White Snakeroot, Ageratina altissima, is a common plant found in the woodlands of eastern North America. In the past white snakeroot was often ingested by dairy cattle which caused a toxic compound called tremetol to be excreted in their milk. If this milk was then consumed by a person, they could be poisoned and develop milk sickness. I discuss why this was a problem in the past and why you never hear about it today, even though white snakeroot is an incredibly common plant in many places.
