Hyoscyamus niger
Henbane can be toxic, even fatal, to animals in low doses. Its name dates at least to 1265. The origins of the word are unclear but "hen" probably originally meant death rather than referring to chickens. Hyoscyamine, scopolamine, and other tropane alkaloids have been found in the foliage and seeds of the plant. Common effects of henbane ingestion in humans include hallucinations, dilated pupils, restlessness, and flushed skin. Less common symptoms such as tachycardia, convulsions, vomiting, hypertension, hyperpyrexia and ataxia have all been noted.
