Gymnema Sylvestre, often called the “sugar destroyer,” is an herb with a long history of use in traditional Ayurvedic medicine for managing diabetes and blood sugar levels.
Modern research has begun to uncover the mechanisms behind its effects, revealing how Gymnema can benefit people with high blood sugar or insulin resistance.
What is Gymnema Sylvestre?
Gymnema Sylvestre is a climbing shrub native to India, Africa, and Australia. Its leaves contain unique compounds, such as gymnemic acids, that are believed to contribute to its blood sugar-lowering effects.
In Ayurvedic medicine, Gymnema has been used for centuries to treat diabetes and support healthy metabolism. Recent studies indicate that these traditional uses may indeed have scientific backing.
