Leaf juice mixed with oil is applied to sinuses and scrofulous sores. A vapour bath prepared from the leaves is used for treating febrile, catarrhal and rheumatic affections. Leaves are used for diarrhoea in Rema-Kalenga. Leaf-boil water is used for bath to relieve post-partum pains in Jointiapur of Sylhet. Leaves are used for asthma and hair growth in Khagrachari. Roots are tonic, febrifuge, expectorant and diuretic. Fruits are nervine, cephalic and emmenagogue; dried fruit acts as a vermifuge. Flowers are astringent and cooling. Chloroform extract of the leaf possesses strong antibacterial properties against wide range of human pathogenic bacteria (Begum, 2001).
Hentriacontane, sterols, β-sitosterol, β-sitosterol acetate, stigmasterol, ascorbic acid, p-hydroxybenzoic acid, carotene and amino acids have also been isolated from this plant. Leaves contain a pale greenish yellow essential oil, an alkaloid, nishindine and a glucoside. Stem bark contains flavonoid glycosides of wogonin, aurosin, vitexin, myricetin, also luteolin, leucodelphinidin, luecocyanidin rhammoside, β-sitosterol, vanillic acid and p-hydroxybenzoic acid (Ghani, 2003). n-Tritriacontane, n-hentriacontane, n-pentatriacontane, n-nonacosane, β-sitosterol, p-hydroxybenzoic acid and 5-oxyisophthalic acid have been isolated from seeds (Rastogi & Mehrotra, 1993). The plant extract contains estrogen, testosterone and progesterone, with concentrations of 947.7 pg/ml, 22.276 ng/ml and 6.022 ng/ml respectively. This high concentration of steroid hormones may contribute to its contraceptive action (Khan et al., 2006).
