Hematoxylin and eosin (H&E) staining was used to visualize the intestinal tissues, and measurements were taken for villus height, crypt depth, and the villus-to-crypt ratio. Control represents the blank control group, Positive represents the positive control group, High represents the high-concentration treatment group, Medium represents the medium-concentration treatment group, and Low represents the low-concentration treatment group.
