Executive Summary
Eight FDA letters sent in early January to Web sites selling colloidal silver products advise the agency "has no information that your product is [GRAS/E] for the referenced conditions." Products may be considered "new drugs" under the FD&C Act and may not be legally marketed without FDA approval, the agency maintains. The sites claim colloidal silver products "mitigate more than 650 types of infections" and "destroy over 600 germs and bacteria," according to the letters. In a final rule issued in August 1999, FDA declared silver constituents in OTC drugs for internal or external use not GRAS/E (1"The Tan Sheet" Aug. 23, 1999, p. 5)
