Jatropha curcas milk contains many toxic substances, such as Crossbones glycoside, blood-sealed throat glycoside, lily of the valley toxin, cucurbitacin glycoside, isoliquiritigenin, maleopicroside and so on. When these toxic juices enter the human body from the wound, it will cause muscle relaxation, blood coagulation, slow heart beating, and finally lead to cardiac arrest and death. If people eat it carelessly, their hearts will stop beating. If milk spills into your eyes, your eyes will go blind at once.

Animals will die within three steps, but meat can still be eaten.
