Hemlock water dropwort poisoning - a review

Abstract

Hemlock water dropwort (Oenanthe crocata) is probably the most poisonous plant in the British Isles. The roots are the most toxic part of the plant and have been eaten in mistake for the roots of several other plant species with often fatal results. A recent nonfatal case of poisoning is reported and previous cases reviewed. Present evidence suggests that barbiturates, particularly short-acting agents are life saving and are the drugs of choice in the treatment of the convulsions.
