The name of the plant which affords the palm oil, O'leum pal'mae, obtained chiefly from the fruit, by bruising and mixing the kernels with water, without the aid of heat, by which the oil is separated and rises to the surface. It is of the consistence of an ointmeut, with little taste, and a strong, though not disagreeable, smell. It is applied to sprains, &c.; but has no advantages over other oils. It has been used as the excipient for suppositories, and has been called, also, O'leum Palmae seba'ceum, O. fix'um nucum cocos butyra'ceae and Mackaw fat. It is procured likewise from the Ela'is Guineen'sis, and Ela'is Occidenta'lis, two species of palms. Cocos is said to be contracted from (P.) macoco or macaco, 'a, monkey,' the three holes at the end of the cocoa-nut shell causing it to resemble somewhat a monkey's head.
