Cardiovascular effects of poisoning following ingestion of dried Rhododendron flower in a middle-aged woman: a case report

Abstract

Rhododendron toxicity can be life-threatening or fatal when manifested with cardiovascular and neurological adverse effects. A 56-year-old woman presented with dizziness, chest tightness, shortness of breath, and a tingling sensation in her face and limbs after ingestion of dried flowers of Rhododendron. On examination, she had sinus bradycardia and hypotension. She was admitted for monitoring and observation. She was managed with intravenous crystalloids, noradrenaline infusion, and atropine. Her vital parameters were normalised and was discharged after 24 hours. These symptoms were most likely due to grayanotoxin found in the Rhododendron species. This case highlights the need to raise awareness on the risks of plant poisoning due to rhododendrons and to seek timely medical care in case of symptoms. Clinicians are recommended to take context-specific history to identify potential aetiologies of poisoning.
