Is Common wormwood toxic to pets?
Common wormwood is toxic to pets if ingested in large quantities. The plant contains essential oils such as thujone, which can cause severe gastrointestinal irritation, vomiting, diarrhea, central nervous system stimulation, tremors, and in severe cases, seizures or organ damage. Animals typically avoid grazing on it due to its strong bitter taste, but potted or accessible garden specimens should be kept well away from cats, dogs, and horses to prevent accidental poisoning.
