This study aimed to determine whether the ethanolic extract of <i>A. distichum</i> leaves (ADE) could alleviate dextran sulfate sodium (DSS)-induced colitis in mice. The mice were divided into three groups, and the experimental group was given 300 mg/kg ADE for 4 weeks.

The clinical symptoms of colitis and damage to colon tissue, including the increase in <i>Enterobacteriaceae</i> abundance and a decrease in <i>Bifidobacterium</i> in the colon, were evaluated during DSS treatment. DSS overactivated the nuclear factor (NF)-κB signaling pathway, resulting in excessive production of pro-inflammatory cytokines. In contrast, ADE alleviated the DSS-induced colitis symptoms, protected against colonic tissue damage, and restored the balance of <i>Enterobacteriaceae</i> and <i>Bifidobacterium</i> levels in the colon. Moreover, ADE effectively inhibited the DSS-induced overactivation of the NF-κB signaling pathway within the colon and mitigated abnormal inflammatory responses.
