Jatropha originally comes from Central America. However, jatrophas have become naturalized in many different subtropical and tropical regions of the planet, such as India, North America and Africa.

Biodiesel and Oil

The oil that is extracted from the seeds of Jatropha curcas is used for the production of biodiesel fuels in both Brazil and the Philippines. In those areas, jatropha curcas is cultivated naturally (as in parts of Africa and India). One prominent train line in India runs partially on biodiesel fuel.


Similar to various plants from the Euphorbiaceae family, Jatropha plants consists of some different toxic compounds, including saponin, a trypsin inhibitor, lectin and carcinogenic phorbol. However, Jatropha plants are still occasionally eaten after roasting, which is a process that decreases some of its toxicity. It is considered to be fatal to eat.

Intercropping is a process that aims to make a higher yield on a certain area of land by using its resources to produce more than a single crop.
