6/7/14: This week on "The Plant Detective:" For thousands of years, people in India, China, and Indonesia have used gotu kola to heal wounds, improve mental clarity, and treat skin conditions such as leprosy and psoriasis. Today, in the U.S. and Europe, gotu kola in ointment helps heal minor wounds and taken in other forms, it treats varicose veins and chronic venous insufficiency. The Chinese use it to reduce stress.
Don't confuse gotu kola with cola or cola nut. They're completely different plants.
