Wilderness Environ Med. 2018 Sep;29(3):411-416. doi: 10.1016/j.wem.2018.05.001. Epub 2018 Jul 4.


We report the case of a patient who presented with respiratory failure, recurrent ventricular fibrillation, ventricular arrhythmias, and hypotension after an intentional ingestion of aconite flowers. Significant ingestion of this plant can produce life-threatening cardio- and neurotoxicity that may require evacuation from the wilderness to a medical facility capable of advanced treatment and intensive care monitoring.

Keywords: aconite; aconitine; cardiotoxins; neurotoxins; ventricular arrhythmias; wolfsbane.
