White Snakeroot

(Eupatorium rugosum Hout.)
(formerly known as Eupatorium urticaefolium)

Toxic principle

• The apparent toxic principle in white snakeroot has been given the trivial name tremetol. It has been described as a fat-soluble, high molecular weight alcohol.
• Crude tremetol, was later shown to be separable into a toxic ketone fraction (61%) (tested in goldfish) and a nontoxic sterol fraction (39%). The ketone fraction was later separated into tremetone, dihydrotremetone, and hydroxytremetone. These may all be components of a fragile tremetol molecule.
