[Intoxication with Monkshood (Aconitum napellus)].
Three patients presented with an intoxication caused by Aconitum napellus, commonly known as Aconite, Monkshood or Wolfsbane. The first patient, a woman aged 24, was resuscitated after accidental ingestion of plant material 'from nature'. She experienced severe ventricular tachyarrhythmias. After discharge she returned with identical symptoms, which were now interpreted as intentional intoxication in a suicide attempt. She was referred to the Psychiatry department. The second patient was a 2-year-old boy who had cutaneous exposure to Aconite. Except for some red spots around his mouth there were no other symptoms. The third patient was a 34-year-old woman who ate Monkshood, which she mistook for parsley. Alarmed by the bitter taste she contacted the hospital. She was treated with stomach lavage which removed most of the ingested plant material, and with activated charcoal. She had no symptoms during observation in the hospital. Aconite alkaloids are known to cause ventricular arrhythmia by a prolonged activation of sodium channels. Because there is no antidote, treatment is largely supportive but serious arrhythmias and respiratory arrest need to be anticipated.
