminished…
….To date, there are less than 20 published reports of silver resistance in bacteria and only a few of these include data that help clarify resistance mechanisms. McHugh et al. described the first instance when a silver-resistant strain of Salmonella typhimurium emerged in a hospital burns unit…
…Issues related to silver product testing include a failure to establish standard procedures for determining MIC values, an absence of recognized breakpoints, a lack of conformity in the way different products release silver and variations in the effects of microbiological media on silver release and the measurement of inhibitory activity…Despite these difficulties, there have been fewer than 20 documented reports of bacterial resistance to silver since 1975….High-level, single-step, target-based mutation to silver resistance is unlikely because of the multifaceted mode of action of the silver ion…
…The increased use of silver dressings has occurred because alternatives are required to replace antibiotics in the management of infected wounds. Until more clarity is available concerning MIC levels and breakpoints relating to silver, clinicians should take the common sense measure of using silver dressings that are effective against both Gram-positive and Gram-negative bacteria, with a proven high degree of silver ion release and rapid bactericidal activity.
Some of the higher silver release formulations produce ionic silver concentrations that reach 70–100 parts per million when measured in ionic water and kill relevant bacteria within 30 min. They also provide a continuous supply of new ionized silver molecules. There is also evidence to support their efficacy in the clinical environment…
…Some silver-based dressings appear to provide an effective alternative to antibiotics in the management of wound infection. However, dressings that release low levels of silver ions are likely to be more problematic in terms of selection for resistance, especially if the silver concentration is sub-lethal. In order to minimize the risk of silver resistance, clinicians should choose dressings that release high levels of silver ions and that demonstrate rapid bactericidal activity.”

“In metallic (elemental) form, silver is unreactive and cannot kill bacteria. To become bactericidal, silver atoms (denoted as Ag or Ag0) must lose an electron and become positively charged silver ions (Ag+ ).
Elemental silver ionises in air, but ionises more readily when exposed to an aqueous environment such as wound exudates.
…Silver ions are highly reactive and affect multiple sites within bacterial cells, ultimately causing bacterial cell death. They bind to bacterial cell membranes, causing disruption of the bacterial cell wall and cell leakage.
Silver ions transported into the cell disrupt cell function by binding to proteins and interfering with energy production, enzyme function and cell replication.
Silver ions are active against a broad range of bacteria, fungi and viruses, including many antibiotic-resistant bacteria, such as meticillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococci (VRE).”

“In the field of medicine, silver stands out like a knight in shining armor, because it kills bacteria and does not seem to hurt human tissue.
Credit must be given to the Belgian surgeon Antoine Depage, who during the First World War, stressed the need for cleaning or debriding wounds, and who used silver foil and powder to prevent bacteria from growing and infecting the wound. As a result, thousands of lives were saved.
After the war, silver colloids were introduced in which the silver was reduced to small particles to improve its efficacy. This remained the first line of defense against infection until the introduction of antibiotics in the 1940s.
In recent times, silver has come back into its own because of the increasing numbers of bacteria that have developed resistance to antibiotics.
One of the ways that silver kills germs is by binding to the bacterial structures that make critical enzymes. After exposure to silver, the bacteria die because they cannot ‘breathe.’ Silver does not affect the same structures in humans.
In the last 10 years, very small nanoparticles of silver have become available, with sizes in the range of 7 to 89 nm, which means that 100,000 nanoparticles, laid end to end, would make up the diameter of the full stop at the end of this sentence.”

“The antibacterial form of silver is the ions. Minute sub-particles [of metallic nanosilver – ED] continuously emit a sufficient number of positively charged ions. These destroy the enzymes of the bacteria, destabilize the cell membrane, the cell plasma or the cell wall and prevent their reproduction. The bacteria do not survive this concentrated attack.”

“This study aimed to investigate the effectiveness of silver in ionic and nano [i.e., metallic -- ED] form as antimicrobial toward a panel of L. monocytogenes isolates…The relation between the sensitivity assay and the amount of ions at the tested time points, in both cases (AgNPs and AgNO3) suggests that ions are the more effective elements exerting antibacterial activity … Our study suggests that L. monocytogenes is sensitive to silver and that the efficacy is linked to ionic release.”
