Diarrheal diseases are a major cause of morbidity and mortality throughout the world and particularly in developing countries. <jats:italic>Nauclea diderrichii<\/jats:italic> is a plant used in traditional medicine in the treatment of anemia, fever, gastric ulcer, malaria, abdominal pain, skin infections, and diarrhea. The present work is aimed at evaluating the antisecretory and spasmolytic activities of aqueous and ethanolic stem bark extracts of <jats:italic>Nauclea diderrichii<\/jats:italic> in Wistar rats. <jats:italic>Methods<\/jats:italic>. The effect of aqueous and ethanolic extracts of <jats:italic>Nauclea diderrichii<\/jats:italic> was tested at doses of 100, 200, and 300\u2009mg\/kg on castor oil\u2010induced secretory diarrhea, misoprostol\u2010induced fluid accumulation, and the effect of pretreatment with yohimbine and glibenclamide. They were also tested on normal motility and castor oil\u2010 and carbachol\u2010induced hypermotility. <jats:italic>Results<\/jats:italic>. The results showed that the aqueous and ethanolic extracts of <jats:italic>Nauclea diderrichii<\/jats:italic> significantly (<jats:italic>p<\/jats:italic> &lt; 0.001) inhibited castor oil\u2010induced secretory diarrhea at all the doses. Both extracts significantly (<jats:italic>p<\/jats:italic> &lt; 0.001) inhibit fluid accumulation induced by misoprostol. The pretreatment with glibenclamide reduced the antidiarrheal activity of aqueous extract of <jats:italic>Nauclea diderrichii<\/jats:italic>. The pretreatment with yohimbine did not alter the effect of the aqueous extract of <jats:italic>Nauclea diderrichii<\/jats:italic>. On intestine transit as on castor oil\u2010 and carbachol\u2010induced motility, the aqueous and ethanolic extracts at doses of 100 and 200\u2009mg\/kg reduced significantly (<jats:italic>p<\/jats:italic> &lt; 0.05, <jats:italic>p<\/jats:italic> &lt; 0.01, and\u2009<jats:italic>p<\/jats:italic> &lt; 0.001) the travelled distance by charcoal and peristaltic index. <jats:italic>Conclusions<\/jats:italic>. The study demonstrated that the aqueous and ethanolic extracts of <jats:italic>Nauclea diderrichii<\/jats:italic> possess antisecretory and antispasmolytic properties hence its use in traditional medicine against diarrhea.<\/jats:p>","DOI":"10.1155\/2022\/7569848","type":"journal-article","created":{"date-parts":[[2022,6,20]],"date-time":"2022-06-20T04:35:08Z","timestamp":1655699708000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Antisecretory and Spasmolytic Activities of Aqueous and Ethanolic Stem Bark Extracts of <i>Nauclea diderrichii<\/i> in Wistar Rats"],"prefix":"10.1155","volume":"2022","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4675-9656","authenticated-orcid":false,"given":"R.
