A Clinical Study on the Prevention of Mild to Moderate Intermittent Asthma With Chinese Medicine Weiyang Yuping Fang

Study Overview
=================
Brief Summary
-----------------
Clinical exploring study of Weiyang Yuping Decoction in preventing acute attacks of mild to moderate intermittent asthma Based on the theory of Preventing disease from exacerbating in Chinese medicine.

Detailed Description
-----------------
Based on the preliminary clinical and basic research, this project intends to highly optimize and integrate the TCM treatment of disease theory with the current methods to form two preventive treatment plans, one treatment group was given Weiyang Yupingfang Granules orally for 1 month on the Sanfudays and on the Sanjiu days each year for a total of 2 months one year; the other treatment group was given Weiyang Yupingfang Granules orally for 1 month in the first month of each quarter in the four quarters of the year, for a total of 4 months one year.; Comparing the effect of prevention and treatment of mild to moderate intermittent asthma exacerbations of the two prevention methods , provides new ideas for the prevention and treatment of bronchial asthma in the future, and further improves bronchial The level of prevention and treatment of asthma.
