First Aid & Prevention

First 30 Minutes

  • • Rinse mouth thoroughly with clean water to remove remaining plant residue immediately after ingestion.
  • • Induce vomiting only if explicitly directed by a medical professional or veterinarian for recent large ingestions.
  • • Avoid administering any food, fluids or home remedies unless advised by a healthcare provider.

Contact Vet Immediately

  • • If your pet has ingested more than 1-2 bites of peony plant material, flowers or seeds.
  • • If your pet develops vomiting, diarrhea, abdominal pain or lethargy after exposure.
  • • If you have an equine that has consumed large volumes of peony plant material as part of forage.

Prevention

  • • Keep peony plants out of reach of children, pets and grazing livestock.
  • • Label peony plants clearly in home and community gardens to avoid accidental ingestion.
  • • Regularly remove fallen flowers and seeds from areas accessible to animals and young children.

Treatment & Prognosis

  • • Administer decontamination measures including activated charcoal for recent large ingestions as directed by a professional.
  • • Provide symptomatic care including anti-emetics, fluid therapy and pain relief for gastrointestinal irritation if required.
  • • Monitor exposed patients for 24-48 hours post-exposure to rule out rare secondary complications.

Mechanism of Action

• Irritant compounds including tannins, pyrethrins and monoterpenoid glycosides cause direct irritation of the gastrointestinal mucosa following ingestion.

Other Species Risk (CliniTox)

Information from CliniTox veterinary text.

Ruminant livestock (cattle, sheep, goats): Low toxicity risk; mild gastrointestinal upset is only expected if large volumes of peony plant material are consumed as part of forage.
Small companion mammals (rabbits, guinea pigs, hamsters): No documented toxicity cases, but mild gastrointestinal irritation is possible after ingestion of significant quantities of plant material.
Confusion Risk

The following plants look similar and may be confused:

Other peony species Paeonia spp.
All Paeonia species share very similar visual features (large showy flowers, lobed dark green leaves) and most carry the same low toxicity level as European peony.
