Potential of phytomedicine in the treatment of inflammatory bowel disease

Inflammatory bowel disease (IBD) is a chronic inflammatory intestinal disease caused by an abnormal response of the intestinal mucosal immune system, including ulcerative colitis and Crohn's disease. IBD is also accompanied by extraintestinal complications, such as joint, skin, and eye diseases. In recent years, phytomedicine has played an important role in the treatment of IBD because of its strong anti-inflammatory activities and minor side effects. Due to the lack of a review of the literature examining the extent to which phytomedicine can be used to treat IBD, this paper summarizes the experimental research on IBD from the perspective of phytomedicine according to the structural classification of phytomedicine and provides a reference for the further development of new IBD therapies.
