暑咳之为病，独在暑月也。良由暑热下逼，先伤乎上，夫五脏之位，惟肺最高，为诸脏之华盖，暑
热袭之，肺经先病者，固无论矣。且暑中有火，肺体属金，火未有不克金者也。其脉濡滑而数，两寸有力
而强，咳逆乏痰，即有亦少，或身热口渴，或胸闷胁痛，此皆暑热入肺之脉证也，宜用清宣金脏法加滑
石、甘草治之。如痰多者，不因暑而因湿，不名咳而名嗽，不在肺而在脾，不用清而用温。果因痰而致嗽者，
宜用加味二陈法治之。倘不细辨，以暑为湿，误用温药，扰动其络，络中血沸，而成吐血之 ，然则宜用却暑
调元法去东参、半夏，加杏仁、花粉、旱莲、生地治之。大概总宜清暑保金，庶不至蔓延虚损耳。
暑瘵者，骤然吐血衄血，头目不清，烦热口渴，咳嗽气喘，
脉象浮取则洪，中取则空，沉取复有。此因盛夏之月，相火用
事，火烁肺金，复燃阳络，络血上溢所致。昧者以为痨瘵，殊不知火载血上，非真阴亏损而为虚痨者比也。
当清暑热以保肺，清络热以止血。如初起体实者，宜以清宣金脏法加枯芩、黑栀治之。体弱者，宜以却暑调
元法去石膏、半夏、粳米，加鲜地、鲜斛、鲜藕节治之。如未止，再加丹皮、旱莲草可也。虽非痨
瘵之病，但失血后有潮热咳嗽之证，小数之脉，其阴分不亏亦亏，又当以甘咸养阴法治之，倘蹉跎失治，
伤及真阴，遂难疗矣。
暑咳这种病，只发生在夏季。这主要是因为暑热之气向下逼迫，首先损伤上部。在五脏的位置中，只有肺最高，是各脏器的华盖（保护罩），暑热侵袭它，肺经先发病，这是理所当然的。况且暑气中包含火邪，肺体属金，火没有不克制金的道理。其脉象濡滑而数，两寸脉有力且强盛，咳嗽气逆且痰少，即使有痰也很少，或者身体发热口渴，或者胸闷胁痛，这些都是暑热入肺的脉证表现，适宜使用清宣金脏法加滑石、甘草来治疗。如果痰多的情况，不是因为暑而是因为湿，不能称为咳而应称为嗽，病位不在肺而在脾，治疗方法不应清热而应温化。确实是因为痰导致咳嗽的，适宜使用加味二陈汤来治疗。如果不仔细辨别，将暑误认为湿，错误地使用温药，扰动络脉，导致络中血液沸腾，从而形成吐血的病症，这时适宜使用却暑调元法去掉东参、半夏，加入杏仁、花粉、旱莲草、生地来治疗。大抵总宜清解暑热以保全肺气，这样才不至于蔓延成虚损之症。
暑瘵这种病，表现为突然吐血或鼻衄，头目昏沉不清，烦热口渴，咳嗽气喘，脉象轻取则洪大，中取则空虚，重取又复现。这是因为盛夏时节，相火当令，火热灼伤肺金，又点燃阳络，导致络中血液上溢所致。庸医误以为是痨瘵（慢性消耗性疾病），殊不知这是火载血上行，并非真正的阴液亏损导致的虚劳，不可同日而语。应当清解暑热以保肺，清解络热以止血。如果是初起体质壮实者，适宜用清宣金脏法加枯芩、黑栀来治疗。体质虚弱者，适宜用却暑调元法去掉石膏、半夏、粳米，加入鲜地黄、鲜石斛、鲜藕节来治疗。如果出血未止，再加丹皮、旱莲草即可。虽然这不是痨瘵之病，但在失血后出现潮热咳嗽的症状，脉象细数，此时即便阴分原本不亏也会变得亏损，又应当使用甘咸养阴法来治疗，如果拖延失治，伤及真阴，就难以治愈了。
Shu Ke (Summerheat Cough) is a disease that occurs exclusively during the summer months. This is primarily due to summer-heat and fire pathogens forcing downward, damaging the upper jiao first. Among the five zang organs, the Lung is positioned highest, serving as the "Canopy" (Huagai, 华盖) protecting all other organs. When summer-heat attacks it, it is inevitable that the Lung meridian becomes diseased first. Moreover, summer-heat contains fire; since the Lung belongs to Metal in the Five Elements, Fire inevitably overcomes Metal. The pulse is soggy, slippery, and rapid; the cun positions on both wrists are forceful and strong. There is coughing with rebellious qi and scanty sputum, or even no sputum at all. Symptoms may include fever, thirst, chest tightness, and hypochondriac pain. These are the pulse and symptom manifestations of summer-heat entering the Lung. It is appropriate to use Qing Xuan Jin Zang Fa (Clear and Disperse the Metal Organ Method) plus Hua Shi (Talcum, Talcum Glaucescens) and Gan Cao (Licorice Root, Glycyrrhizae Radix et Rhizoma) for treatment. If there is excessive sputum, it is not caused by summer-heat but by dampness; it should be named Sou (Phlegm-rheum cough) rather than Ke (Cough); the pathology lies in the Spleen rather than the Lung; and the treatment method should be warming rather than clearing. If the cough is indeed caused by phlegm, Jia Wei Er Chen Tang (Modified Two-Aged Powder) is appropriate. If one fails to distinguish carefully and mistakes summer-heat