Myrobalan (Terminalia chebula) is a medium to large deciduous tree growing to 30 m tall. Its leaves are oval with alternate to subopposite arrangement. The fruit is drupe-like, blackish, with five longitudinal ridges. Its dull, white to yellow flowers have a strong, unpleasant odour. The myrobalan plant is found throughout South-East Asia including India, Sri Lanka, Bhutan, Nepal, Bangladesh, Myanmar, Cambodia, Laos, Vietnam, Indonesia, Malaysia, Pakistan and Thailand.
In India, it is found in the sub-Himalayan region from Ravi eastwards to West Bengal and Assam, ascending up to the altitude of 1,500 m in the Himalayas.
Dry myrobalan is the main ingredient in the Ayurvedic formulation Triphala used for kidney and liver dysfunctions. The dried fruit of the plant is also used as an anti-tussive, cardiotonic, homeostatic, diuretic, and a laxative.
A number of glycosides including the tri-terpenes, arjunglucoside I, arjungenin, and the chebulosides I and II have been isolated from the plant. Other constituents include coumarin conjugated with gallic acids and phenolic compounds. Terflavin B, a type of tannin is also found in the herb.
