齐氏云∶肺痈肺痿，因脾肺气虚，腠理不密，外邪所乘；或母食辛辣浓味，遗热于儿；或儿有病过于汗下，内亡津
液，虚火烁肺；或服克伐之药，亏损脾胃，不能生肺金。其症恶风咳嗽，鼻塞项强，呼吸不利，甚则四肢微肿，咳唾脓
血。若吐臭秽，胸中隐痛，脉数而实者为肺痈；咳唾涎沫，脉数而虚者为肺痿。恶寒喘嗽者，寒邪内蕴也，小青龙汤。
咳唾脓秽者，肺痈内溃也，桔梗汤。窃谓前症若喘咳短气者，脾胃气虚也，五味异功散。咳唾脓痰，左尺脉数而无力者，
肾气虚也，六味地黄丸。咳唾脓痰，右关脉数而无力者，脾气虚也，七味白术散。若发热喘嗽，唾脓不食者，脾肺虚甚
也，难治。大要补脾肺、滋肾水为善。仍审五脏相胜，乳母七情。后症仿此。
一小儿感冒停食吐泻，用疏利之剂，咳嗽脓血，此中气复伤而变肺痈也，用桔梗汤而愈。后咳嗽吐血，仍用前药，
佐以异功散而痊。
一小儿停食，服泻药而变肺痈，余先用异功散以救脾肺，次用桔梗汤以治肺痈而瘥。
一小儿停食，服克伐之药，唾痰腥气，面赤气喘，此元气复伤而成肺痈也，用桔梗汤，脓痰顿止。翌日喘甚，此脾
气虚而不能生肺也，用异功散加杏仁、百合而愈。后小便涩滞，服八正散，小便愈涩，咳嗽吐痰，面赤盗汗，余谓肺气
虚热，前药亏损真阴，虚火烁肺金而然。用异功散以补脾土，地黄丸以滋肾水，遂愈。
一小儿肺痈，愈后咳嗽，面色白或痿黄，手足冷，小便频，此因脾虚不能生金也，服参苏饮之类，自汗盗汗，昏愦
发搐，遗尿下气，手足如冰，面色青白，此阳气脱而虚寒也，用人参一两、干姜二钱、大枣五枚，米泔煎沸，先灌一杯，
将熟又灌二杯，连用二剂而苏。更朝用补中益气汤，夕用异功散而愈。
一小儿十五岁，因劳伤元气而咳嗽，误用表散之剂，复伤肺气成痈，咳嗽脓血，用桔梗汤为主，佐以异功散，脓渐
少，专用异功散，脓止而愈。后因书课过劳，自汗时嗽，服外感药，咳嗽益甚，胸膈痞满，呼吸不利。余谓脾肺之气虚
甚而然，用参 补脾汤而痊。
一小儿咳嗽，服参苏饮而益甚，右寸之关脉浮散，余谓∶此风伤皮毛，热伤血脉，血气羁留蕴结于肺而成痈也。不
信，乃服表散，唾咳脓血。余曰∶此因肺虚不能摄气，脾虚不能摄涎耳，当补脾土以生肺金。又不信，果殁。
一小儿感冒咳嗽，发散过度，喘促不食，痰中有血，余用桔梗汤而愈。后元气未复，大便似痢，或用芩、连、枳实
之类，变慢脾风而卒。
小青龙汤 治伤风冒寒，咳嗽喘急，肺胀胸满，鼻塞流涕，或干呕热咳，或作喝，或作噎，或小便不利，或小
腹胀满。（此仲景之法，审有是症，用之及时，殊有良验。）

Qi Shi said: Lung abscess (Fei Yong) and lung atrophy (Fei Wei) are caused by Qi deficiency of the Spleen and Lung, with loose interstices (skin pores and muscle intervals), allowing external pathogens to invade; or due to the mother consuming spicy and rich foods, transmitting heat to the child; or due to excessive sweating and purging during the child's illness, leading to internal loss of body fluids, with deficient fire scorching the lungs; or from taking harsh drugs that damage the Spleen and Stomach, preventing them from generating Lung Metal. The symptoms include aversion to wind, cough, nasal congestion, stiffness of the neck, difficult breathing, and in severe cases, slight swelling of the four limbs, and coughing up pus and blood. If foul-smelling sputum is expectorated, accompanied by dull chest pain and a rapid, forceful pulse, it is a lung abscess; if saliva-like foam is expectorated with a rapid, empty pulse, it is lung atrophy. Aversion to cold, wheezing, and cough indicate internal retention of cold pathogen, treated with Xiao Qing Long Tang (Minor Blue Green Dragon Decoction). Expectorating pus and foul matter indicates internal ulceration of the lung abscess, treated with Jie Geng Tang (Platycodon Decoction). I believe that for the aforementioned conditions, if there is wheezing, cough, and shortness of breath, it is Spleen-Stomach Qi deficiency, treated with Wu Wei Yi Gong San (Five-Ingredient Powder for Extraordinary Merit). Expectorating pus and phlegm with a rapid but weak left Chi pulse indicates Kidney Qi deficiency, treated with Liu Wei Di Huang Wan (Six-Ingredient Pill with Rehmannia). Expectorating pus and phlegm with a rapid but weak right Guan pulse indicates Spleen Qi deficiency, treated with Qi Wei Bai Zhu San (Seven-Ingredient Powder of Atractylodes Macrocephala). If fever, wheezing, cough, expectoration of pus and blood, and anorexia occur, it indicates extreme deficiency of Spleen and Lung, which is difficult to treat. Generally, tonifying Spleen and Lung and nourishing Kidney Water is beneficial. One must also examine the mutual overcoming relationships among the Five Zang organs and the emotional states of the nursing mother. Subsequent conditions should be handled similarly.
