"The Food and Drug Administration (FDA) is issuing a final rule
establishing that all over-the-counter (OTC) drug products containing
colloidal silver ingredients or silver salts for internal or external use are
not generally recognized as safe and effective and are misbranded. FDA
is issuing this final rule because many OTC drug products containing
colloidal silver ingredients or silver salts are being marketed for
numerous serious disease conditions and FDA is not aware of any
substantial scientific evidence that supports the use of OTC colloidal
silver ingredients or silver salts for these disease conditions."
