This plant has been mentioned as causing poisoning in humans and animals, but case reports have not been found. The plant juice can cause dermatitis in sensitive individuals. glycoside, iridin (or irisin), has been implicated as the toxic compound in iris species, although this has not been confirmed (Fyles 1920, Cooper and Johnson 1984).
Both the berries and the entire plant are 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.
