Summary of article contents:
Introduction
Terminalia chebula Retz, commonly known as chebulic myrobalan, has a long-standing role in traditional medicine, particularly for treating various ailments, including constipation. The seeds of T. chebula are used for their laxative and diuretic properties, among other therapeutic effects. This study aimed to investigate the pharmacological action of the aqueous extract of T. chebula seeds (ATC) both in vitro and in vivo, with particular focus on its effects on intestinal motility and its potential to alleviate morphine-induced constipation in rats.
Excitatory Effects of ATC on Ileal Contractions
One significant finding from the study was the effect of ATC in enhancing the frequency and tension of ileal contractions in a dose-dependent manner. The in vitro experiments demonstrated that ATC increased the contractile activity of isolated rat ileum segments, with the greatest effects observed at higher concentrations. Notably, the excitatory effects of ATC were not mediated by traditional cholinergic pathways, as the contractions were not inhibited by atropine or hexamethonium, suggesting a different mechanism of action possibly through the activation of calcium channels. Additionally, when calcium was removed from the environment, the ATC-induced contractions were abolished, further implicating the role of Ca2+ in the observed activity.
Conclusion
The results of this study support the traditional uses of Terminalia chebula seeds for managing constipation, highlighting the extract's potential pharmacological effects and its capacity to improve intestinal motility. The ATC not only enhanced the contractile frequency and tension in the ileum but also effectively counteracted the constipative effects of morphine in vivo, making it a promising candidate for further research in gastrointestinal therapies. Overall, these findings underscore the potential of T. chebula as a natural remedy for alleviating constipation, warranting further investigations into its mechanisms and efficacy.
