生生子曰∶《内经》云∶“诸气愤郁，皆属于肺。”诸满
喘呕，亦属于肺，以肺主气者也。诸喘气逆者，乃阳火急数而然也。一呼一吸为一息，呼随阳出，吸随阴
入，呼吸之间，脾受其气，通乎营卫，合乎阴阳，热则息急气粗，寒则息迟气微。今之喘逆，由火热而息
急也，或六淫所伤，七情所感，或脾肾俱虚，或脾湿肿满，或本脏气虚，或瘀血伤滞，皆所以致之，要当
合脉认病，合病制方，庶无差失之患矣。
又曰∶方书有云治喘嗽者，有云治痰喘者，有云治喘逆气急者，有云气喘者，不可不分别明白，究治
此病，虚实攸系匪轻。验今之喘嗽者，既嗽而兼有喘声也。痰喘者，喉中有痰，或出或不能出，抬肩撷项
者是也。喘逆气急者，无痰嗽而独气急作喘声也。气喘者，较逆急势则稍缓耳。前二者，兼痰兼嗽，盖有
杂症以干之，故治有汗吐下之不同也，后二者，乃本脏气虚，或阴虚火动，及产后喘急者，为孤阳几于飞
越，治惟补之、敛之。攻补之不同，由虚实之异路也；少有差忒，则轻者重，重者死矣。予于喘嗽二病，
寻究端倪，会类治法，逐证填方，不以重复自嫌，其间搜集不尽者，将俟后之明敏，藉此为左券云尔。
喘而无汗者，宜解表。
喘而有汗者，宜和营卫，固腠理。
腹满，脉沉实者，为内实，当下之。
发时有痰吐出者，宜化痰。
发时有痰不能出者，宜开提之。
食积痰逆者，宜导痰运脾。
饮水多者，宜渗利之。
久嗽不已，痰壅胸膈气实者，宜吐之。
心火形肺者，宜清心热。
气从小腹上冲，乃冲脉之火，宜调中益气汤加黄柏、知母以降之。
脉数无力者，宜滋阴降火。
产后喘急者，郭氏谓孤阳绝，阴极，为难治。
本脏气虚及久喘，攻击太过者，宜人参、五味、阿胶之类补之。
新喘气实者，宜葶苈、枳壳、桑皮之类泻之。
肿满脾虚，不能摄水，上迫于肺，喉中作水鸡声者，或小青龙汤，或导水丸，桑皮、赤小豆、瞿麦之
类决之。瘀血凝滞胸膈者，或韭汁之类以活之。
Shengshengzi said: The *Huangdi Neijing* (Yellow Emperor's Inner Canon) states, "All conditions of qi stagnation and depression belong to the Lung." All conditions of fullness, wheezing, and vomiting also belong to the Lung, because the Lung governs qi. Conditions of wheezing with rebellious qi are caused by urgent and rapid yang-fire. One exhalation and one inhalation constitute one breath; exhalation follows the outward movement of yang, and inhalation follows the inward movement of yin. Between breathing, the Spleen receives this qi, connecting Ying and Wei (nutritive and defensive qi), and harmonizing with yin and yang. In heat, respiration is rapid and coarse; in cold, respiration is slow and faint. Current cases of wheezing and rebellious qi are due to fire-heat causing rapid respiration. These may be caused by injury from the Six Excesses (Wind, Cold, Summerheat, Dampness, Dryness, Fire), induction from the Seven Emotions (Joy, Anger, Worry, Pensiveness, Grief, Fear, Fright), deficiency of both Spleen and Kidney, dampness-swelling due to Spleen dysfunction, deficiency of qi in the Lung itself, or damage and stasis from blood stasis. These are all causes. It is essential to combine pulse diagnosis with disease identification and formulate prescriptions according to the disease, so as to avoid medical errors.
It is further stated: Medical texts mention treating "wheezing with cough," "phlegm-wheezing," "wheezing with rebellious and rapid qi," and "asthma-like breathing." These must be clearly distinguished. Investigating the treatment of this disease depends significantly on distinguishing excess and deficiency, which is not a minor matter. Verifying current cases of "wheezing with cough": it involves both coughing and wheezing sounds. "Phlegm-wheezing": there is phlegm in the throat, sometimes expectorated, sometimes not, characterized by raising shoulders and pulling the neck. "Wheezing with rebellious and rapid qi": there is no phlegm or cough, only rapid qi producing wheezing sounds. "Asthma-like breathing" is slightly milder in intensity compared to rebellious and rapid qi. The former two involve phlegm and cough, likely complicated by other disorders interfering, thus treatments differ using sweating, emesis, or purging methods. The latter two result from deficiency of qi in the organ itself, or yin-deficiency with fire hyperactivity, and postpartum acute wheezing, representing solitary yang nearly flying away; treatment should solely focus on tonification and astringency. The difference between attacking and tonifying methods stems from the different pathways of excess and deficiency; even slight deviations can turn mild cases severe and severe cases fatal. Regarding the diseases of wheezing and cough, I have investigated their origins, categorized treatment methods, and matched prescriptions to each syndrome, without shying away from repetition. For those not fully collected here, I leave them for future scholars to verify and utilize.
For wheezing without sweat, exterior-releasing is appropriate.
For wheezing with sweat, harmonizing Ying and Wei and consolidating the Couli (pores) is appropriate.
For abdominal fullness with a deep, forceful pulse, indicating interior excess, purgation is appropriate.
When attacks occur with expectorated phlegm, resolving phlegm is appropriate.
When attacks occur with phlegm that cannot be expectorated, lifting and opening the lungs is appropriate.
For food stagnation leading to rebellious phlegm-qi, guiding phlegm and moving the Spleen is appropriate.
For excessive water intake, promoting diuresis is appropriate.
For chronic cough persisting with phlegm obstructing the chest/diaphragm and excess qi, emesis is appropriate.
For Heart fire insulting the Lung, clearing Heart heat is appropriate.
For qi rushing upward from the lower abdomen, attributed to Fire of the Chong Mai (Penetrating Vessel), Tiaozhong Yiqi Tang (Regulate Middle Qi-Decoction) plus Huangbai (Phellodendri Cortex) and Zhimu (Anemarrhenae Rhizoma) should be used to descend qi.
For a rapid but weak pulse, nourishing yin and descending fire is appropriate.
For postpartum acute wheezing, Guo Shi considered it a condition of solitary yang extinction and extreme yin, making it difficult to treat.
For deficiency of qi in the organ itself and chronic wheezing caused by excessive attacking methods, tonification with Ren Shen (Ginseng Radix et Rhizoma), Wu Wei Zi (Schisandrae Fructus), and E Jiao (Colla Corii Asini) is appropriate.
For new-onset wheezing with excess qi, purging with Ting Li Zi (Semen Lepidii seu Descurainiae), Zhi Ke (Aurantii Fructus Immaturus), and Sang Bai Pi (Mori Cortex) is appropriate.
For swelling and fullness due to Spleen deficiency failing to control water, with water qi pressing upward on the Lung, producing a sound like a water-frog in the throat, Xiao Qing Long Tang (Minor Blue Dragon Decoction) or Dao Shui Wan (Guide Water Pill), or Sang Bai Pi, Chi Xiao Dou (Adzuki Bean), and Qu Mai (Polygoni Avicularis Herba) can be used to drain water. For blood stasis coagulating in the chest/diaphragm, Jiuzhi (Allium Tuberosum Juice) or similar agents can be used to invigorate blood.
