Is pierre's stephania safe for cats and dogs?
Toxic — the ASPCA lists pierre's stephania as a clear no for cats and dogs. The painful part for the pet is usually quick and intense; the right move is to keep it out of any room a pet roams unsupervised. 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. Stephania pierrei, like other Stephania species, belongs to Menispermaceae and contains isoquinoline alkaloids (bisbenzylisoquinolines and related compounds) that are pharmacologically active and potentially toxic to pets and humans if plant material is ingested. The species is not individually listed by ASPCA; caution is warranted based on genus-level alkaloid profiles. Keep away from pets and children.
