All five zang organs and six fu organs can cause cough; it is not solely due to the Lung. The skin and hair (Pí Máo) are the exterior correspondence of the Lung. When pathogenic factors first invade the skin and hair, they enter the Lung through this correspondence. If cold food and drink enter the Stomach, they travel up along the Lung meridian to the Lung, causing Lung cold. With Lung cold, external pathogens combine with internal cold fluids, lodging within, resulting in Lung cough. Each of the five zang organs receives disease in its respective season; if not in that season, the disease transmits according to the cycle of generation and restriction. In autumn, when Lung qi prevails, the Lung is affected first; in spring, Liver qi prevails, so the Liver is affected first; in summer, Heart qi prevails, so the Heart is affected first; during the late summer (extreme yin), Spleen qi prevails, so the Spleen is affected first; in winter, Kidney qi prevails, so the Kidney is affected first.

The manifestation of Lung cough includes coughing with wheezing and audible sounds, and in severe cases, expectoration of blood (due to reversal of Lung collaterals). The manifestation of Heart cough includes pain in the heart region upon coughing, a sensation of obstruction in the throat as if something were stuck, and in severe cases, sore throat and throat bi syndrome. The manifestation of Liver cough includes pain under both hypochondria upon coughing, inability to turn the body in severe cases, and fullness under both hypochondria when turning. The manifestation of Spleen cough includes pain in the right hypochondrium upon coughing, dull pain radiating to the shoulder and back, inability to move in severe cases, and aggravated cough upon movement. The manifestation of Kidney cough includes pain radiating between the waist and back upon coughing, and expectoration of saliva in severe cases (the Kidney is the water organ and governs saliva and fluid retention).

If cough from the five zang organs persists for a long time, the pathology transfers to the six fu organs. If Spleen cough does not resolve, it affects the Stomach, becoming Stomach cough. The manifestation of Stomach cough includes coughing and vomiting; in severe cases, roundworms may be expelled (roundworms reside in the intestines and stomach, and severe vomiting causes them to ascend with rebellious qi). If Liver cough does not resolve, it affects the Gallbladder, becoming Gallbladder cough. The manifestation of Gallbladder cough includes coughing and vomiting bile (vomiting bitter fluid). If Lung cough does not resolve, it affects the Large Intestine, becoming Large Intestine cough. The manifestation of Large Intestine cough includes coughing with fecal incontinence (as recorded in *Jia Yi Jing* as "passing stool"). If Heart cough does not resolve, it affects the Small Intestine, becoming Small Intestine cough. The manifestation of Small Intestine cough includes coughing with flatus, where gas expulsion occurs simultaneously with coughing (the Small Intestine connects below to the Large Intestine; qi from the transformation in the Small Intestine moves downward, so coughing causes downward rushing of qi and flatus). If Kidney cough does not resolve, it affects the Bladder, becoming Bladder cough. The manifestation of Bladder cough includes coughing with urinary incontinence. If chronic cough persists, it affects the Sanjiao (Triple Burner), becoming Sanjiao cough. The manifestation of Sanjiao cough includes coughing with abdominal fullness and loss of appetite. The pathology of all these coughs gathers in the Stomach and relates to the Lung, causing excessive phlegm and saliva, facial edema, and rebellious qi (the Yangming meridian originates at the nose, meets at the face, and exits at the mouth, thus causing excessive phlegm/saliva and facial edema; the Lung covers the other organs like a canopy and governs qi, thus causing rebellious qi).

To treat coughs of the zang organs, treat their Shu-stream points (Lung: Taiyuan [LU-9]; Heart: Shenmen [HT-7]; Liver: Taichong [LR-3]; Spleen: Taibai [SP-3]; Kidney: Taixi [KI-3]—note: original text says "Kidney Tai...", likely missing character, or refers to Back-Shu points as an alternative view considered erroneous here). To treat coughs of the fu organs, treat their He-sea points (Stomach: Zusanli [ST-36]; Gallbladder: Yanglingquan [GB-34]; Large Intestine: Quchi [LI-11]; Small Intestine: Xiaohai [SI-8]; Bladder: Weizhong [BL-40]; Sanjiao: Tianjing [SJ-10]). For those with edema, treat their Jing-river points (points where meridians pass, such as Jingqu [LU-8], Yanggu [SI-5], Jiexi [ST-41], Shangqiu [SP-5], etc.). For edema and rebellious qi associated with various coughs, needle according to the affected meridian.
