Poison Hemlock is a deadly plant
that grows around water sources. It’s a
killer.
Poison Hemlock is a plant that I have never paid much
attention to. It didn’t rank very high
on my “need to know” list. Recently, a seminar
speaker discussed poison hemlock and its effects. That caused me do a bit of investigation in
my home state of Oregon.

The Oregon Department of Agriculture’s web site states:
“Juice from the poison hemlock taproot and its crown are extremely
poisonous….. It has also accidentally poisoned many who have mistaken it for
parsley. Poison hemlock is considered to be one of the most poisonous plants in
North America, and is often mistaken for water-parsnip or other edible members
of this family.”

My other online resource (Encyclopedia Britannica) for further states:
“The toxic alkaloid coniine, present throughout the plant,
causes paralysis, loss of speech and depressed respiratory function with
eventual asphyxia if gone untreated. Surprisingly, the mind remains unaffected
until death.”
My recommendation:
Keep your hands off don’t touch it at all. Don’t let anyone in your party put any part
of poison hemlock in their mouth (as a young boy would put a piece of straw in
his mouth.)
The attached video (below) is from the University of Wisconsin. It gets a bit technical but it does a wonderful job of identifying this toxic plant.
