Atropine
Atropine is a tropane alkaloid, that can be extracted from the deadly nightshade (Atropa belladonna), mandrake (Mandragora officinarum) and certain other plants. It is mainly used as a drug.  Atropine can be deadly.  The substance derives its name from Atropos, one of the three Fates. In Greek mythology, the Fates chose how a person was to die. Atropine is a core medicine in the World Health Organization's "Essential Drugs List", which is a list of minimum medical needs for a basic health care system.
