Acute dietary poisoning by white hellebore (Veratrum album L.). Clinical and analytical data. A propos of 5 cases

Abstract

Five cases of acute accidental poisoning with White Hellebore are reported. All cases occurred several minutes after the ingestion of home-made gentian wine. The clinical signs were nausea, vomiting, abdominal pain, hypotension and bradycardia. The initial ECG showed sinus bradycardia in 4 cases. In one patient, complete atrioventricular block with an ectopic atrial bradycardia and an intermittent idioventricular rhythm was recorded. Symptomatic treatment and/or atropine led to recovery within a few hours. These symptoms suggested poisoning with a veratrum alkaloid. The White Hellebore (Veratrum Album L.) and the Yellow Gentian (Gentiana Lutea L.) often grow side by side in the fields; it is easy to confuse the two plants before they flower if one is not a botanist. Each gentian wine was analysed by thin layer chromatography and chemical ionisation spectrometry. All the wines contained Veratrum alkaloids.
