Belladonna, also known as deadly nightshade, is a perennial herbaceous plant native to Europe, North Africa, and Western Asia. It contains toxic compounds, primarily atropine, scopolamine, and hyoscyamine, which can cause severe poisoning if ingested. The plant features bell-shaped purple flowers and shiny black berries, which are particularly attractive but highly dangerous. Historically, belladonna has been used in medicine for its anticholinergic properties, helping to treat various conditions like muscle spasms and motion sickness. However, due to its toxicity, it is crucial to handle this plant with care and avoid consumption without professional guidance.
