My cat ate russian comfrey — FAQ

Is russian comfrey poisonous to cats?

Yes — the ASPCA lists Russian Comfrey (Symphytum uplandicum) as toxic to cats. Symphytum species contain pyrrolizidine alkaloids (PAs), notably echimidine and symphytine, which are hepatotoxic. ASPCA lists Symphytum (comfrey) as toxic to dogs, cats, and horses. Internal use is contraindicated in humans in many countries due to liver toxicity risk. External (topical) use of root preparations is considered lower risk but discouraged on broken skin. Keep pets away from plants.

Russian Comfrey is toxic to cats and reactions can be significant, so treat any ingestion as urgent. Call your vet, or (888) 426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK, straight away rather than waiting to see if symptoms develop.
