Gotu kola is a perennial herb found in Africa, India, China and other parts of southeast Asia. A member of the parsley family, gotu kola has been part of Ayurvedic and traditional Chinese medicine for hundreds of years. Despite its familiar sounding name, gotu kola contains no cola or caffeine but it is a rich source of vitamin K. The active compound in gotu kola is triterpenoids. Evidence suggests that it helps brain function (including memory retention), promotes circulation and supports connective tissues. As an herbal dietary supplement, take 2 capsules, 2 to 3 times daily.
