Description of the plant:
A small, woody, annual shrub. Leaves almost reniform, distinctly cordate-auriculate, 3-5-7 lobed. Inflorescence proliferous, forming many lateral spurs that carry two or more flowers. Bracteoles 3, equalling the capsule, ovate-rotund, top incised into long irregular teeth. Flowers large, yellow with purple claws. Capsules ovoid, acuminate.
Flower extract is used as an abortifacient and to induce menstrual flow. Seeds are demulcent, laxative, expectorant and aphrodisiac. Roots are emmenagogue and galactagogue; useful in dysmenorrhoea and suppression of menstruation. Root bark stimulates uterine contractions and hastens difficult labour. It promotes abortion or onset of menstruation and reduces menstrual flow (Yusuf et al. 2009).
Leaf extract possesses antibacterial activity (Gani, 2003).
Leaves, flowers, roots, stem and seed oil contain an active constituent, a sesquiterpene pigment, called gossypol (a dimeric naphthalene derivative), which causes infertility in men. Other constituents of various parts of the plant include flavonids, quercetin, betaine, choline and salicylic acid. Root bark contains resin (Gani, 2003).
