Claims and Facts Jatropha Curcas

It has become clear that the positive claims on J. curcas are numerous, but that only few of them can be scientifically sustained (Daey Ouwens et al., 2007). The claims hat have led to the popularity of the crop, are based on the incorrect combination of positive characteristics, which are not necessarily present in all J. curcas accessions, and have certainly not been proven beyond doubt in combination with its oil production. Hard figures and verifiable data on various aspects of J. curcas remain scarce, and here, the latest and most important scientifically sound information is included.
