Aconitum
Aconitum (/ˌækəˈnaɪtəm/),[2] also known as aconite, monkshood, wolf's bane, leopard's bane, mousebane, women's bane, devil's helmet, Queen of all Poisons, or blue rocket, is a genus of over 250 species of flowering plants belonging to the family Ranunculaceae. These herbaceous perennial plants are chiefly native to the mountainous parts of the northern hemisphere,[3] growing in the moisture-retentive but well-draining soils of mountain meadows. Most species are extremely poisonous[4] and must be dealt with carefully.
