What is Gotu Kola?
Centella asiatica is a perennial creeping herb in the carrot family. The plant is also known as gotu kola and grows abundantly in shady, moist, or marshy areas. It is distributed widely in many parts of the world, including India, Sri Lanka, Madagascar, South Africa, Australia, China, and Japan.
What is it used for?Traditional/Ethnobotanical uses
Gotu kola has a long history of use in numerous medical systems. In India, the plant has been used to treat skin inflammation, diabetes, cough, cataracts and other eye conditions, and to improve memory. In Europe, an infusion of the aerial parts of the plant was used to purify the blood and treat wounds, ulcers, skin inflammation, and hypertension. A similar infusion has been used in Indonesia and Brazil to help improve memory. In Malaysia, the plant was used to treat respiratory ailments, such as bronchitis and asthma, and stomach complaints, including dysentery, kidney trouble, inflammation of the urethra, and swelling. In Malaya, an infusion from this plant is sold as a tonic and cold beverage to treat liver ailments, tuberculosis, and blood in the urine. In the past, people in Japan valued the plant for its diuretic and detoxicant properties. Sri Lankans noticed that elephants, known for their longevity, ate the leaves of the plant. Thus, the leaves were believed to promote long life, with a suggested “dosage” of a few leaves each day.
