The medicinal uses of Henbane date from remote ages; it was well known to the Ancients, being particularly commended by Dioscorides (first century A.D.), who used it to procure sleep and allay pains, and Celsus (same period) and others made use of it for the same purpose, internally and externally, though Pliny declared it to be 'of the nature of wine and therefore offensive to the understanding.'
