Description of the Plant:
A bulbous herb; with truncate bulbs, 5-10 cm long, ovoid. Leaves radical, appearing after the flowers, 15-45 cm long, linear, acute. Scape erect, 30-45 cm long. Flowers small, dingy brown, very distant, on slender, laxly flowered racemes, 15-30 cm long. Capsules 1.3-2 cm long, ellipsoid, tapering to both ends.
Bulb is diuretic and cardiac stimulant; used chiefly as a powerful expectorant in the treatment of cough, especially in chronic bronchitis and asthma; in large doses it is emetic and cathartic and may cause cardiac depression. Its cardio–tonic activity resembles that of digitalis. The extract of bulb also shows hypoglycaemic and anticancer activity.
Bulb, which constitutes the drug, contains cardiac glycosides. It also contains various flavonoids including quercetin derivatives and kaempferol polyglycosides, sinistrin, mucilage and calcium oxalate (Ghani, 2003). Fresh squill yields at least two glycosides, scillaren-A and scillaren-B (Chopra et al., 1992).
