Gymnema, also known as Gymnema sylvestre, is a woody climbing shrub native to India, Africa, and Australia. Its name, derived from Greek words meaning “naked thread,” refers to its woody stems.
For centuries, it has played a significant role in Ayurvedic medicine, where it is known as Meshashringee. The leaves and extracts of gymnema contain gymnemic acids, which interact with taste receptors on the tongue, temporarily suppressing the perception of sweetness. These acids block the taste of sugar, stevia, xylitol, and artificial sweeteners.
Additionally, gymnema can attach to receptors in the intestinal walls, reducing sugar absorption and promoting insulin secretion. While its antidiabetic properties are not confirmed in rats, research suggests that gymnema extracts may help reduce cravings for sugar and support weight loss.
