Where does Abrin come from?

Explanation:
Abrin is a toxin produced by the plant Abrus precatorius, the rosary pea (jequirity bean). The dangerous compound is concentrated in the seeds, and chewing or crushing them releases abrin, which is a potent ribosome-inactivating protein that halts protein synthesis and leads to cell death. It is not from tobacco leaves (which contain nicotine), nor from castor beans (which contain ricin), nor from bacteria. So the source is the seeds of the rosary pea plant.
