Kameela, Or Kamala, the glandular powder and hairs obtained from the capsules of Rott-lera tinctoria, a small tree of the order euphor-biacece growing in the East Indies. The finest, consisting of roundish three-celled capsules, is gathered in February and March, and the light, mobile, brownish red powder formed by the glands and hairs, brushed off. This consists in a large proportion (78 per cent.) of resins, one or more of which is supposed to be the active principle. Kameela is actively purgative in full doses, sometimes acting violently, and occasionally causing nausea, but seldom vomiting. It has been long used in India in the treatment of tapeworm, and seems to have been found very efficient by the British practitioners in that country. It has, however, only within a few years been used in Europe and America. It is given, without previous preparation of the patient, in the dose of from one to three drams, suspended in water, mucilage, or sirup. A tincture has been employed. The bark of another species of the genus, R. Schimperi, growing in Abyssinia, has been supposed also to possess anthelmintic properties.

When kameela is administered in cases of tapeworm, the worm is usually expelled with the third or fourth stool.
