Poisonous Management

Toxic parts

Whole plant especially the seeds [4][5]


Jatrophin (curcin), a toxalbumin causing bleeding lesions in the mouth, oesophagus, stomach, and intestine. Jatrophin (curcin), is also a violent purgative that stimulates bowel movement. The poison kills by interfering with the synthesis of protein in intestinal wall cells. [2][6]

Risk management

This plant should be kept out of reach of children. The attractive seeds could tempt toddlers into consuming it. [5]

Poisonous clinical findings

The symptoms of poisoning is similar to those of J. curcas due to the same toxin i.e. jatrophin.

The reaction time is between 15 to 20 minutes. There is difficulty in breathing, sore throat, bloating, dizziness, vomiting, diarrhoea, drowsiness, dysuria, and leg cramps. The abdominal symptoms of intense pain, nausea, vomiting, and diarrhoea may appear within an hour after ingestion. These symptoms had been attributed to the presence of cucanoleic acid in the oil.  In severe poisoning, muscular spasms and collapse may ensue and may even be fatal. Childrean are especially vulnerable because of the pleasant-tasting seeds. [2][6]


There is no known antidote for jatrophin. Treatment is directed towards symptomatic relieve and correction of fluid and electrolyte balance.

Gastric lavage is done in the absence of profuse vomiting. Treated with bismuth subcarbonate and magnesium trisilicate to protect the stomach. [2][6]
