An Ayurvedic herb that’s creeping into a range of products

The thin, creeping gotu kola plant has been used in Ayurvedic, or traditional Indian, medicine for hundreds of years. In parts of Southeast Asia, the plant’s leaves are reputed to increase longevity and sharpen memory. In the United States, gotu kola is available as a herbal supplement, and recently it has been popping up in products from health drinks to shaving gels.

Uses: Gotu kola is used for skin conditions, including psoriasis, burns, wounds and scars. Some people also take it to treat varicose veins, sleep disorders, high blood pressure and anxiety, and to improve memory and concentration.

Dose: Usually, 200 milligrams two to three times a day in pill form or two cups of tea daily for up to six weeks. A couple of teaspoons of dried gotu kola leaves also can be used to make a compress.

Precautions: Gotu kola may cause skin rashes and headaches and may increase some users’ susceptibility to sunburn.

Research: A few small studies suggest that gotu kola may help heal burns and wounds, treat leprosy, strengthen veins and relieve some of the symptoms of anxiety, but very little clinical research has been done on the herb in the United States.
