Chaulmoogra oil
The oil from the seeds of Hydnocarpus wightianus (Chaulmoogra) has been widely used in various forms of traditional Indian medicine and in
The chemical constituents of the oil were analyzed for their potential pharmacological activity by Frederick Belding Power, working for Wellcome Chemical Research Laboratories, in 1904.[7] Power and colleagues isolated hydnocarpic acid, which had the formula , from seeds of both the Hydnocarpus Wightiana and Hydnocarpus anthelmintica trees.
Physical characteristics and composition
The oil is semi-solid at room temperature with no odor.
The crude oil has a pale greenish-brown color, and can be easily purified into a white, watery oil containing three cyclopentene

Extraction
Seeds are ovoid, irregular and angular, 1 to 1 1/4 inches long, 1 inch wide, skin smooth, grey, brittle; kernel oily and dark brown. A fatty oil is obtained by expression, known officially as gynocardia oil in Britain, as oleum chaulmoograe in the United States.[15]
Fruits are plucked by climbing the tree or using long sticks with a sickle tied to it. The fruits are peeled by knife and the seeds are washed in water and then dried in sun. Seeds are decorticated (dehusked) by mallet, hand hammer, or decorticator. They may also be crushed in an expeller and rotary. The kernels yield 43% oil. The extracted oil is stored in zinc barrels until exported.[6]
Leprosy
Chaulmoogra oil was commonly used in the early 20th century for the treatment of
An ethyl ester of the oil (the "Ball method") was developed by Alice Ball in 1916,[20][21] who died suddenly before publishing the technique. Her work was stolen by Arthur L. Dean who began producing large quantities of the treatment and named it after himself.[22]
It was then produced and marketed by
