Garcinia is a genus of tropical fruit-bearing trees and shrubs, primarily found in Southeast Asia and Africa. One of the most well-known species is Garcinia cambogia, which produces a small, green fruit that resembles a pumpkin. This fruit is often used in dietary supplements due to its potential weight loss benefits. The active ingredient in Garcinia cambogia is hydroxycitric acid (HCA), which is believed to help suppress appetite and inhibit fat production. While some studies suggest it may aid in weight management, more research is needed to fully understand its effectiveness and safety for long-term use.
