Aconitum (), commonly known as aconite, monkshood, wolf's bane, leopard's bane, mousebane, women's bane, devil's helmet, queen of 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, growing in the moisture-retentive but well-draining soils of mountain meadows. Most species are extremely poisonous and must be dealt with very carefully.
