Colloidal silver is available as a supplement and can be found in many health stores as well as over the internet (of course) and is mostly marketed as a “cure-all-treatment”, with claims that it cures ailments and illnesses ranging from HIV to herpes and cancer. The fact is that colloidal silver is not an essential mineral, as often claimed, nor does it have any known purpose in the body. It is not even considered safe to ingest.
