Modern Research

Studies confirm Hyoscyamus niger’s antispasmodic, analgesic, and sedative effects, but due to its toxicity, its use in modern herbal medicine is highly restricted.

Henbane remains a historically significant herb but is rarely used today due to its toxic and hallucinogenic properties. Any medicinal application should be handled with extreme caution and professional supervision.
