Is common centaury safe for cats and dogs?
Not entirely — common centaury is mildly toxic to cats and dogs. It rarely causes serious harm, but chewing it triggers real discomfort, so keep it out of a pet's 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. Centaurium erythraea is not listed on the ASPCA Toxic and Non-Toxic Plant database. As a gentian-family bitter herb it contains secoiridoid glycosides (amarogentin-related compounds); these are recognised as bitter digestive stimulants in humans and are considered low toxicity, but no specific veterinary safety clearance exists. Classified as mildly-toxic as a precaution; consult a vet if a pet ingests large quantities.
