Inflammatory Bowel Disease (IBD) is a chronic non-specific disease that affects the
gastrointestinal tract, and Intestinal Mucosal Barrier (IMB) damage is closely related to its pathogenesis.
The management of IBD often involves repairing the mechanical, chemical, immune, or
biological barriers of the intestinal mucosa to alleviate symptoms. Currently, the treatment of IBD
patients requires continuous medication or surgical interventions, which can cause irreversible
damage to the patient's body over time. Natural flavonoids, commonly found in human diets, offer
a safe, effective, and non-toxic alternative, presenting significant potential for promoting intestinal
health and disease prevention. This article aimed to explore current research concerning the role of
natural flavonoids in modulating the IMB in IBD, offering a new perspective for the prevention
and management of IBD and highlighting new opportunities for the development and application
of natural flavonoids.
