TOE attenuated the severity of clinical symptoms and inflammatory infiltration in DSS‐induced colitis. A, Representative schematic of the mice in control, DSS, TOEL and TOEH groups. B, Comparison of the mean bodyweight in these four groups (*P < .05, DSS vs TOEH; **P < .01, DSS vs TOEL). C, Comparison of the alterations in disease activity index (DAI; ***P < .001, DSS vs TOEH or TOEL). D. Representative schematic of the colon samples in control, DSS, TOEL and TOEH groups. E. Comparison of the mean colon lengths (***P < .001, control vs DSS; *P < .05, DSS vs TOEH). F, H&E analysis of the histopathological scoring in colon tissue samples from these four groups (4×, 10×, 20×, 40×). G, Comparison of the histopathological scores in colon tissue samples from these four groups. (***P < .001, control vs DSS; *P < .05, DSS vs TOEH)
