Poisonous
From wikipedia:
Characteristic of many members of the family Euphorbiaceae, Jatropha plants contain several toxic compounds, including lectin, saponin, carcinogenic phorbol, and a trypsin inhibitor. Despite this, the seeds are occasionally eaten after roasting, which reduces some of the toxicity. Its sap is a skin irritant, and ingesting as few as three untreated seeds can be fatal to humans.
And the plant is BANNED in Australia. Possibly not the best choice?
