In ICR mice with loperamide-induced constipation, Elsholtzia ciliata aqueous extract (ECAE) and Hovenia dulcis aqueous extract (HDAE) significantly ameliorated constipation symptoms, mitigated colonic pathological tissue damage, significantly increased the expression levels of proteins associated with the promotion of intestinal peristalsis [Stem Cell Factor Receptor (c-Kit) and Stem Cell Factor (SCF)] and the maintenance of the intestinal barrier [Zonula Occludens-1 (ZO-l), Occludin and Claudin-l], and promoted beneficial intestinal bacterial colonization. The gene discussed is KITLG; the disease is Constipation.
