Description of the plant:
A medium-sized deciduous tree with tall cylindrical bole and spreading crown. Leaves pinnately compound, 7-20 cm long; leaflets 6-10 pairs, elliptic-oblong, mucronate. Flowers white in slender, axillary, pubescent racemes. Fruit a pod, up to 7 cm long, linear, narrowed at both ends.

Using information:
Broken or wounded limbs are treated with slightly warmed leaves of these plants to reduce pain and aid healing. Root juice mixed with the juice of Sida acuta is used for sore throat by the Marma (Yusuf et al. 2009).

Alcoholic extract of seeds showed significant in vitro activity against some human and plant pathogenic bacteria; also antifungal against keratinophilic fungi and related dermatophytes (Asolkar et al., 1992).
Chemical constituents:
Seed shell contains chalcone rubone; isoflavone derrugenin; rubustigenin, its 5-Me ether; derrusnin, methyl ethers of robustone and robustin, alpinum, isoflavone di-Me-ether, β-sitosterol & its glucosides; 5-OH-7-OMe-isoflavone; derrone, its Me-ether. Roots contain 4 isoflavones, derrustone, derrubone, robustone and its Me ether, and 5 coumarins, derrusnin, robustic acid and their Me esters (Asolkar et al.,1992). 5-hydroxy-7-methoxyisoflavone has been isolated from seeds (Rastogi & Mehrotra, 1993).
