Water Hemlock Flower Bloom
It is native to nearly all of North America, from northern Canada to southern Mexico.
The chief poison is cicutoxin. The plant is occasionally mistaken for parsnips, due to its clusters of white tuberous roots; this is an often fatal error, as the Cicuta is extremely poisonous. Indeed, spotted water hemlock is considered to be North America’s most toxic plant.
Poisoning Symptoms include:
Cicutoxin, an unsaturated aliphatic alcohol that is most concentrated in the roots. Upon consumption, nausea, vomiting, and tremors occur within 30–60 minutes, followed by severe cramps, projectile vomiting, and convulsions. There are occasional long-term effects, like retrograde amnesia.Ingestion of water hemlock in any quantity can result in death or permanent neurological damage of the central nervous system.
