This Article: The Truth About Monkshood - a deadly beauty in the forest. Friend or foe?

Family: Ranunculaceæ (Crowfoot)
Name: Acontum Delphinifolia (Monkshood - also called Wolfbane)

monkshood

          Aconite is perhaps the most deadly poison on Earth. The genus Aconitum is the source of that poison, and occurs in all species. The genus is found throughout the northern hemisphere, with one species and three subspecies in Alaska. They are identified by their leaf shapes, and number and location of their flowers. Pictured here is the most abundant subspecies (Aconitium delphinifolia d.) which is found throughout most of the state.
          The second species (Aconitium maximum) is found in the Aleutian Islands and eastern Asia with related forms across northern Europe. It inhabits sub-alpine regions. Maximum has large leaves that are dense and all flowers are clustered at the top of the leafy stalk.
          All parts of all species are poisonous and the roots contain the most aconite making it extremely deadly. The genus Maximum carries more poison than any of our other monkshoods. Even handling the root is dangerous, and if it enters the blood stream through a cut or abrasion it can cause death within minutes.

          The "wolfbane" poison of Europe and Asia was merely the liquid extracted from the root of monkshood, which was dribbled onto bait to kill wolves. It was very effective. Harpoons tipped with concentrated aconite have been used to kill whales in the Aleutian Islands and Kamchatka Peninsula. Ounce for ounce it is far more deadly than the venom of any reptile and can kill quicker.
          There are herbal medicines made from the subspecies, delphinifolia, that are used by some herbalists. The practice is dangerous and should be avoided. Even collecting it is dangerous.
