帝曰∶何以异之？岐伯曰∶肺咳之状，咳而喘息有音，甚则唾血；心咳之状，咳则心痛，喉仲介介如梗
状，甚则咽肿喉痹；肝咳之状，咳则两胁下痛，甚则不可以转，转则两 下满；脾咳之状，咳则右 下痛，阴
阴引肩背，甚则不可以动，动则咳剧；肾咳之状，咳则腰背相引而痛，甚则咳涎。
五脏部位不同，经脉流行各别，故其受邪而致咳者，各有病状不同，辨其状，方知病邪之所在而治之。受
邪之脏为本，肺为标，拔其本，则标自愈而咳可止。今人但知治肺，无怪其不效也。
五脏之久咳，乃移于六腑。脾咳不已，则胃受之，胃咳之状，咳而呕，呕甚则长虫出；肝咳不已，则胆受
之，胆咳之状，咳呕胆汁；肺咳不已，则大肠受之，大肠咳状，咳而遗矢；心咳不已，则小肠受之，小肠咳
状，咳而失气，气与咳俱失；肾咳不已，则膀胱受之，膀胱咳状，咳而遗溺；久咳不已，则三焦受之，三焦咳
状，咳而腹满，不欲食饮。此皆聚于胃，关于肺，使人多涕唾，而面浮肿气逆也。
脏病久不已则移于腑，其咳也亦各有证状可辨。长虫，即蛔虫也。胆汁，苦水也。三焦包脏腑之外，故末
传三焦。而胃又为脏腑之海，肺主一身之气，故其病虽发于各脏腑，而必皆聚于胃，关于肺，乃成咳病，如不
关肺，则不咳而为他病矣。夫脾气散水谷之精，上归于肺，水精四布，下输膀胱者，久咳肺气伤，不能分布水
精，随气上逆，故多涕唾而面浮肿气逆也。
黄帝问：如何区分它们呢？岐伯回答：肺咳的症状，是咳嗽并伴有喘息声，严重时甚至咳出血液；心咳的症状，是咳嗽时心痛，喉咙里感觉像卡着东西一样难受，严重时咽喉肿痛、喉部闭塞不通；肝咳的症状，是咳嗽时两侧胁肋下疼痛，严重时身体不能转动，一转动两侧胁肋下就胀满不适；脾咳的症状，是咳嗽时右侧胁肋下疼痛，疼痛牵引至肩背，严重时不能活动，一动则咳嗽加剧；肾咳的症状，是咳嗽时腰部和背部相互牵引而痛，严重时咳出涎沫。
五脏所在的部位不同，经脉气血运行也各不相同，所以它们受邪气侵袭而导致咳嗽的，各有不同的病症表现，辨别这些症状，才能知道病邪所在之处从而进行治疗。受邪气的脏是病的根本，肺是病的标象，去除其根本，标象自然痊愈，咳嗽即可停止。现在的人只知道治疗肺，难怪疗效不佳。
五脏的久咳不愈，就会传变到六腑。脾咳久治不愈，就会传给胃，胃咳的症状，是咳嗽并呕吐，呕吐严重时蛔虫会吐出；肝咳久治不愈，就会传给胆，胆咳的症状，是咳嗽并呕吐胆汁；肺咳久治不愈，就会传给大肠，大肠咳的症状，是咳嗽并大便失禁；心咳久治不愈，就会传给小肠，小肠咳的症状，是咳嗽并放屁，排气与咳嗽同时发生；肾咳久治不愈，就会传给膀胱，膀胱咳的症状，是咳嗽并遗尿；久咳不愈，就会传给三焦（全身水液代谢和气机运行的通道），三焦咳的症状，是咳嗽并腹部胀满，不想饮食。这些病症都是病邪聚集在胃，关联于肺，导致患者多涕唾，并且面部浮肿、气机上逆。
脏病久治不愈就会传变到腑，它们的咳嗽也各有可辨别的症状。长虫，就是蛔虫。胆汁，就是苦水。三焦包裹在脏腑之外，所以病邪最后传变到三焦。而胃又是脏腑之海，肺主一身之气，所以虽然病症发源于各个脏腑，但必然都会聚集在胃，关联于肺，这才形成咳嗽病，如果不关联肺，就不会咳嗽而是其他疾病了。脾的气机将水谷的精微散布，向上归于肺，水精四布，向下输送到膀胱，这是正常生理。久咳损伤肺气，不能分布水精，水液随气机上逆，所以出现多涕唾、面部浮肿和气逆的症状。
Huangdi asked: How can they be distinguished? Qibo replied: The manifestations of Lung Cough (Fei Ke) include coughing with wheezing and audible sounds, and in severe cases, expectoration of blood. The manifestations of Heart Cough (Xin Ke) include heart pain upon coughing, a sensation of obstruction in the throat as if something were stuck, and in severe cases, sore throat and throat obstruction (Hou Bi). The manifestations of Liver Cough (Gan Ke) include pain under both hypochondria upon coughing, inability to turn the body in severe cases, and fullness under both hypochondria when turning. The manifestations of Spleen Cough (Pi Ke) include pain in the right hypochondrium upon coughing, radiating to the shoulder and back, inability to move in severe cases, and exacerbation of cough upon movement. The manifestations of Kidney Cough (Shen Ke) include pulling pain between the lower back and waist upon coughing, and expectoration of saliva in severe cases.
