Supplements and enriches qi and yin, supplements the lungs and fortifies the spleen, transforms phlegm, downbears counterflow, clears heat and disinhibits the throat
For chronic, slow-healing dry cough at the tail-end of a respiratory infection due to qi and yin vacuity with lingering heat and phlegm in infants and children. Western medical indications include chronic bronchitis, asthma, pertussis, and pneumonia when presenting the appropriate Chinese medical patterns.
At the end of a respiratory disease or in certain chronic pulmonary diseases, many children’s qi and yin has been damaged by heat evils which may, in fact, still be lingering within the lungs. If there is also still phlegm deep-lying within the lungs, this may result in a chronic dry cough (typically worse in the evenings) which may linger for some time. In this case, it is necessary to supplement the qi and enrich yin at the same time as gently transforming phlegm, clearing heat, and harmonizing the qi. Within this formula, Geng Mi, Da Zao, and Dang Shen fortify the spleen and supplement the qi. Dang Shen and Geng Mi both also have some ability to engender fluids, while Da Zao has some ability to nourish the blood, remembering that blood and fluids share a common source and that qi and blood share a common source. Mai Men Dong enriches yin and moistens dryness, transforms phlegm and clears heat. The fact that Mai Men Dong simultaneously enriches yin and transform phlegm makes it a very special part of the Chinese material medica. Ban Xia transforms phlegm and downbears or harmonizes the qi to help stop coughing. Uncooked Gan Cao helps clear heat, engenders fluids, and disinhibits the throat. In addition, this formula also gently clears stomach heat which is often a co-factor in lung heat due to many children’s tendency to stomach heat. The reason we have chosen this formula for our pediatric line is that it is very gentle and contains relatively few ingredients. This is important when treating children when over-treatment may result in causing various side effects. In fact, it is one of the principles of Chinese medical pediatrics to stop treatment in infants and children when only half cured so as to avoid adverse medicinal reactions.
