I have rheumatoid arthritis and its curios that Gold is used in the treatment of rheumatoid arthritis (RA) and has also been used for the treatment of other rheumatic and autoimmune diseases, including psoriatic arthritis and pemphigus vulgaris. Its use is limited by a high incidence of side effects, a requirement for close clinical and laboratory monitoring, and the need for gold sodium thiomalate (GST), the more efficacious form of gold, to be administered by periodic intramuscular injection.
