Elucidation:
The syndrome results from impairment of yin by warm-heat and summer-heat, or impairment of qi and yin due to impairment of the lung by protracted cough. It should be treated by means of invigorating qi and nourishing yin, and concurrently arresting perspiration and relieving cough. The first ingredient acts as monarch drug to replenish qi and promote the production of body fluid for invigorating the lung. Ingredient No. 2 is used as minister drug to nourish yin and clear away heat for moistening the lung.

The last ingredient can not only astringe yin and arrest perspiration, but also astringe the lung and relieve cough, acting as adjuvant drug. Respectively with tonic, moist and astringent effect, the three ingredients are together used to achieve the results of invigorating qi and nourishing yin, preserving yin to arrest perspiration, moistening the lung to stop cough, and promoting the production of body fluid to quench thirst.
