Colloidal silver "cure-all" OTC products not safe and effective -- FDA proposed rule.

COLLOIDAL SILVER-CONTAINING OTC PRODUCTS LACK SAFETY/EFFICACY DATA and would be misbranded under a proposed rule published by FDA in an Oct. 15 Federal Register notice. Comments on whether the substance can be generally recognized as safe and effective (GRAS) may be submitted to the agency within 90 days. Colloidal silver historically has been marketed with claims to treat a number of disease conditions.
