Is white comfrey safe for cats and dogs?
Use caution. White Comfrey is on the mildly-toxic side of the ASPCA list. Most ingestions are short-lived but unpleasant for the pet; the cost-free fix is a placement they can't reach. This classification follows the ASPCA Toxic and Non-Toxic Plant List, the most widely used reference for companion-animal plant safety in the US and the standard most UK vets cite as well. Like all Symphytum species, Symphytum orientale contains pyrrolizidine alkaloids (PAs), compounds known to be hepatotoxic with repeated ingestion. Not individually listed by ASPCA, but given the genus-wide PA content, ingestion by pets or children should be avoided. Bristly leaf hairs may cause mild contact dermatitis. Not recommended for medicinal use or consumption.
