Every part of the plant is purgative, but the fruit or seeds are dangerously so, and in the medicinal practice of Europe they are never given, though in India native practitioners sepa rate the embryo, and give it internally. The seeds yield a powerfully cathartic oil, by grinding the seeds, placing the powder in bags, and pressing it between plates of iron. The oil is then allowed to stand 1.5 days, and afterwards filtered. The residue of the expression is saturated with twice its weight of alcohol, heated on a sand-bath from 120° to 140° Fahr., and the inixture pressed again ; the alcohol is distilled off, the oil allowed to settle, and filtered after a fortnight. One seer (2 lbs.) of seed furnishes 11 fluid ounces of oil,— 6 by the first process, 5 by the second.
