What is Water Hemlock?
Water hemlock is considered to be the most poisonous plant growing in North America. All parts of the water hemlock are toxic and can cause death in as little as 15 minutes.
Water hemlock grows in marshy, swampy areas of meadows; and along banks of streams, pools, and rivers. Accidental poisonings usually occur when water hemlock is mistaken for edible plants such as artichokes, celery, sweet potatoes, sweet anise, or wild parsnip.
Even though water hemlock is extremely poisonous, it is used as a medicine for migraine headaches
, painful menstruation
, and worms in the intestines
