Grayanotoxin poisoning is most commonly seen in the East Black Sea Region of Turkey due to consumption of mad honey, which is made by bees from the flowers of the rhododendron plant. Mad honey poisoning is dose dependent. In low doses, it causes dizziness, hypotension and bradycardia. In high doses, it can cause unconsciousness, seizures and atrioventricular blocks. Local people are well aware of mad honey poisoning and generally do not go to the hospital for mild symptoms. In clinical practice, patients with mad honey poisoning are kept under coronary intensive care observation for at least 12-24 hours. As seen in this case report as well as in some publications in the literature, stable patients who respond to atropine and fluid therapy may not need to be hospitalized. In this case report, we present a patient with sinus bradycardia due to mad honey poisoning from the East Black Sea Region of Turkey, who responded to intravenous fluid and atropine treatment in a short time.
