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.
Some people apply water hemlock directly to the skin for redness and swelling (inflammation).
