What makes it toxic

Sesquiterpene lactones and pyrethrin-related compounds in the foliage that mildly irritate the gut and skin.

Common questions

Can feverfew help my dog’s arthritis like it does migraines in people?

Do not self-dose. Herbal medicine in dogs needs veterinary dosing, and raw feverfew is irritant rather than therapeutic.

Why did my dog drool after chewing feverfew?

The lactones irritate the mouth directly. Rinse with water and the drooling should stop once the taste fades.