Since the locations of the five Zang organs differ and their meridians circulate differently, the specific symptoms vary depending on which organ is affected by pathogenic factors. By distinguishing these symptoms, one can identify the location of the pathogen and treat accordingly. The affected Zang organ is the root (Ben), while the Lung is the branch (Biao). Eliminating the root leads to the resolution of the branch and cessation of the cough. It is no wonder that modern practitioners who only treat the Lung often fail to achieve efficacy.
Chronic cough of the five Zang organs may transmit to the six Fu organs. If Spleen Cough persists, it transmits to the Stomach; the manifestation of Stomach Cough (Wei Ke) includes coughing with vomiting, and in severe cases, expulsion of roundworms (Chang Chong). If Liver Cough persists, it transmits to the Gallbladder; the manifestation of Gallbladder Cough (Dan Ke) includes coughing with vomiting of bile. If Lung Cough persists, it transmits to the Large Intestine; the manifestation of Large Intestine Cough (Da Chang Ke) includes coughing with involuntary defecation. If Heart Cough persists, it transmits to the Small Intestine; the manifestation of Small Intestine Cough (Xiao Chang Ke) includes coughing with flatus, where gas loss occurs simultaneously with coughing. If Kidney Cough persists, it transmits to the Bladder; the manifestation of Bladder Cough (Pang Guang Ke) includes coughing with urinary incontinence. If chronic cough persists, it transmits to the San Jiao (Triple Burner); the manifestation of San Jiao Cough (San Jiao Ke) includes coughing with abdominal fullness and loss of appetite. All these conditions involve pathogenic accumulation in the Stomach and involvement of the Lung, causing excessive phlegm and saliva, facial edema, and rebellious Qi.
When Zang diseases persist, they transmit to the Fu organs, and their respective coughs present distinguishable symptoms. "Chang Chong" refers to roundworms. Bile is bitter fluid. The San Jiao envelops the exterior of the Zang and Fu organs, hence the disease transmits to the San Jiao last. The Stomach is the sea of the Zang and Fu organs, and the Lung governs the Qi of the whole body. Therefore, although the disease originates in various Zang and Fu organs, it inevitably accumulates in the Stomach and involves the Lung to form a cough. If it did not involve the Lung, it would not cause cough but other diseases. Normally, the Spleen's Qi scatters the essence of food and drink upward to the Lung, where fluids are distributed throughout the body and transported downward to the Bladder. Chronic cough damages Lung Qi, impairing its ability to distribute fluids; thus, fluids follow the rebellious Qi upward, resulting in excessive phlegm and saliva, facial edema, and rebellious Qi.
