Curative effect of warming kidney and fortifying spleen recipe on diarrhea-predominant irritable bowel syndrome

ObjectiveTo observe the curative effect of a recipe for warming the kidney and fortifying the spleen on diarrhea-predominant irritable bowel syndrome (IBS-D).MethodsThis multi-center, double-blind, randomized, and controlled trial included 240 patients that met the inclusion criterion and were then divided into two groups of 120. Patients in the treatment group (group A) took modified Sishen Wan orally for warming the kidney and fortifying the spleen and patients in the control group (group B) took a placebo, Chao Maiya, for 4 weeks. 28 days after withdrawal, there was a 6-month follow-up to observe patient recurrence condition. The total effective rate, curative effect, and recurrence rate were evaluated after treatment.ResultsThere was statistical difference (P<0.01) between the two groups in total effective rate (92.24% in the treatment group and 49.07% in the control group), in curative effect of TCM syndrome (90.52% and 47.22%, respectively), and in the recurrence rate (15.79% and 56.86%, respectively) within 6 months after treatment.ConclusionModified Sishen Wan, for warming the kidney and fortifying the spleen, can effectively treat IBS-D and better control its recurrence.
