EtOH(50%) extract of aerial parts is diuretic; that of leaves graded analgesic in albino mice and antiinflammatory in carrageenin-induced oedema in rats (Asolkar et al., 1992). The crude extract of the root showed in vitro antihistamic activity on tracheal chain, but prevention of anaphylactic shock was partial (Ahmed et al., 2005).

Chemical constituents:
Aerial parts contain the alkaloids, acanthicifoline, oleanolic acid, ß-sitiosterol, lupeol, quercetin, its glucopyranoside and trigonelline. Roots contain triterpenoid, saponin and glycosides (Asolkar et al., 1992). Apigenin-7-O-glucuronide and a new flavone glycoside, methylapigenin-7-O- ß-D-glucuronate has been isolated from the leaves (Ghani, 2003).
