Terminalia chebula (Yellow Myrobalan or Chebulic Myrobalan; Sinhala: අරළු (Aralu), Tamil:கடுக்காய்(Kadukkai);മലയാളം [ "കടുക്ക" ] Assamese: Xilikha; Urdu: ہریڑ; Chinese: 诃子 he zi; Gujarati: Himmej; Telugu: Karakkaya; Sanskrit: harītakī, हरीतकी; Bangla: হরিতকী / হর্তুকি (harītakī); Tibetan: A-ru-ra) is a species of Terminalia, native to southern Asia from India and Nepal east to southwestern China (Yunnan), and south to Sri Lanka, Malaysia and Vietnam.
It is a deciduous tree growing to 30-metre (98 ft) tall, with a trunk up to 1-metre (3 ft 3 in) in diameter. The leaves are alternate to subopposite in arrangement, oval, 7–8-centimetre (2.8–3.1 in) long and 4.5–10-centimetre (1.8–3.9 in) broad with a 1–3-centimetre (0.39–1.18 in) petiole. The fruit is drupe-like, 2–4.5-centimetre (0.79–1.77 in) long and 1.2–2.5-centimetre (0.47–0.98 in) broad, blackish, with five longitudinal ridges.
- Terminalia chebula var. chebula. Leaves and shoots hairless, or only hairy when very young.
- Terminalia chebula var. tomentella (Kurz) C.B.Clarke. Leaves and shoots silvery to orange hairy.
Cultivation and uses
This tree yields smallish, ribbed and nut-like fruits which are picked when still green and then pickled, boiled with a little added sugar in their own syrup or used in preserves; this preserve is called 'Hareer Ka Murabba (ہریڑ کا مربہ) in Urdu language. The seed of the fruit, which has an elliptical shape, is an abrasive seed enveloped by a fleshy and firm pulp. It is regarded as a universal panacea in the Ayur-Vedic Medicine and in the Traditional Tibetan medicine. It is reputed to cure blindness and it is believed to inhibit the growth of malignant tumours.
In Hindi it is called Harad, Haritaki, or Harada, respectively 'Inknut'. In Urdu it is called 'Hareer'. In Sri Lanka it is called Aralu. In Marathi it is called as 'Hirada', in Kannada it is called 'Alalekaayi', in Tamil it is called 'Kadukkai' and in Malayalam it is known as 'Kadukka'. In Bengali it is called horitoky. In Assamese it is called silikha. In Telugu it is called 'Karakkaya'. In the United States it is found in some Indian stores; it is known as 'Harde Whole'.
The dry nut's peel is used to cure cold-related nagging coughs. The bark/peel of the nut is placed in the cheek. Although the material does not dissolve, the resulting saliva, bitter in taste, is believed to have medicinal qualities to cure cold related coughs. Its fruit has digestive, anti-inflammatory, anthelmintic, cardiotonic, aphrodisiac and restorative properties and is additionally beneficial in flatulence, constipation, piles, cough and colds.
Medium to large deciduous tree up to 30 m. Leaves are elliptic-oblong, acute tip, cordate at the base, margins entire, glabrous above with a yellowish pubescence below. Flowers monoecious, dull white to yellow, strong unpleasant odour, borne in terminal spikes or short panicles. Fruits glabrous, ellipsoid to ovoid drupes, yellow to orange brown in colour, single angled stone. Found in deciduous forests of Indian subcontinent, dry slopes up to 900 meters in elevation
Fruit; seven types are recognized (i.e. vijaya, rohini, putana, amrita, abhaya, jivanti and chetaki), based on the region the fruit is harvested, as well as the colour and shape of the fruit. Generally speaking, the vijaya variety is preferred, which is traditionally grown in the Vindhya mountain range of central India, and has a roundish as opposed to a more angular shape
Researchers have isolated a number of glycosides 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.
In Tamil, "Kadukkai"
