Senegalia catechu is a deciduous, thorny tree which grows up to 15 m (50 ft) in height.[3] The plant is called khair [4] in Hindi, and kachu in Malay, hence the name was Latinized to "catechu" in Linnaean taxonomy, as the type-species from which the extracts cutch and catechu are derived.[5] Common names for it include kher,[6] catechu, cachou, cutchtree, black cutch, and black catechu.
Senegalia catechu is found in Asia, China, India and the Indian Ocean area.[2]
Through derivatives of the flavanols in its extracts, the species has lent its name to the important catechins, catechols and catecholamines of chemistry and biology.

Uses
Food
The tree's seeds are a good source of protein.[7] Kattha (catechu), an extract of its heartwood, is used as an ingredient to give red color and typical flavor to paan. Paan is an Indian and Southeast Asian tradition of chewing betel leaf (Piper betle) with areca nut and slaked lime paste.
Fodder
Branches of the tree are quite often cut for goat fodder and are sometimes fed to cattle.[2][7]
Medicinal uses
The heart wood and bark of the tree are used in traditional medicine.[8] A wood extract called catechu is used in traditional medicine for sore throats and diarrhea.[3] The concentrated aqueous extract, known as khayer gum or cutch, is astringent.[9] It is used in Ayurvedic medicine.[10] In ayurveda, it is used for rasayana (rejuvenation treatments). It is also used for its actions like anti-dyslipidemic, anthelminthic, anti-inflammatory, anti-diuretic, anti-pruritic, coolant, taste promoting, enhancing digestion and curing skin disorders.[11] It is also used as a teeth cleaning twig, with some sources naming it "the original" such twig.[12]
Wood
The tree is often planted for use as firewood and charcoal and its wood is highly valued for furniture and tools.[3] The wood has a density of about 0.88 g/cm3.[13]
Other uses
Its heartwood extract is used in dyeing and leather tanning, as a preservative for fishing nets, and as a viscosity regulator for oil drilling.[3]
Cultivation
The tree can be propagated by planting its seeds, which are soaked in hot water first. After about six months in a nursery, the seedlings can be planted in the field.[3]
