A medium to large, deciduous tree, up to 18 m high. Leaves paripinnate, 30-60 cm long, somewhat crowded at the ends of branchlets; leaflets 10-20, oblong-lanceolate, often falcate with oblique base, 5-12 cm long. Flowers small, white, in terminal pyramidal, cymose panicle. Capsule oblong, 2-2.5 cm long, dark brown when mature.
Bark is powerful astringent, expectorant, tonic and valuable antiperiodic; in the form of infusion it is given in fevers, rheumatism and chronic infantile dysentery; as a local astringent it is applied in various forms of ulceration. Flowers are considered emmenagogue; used in menstrual disorders. Alcoholic extract of the leaf possesses moderate antibacterial and antifungal properties (Taniya, 2004).
Flowers contain a red colouring matter, nyctanthin and a flavanol dyestuff containing quercetin. Bark contains tannic acid, a bitter resin, a phlobaphene, citric acid and starch. Wood contains an essential oil consisting of tricyclic sesquiterpene, copaene and bicyclic hydrocarbon, cadinene and a lactone, a reddish yellow dye, leucocyanidins and tannin (Ghani, 2003). Cedrelone, 1,2-dihydrocedrelone, bergapten and β-sitosterol and a new tetranortriterpenoid-6-deoxycedrelone have also been isolated from this plant (Rastogi & Mehrotra, 1993).
