In\u00a0vitro, norepinephrine (NE) was used to stimulate isolated ileal smooth muscle of rats to imitate the state of insufficient gastrointestinal motility during STC, and a model of excessive relaxation of isolated ileal smooth muscle was established. This model was used to observe and record the changes in contraction tension, amplitude, and frequency of ileal smooth muscle after treatment with WCA, EE, AE, and the active ingredients of WCA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Key Results<\/jats:title>\n                    <jats:p>In vivo, WCA, EE, and AE treatment increased fecal parameters, improved gastrointestinal transit time, and alleviated pathological damage to the colon in STC rats.
