Gotu Kola (Centella asiatica) is indigenous to the Indian subcontinent, Southeast Asia, and wetland regions of the Southeastern U.S. Historically, gotu kola has been used to treat syphilis, hepatitis, stomach ulcers, mental fatigue, epilepsy, diarrhea, fever, and asthma. Today, in some parts of the world, gotu kola is used to treat varicose veins and chronic venous insufficiency, a condition where blood pools in the legs.
