Background <p>Mad honey is a type of honey with hallucinogenic properties found in the Himalayas of Nepal. It is used by locals for its supposedly medical and recreational properties. It contains a toxin named ‘Grayanotoxin’ which is mainly derived from the nectar of few <i>Rhododendron</i> species native to Himalayas.</p> Case presentation <p>This is a case report of 38-year-old male who presented to emergency department of our center with dizziness, three hours following ingestion of mad honey. He had heart rate of 45 beats per minute. Electrocardiogram showed bradycardia without any other abnormality. He was managed conservatively in coronary care unit for 48 h without any complication.</p> Clinical discussion <p>“Grayanotoxin” is a neurotoxin that acts on voltage-gated sodium channels, preventing their inactivation and causing persistent depolarization, leading to a wide range of symptoms. Management is symptomatic as no antidotes are available till date. Early recognition prevents unnecessary investigations and interventions.</p> Conclusion <p>Mad honey poisoning should always be considered in patient particularly those living in endemic areas presenting with unexplained dizziness and bradycardia. Most of these cases respond well to supportive therapy emphasizing the importance of early recognition and close clinical observation.</p>
