Rosary Pea
Abrus precatorius
Rosary Pea (Abrus precatorius), also known as Jequirity Bean, is one of the most acutely toxic plants on earth. Its seeds contain abrin — a ribosome-inactivating protein (RIP) closely related to ricin — that is lethal in nanogram quantities. The hard seed coat usually prevents toxicity if seeds are swallowed whole, but chewed or cracked seeds are life-threatening.
Important Notes
Toxic compounds: abrin (ribosome-inactivating protein) in seeds; leaves contain abrine alkaloid
Mechanism: abrin halts protein synthesis in cells by inactivating ribosomes; affected cells die; organs fail progressively
Symptoms (delayed 2–6h): vomiting, diarrhea, weakness, abdominal pain; severe cases cause multi-organ failure, seizures, and death
Intact swallowed seeds may pass without harm; cracked or chewed seeds are a medical emergency
Any suspected abrin exposure is a veterinary emergency — do not wait for symptoms
