Ricinus, seed, African Wonder tree, Euphorbiaceae
Toxicity to pets
This plant (Ricinus sp.) contains a highly toxic glycoprotein called ricin and ricicine, an alkaloid found in both the seeds and leaves. Ricin is a glycoprotein that prevents protein synthesis; when ingested, clinical signs of inappetance, drooling, abdominal pain, vomiting, severe bloody diarrhea, abdominal straining, weakness, trembling, hypotension (drop in blood pressure), and sudden collapse may be seen. This plant has a very narrow margin of safety; only a small amount ingested can result in severe poisoning. Death can occur with even a very small ingestion of the beans.
The content of this page is not veterinary advice. A number of factors (amount of substance ingested, size of the animal, allergies, etc.) determine what is toxic to a particular pet. If you think your pet has eaten something potentially toxic, call Pet Poison Helpline or seek immediate veterinary treatment.
