Some purported benefits of Gymnema sylvestre extract include treatment for a variety of conditions, such as diabetes, metabolic syndrome, malaria and cough. However, as of 2015, published related scientific literature remains insufficient to support these claims, notes WebMD.
The extract of the gymnema plant is said to contain chemicals that reduce intestinal absorption of sugar. Early studies indicate that this mechanism can be triggered through oral intake of gymnema extract in addition to diabetes medications and insulin. This form of treatment is said to manage type 1 and type 2 diabetes.
Early research also show that orally taking gymnema extract as an adjunct to niacin-bound chromium and hydroxycitric acid for 2 months can result in weight loss, states WebMD. theless, the medical field do not consider these health claims as definitive due to the lack of corroborative clinical proof.
