Abstract: Aim To explore the efficacy and safety of Chunyang zhengqi (Chu) capsule in treatment of acute gastro- enteritis. Methods Fifty patients with acute gastro- enteritis (cold and damp syndrome) were randomly divided into a therapeutic group of 30 cases and acontrol group of 20 cases. In the therapeutic group each patient received 2 capsules of Chu capsule, twice daily, while in the control group received 3 grams of Chu pill, twice daily. Results After 3 days of treatment, 8 cases were cured, 15 improved obviously, 4 improved, and 3 improved insignificantly in the therapeutic group. There was no significant difference between the two groups in the total effective rate (90.0 % vs 85.5 %, μ=0.180, P >0.05). Conclusions Chu capsule and pill have similar therapeutic efficacy and safety in treatment of acute gastro-enteritis.
