Gymnema Sylvestre is native to India, predominantly in tropical forests of India. This herb has traditionally been used in the Indian eclectic alternative medical system as the naturopathic treatment for diabetes. The active ingredients or bioactive constituents are a group of gymnemic acids, which have antidiabetic and anti-inflammatory as well as antisweetener properties. If used for a while, gymnema sylvestre, or rather the gymnemic acids, have the effect of reducing the blood sugar level. These glycosides are found in an extract of the leaves and it seems that the acids have a similar structure to saccharose. Besides the gymnemic acids, the plant contains also saponins, quercitol, stigmasterol and also some amino acid derivatives, namely trimethylamine, betaine and choline. When the leaves of gymnema sylvestre are chewed, you temporarily lose the ability to taste sugar.
