Traditional Chinese medicine believes that the production of phlegm is mainly related to the lungs and spleen. The lungs govern breathing and regulate the entry, exit, rise and fall of Zong Qi (vital energy). If the lungs are deficient, coughing, wheezing, and uneven lying posture may occur. When wind evil or cold evil invades the lungs, the body fluid in the lungs condenses into phlegm. The spleen governs transportation and transformation, that is, digesting and transporting nutrients to various organs. If dampness invades the human body, or overthinking, fatigue, and improper diet can damage the spleen and cause it to lose its function of transportation and transformation, causing water and dampness to stop condensing and form phlegm. , Chinese patent medicines for resolving phlegm:
