Introduction. Water hemlock, which encompasses a range of species divided across two genera (Cicuta and Oenanthe), are regarded as being among the most poisonous plants both in North America and in the United Kingdom. Despite their toxicity, the literature consists almost entirely of case reports. Aim. The aim of this review is to summarize this literature by covering all aspects of taxonomy and botanical characterization, principal toxins, basic pharmacology including mechanisms of toxicity…

Hemlock poisoning is common in horses, sheep, cattle and other livestock, where it can also cause teratogenicity, and it is less common in humans, although some deaths may be misdiagnosed or go unexplained.




Recently, in the city of New Haven, a series of cases of acute poisoning occurred simultaneously and from the same source, and the resulting investigation which determined the cause to be Cicuta prompts me to report these cases briefly, so as to direct attention to the existence of this plant.

The potency in inhibition of the specific binding of the noncompetitive GABA antagonist, [(3)H]EBOB, to GABA-gated Cl(-) channels of GABA receptors in rat brain cortex was found to be correlated with acute toxicity, indicating that the ability to bind to these channels plays an important role in the acute toxicity of these compounds.
