Commentary states: The *Mai Jing* (Pulse Classic) points out that heat in the Upper Jiao (Upper Burner), due to coughing, develops into Fei Wei (Lung Flaccidity). The etiology of this disease may be due to excessive sweating, vomiting, Xiao Ke (Wasting and Thirsting Syndrome) causing frequent urination, or constipation treated repeatedly with harsh purgatives leading to diarrhea, thereby severely depleting body fluids. Upon examination, the Cun Kou (Radial Pulse at the wrist) pulse is rapid and deficient; the patient experiences chest irritability, excessive salivation, dry lips, difficult urination, a sensation of wanting to cough but being unable to do so, coughing up dry and sticky sputum, and dull pain in the chest.
