[ANALYSIS OF FORMULA]: It is a main formula for treatment of damp phlegm. Pinellia tuber in the formula being pungent in flavor and warm and dry in properties is used as a principal herb to strengthen the spleen and dry dampness, lower the adverse flow of qi, resolve phlegm and harmonize the stomach to stop vomiting. Tangerine peel as an assistant herb, with effects of regulating qi and dr­ying dampness, enables the qi to flow normally and gets the phlegm cleared. Act­ing as an adjuvant herb, poria strengthens the spleen and excretes dampness. When dampness is cleared, the spleen becomes healthy. Fresh ginger, being able to lower the adverse qi and resolve phlegm, not only reduce the toxic action of pinel­lia tuber, but also assist pinellia tuber and tangerine peel in activating qi and remo­ving phlegm, A little black plum is used to astringe the lung-qi, and the combina­tion use of pinellia tuber and black plum produces the double effects of both dis­persion and astringing. They are opposite and complementary each other, so that to remove phlegm without impairment of the genuine-qi. Roasted licorice root, as a dispatcher herb, coordinates the effects of the other herbs, moistens the lung and regulates the middle. The combination of the six herbs results in drying damp­ness, resolving phlegm, regulating qi and harmonizing the middle. It is better to use vintage pinellia tuber and vintage tangerine peel in the formula, thus named “Two vintage herbs”.

Today, it is usually used for chronic bronchitis, gastritis, Meniere’s syn­drome, neurogenic vomiting and other diseases manifested as damp-phlegm syn­drome in clinical practice.
