Use of silver preparations can lead to argyria, a condition in which silver salts deposit in the skin, eyes (argyrosis), and internal organs, and the skin turns ashen-gray. Many cases of argyria occurred during the pre-antibiotic era when silver was a common ingredient in nosedrops. When the cause became apparent, doctors stopped recommending their use, and reputable manufacturers stopped producing them. The official drug guidebooks (United States Pharmacopeia and National Formulary) have not listed colloidal silver products since the 1970s (1975?).
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 tremendously from product to product and would gradually decrease over time.
Only three 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 only three of the products.
Of course, the fact that a product inhibits bacteria in a laboratory culture does NOT mean it is effective (or safe) in the human body, high doses of chlorine will kill germs too. 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 tissues.
Independent 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. So far, one hundred eleven cases of argyria related to silver products have been reported.
Argyria is generally believed to be irreversible, with the only practical method of minimizing its cosmetic disfigurement being to avoid the sun, but laser therapy has been used to treat it with mixed results. The Agency for Toxic Substances and Disease Registry (ATSDR) describes argyria as a "cosmetic problem", which is not life threatening, it is mildly disfiguring and thus some people find it to be socially debilitating.
