Colloidal Silver: Risk Without Benefit

In recent years, silver-containing products have been marketed with unsubstantiated claims that they are effective against AIDS, cancer, infectious diseases, parasites, chronic fatigue, acne, warts, hemorrhoids, enlarged prostate, and many other diseases and conditions. Some marketers claim that colloidal silver is effective against hundreds of diseases.






During 1997 and 1998, Changes International, a Florida-based multilevel company, stated:

Our colloidal silver contains 99.99% pure silver particles suspended indefinitely in demineralized water that kills bacteria and viruses. It can be applied topically and/or absorbed into the blood stream sub-lingually (under the tongue), thereby avoiding the negative effects of traditional antibiotics that kill good bacteria in the lower digestive tract.
It is impossible for single-celled germs to mutate into silver-resistant forms, as happens with conventional antibiotics. Also, colloidal silver cannot interact or interfere with other medicines being taken. Colloidal silver is truly a safe, natural remedy for many of mankind's ills. Colloidal silver can be taken indefinitely because the body does not develop a tolerance to it [1].

Seasilver International, a California-based multilevel company, had claimed that American are suffering from "silver deficiency." Although silver is not an essential nutrient, product information posted on the company's Web site several years ago stated:

The depletion of minerals in our soil has left us deficient of silver, one of our most essential trace minerals, causing a drastic increase in immune system disorders in our society in the last decade. Research has taught us that all disease is allowed to manifest itself because of a weakened immune system. In over 20 years of worldwide research on Colloidal Silver, numerous interviews with government agencies, health care practitioners and their patients, no other nutrient, herb or drug (prescription or over-the-counter) is as safe and effective against all known forms of unfriendly virus, bacteria, and fungus.

Critical Studies and Case Reports

In 1995, an herbal distributor named Leslie Taylor tested nine commonly marketed colloidal silver products available at health-food stores and concluded:

• Two of the products were contaminated with microorganisms.
• The amount of silver suspended in solution varied from product to product and would gradually decrease over time.
• Only five products actually showed antibacterial activity in a laboratory test. To perform the test, she prepared a culture plate with Staphylococcus aureas bacteria, which can cause infections in humans. She then placed a drop from each product on the plate and used disks of two common antibiotics as controls. After eight hours of incubation, she found that bacterial growth had been inhibited around the antibiotics and four of the products.

Of course, the fact that a product inhibits bacteria in a laboratory culture doesn't mean it is effective (or safe) in the human body. In fact, products that kill bacteria in the laboratory would be more likely to cause argyria because they contain more silver ions that are free to deposit in the user's skin.
FDA laboratory studies have found that the amount of silver in some product samples has varied from 15.2% to 124% of the amount listed on the product labels. The amount of silver required to produce argyria is unknown. However, the FDA has concluded that the risk of using silver products exceeds any unsubstantiated benefit [3]. So far, eleven cases of argyria related to silver products have been reported:

• A 56-year-old man who had sold and used colloidal silver for three years, developed blue/gray discoloration of his fingernails accompanied by a very high blood level of silver [4].
• A married couple who had three years of daily consumption of a drink prepared by administering an electrolytic charge to a bowl of water that contained a silver bar [5].
• Another couple had been taking a silver-containing "dietary supplement" prescribed by a naturopath [5].
• A mentally ill man who had been drinking silver-containing herbal tea for about 10 months [5].
• Stan Jones, Montana's Libertarian Party candidate for the U.S. Senate, who reportedly started taking colloidal silver in 1999 for fear that Y2K disruptions might lead to a shortage of antibiotics. He made his own concoction by electrically two silver wires in a glass of water [6].
• Two men, ages 63 and 76, developed argyria after a year of product use inspired by Internet claims [7].
• A 16-year-old boy developed blue-gray pigmentation of his entire body after ingesting a silver-containing dietary supplement for a year. The product, packaged so that it was identical to bottled water. was touted as a preventive for everyday infections [8].

• A 58-year-old man who treated a presumed kidney infection with a home-brewed colloidal solution 12 times a day for 4 days developed argyria about 4 weeks later [9].
• A 38-year-old man developed argyria after ingesting approximately 16 ounces of 450 ppm colloidal silver three times a day for 10 months to treat his arthritis and other conditions. He made the solution with a simple battery-operated chamber that leached silver from pure silver wire. He had obtained the plans from information on the Internet [10].

Enforcement Actions

Between October 1993 and September 1994, the FDA issued warning letters to five colloidal silver marketers::

• Higher Education Library Publications (H.E.L.P.), of Springfield, Utah, was ordered to stop claiming that its colloidal silver product was effective as a natural antibiotic and might be effective against cancer, genito-urinary diseases, tuberculosis, and AIDS.
• Nutrition, Inc., of Arvada, Colorado, was ordered to stop stating or implying that its Silvicidal, when administered orally or intravenously, was nontoxic, FDA-approved, and was a broad-spectrum antibiotic that killed bacteria and all virus and fungal infections. In addition, it was falsely claimed to be effective against a long list of specific diseases.
• Reseau International of Cincinnati, Ohio was ordered to stop claiming that its colloidal silver product was a "natural antibiotic and anti-inflammatory immune system stimulant" and that it was effective against cancer, staph, strep, influenza, general body infections, inflammation, impaired immune system, fungus toxicity, tonsillitis, Meniere's symptoms, whooping cough, shingles, syphilis, cholera, and malaria. The labeling also stated that colloidal silver could cause major growth stimulation of human tissues and can regenerate
• Silverado Inc., of Bountiful, Utah, was warned to stop making false claims that its colloidal silver product was effective as an antibiotic, anti-inflammatory, anti-viral, and anti-fungal agent and that it could stimulate the immune system.
• Unic, of Carmichael, California, was ordered to stop claiming that its colloidal silver product was effective against many diseases and could heal burn-damaged tissue without scarring.

In October 1996, the FDA proposed to ban the use of colloidal silver or silver salts in over-the-counter products [11]. A Final Rule banning such use was issued on August 17, 1999 and became effective September 16th. The rule applies to any nonprescription colloidal silver or silver salt product claimed to be effective in preventing or treating any disease [12]. Silver products can still be sold as "dietary supplements" provided that no health claims are made for them. During 2000, the FDA issued warnings to more than 20 companies whose Web sites were making illegal therapeutic claims for colloidal silver products.
