Toxicity to pets
All parts of this perennial contain saponins and oxalates which cause severe gastrointestinal irritation. Excessive salivation, vomiting, inappetance/refusal of food, diarrhea, possible tremors, and a drop in blood pressure may occur. The berries are generally not known for being very poisonous, and often may pass through the gastrointestinal tract intact (without being broken down).
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.
