J. curcas apart from its use as a biofuel can be put to different uses (Fig. 17.3) (Shanker and Dhyani 2006; Kumar and Sharma 2008). The extract from oil has been used as an insecticide in the control of pests of potato, pulses, and cotton such as cot­ton bollworm (Kaushik and Kumar 2004). The glycerin, a by-product of the trans­esterification process, can be used to make high-quality soap. Press-cake derived from J. curcas can be used as animal and human feed after isolating toxic phorbol esters. The physic nut seed once boiled and roasted is eaten as food in Mexico (Delgado and Parado 1989). Press seed cake can be used as fertilizer owing to its high organic content. Jatropha since ages have found its use in medicine (Dalziel 1955). Seeds are used to treat jaundice, gout, eczema, arthirits, and dermatomucosal diseases. Plant extracts are used to treat cuts, burns, allergies, scabies, leprosy, leco — derma, and small pox. Curcacycline A and some alkaloids such as jatrophine, cur — cain, and jatropham obtained from Jatropha are believed to have antitumor properties (Van den Berg et al. 1995; Thomas et al. 2008) and are used in treatment of HIV and tumor. The roots are reported as an antidote for snake-bites. J. curcas is also used as hedging plant in agricultural fields for protection against damage by livestock.
