Yellow Emperor asked: What is the nature of the disease known as Labor Wind (Laofeng)? Qibo replied: The location of Labor Wind is typically below the Lung. This disease causes stiffness in the neck and upper back, blurred vision, expectoration of thick sputum resembling mucus, aversion to wind, and chills. This constitutes the disease of Labor Wind.

Yellow Emperor asked: How should it be treated? Qibo replied: The treatment aims to relieve difficulty in bending and extending the body. For individuals with abundant essence and qi in the Taiyang Meridian (Greater Yang Meridian), recovery occurs in three days; for middle-aged individuals, five days; and for those with deficient essence and qi, seven days. During this process, they will cough up greenish-yellow nasal discharge or sputum, which resembles thick pus and is as large as a bullet. It is expelled from the mouth or nose. If not expelled, it damages the Lung, and damage to the Lung leads to death.

(Commentary) The Taiyang Meridian lies superficially in the skin and hair, and the skin and hair are the exterior correspondence of the Lung. Chronic labor injures Lung Qi, allowing Wind pathogen of the Taiyang to enter the Lung via deficiency. Lung Qi governs descent, so the pathogen moves downward to below the Lung. The Taiyang Meridian serves as the upper margin of the eyelids; when Wind pathogen attacks this meridian, the eyes cannot look straight ahead, forcing an upward gaze, resulting in dim or unclear vision. The pathogen below the Lung binds with body fluids, causing the expectoration of thick sputum like mucus. Since the exterior pathogen remains, there is aversion to wind and chills. Because this arises from injury due to labor followed by Wind invasion, it is named Labor Wind. The Taiyang Meridian runs along the back, causing back stiffness and inability to bend or extend. Treatment should first address the difficulty in movement. If using acupuncture to guide the essence and qi of the Taiyang Meridian, it takes three days for those with robust essence; for middle-aged or declining individuals, five to seven days are needed. Once essence and qi regenerate, the internalized pathogen gradually exits, manifested as coughing up greenish-yellow sputum resembling pus, large as a bullet, expelled from the mouth or nose, leading to recovery. If the pathogen does not exit, it damages the Lung, potentially leading to loss of voice or Lung Abscess (Feiyong), resulting in death. Guiding Taiyang essence and qi pharmacologically involves uplifting Lung Qi and unblocking the Taiyang Meridian.

In *Suwen*, Chapter "Disease Capabilities": Yellow Emperor asked: There is a patient with fever, limb flaccidity and weakness, profuse sweating as if bathing, aversion to wind, and shortness of breath. What disease is this? Qibo replied: This disease is named Wine Wind (Jiufeng). Treat it with Zexie (Rhizoma Alismatis) and Baizhu (Radix Atractylodis Macrocephalae), each ten parts, and Muxian (Herba Siegesbeckiae), five parts. Mix them, take three tuas per dose, and administer after meals.

(Commentary) Heat from wine injures the surface, causing Wind pathogen to invade while pores are open. Internal dampness prevails, leading to profuse sweating, aversion to wind, shortness of breath, fever, and physical lassitude. Hence, it is named Wine Wind. This corresponds to the "Leakage Wind" (Loufeng) mentioned in the previous chapter "Wind Diseases," referring to contracting Wind after drinking alcohol. Treatment uses Zexie and Baizhu to strengthen the Spleen and remove dampness, and Muxian grass to dispel Wind pathogen. Mixed into a powder, three tuas are taken, followed by rice to aid absorption.
