Garcinia cambogia is native to parts of South East Asia, India, Indonesia and in some parts of central Africa where there are rain forests. The extract comes from the fruit of the tree. The fruit is shaped like a pumpkin, and it is its rind from which we get the extract. Where it is found in Asia, it has been a part of the diet for hundreds of years. It is used mainly as a condiment for sea food, and its sharp taste is used to add taste to curries much in the same way that tamarind is used.
