Is Pacific rhododendron toxic to humans?

Pacific rhododendrons contain dangerous levels of a toxin known as Grayanotoxin in all tissues. Physical contact can cause a rash in sensitive people, the pollen can irritate mucus membranes, and ingesting it can cause nausea, vomiting, arrhythmia, low blood pressure, and hallucinations in humans. Children, especially small children, are more vulnerable to severe symptoms. Grayanotoxin is so strong that even the amounts contained in honey made from *Rhododendron* pollen can have negative effects.

Is Pacific rhododendron toxic to cat?

Pacific rhododendron poses a significant toxicity risk to cats. A cat can be poisoned if it mistakenly ingests any part of the plant. Should a cat consume pacific rhododendron, it may display signs of physical discomfort or illness due to poisoning. Cat owners should closely monitor their pets and prevent access to pacific rhododendron to safeguard their well-being. In the event of suspected ingestion, it is imperative to promptly seek veterinary care to ensure the animal receives appropriate treatment.
