Atropa belladonna, commonly known as belladonna or deadly nightshade, is a perennial herbaceous plant (rhizomatous hemicryptophyte) in the Nightshade family (which includes tomatoes, potatoes, eggplant, etc.) Solanaceae, native to Europe, North Africa, and Western Asia.
Belladonna also reduces the secretions of many organs, thereby helping to control conditions such as excessive stomach acid production. Belladonna is used to treat the rigidity, tremor, excessive salivation, and sweating caused by Parkinson's disease.
