Artemisia dracunculus is a culinary herb known for its aromatic foliage and specific growing requirements.
Yes, tarragon (Artemisia dracunculus) is considered potentially toxic to cats. The herb contains essential oils that can cause gastrointestinal distress if ingested, so it should be kept out of reach of cats.
A cat that has eaten tarragon may show vomiting, diarrhea, and hypersalivation (drooling). Effects are typically mild to moderate; watch for more than one or two bouts of vomiting, persistent diarrhea, or refusal to eat or drink, which signal a need for veterinary attention.
Monitor your cat closely for vomiting, diarrhea, drooling, and reduced appetite. Mild GI signs typically appear within a few hours and resolve within 24–48 hours with supportive care. Call your vet if vomiting or diarrhea continues past a few hours, if your cat refuses food or water for more than 12 hours, or if you notice lethargy or weakness. You can also reach the ASPCA Animal Poison Control Center at (888) 426-4435.
The essential oils present throughout the tarragon plant are responsible for its toxic effect on cats. The ASPCA entry does not single out one part as more dangerous than another, so the whole plant — leaves, stems, and all — should be treated as a hazard.
Yes, tarragon (Artemisia dracunculus) is considered potentially toxic to dogs. It contains essential oils that can cause gastrointestinal distress, so it's best to keep it away from your dog even in small amounts.
The most common signs are vomiting, diarrhea, and abdominal discomfort. You may also notice drooling, decreased appetite, or mild lethargy. Dogs with sensitive stomachs or those that ate a large amount may experience more pronounced or longer-lasting GI signs.
Remove access to any remaining plant and monitor your dog closely. Call your vet if vomiting or diarrhea persists beyond a few hours, if your dog seems weak or dehydrated, or if you notice any neurological signs such as tremors or unsteadiness. You can also reach the ASPCA Animal Poison Control Center at (888) 426-4435.
Onset timing is not specifically documented for tarragon, but for plants with similar essential oils, mild GI signs typically begin within a few hours of ingestion and resolve within 24–48 hours with supportive care.
