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).
