Objective To study the effects of compound Chinese medicine containing Codonopsis pilosula produced in Yunnan province（known as Choushen） on promoting digestion and purgation. Methods Mice were randomly divided into control group， model group and different dosage groups（0.41g·kg-1， 0.82g·kg-1， 1.64g·kg-1， 3.28g·kg-1）. The time of the first stool， grain numbers of stool， stool weight in mice， the propulsion rate of intestine， after administration were observed. Results In the mice defecation test， the time of the first stool（227.75±38.82min） at the dosage of 3.28g·kg-1 was much shorter compared with the model group（269.38±44.41min）（P<0.05）. The stool weight（0.537±0.203g） of 3.28g·kg-1 group was heavier versus the model group（0.242±0.178g）（P<0.01）. In addition， the grain numbers of stool （22.63±6.14） of highest group also significantly increased when compared with model group（13.75±8.24）（P<0.01）. In the mice digestion test，the intestinal propulsive rate of the treatment group was significantly higher than that of the model group（P<0.05）， the intestinal propulsive rate of 5-day administration was higher than that of 1 day or 3 days. Conclusion The present compound Chinese medicine containing C.pilosula possesses significant effects on purgation promotion and this effect might be associated with digestion promotion， suggesting its potential roles in the development of healthcare foods.
