“Water hemlock (Cicuta) is a genus of highly poisonous perennial plants in the carrot family, considered North America's most toxic plant, growing in wet areas and featuring white, umbrella-shaped flowers and finely toothed leaves. All parts are toxic, especially the roots, which contain a potent convulsant (cicutoxin) that can be fatal to humans and livestock, causing violent seizures. It is often mistaken for edible plants like parsnips, making correct identification crucial.”
