This [formula] is [for] wheezing caused by wind-cold constraining the exterior and phlegm-heat smoldering in the interior. This usually occurs in patients with a constitutional tendency toward excessive phlegm who contract wind-cold. When this occurs, the Lung qi is obstructed, its directional flow is disrupted, and the constrained qi transforms into heat. This gives rise to wheezing with thick, yellow sputum that is difficult to expectorate. The greasy, yellow coating on the tongue and the slippery, rapid pulse are also signs of heat and phlegm. Depending on how long this process takes, the patient may still show symptoms of an exterior condition, notably simultaneous fever and chills.* --Bensky: Chinese Herbal Medicine Formulas & Strategies.
