Is roman wormwood safe for cats and dogs?
Mildly. The ASPCA flags roman wormwood as mildly toxic to cats and dogs — a chewing pet gets oral irritation and drooling rather than a medical emergency, but it is still worth a high shelf. 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. Artemisia pontica contains thujone and other volatile compounds and is classified in the same genus as tarragon (A. dracunculus), which ASPCA lists as toxic to cats, dogs, and horses (essential oils; vomiting, diarrhea). A. pontica is not individually listed by ASPCA but should be treated as mildly toxic by genus association. The plant also has historic use as an absinthe ingredient, confirming potent biological activity.
| Pet | Toxic? | Per ASPCA |
