The berries are highly poisonous, and the entire plant is considered poisonous to humans. The berries contain cardiogenic toxins which can have an immediate sedative effect on human cardiac muscle tissue, and are the most poisonous part of the plant. Ingestion of the berries can lead to cardiac arrest and death. The berries are harmless to birds, the plant's primary seed dispersers.
