Background

Banaba is a medicinal plant that grows in India, Southeast Asia, and the Philippines. Banaba has been used for blood sugar control. The hypoglycemic (blood sugar lowering) effect of banaba leaf extract is similar to that of insulin, which induces glucose transport from the blood into body cells.

Currently, research suggests that taking banaba extract, standardized to 1% corosolic acid, by mouth may lower blood sugar in people with type 2 diabetes, however further evidence is needed before a firm conclusion can be made.

Evidence

Diabetes: Preliminary research investigating the effects of banaba on diabetes report promising results. However, additional research is necessary before a firm conclusion can be made.
