Gotu kola is a small, ground-hugging plant grown in India, Pakistan, Madagascar and South Africa. It is also found in Eastern Europe. In Sri Lanka, the plant’s leaves are consumed by both humans and animals, especially elephants.
Gotu kola has historically been reported to enhance mental activity and help a variety of illnesses, including rheumatism, fevers and high blood pressure. It is a staple in ayurvedic medicine; some of its more common uses are for cardiovascular disease, water retention, bronchitis and coughs. Practitioners also make a poultice out of gotu kola, which is used to treat many skin conditions.
