Toxic
Dr. Saturnina Halos, chairman of the Department of Agriculture's Biotechnology Advisory Team, said in a forum on biofuels that jatropha contains neurotoxins capable of killing humans and animals. So far, there are two known cases of poisoning. In 2007, 21 grade school students in the island village of Tubigon, Bohol were rushed to hospital after they ate the fruit of the tuba-tuba, jatropha's local name. Another case of poisoning happened in Cansilayan, Murcia, Negros Occidental, where 10 children ate jatropha seeds.
