Why it's dangerous
Toxicity is caused by triterpene acids which can lead to gastrointestinal irritation and, in severe cases or specific species, hepatic necrosis and liver failure.
Good to know
Toxicity varies by flower color and season; unripe berries are more dangerous than ripe ones. While liver failure is a risk, it is more common in livestock than companion animals.
