Belladonna Herb Classic Formulas — Natural Herb Library

Primary Actions

Relieves spasm and alleviates pain - used mainly for gastrointestinal, biliary, and other smooth-muscle cramping patterns where urgent antispasmodic action is needed rather than long-term constitutional treatment.
Restrains excessive secretions - applied for salivation, hypersecretory digestive states, and related nausea-vomiting patterns when anticholinergic drying is therapeutically desired.
Targets ulcer-related and colicky pain - modern Chinese use centers on gastric or duodenal ulcer discomfort, abdominal spasm, and cholecystalgia rather than broad classical pattern treatment.
Functions chiefly through prepared products - Dian Qie Cao is most often prescribed as extract, tincture, or tablet because the raw herb is strongly toxic and requires precise dosing.

Dian Qie Ding (颠茄酊) - belladonna tincture prepared from the herb for smooth-muscle spasm and secretion control, representing a classic manufactured dosage form rather than a decoction formula.
Fu Fang Dian Qie Pian (复方颠茄片) - compound belladonna tablets used in modern Chinese practice for gastrointestinal spasm, ulcer-associated discomfort, and secretion reduction.

TCM Wiki summarizes Dian Qie Cao's core actions as calming spasm to relieve pain and restraining secretion, with indications including nausea, vomiting, cholecystalgia, salivation, and gastric or duodenal ulcer.
Chinese pharmacopoeia-oriented summaries describe the herb as slightly bitter and acrid, warm, and toxic, and emphasize that it is used sparingly in raw-prescription practice because measured alkaloid preparations are safer and more practical.
IMPORT NOTE: This is not a mainstream ancient decoction herb. It is a modern toxic materia medica entry based on Atropa belladonna and should be understood as a standardized spasmolytic drug herb rather than a broadly applied classical tonic or exterior-releasing medicinal.
