First Aid & Prevention

First 30 Minutes

  • • Remove all remaining plant material from the exposed individual/pet's mouth immediately
  • • Rinse the mouth thoroughly with cool clean water to reduce irritation
  • • Do not induce vomiting unless explicitly instructed by a medical/veterinary professional

Contact Vet Immediately

  • • Persistent oral pain, swelling or excessive drooling after rinsing
  • • Observation of vomiting, diarrhea, difficulty breathing or swallowing
  • • Suspected ingestion of a large quantity of the plant, or presence of neurological symptoms (seizures, unsteady gait)

Prevention

  • • Keep the plant out of reach of children, cats, dogs and other domestic animals
  • • Wear gloves when handling the plant to avoid skin irritation from sap
  • • Label the plant clearly if kept in shared spaces to prevent accidental ingestion

Treatment & Prognosis

  • • Administer appropriate decontamination followed by symptomatic supportive care
  • • Provide analgesics for pain, antihistamines or glucocorticoids to reduce severe swelling
  • • Deliver calcium supplementation for very large ingestions, and support liver/kidney/heart function as needed
