Background
- Black hellebore (Helleborus niger, Helleborus nigra) is a perennial plant, native to Central and Southern Europe, Greece, and Asia Minor, and is cultivated largely in the United States as a garden plant. Black hellebore is not the same as false hellebore, American hellebore, white hellebore, or other Veratrum species.
- Black hellebore is a poisonous plant that is toxic when taken in even small-to-moderate doses and should not be used without the supervision of a medical professional. It was formerly used for palsy, insanity, dropsy, and epilepsy but is seldom currently used for these or any other uses.
