PlantFunMountain Fetter-bush Toxic?
All parts of the plant are toxic, containing potent grayanotoxins that disrupt cardiac and nervous system function
The plant is highly toxic to most mammals and extremely toxic to birds, with symptoms onset within 6 hours of ingestion
Ingestion can lead to fatal complications including cardiac arrhythmia, respiratory depression, and aspiration pneumonia

Toxicity Snapshot
First Aid & Prevention
First 30 Minutes
- • Induce vomiting only if the affected individual/animal is fully conscious and not experiencing seizures
- • Rinse out the mouth thoroughly with clean water
- • Collect a sample of the ingested plant for accurate identification
- • Avoid administering any food or medication unless explicitly directed by a healthcare provider/veterinarian
Contact Vet Immediately
- • Any confirmed or suspected ingestion of Pieris floribunda
- • Presence of symptoms including excessive drooling, vomiting, abdominal pain, or abnormal heart rate
- • Onset of seizures, respiratory distress, weakness, or collapse
Prevention
- • Do not plant this species in yards accessible to children, pets, or grazing livestock
- • Fence off wild growing areas of the plant to prevent access by livestock and companion animals
- • Properly identify all landscape and wild plants to avoid accidental exposure to toxic species
Treatment & Prognosis
- • Perform decontamination via induced emesis and activated charcoal administration for recent ingestion events
- • Provide symptomatic care including analgesics for pain and antibiotics to prevent or treat aspiration pneumonia
- • Administer intravenous 20% lipid emulsion at 1.5 ml/kg over 5 minutes as clinically indicated
- • Use atropine to treat clinically significant bradycardia, provide supportive care for cardiac and respiratory dysfunction
Professional Toxicology
• Grayanotoxins bind to and modify voltage-gated sodium channels in nerve and muscle cells, prolonging membrane depolarization
• Disruption of normal electrical signaling impairs cardiac, respiratory, and neuromuscular system function leading to toxic symptoms
