Background Chronic constipation is a gastrointestinal functional disorder which affects patient quality of life. Therefore, many studies were oriented to search herbal laxative agents. In this study, we investigated the effect of Globularia alypum L. leaves aqueous extract (GAAE) against loperamide (LOP)‐produced constipation. Methods Animals were given LOP (3 mg/kg, b.w ., i.p. ) and GAAE (100, 200, and 400 mg/kg, b.w ., p.o .) or yohimbine (2 mg/kg, b.w., i.p. ), simultaneously, for 1 week. Gastric‐emptying test and intestinal transit were determined. Colon histology was examined, and oxidative status was evaluated using biochemical‐colorimetric methods. Key Results GAAE ameliorates significantly gastric emptying (64% to 76.5%) and intestinal transit (66.65% to 84.73%). LOP negatively influenced defecation parameters and generated a stress situation. GAAE administration in contrast ameliorated those parameters and re‐established oxidative balance. Conclusion GAAE showed a modest action against oxidative stress and decreased LOP effect and thereby can be considered a pharmacological agent in constipation.
