Small to medium deciduous tree with rough bark and trifoliate leaves, flowering on the leafless branch; native range: the dry deciduous forests of the Indian subcontinent, on hills and rocky ground through the sub-Himalayan tract and central India. Globally recognized as tiniśa · syandana · rathadru · jīvana in Sanskrit, tinsa · sandan · panjan in Hindi, and tinsa · Indian chariot tree in English. The part used is the bark; also the leaf and the gum. Rough, dark grey bark, exfoliating in irregular flakes and reddish-brown within, tough and fibrous where it is cut; the taste astringent and bitter, puckering the mouth.
