The seeds and oil of Hydnocarpus odorata, Lindley. (Nat. Ord. Flacourtiaceae). An East Indian tree.
Common Names: Chaulmoogra, Chaulmugra.
Principal Constituent.—A granular oil (Oil of Chaulmugra) containing gynocardic acid. It has an acrid taste. Dose, 2 to 3 drops.
Action and Therapy.—Oil of chaulmugra has given surprisingly good results in leprosy; and it has often failed. The dexterity with which it has been adulterated has probably stamped the medicine with an uncertain reputation. It is used both locally and internally. Many other uses, chiefly local, are ascribed to it, but the agent is seldom employed in this country, though it is of interest to physicians going to countries where leprosy abounds.
