Objective To explore the effects of Hewei Tea， a composition of Chinese herbs containing leaves and flowers of Dendrobium officinale， on gastrointestinal function by means of the gastric emptying and small intestine propulsion experiments in vivo， and the tension， amplitude and frequency of isolated intestine. Methods In vivo experiments： Mice were randomly divided into control group， Xiangshaliujun pill group， Hewei Tea drinking group and Hewei Tea lavage group， and treated by a gavage of normal saline（20mL·kg-1）， suspension of Xiangshaliujun pill（2.33g·kg-1）， normal saline（20mL· kg-1）， and decoction of Hewei Tea（0.72 g·kg-1）， once a day， respectively. After 14 days， the mouse were given by gavage with nutritional semisolid paste to measure the rates of gastric emptying and small intestinal propulsion in mice， after deprived of food but not water for 12 hours. In vitro experiments： According to the isolated small intestinal smooth muscle perfusion experiment method， we took the small intestine isolated from SD rats to observed changes of intestinal smooth muscle contraction after adding different doses of Hewei Tea decoction（final concentration in bath was 0.0185、 0.0370、 0.0740、 0.1480g·mL-1） in normal Tyrode’s solution or in the condition of acetylcholine， compared with normal saline and Xiangshaliujiu pill decoction. Results In vivo experiments： Gastric emptying rate of Hewei Tea lavage group significantly reduced（P<0.01）. The pairwise comparison of small intestine propulsion of groups， there was no significant difference（P>0.05）. In vitro experiments： Hewei Tea decoction significantly inhibited intestinal motility of rats with reducing the amplitude， declining tension， slowing down the frequency， and antagonized the contraction of intestinal smooth muscle induced by acetylcholine. Conclusion Hewei Tea decoction has obvious inhibitory effects on gastrointestinal movement， which can relieve intestinal cramps.
