Scopolamine

Scopolamine, also known as levo-duboisine and hyoscine, is a tropane alkaloid drug with muscarinic antagonist effects. It is among the secondary metabolites of plants from Solanaceae (nightshade) family of plants, such as henbane, jimson weed, Angel's Trumpets (Datura or Brugmansia), and corkwood (Duboisia). Although scopolamine is sometimes portrayed in the media as a dangerous drug, its anticholinergic properties give it some legitimate medical applications in minute doses. An example is the treatment of motion sickness by use of a transdermal patch.
