White Snakeroot

Eupatorium perfoliatum Also boneset and
thoroughwort. This is invasive in my wildflower gardens and
I have been pulling it out for the better part of 3 weeks. It is
poisonous to animals especially cows where this can be significant
because it can cause milk sickness in humans. In cows a mild
case is called the trembles and results in trembling of the muzzle
and legs. In humans who drank the milk of affected cows
milk sickness claimed the lives of thousands in the early 1800's,
the most famous of which was Abraham Lincoln's mother. The toxin
is a fat soluble alcohol named tremetol.
