What is Jatropha?
Jatropha is a genus of plants, trees, and shrubs native to South America and the Caribbean. An estimated 175 species are placed in this genus. There are a number of uses for Jatropha, ranging from compounds which can be used as vegetable dyes to oils which can be utilized in the production of biofuels. Some alternative fuel advocates have championed Jatropha as a source of potential biodiesel, although there is some evidence to suggest that there are better alternatives. These plants are in the family Euphorbiaceae. Like other plants in this family, they contain a number of compounds which are toxic, along with a sticky, milk white sap which acts as a skin irritant. Members of the Jatropha genus also have extremely toxic seeds; it only takes three to kill a full-grown adult. Despite the toxicity, some cultures have used parts of Jatropha species in traditional medicine and cooking, and research indicates that some species may contain compounds which are useful medicinally.

Family: Euphorbiaceae Synonyms: Curcas purgans Jatropha curcus is a drought-resistant perennial variety of castor, which grows well in marginal/poor soil. It is easy to establish, grows relatively fast and survives for 50 years. It is wild in nature and propagates easily at any place, climate and temperature conditions. Jatropha grows wild in many areas of India and can thrive on infertile soil. A good crop of Jatropha can be obtained with little effort. Production of seeds usually takes place within 2 to 5 years depending on the soil quality and rainfall. Jatropha seeds consist of about 60 percent oil; which can be transformed into bio-diesel fuel through the process of esterification. The oil can be combusted as fuel without being refined. It burns with clear smoke-free flame. It has also been tested successfully as fuel for simple diesel engine. The by-products are press cake, which are a good source of organic fertilizer. The oil also contains insecticide. Medically it is used for
