Hello Doug, Isabel,
Edible provenances of Jatropha curcas from Veracruz and Quintana Roo States
of Mexico were investigated by Makkar, Becker and Schmook of the University of
Hohenheim and found to be non toxic to humans after roasting. Phorbol esters,
the major toxic constituents of Jatropha, were altogether absent in three of the
seed samples and the contents of trypsin inhibitors, phorbol esters, phytate
were all lower in the roasted nuts, which tasted like roasted peanuts. However,
lectin activity was not reduced by roasting. They concluded that this non-toxic
variety could be cultivated in developing countries for their edible oil, and
seedcake as fodder.
The presence of a new tumor promoter in the seed oil of
Jatropha curcas L has been reported in the Japanese Journal of
Cancer Research by Hirota M, M Suttajit et al from Thailand but there is
not much else besides this singular study. A debate is now on in the new state
of Chattisgarh in India about the advisability of cultivating Jatropha because
of this.
Those interested in Jatropha would do well to visit www.jatropha.de run by the redoubtable
Reinhard Henning (who incidentally, used to post to this list- please see
archives) and The Centre for Jatropha Promotion www.jatrophaworld.com
The former site provides links to Jatropha developments in Egypt, Ethiopia,
Ghana, Madagascar, Mali, Malawi, Namibia, Republique de Cote de Ivoire, Senegal,
South Africa, Sudan, Tanzania, Tunisia and Uganda besides other countries.

Maybe some one there can help here as well.
There are or seem to be two thoughts on the growing of
Physic nut/Jatropha Curcas. One is that the Asian variety has a Carcinogenic
property producing cells in skin tissue from contact with the plant or some
parts thereof. The second is that the type found in Mexico does not have the
above character.
Is this a myth?

Hi Keith
It seems as if you don't think it is a good idea to use Jatropha as a
source to produce bio diesel from?
When I originally posed the question I only received a few messages and
none of them was negative.
Maybe I missed something!
As I originally explained we know nothing about producing bio diesel
and that is why we posted our original questions and gave a brief
explanation why we though it would be best to use jatropha.
We have literally read every article we can find about producing bio
diesel and to date have not found in our opinion any crop better
suited for us to produce bio diesel from, as a matter fact it seems from
what we have read that jatropha is the number one choice world wide to
produce bio diesel from.
You obviously have a lot of experience & knowledge regarding
producing bio diesel as well as what to use to do so. Therefore If you
believe jatropha is not the way to go it would be greatly appreciated if you
would say so & why you think so, because as I have said before we
are asking for advice and if you have reasons to
believe that jatropha is unsuitable I would like to know about
them so as to enable us to make a fully enlightened decision.
Kind regards.
Isabel.
