Water hemlock is a highly toxic plant belonging to the Apiaceae family. It typically grows in wet areas, such as marshes and along riverbanks, and can reach heights of up to 1.5 meters. The plant features small white flowers arranged in umbrella-like clusters and has a distinctive, thick, tuberous root. All parts of water hemlock contain potent alkaloids, particularly cicuta, which can cause severe poisoning if ingested. Symptoms may include seizures, respiratory failure, and, in extreme cases, death. Due to its toxicity, water hemlock is often confused with edible plants, making it crucial to identify it accurately in the wild.
