Study on the effect of Jia-Wei-Xiao-Yao-San decoction on patients with functional dyspepsia.

The effect of Jia-Wei-Xiao-Yao-San (JWXYS) decoction on patients with functional dyspepsia was studied by means of electrogastrography (EGG) and symptoms of dyspepsia were assessed. Twenty patients with functional dyspepsia were selected; before and after internal treatment with JWXYS, the integrated symptoms of the patients were down-regulated from 18.55 +/- 3.24 (before treatment) to 11.65 +/- 2.37 (after treatment) (p < 0.01); electrogastrography showed that all the EGG parameters of the patients were outside the normal range. After treatment with JWXYS, all these indices improved before and after dinner. The results showed that the JWXYS decoction could not only improve the symptoms, but also adjust the abnormal gastric motility and gastric myoelectrical activity of patients with functional dyspepsia.
