Centella Asiatica, also known as Gotu Kola or Pennywort, is used abundantly in the ancient healing tradition of Ayurveda. This charming herb with bright red flowers, grows naturally in hot, swampy areas in India and Sri Lanka. The plant’s leaf is most commonly used medicinally, and is a favorite food of elephants, notoriously long-lived animals, which has led many people to associate Centella with longevity.
