Belladonna (Atropa belladonna), also called deadly nightshade, is a highly poisonous member of the nightshade family. Its attractive berries and long medicinal history can make it especially hazardous when misidentified or handled casually.
Poison Warning
Belladonna is poisonous. Do not prepare it as tea, tincture, food, or home medicine. All parts contain tropane alkaloids, including atropine and scopolamine, with particularly serious risk from berries and roots.
Identification
The perennial bears dull purple-brown bell-shaped flowers and glossy black berries surrounded by a green calyx. Correct identification is critical because ingestion can be life-threatening.
Historical Medicinal Use
Belladonna compounds became important in medicine because carefully measured purified alkaloids can affect the parasympathetic nervous system. Historical herbal use, however, carried a narrow margin between pharmacologic effect and poisoning.
Poisoning Signs
Toxic exposure can cause dry mouth, dilated pupils, blurred vision, rapid heartbeat, urinary retention, agitation, confusion, hallucinations, overheating, seizures, coma, and death. Suspected ingestion requires urgent poison-control or emergency medical evaluation.
Research & Modern Medicine
Modern medicine uses standardized atropine and related drugs for specific indications under controlled dosing. That does not make crude belladonna plant material safe for self-treatment.
Safety
Home dosing is unsafe. Keep the plant away from children and animals. Gloves are sensible when handling plant material, and hands should be washed afterward.
Folklore
Belladonna has centuries of association with poison lore, witchcraft, cosmetics, vision, trance, and European magical tradition.
