Is Round-leafed Stephania toxic to dogs?

Stephania rotunda

Toxic to dogs

Yes — round-leafed stephania 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. Stephania rotunda contains pharmacologically potent isoquinoline alkaloids (including l-tetrahydropalmatine and cepharanthine) used in traditional medicine and pharmaceutical research. These alkaloids are toxic to animals and humans in uncontrolled doses. The genus is not individually listed by ASPCA, but due to confirmed alkaloid toxicity, the plant should be kept away from pets and children.

What to do if your dog ate round-leafed stephania

  1. Remove any plant material from your dog's mouth and move round-leafed stephania 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 round-leafed stephania to the appointment so it can be treated correctly.
