dc.description.abstractBOTANICAL DESCRIPTION: General: A large-leafed, robust annual weed. The most characteristic feature is its hardened spiny fruit capsules, which contain a very large number of small black compressed kidney-shaped seeds.en
dc.description.abstractTOXIC PRINCIPLE: The seeds are the most poisonous part of D. stramonium and contain the alkaloids atropine and hyoscine.en
