Frequently Asked Questions
Frequently Asked Questions
Is poinsettia really as dangerous as people say?
No. Poinsettia has an exaggerated reputation for toxicity, but it is actually quite mild. The milky sap irritates the mouth and gut, causing vomiting and drooling, but serious poisoning is rare. Still, keep it out of reach and call a vet if symptoms are persistent.
What makes poinsettia irritating to pets?
The milky white sap contains diterpenes that irritate the skin, mouth, and digestive tract. Chewing the leaves or stems releases the sap, causing drooling, vomiting, and sometimes diarrhea. The irritation is usually mild and self-limiting.
What should I do if my pet chews on a poinsettia?
Rinse the mouth with water to remove the sap, wipe any sap off the fur, and offer water. Most cases cause only mild vomiting or drooling that resolves on its own. Call a vet if vomiting is persistent, a large amount was eaten, or your pet seems lethargic.
