Is black cohosh safe for cats and dogs?
Mildly. The ASPCA flags black cohosh 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. All parts of Actaea racemosa contain triterpene glycosides and may cause gastrointestinal upset (vomiting, diarrhoea) if ingested by pets or humans. The ASPCA does not individually list this species, but the Ranunculaceae family is broadly considered irritating. Keep away from pets and children; the rhizome is used medicinally but is toxic in large doses.
| Pet | Toxic? | Per ASPCA |
|---|---|---|
| Cats | Yes (mild) | Mildly toxic to pets |
| Dogs | Yes (mild) | Mildly toxic to pets |

What to do if your pet ate black cohosh
- Remove any plant material from your pet's mouth and move black cohosh out of reach.
- Note how much was eaten and when, and watch for drooling, vomiting, or lethargy.
- Do not induce vomiting unless a vet or poison-control specialist instructs you to.
- Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice.
