1. Poisoning in sheep and cattle which have fed on white snakeroot or some other poisonous plants.

Affected animals tremble and become weak.

2. An intoxication of cattle, caused by eating white snakeroot, Eupatorium urticaefolium, or the rayless goldenrod.

The active agent is a higher alcohol, tremetol, which intoxicated cows eliminate in their milk, causing milk sickness when ingested by humans.
