Can Colloidal Silver Cure Swine Flu?

Wednesday, June 3, 2009
As the H1N1 swine flu continues to spread, you may be seeking a powerful defense against this potentially life-threatening virus. Manufacturers of colloidal silver—a solution of tiny silver particles suspended in a liquid base—claim that their products can knock out swine flu, as well as protect against flu-related secondary infections such as pneumonia. However, there's little scientific evidence that colloidal silver can actually stave off disease or infection. What's more, this supplement may lead to adverse effects like argyria (an untreatable, permanent characterized by bluish discoloration of the skin).

Claims for the flu-fighting powers of colloidal silver are rampant on the Internet. But it's crucial to take caution when reviewing these claims: In a 2008 analysis of 49 websites providing information on silver-containing nasal sprays (one form of colloidal silver), researchers found that all linked to shopping sites where such products could be purchased.
