Jatropha curcas is a species of flowering plant in the spurge family, (Euphorbiaceae), that is native to the American tropics.
Common english names are: physic nut, Barbados nut, poison nut, bubble bush or purging nut.
The seeds contain about 35 % oil, and this Jatropha oil is a high-quality biodiesel fuel, that can be used directly after extraction (i.e. without refining) in standard diesel generators and engines.
The plant can grow in wastelands and grows on almost any terrain, even on gravelly, sandy and saline soils.
