Iboga Overview
Iboga is a shrub native to Central and West Africa that has been used in traditional medicine and spiritual practices. Its root bark contains a number of alkaloids, including ibogaine, which has hallucinogenic and stimulant properties. Iboga has been studied in regard to its use in those suffering from alcohol and drug addiction, but the main constituent of Iboga (ibogaine) is a schedule I controlled substance in the United States, and possession is illegal. Its use as a traditional medicine is generally not recommended due to safety concerns.
Penicillamine Overview
-
Penicillamine is used to treat Wilson's disease (an inherited condition that causes copper to build up in the body and may result in serious symptoms) and cystinuria (an inherited condition which can lead to kidney stones). It is also used in combination with other treatments to treat severe rheumatoid arthritis (a condition in which the body's immune system attacks its own joints, causing pain, swelling, and loss of function) that did not get better after treatment with other medications. Penicillamine is in a class of medications called heavy metal antagonists. It works to treat Wilson's disease by binding to the extra copper in the body and causing it to leave the body through the urine. It works to treat cystinuria by binding to the substance that makes kidney stones and preventing it from building up and forming stones. It works to treat rheumatoid arthritis by decreasing some actions of the immune system.
