Anand,
Thanks for clarifying this. This is exactly how I did the J-nut
burn. I did not open the "capsules" -- they were burned together with
the seed, so there was hopefully very little exposure to the toxic oils
inside. (They would likely have been volatalized within the shell in the
heat and made their was through the shell to be burned as vapour/gas in
the flame.)

(This is a photo of the Jatropha nuts (J-nuts) both before and after
running through my TLUD stove. After carbonizing, you can see that the
seedpods shrink somewhat, but are essentially intact. ~ note: I was a
little concerned at first that if I did not crack open the seedpods that
they might 'pop' like popcorn... That didn't happen, luckily. ;-)