for dampness, mistakenly using warming herbs, it will disturb the collaterals, causing blood to boil within the collaterals, leading to hematemesis (vomiting blood). In such cases, Que Shu Diao Yuan Fa (Eliminate Summerheat and Regulate Primordial Qi Method) should be used, removing Dong Shen (Asiatic Solomon's Seal Rhizome, Glehniae Radix) and Ban Xia (Pinellia Tuber, Pinelliae Rhizoma), and adding Xing Ren (Apricot Seed, Armeniacae Semen Amarum), Hua Fen (Trichosanthes Root, Trichosanthis Radix), Han Lian Cao (Eclipta Herb, Ecliptae Herba), and Sheng Di Huang (Rehmannia Root, Rehmanniae Radix). Generally, it is best to clear summer-heat and protect the Lung metal, so as to prevent the condition from spreading into deficiency consumption.
Shu Zhai (Summerheat Tuberculosis-like Hemorrhage) presents with sudden hematemesis or epistaxis, cloudiness of the head and eyes, irritability, heat, thirst, cough, and wheezing. The pulse is surging when lightly palpated, empty when moderately palpated, and reappears when deeply palpated. This is caused by the ministerial fire being active during midsummer, scorching Lung metal and igniting the Yang collaterals, leading to the upward overflow of collateral blood. Ignorant practitioners mistake this for Lao Zhai (Tuberculosis/Consumption), not realizing that this is blood carried upward by fire, which is fundamentally different from true Yin deficiency consumptive diseases. One should clear summer-heat to protect the Lung and clear collateral heat to stop bleeding. For patients who are physically robust at the onset, Qing Xuan Jin Zang Fa (Clear and Disperse the Metal Organ Method) plus Ku Qin (Scutellaria Root, Scutellariae Radix) and Hei Zhi (Charred Gardenia Fruit, Gardeniae Fructus) is appropriate. For those with weak constitutions, Que Shu Diao Yuan Fa (Eliminate Summerheat and Regulate Primordial Qi Method) should be used, removing Shi Gao (Gypsum Fibrosum, Gypsum), Ban Xia (Pinellia Tuber, Pinelliae Rhizoma), and Jing Mi (Rice, Oryzae Fructus), and adding Xian Di Huang (Fresh Rehmannia Root, Fresh Rehmanniae Radix), Xian Hu (Fresh Dendrobium Stem, Dendrobii Caulis), and Xian Ou Jie (Fresh Lotus Rhizome Node, Nelumbinis Rhizomatis Nodus). If bleeding does not cease, add Mu Dan Pi (Moutan Cortex, Moutan Radicis Cortex) and Han Lian Cao (Eclipta Herb, Ecliptae Herba). Although this is not a tuberculous disease, after hemorrhage, symptoms such as tidal fever and cough may appear, and the fine, rapid pulse indicates that even if the Yin aspect was not previously deficient, it now is. At this stage, Gan Xian Yang Yin Fa (Sweet and Salty Nourishing Yin Method) should be employed. If treatment is delayed, damaging the True Yin, the condition will become difficult to cure.
