A Comprehensive Review of Traditional Chinese Medicine in the Management of Ulcerative Colitis.

Ulcerative colitis (UC) is a chronic, nonspecific inflammatory disorder characterized by symptoms such as abdominal pain, diarrhea, hematochezia, and urgency during defecation. While the primary site of involvement is the colon, UC can extend to encompass the entire rectum and colon. The causes and development mechanisms of UC are still not well understood; nonetheless, it is currently held that factors including environmental influences, genetic predispositions, intestinal mucosal integrity, gut microbiota composition, and immune dysregulation contribute to its development. Dysregulated immune responses are pivotal in the pathophysiology of UC, and these aberrant responses are considered key contributors to the disease onset. In patients with UC, immune cells become hyperactive and erroneously target normal intestinal tissue, resulting in inflammatory cascades and damage to the intestinal mucosa. The therapeutic strategies currently employed for UC include immunosuppressive agents such as aminosalicylates and corticosteroids. However, these treatments often prove costly and carry significant adverse effects - imposing a considerable burden on patients. Traditional Chinese Medicine (TCM) has attracted worldwide attention because of its multi-target approach, minimal side effects, cost-effectiveness, and favorable efficacy profiles. In this review, the ways in which TCM modulates inflammatory responses in the treatment of ulcerative colitis have been outlined. Research into TCM modalities for modulating inflammatory pathways in the treatment of UC, which has yielded promising advancements, including individual herbs, herbal formulations, and their derivatives, has been summarized. TCM has been utilized to treat UC and the immune system plays a key role in regulating intestinal homeostasis. It is imperative to facilitate large-scale evidence-based medical research and promote the clinical application of TCM in the management of UC.