A child suffered from cold and food stagnation with vomiting and diarrhea. After using draining and regulating agents, he developed cough with pus and blood. This was due to further injury of Middle Qi transforming into lung abscess, cured with Jie Geng Tang. Later, cough with hemoptysis occurred; the previous medicine was used again, assisted by Yi Gong San, resulting in recovery.
A child had food stagnation and developed lung abscess after taking purgatives. I first used Yi Gong San to rescue Spleen and Lung, then used Jie Geng Tang to treat the lung abscess, leading to recovery.
A child had food stagnation and took harsh drugs, resulting in expectoration of fishy-smelling sputum, red face, and asthma. This was due to further injury of Yuan Qi forming lung abscess. Jie Geng Tang was used, and pus-phlegm stopped immediately. The next day, asthma worsened, indicating Spleen Qi deficiency failing to generate Lung Metal. Yi Gong San added with Xing Ren (Apricot Seed) and Bai He (Lily Bulb) cured him. Later, dysuria occurred. Ba Zheng San was taken, worsening the dysuria, accompanied by cough, sputum, red face, and night sweats. I diagnosed this as Lung Qi deficiency with heat, where previous drugs damaged True Yin, and deficient fire scorched Lung Metal. Yi Gong San was used to tonify Spleen Earth, and Di Huang Wan to nourish Kidney Water, leading to recovery.
A child recovered from lung abscess but continued to cough, with pale or sallow complexion, cold hands and feet, and frequent urination. This was due to Spleen deficiency failing to generate Metal. Taking Shen Su Yin led to spontaneous sweating, night sweats, dizziness, convulsions, enuresis, and fecal incontinence. Hands and feet became ice-cold, and the complexion turned blue-white, indicating Yang Qi collapse with deficiency cold. Ren Shen (Ginseng) 1 liang, Gan Jiang (Dried Ginger) 2 qian, and Da Zao (Jujube) 5 pieces were decocted in rice wash water. One cup was administered first, followed by two cups when nearly done. Two doses restored consciousness. Bu Zhong Yi Qi Tang was taken in the morning, and Yi Gong San in the evening, leading to recovery.
A fifteen-year-old child developed cough due to labor injuring Yuan Qi. Misuse of diaphoretic agents further injured Lung Qi, causing abscess with cough and pus-blood. Jie Geng Tang was used as the main formula, assisted by Yi Gong San. Pus decreased gradually. Using only Yi Gong San stopped the pus and cured the condition. Later, overwork from studying led to spontaneous sweating and occasional cough. External pathogen medicines were taken, worsening the cough, with chest oppression and difficult breathing. I diagnosed this as extreme deficiency of Spleen and Lung Qi. Can Shen Bu Pi Tang cured him.
A child coughed, and the condition worsened after taking Shen Su Yin. The Right Cun and Guan pulses were floating and scattered. I stated: Wind injured the skin and hair, heat injured the blood vessels, causing Qi and Blood to stagnate and accumulate in the Lung, forming an abscess. Disbelieving, he took diaphoretics, resulting in expectoration of pus and blood. I said: This is because Lung deficiency fails to grasp Qi, and Spleen deficiency fails to control saliva. Tonifying Spleen Earth to generate Lung Metal is required. Disbelieving again, he died.
A child had cold-induced cough. Over-diaphoresis led to panting, anorexia, and blood in sputum. Jie Geng Tang cured him. Later, with incomplete recovery of Yuan Qi, stool resembled dysentery. Someone used Huang Qin (Scutellaria Root), Huang Lian (Coptis Rhizome), and Zhi Shi (Immature Bitter Orange), leading to Man Pi Feng (Slow Spleen Wind) and sudden death.
Xiao Qing Long Tang treats wind-cold invasion, cough with urgent wheezing, lung distension and chest fullness, nasal congestion with runny nose, dry retching with hot cough, hiccups, choking, difficulty urinating, or lower abdominal fullness. (This is Zhang Zhongjing's method. When these symptoms are present and used timely, it yields excellent results.)
