Patients in the observation group were given 400 ml of Yu Ping Feng San in the mornings and evenings except from the same treatment as the control group. The clinical efficacy， disappearance time of clinical symptoms， symptom score and adverse effects of the two groups were compared after 2 courses of treatment. Results： The total effective rate of the observation group after one treatment course and two treatment courses were 83.33% and 95% respectively， which were both significantly higher than those of the control group. The disappearance time of nasal congestion， nasal itching， sneezing and runny nose symptoms in the observation group were (6.12 ± 2.43) d， (7.65 ± 2.59) d， (3.27 ± 1.86) d and (3.11 ± 1.42) d respectively， which were all significantly shorter than those of the control group (P<0.05). The overall symptom score in the observation group was (2.57 ± 1.04) points， significantly lower than that of the control group (3.86 ± 1.20) points (P<0.05).The total adverse reaction rate and recurrence rate was only 6.67% and 11.67% in the observation group， significantly lower than that of the control group (P<0.05).
