[0086] Test example

[0087] 1. General information: 144 patients with sore throat caused by upper respiratory tract infection admitted to our hospital from February 2022 to September 2022 were equally divided into Example 1 to 6, Comparative Example 1 and Comparative Example 2, a total of 8 groups. All patients met the dialectical criteria for sore throat caused by upper respiratory tract infection cold wind-heat syndrome, and there were no patients with pregnancy, acute and chronic bronchitis, and major organ dysfunction. The course of disease was 12 to 24 hours. There was no significant difference in the clinical data of the two groups of patients.

[0088] 2. Method: The medications of Example 1 to 6, Comparative Example 1 and Comparative Example 2 were respectively the pharmaceutical compositions obtained according to Example 1 to 6, Comparative Example 1 and Comparative Example 2. The dosage was 0.050 g per time and the medication was administered once a day. The medication was sprinkled on the swollen and painful throat and tonsils. The throat and tonsils would secrete a large amount of secretions. At this time, the medication and secretions could be vomited out together.

[0089] 3. Indicators:

[0090] 1) Relief of sore throat after treatment. Significant relief: Sore throat disappeared or improved significantly; Relieved: The pain level decreased, the redness and swelling area decreased, but the throat felt dry; No relief: The pain was more severe and the voice was hoarse. Relief rate = (significant relief + relief) / total number of cases × 100%. The results are shown in Table 1.

[0091] 2) Clinical effect. Marked effect: symptoms disappeared and did not recur after 48 hours of treatment; effective: symptoms were relieved after 48 hours of treatment; ineffective: did not meet the above criteria. Total effective rate = (marked effect + effective) / total number of cases × 100%. The results are shown in Table 2.

[0092] Table 1. Relief of sore throat in each group of patients after treatment

[0093] Group Number of cases Significant relief ease Not relieved Response rate% Example 1 Group 18 12 5 1 94.4 Example 2 Group 18 11 5 2 88.9 Example 3 Group 18 10 7 1 94.4 Example 4 Group 18 9 7 2 88.9 Example 5 Group 18 12 6 0 100 Example 6 Group 18 14 4 0 100 Comparative Example 1 18 8 5 5 72.2 Comparative Example 2 18 9 5 4 77.8

[0094] As can be seen from Table 1, the remission rates of the groups in Examples 5 and 6 are both 100%, which shows that the pharmaceutical compositions of Examples 5 and 6 have significant therapeutic effects on sore throat. In Example 6, Dragon's Blood was added to the pharmaceutical composition, and the number of cases with significant remission in Example 6 was 14, which was higher than that in Example 5. It can be seen that Dragon's Blood has a promoting effect on improving the treatment of sore throat by the pharmaceutical composition of the present invention. The remission rates of Comparative Examples 1 and 2 are relatively low, and Pueraria lobata was reduced in Comparative Example 1, and Magnolia officinalis was reduced in Comparative Example 2. It can be seen that Pueraria lobata and Magnolia officinalis have a synergistic effect on the treatment of sore throat in the pharmaceutical composition of the present invention.

[0097] As shown in Table 2, the total effective rates of Example 5 and 6 were both 94.4%, which was good. The total effective rates of Comparative Examples 1 and 2 were lower, 61.1% and 55.6%, respectively. It can be seen that the pharmaceutical composition of the present invention has a good therapeutic effect on sore throat. In Comparative Example 1, Pueraria root was reduced, and in Comparative Example 2, Magnolia bark was reduced. It can be seen that Pueraria root and Magnolia bark have a synergistic effect on the treatment of sore throat in the pharmaceutical composition of the present invention.
