Answer a few quick questions to see if you may meet the eligibility requirements.
Trial Objectives and Exploration Indicators：
1. To explore the improvement effect of different doses of Qinqiao Yanshu Granules on the symptoms/conditions and TCM syndromes of acute pharyngitis (Wind - Heat Exogenous Syndrome), and its effect on shortening the course of the disease.

Trial Objectives and Exploration Indicators：
1. To explore the improvement effect of different doses of Qinqiao Yanshu Granules on the symptoms/conditions and TCM syndromes of acute pharyngitis (Wind - Heat Exogenous Syndrome), and its effect on shortening the course of the disease.
2. To observe the safety of the clinical application of Qinqiao Yanshu Granules. Overall Trial Design：A block - randomized, double - blind, dose - escalation, multicenter clinical trial design was adopted.
Sample Size：It is planned to enroll 72 cases in each group (high - dose group, low - dose group, and extremely low - dose group), with a total of 216 cases.
Investigational Products：Experimental groups:
1. High - dose group: Specification: 12g/bag;
2. Low - dose group: Specification: 12g/bag.
Control group:
(1) Extremely low - dose group: Specification: 12g/bag.
Rescue medication:
(1) Paracetamol tablets: Specification: 0.5g/tablet. Dosage and Administration： High - dose group: Dissolve in boiling water and take 1 bag each time, 3 times a day, half an hour before meals; Low - dose group: Dissolve in boiling water and take 1 bag each time, 3 times a day, half an hour before meals; Extremely low - dose group: Dissolve in boiling water and take 1 bag each time, 3 times a day, half an hour before meals; Rescue medication: Paracetamol tablets. During the trial, if the subject's body temperature exceeds 38.5°C (including 38.5°C), rescue medication can be added. Use it according to the instructions and doctor's advice and record it truthfully.
Treatment Course：5 days Efficacy Indicators：
1\) The disappearance rate of pharyngeal pain 3 days and 5 days after treatment; 2) The change value of the pharyngeal pain VAS score compared with the baseline 5 days after treatment; 3) The time to disappearance of pharyngeal pain; 4) The effective rate of pharyngeal signs 5 days after treatment; 5) The clinical cure rate of the disease 5 days after treatment; 6) The efficacy of TCM syndromes 5 days after treatment; 7) The disappearance rate of single symptoms 5 days after treatment; 8) The frequency of rescue drug use. Measurement and Definition of Endpoint Indicators：
1. The criterion for the disappearance of pharyngeal pain: The pharyngeal pain VAS score drops to 0 points and persists for 24 hours or more.
2. Pharyngeal pain VAS score:
Starting from the evaluation time of the VAS score during the screening period, the subject evaluates once every 24 hours (±1 hour) and records the most severe degree of pharyngeal pain in the past 24 hours in the diary card.
3. The criterion for the effective rate of pharyngeal signs: "Effective" is defined as a decrease of at least 1 point in the pharyngeal sign score. The effective rate = (Number of effective cases / Total number of cases) × 100%.
4. The criterion for the clinical cure of the disease: The clinical symptoms of the disease disappear, and the pharyngeal signs are reduced to mild or less. The cure rate = (Number of cured cases / Total number of cases) × 100%.
5. The definition of the efficacy of TCM syndromes:
Efficacy of TCM syndromes: Cure means that the TCM syndrome score decreases by ≥ 95%; Marked effect means that the TCM syndrome score decreases by ≥ 70% and \< 95%; Effective means that the TCM syndrome score decreases by ≥ 30% and \< 70%; Ineffective means that it does not meet the above criteria.
The change value of the pharyngeal pain VAS score compared with the baseline = The baseline pharyngeal pain VAS score - The pharyngeal pain VAS score on the 6th day.
