Quick Answer
Water hemlock poisoning symptoms include nausea, vomiting, abdominal pain, diarrhea, and seizures. In severe cases, it can lead to respiratory failure, cardiac arrest, and death. The poison is highly toxic and can be fatal in small amounts.
Recognizing Symptoms
Water hemlock poisoning symptoms typically begin within 15 minutes to an hour after ingestion. The initial symptoms may include nausea, vomiting, and abdominal pain. Diarrhea and seizures may follow, and in severe cases, the patient may experience respiratory failure and cardiac arrest. If you suspect someone has ingested water hemlock, call emergency services immediately.
Medical Treatment
There is no antidote for water hemlock poisoning, but prompt medical treatment may increase the chances of survival. Activated charcoal can be administered to help absorb the toxin, and supportive care, such as oxygen therapy and cardiac monitoring, may be necessary. In severe cases, patients may require hospitalization and intensive care, including mechanical ventilation and dialysis.
Prevention and Identification
To avoid water hemlock poisoning, it’s essential to identify the plant correctly. Water hemlock (Cicuta maculata) has a distinctive, unpleasant odor and a hollow stem. It can be found growing in wet areas, such as along streams or in marshes. Ingestion of any part of the plant, including the roots, leaves, or stems, can be fatal. If you plan to forage for wild plants, it’s crucial to consult with an expert and exercise extreme caution.
