The Deadliest Plant In North America

In 1992, a 23-year-old man and his 39-year-old brother were foraging for wild ginseng in Maine.  The younger brother harvested several plants from a swampy area and took three bites from the root of one plant.  The older brother took one bite from the same root.

Within three hours, the younger brother died.  The older brother lived, though not without experiencing seizures and delirium.

The offending plant, of course, was not wild ginseng.  It was water hemlock (Cicuta maculata). 

Water hemlock is considered the most toxic plant in North America.  Some sources even consider water hemlock to be the most toxic plant in the Northern Hemisphere.

As it turns out, water hemlock is not a single species.  Water hemlock represents multiple species that all contain a potent toxin.  This toxin disrupts the central nervous system and can lead to death if prompt treatment isn’t given.

I recently spent some time in the presence of two water hemlock species.  If you’re interested in learning how to identify these deadly plants, check out the new video!

Thanks for reading and watching, and thank you for your continued support!
