Toxicity of Henbane

Is Henbane toxic to humans?

Henbane is extremely poisonous when consumed and may lead to fatal outcomes. Additionally, it can irritate the skin upon direct contact. Every part of this plant contains high levels of toxicity. Symptoms indicative of poisoning include excessive drooling, headaches, nausea, vomiting, diarrhea, an abnormal increase in heart rate, unconsciousness, and seizures. The plant bears no resemblance to any widely consumed food plants, thus the likelihood of accidental ingestion is low. Children are the demographic most vulnerable to henbane poisoning, as it is a prevalent weed often found in grasslands, pastures, and along roadways.
