  schema:description "Colloidal silver is promoted as a cure for cancer, AIDS and infections, with no human evidence that taking it by mouth does anything useful. Long-term use deposits silver in the skin and turns it permanently blue-grey, and it has caused seizures, kidney damage and nerve damage. It should never be used in pregnancy."@en ;
