Description of the Plant:
An annual erect herb, up to 60 cm tall; stems solitary or few, corymbosely branched; branches ascending. Leaves up to 3.8 cm long, linear-lanceolate, acute. Flowers blue, about 2.5 cm across, in corymbose panicles. Capsules ovoid, mucronate.
The seeds are tonic, diuretic, aphrodisiac and demulcent; used in ulcers, leprosy, cough and kidney troubles. Poultices of seeds are recommended for gouty and rheumatic swellings; as an emollient the mucilage is dropped into the eye; with honey it is prescribed in coughs and colds; given internally for gonorrhoea and irritation of the genito-urinary system. Roasted seeds are astringent. The oil mixed with lime is a popular remedy to the pain of burns. The flowers are considered to be a nervine and cardiac tonic (Yusuf et al. 2009).
Seeds contain a large quantity (30-40%) of fixed oil (composed of 36-50% linolenic acid and 23-24% linoleic acid), proteins (16-31%), principally two globulins, linin and colinin mucilage (6%), small amount of enzyme linase, a cyanogenetic glycoside, linamarin and two other glucosides and also phytin, lecithin, phosphates, wax, resin, sugar and carotenoids, particularly β-carotene (Ghani, 2003). Cholesterol, campesterol, stigmasterol, sitosterol, 5-dehydro-avenasterol, cycloartenol and 24-methylenecycloartanol (2%) have also been isolated from seeds (Rastogi and Mehrotra, 1993).
