(From *Suwen: Ping Re Bing Lun*)

The Yellow Emperor asked: There is a disease characterized by fever, sweating, and vexation with fullness. The vexation and fullness do not resolve after sweating. What kind of disease is this? (The phrase "does not resolve after sweating" means that the heat and vexation remain unchanged after perspiration.) Qibo replied: Sweating accompanied by fever indicates Wind pathogen; sweating accompanied by unresolved vexation and fullness indicates Jue (reversal) pathology. This disease is named Feng Jue (Wind Jue). The Yellow Emperor said: I wish to hear the details. Qibo said: The Foot-Taiyang Bladder Meridian governs the exterior Qi, so it is the first to be invaded by pathogens. The Foot-Shaoin Kidney Meridian forms an interior-exterior relationship with it. When heat is received, the Shaoyin Qi follows the Yang upward; following upward leads to Jue. (Wind is a Yang pathogen, so although sweat is produced, the body remains hot. The Foot-Taiyang Meridian governs the exterior Qi. Exterior illness elicits an interior response; thus, when Shaoyin receives heat, the Yin Qi also follows the Yang and rebels upward. Rebellion constitutes Jue, hence the name Feng Jue. Note: The meaning of Feng Jue varies. As described in this chapter, it refers to concurrent Taiyang and Shaoyin diseases. In *Yinyang Bie Lun*, it states that onset involving Er Yang (Stomach) and Yi Yin (Liver) is named Feng Jue, referring to the Stomach and Liver. See Section 6 of this category for details. In *Wu Bian Pian*, it says those prone to Feng Jue with profuse sweating have insecure flesh and loose cou li [pores]. See Section 76 of this category for details. All these should be cross-referenced to clarify their meanings.) The Yellow Emperor asked: How should it be treated? Qibo said: Acupuncture both the exterior and interior meridians, and administer decoctions. (When Yang pathogens are excessive, Yin must be deficient. Therefore, one should drain the heat of the Foot-Taiyang Meridian and tonify the Qi of the Foot-Shaoyin Meridian, needling both exterior and interior meridians together. Administering decoctions aligns with the principle in *Maidu Pian* that deficiency conditions are treated with medicinal drinks to tonify.)

The Yellow Emperor asked: What is the nature of Lao Feng (Labor-induced Wind) disease? Qibo said: Lao Feng typically manifests below the Lungs. (Lao Feng results from wind invasion due to overexertion. "Below the lungs" refers internally to the region between the chest and diaphragm, and externally to the area between the fourth and fifth thoracic vertebrae. Wind invading from the exterior affects the interior. Anyone suffering from overexertion will experience asthma/dyspnea, indicating that labor injures the Lungs. Note: Wang Bing stated that "Lao" refers to Kidney exhaustion. The Kidney meridian ascends from the Kidneys, passes through the Liver and diaphragm, and enters the Lungs; thus, wind generated by Kidney exhaustion rises to reside below the Lungs. This is one interpretation, but since "labor" as a cause involves many aspects, it likely extends beyond just the Kidney meridian.) The symptoms include stiffness and rigidity of the neck and upper back, and blurred vision. (Pathogens located below the Lungs cause rebellious Qi and asthma, leading to neck stiffness preventing bowing of the head. Wind-heat obstructing upwards causes aversion to wind and photophobia, leading to squinting or closed-eye vision.) The patient expectorates sputum resembling mucus, experiences aversion to wind, and chills. This constitutes Lao Feng disease. (Wind-heat damages Yin, causing body fluids to become thick and turbid, resulting in expectoration resembling mucus. The Lungs govern the skin and hair; injury to Wei Qi [Defensive Qi] causes aversion to wind and chills.) The Yellow Emperor asked: How should it be treated? Qibo said: First rescue the condition of neck stiffness and rigidity. (The severity of the wind is manifested in the neck stiffness; therefore, this symptom must be addressed first. However, treating this requires warming the Lungs first. Warming the Lungs disperses the wind; once the wind is dispersed, the neck stiffness resolves. If warming and dispersing methods fail, stagnation may transform into heat, after which clearing and resolving methods can be used. Improper use of warming versus clearing methods will worsen the disease. "Fu" [bending forward] is synonymous with "Fu".) If the Foot-Taiyang Jing's essence is robust, recovery occurs in three days; if middle-aged, in five days; if essence is depleted, in seven days. (Wind pathogens attacking the Lungs enter the Zang organs via acupoints such as Fengmen and Feishu on the Foot-Taiyang Bladder Meridian. The Taiyang is the residence of water and the exterior of the Three Yang meridians. Thus, guiding essence upward allows wind to be coughed out. If Taiyang Qi is strong and guides essence rapidly, recovery should occur within three days. Middle-aged individuals with declining essence should recover within five days. Elderly individuals with depleted essence should recover within seven days. Recovery is marked by the expectoration of green-yellow phlegm and nasal discharge, as described below, which constitutes the guiding of essence.) The patient expects green-yellow phlegm resembling pus, sized like a pill, expelled from the mouth or nose. If not expelled, it injures the Lungs; injuring the Lungs leads to death. (Inability to cough up phlegm corresponds to modern dry cough. It may lead to depletion of Metal and Water [Lung and Kidney], presenting as consumptive disease, hence fatal. Wang Bing stated: Chronic cough exits from the throat to the mouth. Sudden acute cough results from Qi rushing against the Xumen [accumulation gate] and exiting through the nose. Such cases result from exhausted Kidney Qi, empty Lung Qi, and surging Yang Qi. Thus, failure to expel phlegm injures the Lungs and causes death. Note: Wang Bing's term "Xumen" originates from *Yingqi Pian*; see Category 24 on Meridians for details.)
