Gamboge : Both the rind and extract of this tree crop are found in curry dishes in India, where they also hold an esteemed place in the ancient Ayurvedic system of healing. The mechanism for bringing down body weight is found in hydroxycitric acid (HCA), which helps to suppress and control appetite while inhibiting the conversion of excess calories to body fat. Gambooge is used for rheumatism, bowel complaints—including constipation and intestinal parasites—edema and delayed menstruation. Some devotees of the gambooge fruit attest to its ability to increase energy levels. Studies also suggest that gambooge protects the liver against alcohol and other external toxins. Damage to liver cells caused by high blood lipid levels is reduced when this botanical is added to the list of effective supplements.
