Body weight, disease activity index (DAI) score, and colon length were recorded, and histopathological changes of colon tissues were observed using hematoxylin and eosin (HE) staining. The expression of pro\u2010inflammatory and anti\u2010inflammatory factors in colitic mice and IEC\u20106 cells was detected by ELISA and qRT\u2010PCR. Moreover, we also detected the effect of HDG on the levels of GSH, SOD, and CAT in DSS\u2010treated mice. Subsequently, the influences of HDG on intestinal barrier impairment were explored by using western blot and immunofluorescence. Next, network pharmacology analysis, RNA sequencing analysis, western blot, immunofluorescence, and rescue experiments were utilized to explore the latent mechanisms of HDG on ulcerative colitis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>HDG alleviated DSS\u2010induced ulcerative colitis in mice via ameliorating intestinal barrier impairment, inflammation, and oxidative stress. HDG also improved epithelial barrier function and inflammatory responses in LPS\u2010stimulated IEC\u20106 cells. Besides, we discovered that HDG could inhibit the activation of EGFR\/p38 MAPK signaling. Subsequently, rescue experiments using NSC228155 or anisomycin revealed that HDG could improve epithelial barrier function and inflammation via suppressing the activation of the EGFR\/p38 MAPK pathway in LPS\u2010induced IEC\u20106 cells.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Our
