Deadly nightshade plant, also known as Atropa belladonna, is a perennial plant of the Solanaceae family. The plant has extremely poisonous foliage and berries. Belladonna contains scopolamine and hyoscyamine toxins, which can cause hallucination and delirium.
The deceptive color of the berries poses the greatest danger to children, since ingesting two berries can lead to death. The symptoms of belladonna poisoning include blurred vision, thirst, vomiting, hallucinations and slurred speech. Herbal medical practitioners cultivate deadly nightshade in North America, France and England for use as herbal medicine. One pharmaceutical use for deadly nightshade is the treatment of eye diseases. Practitioners also use it as an anti-inflammatory and pain-relief agent.
