Chinese medicine believes that the formation of phlegm-dampness is closely related to the dysfunction of three internal organs, including the lungs, spleen and kidneys. Among them, the dysfunction of the spleen is the most obvious, because the spleen is responsible for transporting water and dampness, while the lung is the organ for storing phlegm, so phlegm-dampness manifests itself as a dysfunction of the spleen’s transport, and the patient appears to be poorly nourished, nauseated, vomiting, and physically heavy. If phlegm-dampness blocks the lung, the patient may have cough, sputum, sputum is more sticky and not easy to cough. In addition, patients with phlegm-dampness containing the lung as well as phlegm-dampness for a long time will affect the kidney transpiration and qi, which can be manifested as patients with clinical symptoms of soreness and weakness of the waist and knees, and clear and long urine. Therefore, the formation of phlegm-dampness needs to be combined with the patient’s comprehensive clinical manifestations to locate the lesions in the lung, spleen and kidney. At the same time, the treatment needs to take into account the lung, spleen, and kidney in an integrated manner.
