Cicuta maculata is a highly poisonous species of flowering plant in the carrot family known by several common names, including spotted water hemlock, spotted parsley, and spotted cowbane. It is native to nearly all of North America, from northern Canada to southern Mexico.
Cicuta spp. are biennial plants that are all similar in morphology, growing up to a maximum of 2.5 meters (8 ft) in height.The stem of the plant is branching, erect, smooth and hollow (except for partitions at the junction of the leaves and stem), sometimes being purple-striped, or mottled (typically only C. maculata has the purple stripes or spots).
The main distinguishing characteristic of western water hemlock is its toxicity. Cicutoxin is the toxin that is produced, making water hemlock the most poisonous plant in North America. [7] Cicutoxin is a yellowish liquid that is prevalent in the roots. This unsaturated alcohol has a major impact on the central nervous system of animals. Early ...
