EUPHORBIUM, in the materia medica; a gum resin, brought us always in loose, smooth, and glossy gold-coloured drops or granules. It is the produce of the euphorbium antiquorum verum, which grows to 10 or 12 feet high. Its principal use is externally in sinapisms, and plasters applied to the feet, which are intended to stimulate, but not absolutely to raise blisters: for it is observed by Avisenna, that, when taken internally in large doses, it has been found to exulcerate the intestines, and bring on death itself after the most terrible symptoms.
