During the holidays, Poinsettias are a popular Christmas plant. Though they have a bad rap, poinsettia (Euphorbia pulcherrima) plants are only mildly toxic to cats and dogs. The milky white sap found in poinsettias contains chemicals called diterpenoid euphorbol esters and saponin-like detergents. While poinsettias are commonly “hyped” as poisonous plants, they rarely are, and the poisoning is greatly exaggerated. When ingested, mild signs of vomiting, drooling, or rarely, diarrhea may be seen. If the milky sap is exposed to skin, dermal irritation (including redness, swelling, and itchiness) may develop. Rarely, eye exposure can result in a mild conjunctivitis (“pink eye” secondary to inflammation). Signs are self-limiting and generally don’t require medical treatment unless severe. There is no antidote for poinsettia poisoning. That said, due to the low level of toxicity seen with poinsettia ingestion, medical treatment is rarely necessary unless clinical signs are severe.

Poison type: Plants
