Why was Nichinto Effective, Although Rikkunshito and Shohangekabukuryoto were Ineffective? / 日本東洋医学雑誌

A female with persistent emesis after eating was successfully treated with nichinto, although neither various western-style medicines nor Chinese herbal medicines including rikkunshito or shohangekabukuryoto were effective. Considering the constituent crude drugs, we believe riki (moving of qi) medicine is potent against vomiting associated with psychological factors, while hoki (rising of qi) medicine would be extra crude drug in the absence of hikyo (deficiency of digestive function).
