Terminalia chebula, commonly known as chebulic myrobalan, is a species of Terminalia, native to South Asia from India and Nepal east to southwest China (Yunnan), and south to Sri Lanka, Malaysia, and Vietnam. Terminalia chebula is a medium to large deciduous tree growing to 30 m (98 ft) tall, with a trunk up to 1 m (3 ft 3 in) in diameter. 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 (4,900 ft) in the Himalayas. This tree is wild in forests of Northern India, central provinces and Bengal, common in Madras, Mysore and in the southern part of the Bombay presidency. Terminalia chebula is the main ingredient in the Ayurvedic formulation Triphala which is used for kidney and liver dysfunctions. The dried fruit is also used in Ayurveda as a purported antitussive, cardiotonic, homeostatic, diuretic, and laxative.
A number of glycosides have been isolated from haritaki, including the triterpenes arjunglucoside I, arjungenin, and the chebulosides I and II. Other constituents include a coumarin conjugated with gallic acids called chebulin, as well as other phenolic compounds including ellagic acid, 2,4-chebulyl-β-D-glucopyranose, chebulinic acid, gallic acid, ethyl gallate, punicalagin, terflavin A, terchebin, luteolin, and tannic acid. Chebulic acid is a phenolic acid compound isolated from the ripe fruits. Luteic acid can be isolated from the bark.
Terminalia chebula also contains terflavin B, a type of tannin, while chebulinic acid is found in the fruits.
Myrobalan is a great dye to modify colours on cotton. On its own it produces butter yellows. We employ the fresh myrobalan form the local market to produce beautiful light to dark yellow and grey & green shades on cotton, wool, silk and all natural textile substrates by standardized dyeing process using different combination of other mordants on fibers, fabric and garments with excellent fastness properties.
