Corosolic acid is a pentacyclic triterpenoid compound found in the leaves of the Banaba tree (Lagerstroemia speciosa). It is known for its anti-diabetic properties, as it can help to lower blood glucose levels. Corosolic acid is believed to work by enhancing glucose uptake into cells, improving insulin sensitivity, and inhibiting the enzymes that break down carbohydrates.
