Biofuel originally comes from the sun captured through photosynthesis by the plants used as feedstock for biofuel production and stored in the plants' cells. Various plants and plant derived materials are used for biofuel manufacturing. One of the plants that have been considered among the most promising for production of biofuel is Jatropha curcas. These and many other organic materials are more sustainable than petroleum, meaning they can be regrown and remain productive with less negative impact on our ecosystem. Present paper deals with general information and other uses about this miraculous, multipurpose, commercially significant large shrub. It is one of the commonly occurring species in India and locally known as Ratanjyot or Jangli erandi. The harvested Jatropha seeds are used for production of Jatropha oil and biodiesel. The Jatropha oil can be used directly as a liquid fuel in older diesel motors, in generators and pumps running at a constant speed or in newer engines with small modifications in the fuel system. The Jatropha oil can also be mixed with fossil diesel before use in the engine, which combines the properties of the fossil fuel with the lower environmental impact of the vegetable oil (Achten, 2008; Siddharth, 2009).
