Belladonna or Deadly Nightshade is a highly poisonous herb/flower with a very romanticized history. The poison comes from an alkaloid called atropine, and the entire plant is poisonous, with the root being the most deadly and the berries being the least. However, just two ingested berries is still enough to kill a child. Some people use Belladonna recreationally as a hallucination, and in Victorian times women often used a tincture of Belladonna to dilate their pupils and make them appear more wide and glassy eyed. Before death, Belladonna can also give you seizures, rapid pulse, and confusion. Don't play with Belladonna, kids.
