Is Boneset toxic to dogs?

Eupatorium perfoliatum

Toxic to dogs

Yes — boneset is toxic to dogs according to the ASPCA. Keep it well away from any dog that chews plants; reactions can be significant. This classification follows the ASPCA Toxic and Non-Toxic Plant List. Boneset is not individually listed by the ASPCA, but laboratory analyses confirm it contains hepatotoxic pyrrolizidine alkaloids (lycopsamine, intermedine and derivatives) in all parts. Because these alkaloids can cause cumulative liver damage, it should be treated as toxic and kept away from cats, dogs and livestock; signs of plant ingestion include vomiting, lethargy and gastrointestinal upset. Verify any concern with a vet.

What to do if your dog ate boneset

  1. Remove any plant material from your dog's mouth and move boneset out of reach.
  2. Note how much was eaten and when, and watch for drooling, vomiting, or lethargy.
  3. Do not induce vomiting unless a vet or poison-control specialist instructs you to.
  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice.
  5. Bring a leaf or photo of boneset to the appointment so it can be treated correctly.

General guidance, not veterinary advice. If you think your dog has eaten boneset, contact your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 — do not wait for symptoms to worsen.
