Gymnema, Gymnema Sylvestre, has been used by ayurvedic practitioners to treat type 2 diabetes for at least two thousand years. When it comes in contact with the tongue, Gymnema makes it impossible to taste sugar.

Peer-reviewed studies now support the use of Gymnema as a treatment for high blood sugar.
Gymnema is generally regarded as safe.
