Garcinia cambogia is native to India and Southeast Asia. The fruit pulp and rind have long been used in Asian countries as a condiment and food preservative. The rind contains a chemical called hydroxycitric acid (HCA), which has been studied for its effect on appetite. Garcinia cambogia supplements with HCA are marketed for weight loss. Garcinia cambogia has also been promoted for relief of joint pain and digestive symptoms and to improve athletic performance.
