Abstract

Rhododendron species is one of the largest and most diverse genera in the plant kingdom, comprising over 800 species and existing all over the globe. Grayanotoxin intoxication is caused by ingestion of honey and flowers. Grayanotoxin exists in honey, flowers, pollen, and nectar of the Rhododendron species. Grayanotoxin-intoxicated patients may present with nausea, vomiting, dizziness, weakness, hypotension, bradycardia, and syncope for several hours. We report a case of grayanotoxin intoxication associated with mental changes. A 9-year-old male presented with impaired consciousness and delirium 26 hours after eating about 10 rhododendron sclippenbachii flowers. A brain MRI and EEG were normal. Parenteral fluids were administered and these symptoms resolved completely in 17 hours.
