Black Henbane

Hyoscyamus niger, commonly known as black henbane, is a traditional medicinal plant found in Europe, Asia, and North Africa. It has not been extensively used in traditional medicine practices, though it has historical significance due to its potent antispasmodic properties. Scientific evidence suggests that Hyoscyamus niger can be effective in reducing cough and shortness of breath when combined with propolis in hospitalized COVID-19 patients; however, the overall body of research is limited. Studies have also shown that blue LED light combined with 4 mg/L glycine leads to higher atropine accumulation, while red LED light with 8 mg/L glycine results in higher scopolamine levels in callus cultures of Hyoscyamus niger. Henbane poisoning, particularly in children, can present with antimuscarinic symptoms such as agitation and mydriasis; severe cases may include seizures and acute kidney injury. Safety concerns are minimal based on current data, but the plant is highly toxic due to its atropine and scopolamine content. There have been no recorded major issues or drug interactions reported in the literature, though use should be approached with extreme caution given its potent nature.
