However, the underlying mechanisms of its action remain unclear. This study aimed to assess the laxative effects of ZYG on diphenoxylate-induced constipation in Kunming mice and clarify the underlying mechanism of action of ZYG in treating constipation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A model of constipation induced by diphenoxylate was developed. The laxative effect was evaluated based on the discharge time of the first black stool, fecal number, fecal weight, intestinal propulsion rate, and intestinal moisture content. Enzyme-linked immunosorbent assay was used to analyze the expression of inflammatory cytokines and neurotransmitters in serum. Histopathological analysis of colon tissues was performed using hematoxylin\u2013eosin staining. Real-time quantitative polymerase chain reaction, immunohistochemistry, and western blotting were used to analyze the mRNA and protein expression of the stem cell factor (SCF)\/c-Kit tyrosine kinase (c-Kit) signaling pathway. The composition of the mouse intestinal microbiota was determined by 16S rDNA sequencing.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>ZYG improved intestinal peristalsis, defecation frequency, and intestinal moisture content. ZYG decreased the abundance of <jats:italic>Firmicutes<\/jats:italic> at the phylum and genus levels and increased the abundance of <jats:italic>Bacteroidetes<\/jats:italic> at the genus level.
