肺为华盖，职司整肃。自气逆而为咳，痰动而为嗽。其证之寒热虚实，外因内因，宜审
辨也
。肺寒则嗽必痰稀，面白，畏风多涕，宜温肺固卫。肺热则嗽必痰稠，面红身热，喘满，宜
降火清痰。肺虚则嗽必气逆，汗出，颜白，飧泄，宜补脾敛肺。肺实则嗽必顿咳，抱首，面
赤，反食，宜利膈化痰。外因在六淫，内因在脏腑，亦各有治法，而外治诸法，要不可缓。

肺被称为“华盖”，其职能是维持全身气机的清肃与整饬。气机上逆则引发咳嗽，痰液流动则引发嗽症。对于病症的寒、热、虚、实属性，以及外感或内伤病因，应当仔细辨别。
若肺受寒邪，咳嗽必然伴有稀痰，面色苍白，畏风且鼻涕多，适宜采用温补肺气、巩固卫表的方法。若肺受热邪，咳嗽必然伴有稠痰，面红身热，气喘胸闷，适宜采用降火清热、清除痰浊的方法。若肺气虚弱，咳嗽必然伴有气逆，出汗，面色苍白，完谷不化的泄泻，适宜采用补益脾土、收敛肺气的方法。若肺气壅实，咳嗽必然是阵发性剧烈咳嗽（顿咳），抱头痛苦，面红，反胃呕吐，适宜采用通利胸膈、化解痰浊的方法。
外感病因在于六淫（风、寒、暑、湿、燥、火），内伤病因在于脏腑失调，它们各自有相应的治疗方法，而各种外治法尤其不可延误。
具体操作手法如下：分阴阳（操作二百遍），推三关（操作一百遍），退六腑（操作一百遍），推肺经（操作二百遍），掐二扇门穴（操作二十四遍），掐二人上马穴（操作二十四遍），揉肺俞穴（操作二百遍），掐五指节（操作二十四遍），掐合谷穴（操作二十四遍），运八卦（操作一百遍），揉大指根（操作一百遍），掐精宁穴（操作二十四遍），天门入虎口（操作五十遍）。
若出现痰液壅盛、气喘的症状，加用掐向导穴（操作三十六遍），掐板门穴（操作二十四遍）。若出现痰结阻塞的症状，加用运八卦（操作一百遍）。若是干咳，加用退六腑（操作一百遍）。若是痰咳，加用推肺经、推脾经、清肾水、运八卦（各操作一百遍）。若是气喘，加用飞经走气手法（操作五十遍）。凡使用推拿手法时，均需用葱水作为介质。
按语：先贤曾说，各种疾病容易治疗，唯独咳嗽难以医治。因为咳嗽的病因头绪繁杂。徐洄溪（徐灵胎）历经三十年后才掌握治疗咳嗽的技术，可见治疗咳嗽之难达到如此程度。身为医者，应当如何辨证施治？必须追求百治百效，才不愧为优秀的医生。（惕厉子）
The Lung is referred to as the "Canopy" (Hua Gai), and its function is to maintain the clearing, descending, and regulating of Qi throughout the body. When Qi rebels upward, it causes Ke (cough); when Phlegm moves, it causes Sou (phlegmy cough). The nature of the syndrome—whether Cold, Heat, Deficiency, or Excess—and whether the cause is External or Internal must be carefully differentiated.
If the Lung is affected by Cold, the cough will necessarily be accompanied by thin Phlegm, a pale complexion, aversion to Wind, and excessive nasal discharge; the appropriate treatment is to Warm the Lung and Consolidate the Wei (Defensive) Qi. If the Lung is affected by Heat, the cough will necessarily be accompanied by thick Phlegm, a red face, fever, wheezing, and chest fullness; the appropriate treatment is to Descend Fire, Clear Heat, and resolve Phlegm. If Lung Qi is Deficient, the cough will necessarily be accompanied by rebellious Qi, sweating, a pale face, and undigested food in the stool (Sun Xie); the appropriate treatment is to Tonify the Spleen and Astringe the Lung. If Lung Qi is Excessive/Full, the cough will necessarily be paroxysmal (Dun Ke), with the patient holding their head in pain, a red face, and vomiting after eating; the appropriate treatment is to Benefit the Diaphragm and transform Phlegm.
External causes lie in the Six Evils (Liu Yin: Wind, Cold, Summer-heat, Dampness, Dryness, Fire), while internal causes lie in the Zang-Fu organs; each has its own specific treatment methods, but various external therapy techniques should not be delayed.
Specific manipulation techniques are as follows: Fen Yin Yang (divide Yin and Yang) [200 times], Tui San Guan (push Three Gates) [100 times], Tui Liu Fu (push Six Bowels) [100 times], Tui Fei Jing (push Lung Meridian) [200 times], Qia Er Men Shan (pinch Two Gate Doors) [24 times], Qia Er Ren Shang Ma (pinch Two People Mounting Horses) [24 times], Rou Fei Shu (knead Feishu BL13) [200 times], Qia Wu Zhi Jie (pinch Five Finger Nodes) [24 times], Qia He Gu (pinch Hegu LI4) [24 times], Yun Ba Gua (move Eight Trigrams) [100 times], Rou Da Zhi Gen (knead root of the thumb) [100 times], Qia Jing Ning (pinch Jingning) [24 times], Tian Men Ru Hu Kou (Heaven's Gate enters Tiger's Mouth) [50 times].
If there is Phlegm obstruction and wheezing, add Qia Xiang Dao (pinch Guide) [36 times] and Qia Ban Men (pinch Board Door) [24 times]. If there is Phlegm knotting and blockage, add Yun Ba Gua (move Eight Trigrams) [100 times]. If it is dry cough, add Tui Liu Fu (push Six Bowels) [100 times]. If it is phlegmy cough, add Tui Fei Jing (push Lung Meridian), Tui Pi Jing (push Spleen Meridian), Qing Shen Shui (clear Kidney Water), and Yun Ba Gua (move Eight Trigrams) [each 100 times]. If there is wheezing, add Fei Jing Zou Qi (fly through meridians and move Qi) [50 times]. All pushing manipulations should use Scallion Water as a medium.
Note: Ancient sages stated that various diseases are easy to treat, but cough is difficult to cure. This is because the etiology of cough is complex and multifaceted. Xu Huixi (Xu Lingtai) spent thirty years before he could effectively treat cough, demonstrating how difficult treating cough can be. Physicians must determine how to differentiate syndromes and apply treatments accordingly, striving for hundred-percent efficacy, so as to deserve the title of a skilled practitioner. (Tili Zi)
