[Research progress of Baizhu Shaoyao powder in treating ulcerative colitis]

Ulcerative colitis is a chronic, nonspecific and complex intestinal disease. The current clinical treatment guideline of this disease recommends a variety of options with oral western medicines, such as aminosalicylic acids, glucocorticosteroids, and immunosuppressors. However, due to their unstable therapeutic effects, high toxicities, and strong drug dependence, they are not suitable for long-term administration. Baizhu Shaoyao powder, a traditional Chinese medicinal prescription, is clinically and commonly used for tonifying spleen and softening liver as well as eliminating dampness and relieving diarrhea. Recent researches suggest that Baizhu Shaoyao powder has significant effect in the treatment of ulcerative colitis. This article reviewed the research progress on the curative effect and action mechanism of Baizhu Shaoyao powder in treating ulcerative colitis, and provided the ideas and directions for its further research in future.
