凡痈疽毒疮，发热有时，晡甚旦止。若夏月间，有头面外项赤肿，或咽喉肿痛，或腿足掀肿，长至数寸，不能动
履，人皆疑为疮，但其头痛内燥，昼夜发热不止，自与疮证不同。但以败毒散加石膏、黄连等药，热证一解，赤肿
自消，全无脓血，此名暑疡，毫厘而千里者也。
霖按∶暑疡一证，热胜者红肿坚痛，风胜者则痒，湿胜者多脓水。治宜清达泄热，消风祛湿，当权其微甚以消息之。
盛暑之月，火能灼金，若不禁辛酒，脾火暴甚，有劳热燥扰，而火动于心肺者，令人咳嗽气喘，骤吐血衄血，头
目不清，胸膈烦 不宁，即童稚老夫，间一病此，昧者以为劳瘵，不知火在血上，非真阴亏损而虚劳者等也。宜四
物汤、黄连解毒、二陈汤三药内，去川芎、白芍、黄柏，以贝母易半夏，加桔梗以抑之，薄荷以散之，麦冬、五味以
敛之，自愈。或加童便、藕汁，或黄连香薷饮一二剂亦可。静摄数日，忌酒煎炒自安，是名暑瘵，宜酌而善用焉，或
用东垣参苓调中亦妙。
霖按∶暑瘵乃阴气不生，阳气不潜，证见咳血吐血，日晡烦蒸，早间清爽，舌白口渴，头胀身疼、皆暑热之邪内袭，
阴劫络伤，虽有宿恙，亦当先清络热。宜沙参、甜杏仁、川贝、蒌皮、连翘、麦冬、竹叶、鲜生地等味，鲜荷叶汁
一杯和服，尤有奇功。俟血止后，再议育阴。若先后失序，或误用温补，则络中伏热不得外达，必成不治之证。医见舌
苔白，多疑伏寒，未敢迳用清凉，因循贻误者有之，不知舌苔白乃暑邪伤气，肺主气属金，金色白故也。
凡是痈疽毒疮，发热有定时，傍晚加重，早晨停止。如果在夏季，出现头面、后颈红肿，或者咽喉肿痛，或者腿足肿胀隆起，长达数寸，不能行走活动，人们都怀疑是疮疡，但是伴有头痛、体内燥热，昼夜发热不停，这自然与疮证不同。只需使用败毒散加入石膏、黄连等药物，热证解除后，红肿自然消退，完全没有脓血，这叫做暑疡，（看似相似实则）毫厘之差却导致千里之谬。
霖按：暑疡这一病证，热邪盛则红肿坚硬疼痛，风邪盛则瘙痒，湿邪盛则多脓水。治疗应当清透泄热，祛风除湿，需要根据病情的轻重来斟酌处理。
盛夏月份，火邪能灼伤肺金，如果不忌口辛辣和酒类，脾火突然亢盛，产生劳热燥扰，火热扰动心肺，使人咳嗽气喘，突然吐血或鼻出血，头目昏沉不清，胸膈烦闷不宁，即使是儿童老人，偶尔患病于此，庸医误认为是虚劳病（劳瘵），不知道这是火在血分之上，并非真阴亏损导致的虚劳。适宜用四物汤、黄连解毒汤、二陈汤三种方剂中，去掉川芎、白芍、黄柏，用贝母代替半夏，加入桔梗以制约，薄荷以疏散，麦冬、五味子以收敛，即可自愈。或者加入童便、藕汁，或者服用一两剂黄连香薷饮也可以。静养数日，忌食酒、煎炸食物，自然安宁，这叫做暑瘵，应当斟酌并善于运用，或者使用东垣的参苓调中散也很好。
霖按：暑瘵是由于阴气不生发，阳气不潜藏，症状表现为咳血吐血，傍晚时分烦热蒸腾，早晨清爽，舌苔白且口渴，头胀身疼，这都是暑热邪气内袭，阴液被劫夺、络脉受损所致，即使有旧疾，也应当先清除络脉中的热邪。适宜使用沙参、甜杏仁、川贝、瓜蒌皮、连翘、麦冬、竹叶、鲜生地等药材，用一杯鲜荷叶汁调和服用，尤其有奇效。等到血止住后，再商议滋养阴液的方法。如果步骤顺序颠倒，或者误用温补药物，那么络脉中潜伏的热邪就不能向外发散，必然成为不治之症。医生见到舌苔白，多怀疑是伏寒，不敢直接使用清凉药物，因循守旧贻误病情的人有之，不知道舌苔白乃是暑邪损伤正气，肺主气属金，金色白的原因。
Whenever there are carbuncles, ulcers, or toxic sores, fever occurs at specific times, worsening in the late afternoon and subsiding in the morning. If during the summer months, there is redness and swelling on the head, face, and back of the neck, or sore throat and swelling, or severe swelling of the legs and feet extending several inches, making walking impossible, people often suspect it to be a sore. However, accompanied by headache and internal dryness/heat, with continuous fever day and night, it naturally differs from typical sore conditions. By using Baidu San (Decoction for Defeating Toxins) added with Shigao (Gypsum Fibrosum), Huanglian (Coptidis Rhizoma), and other herbs, once the heat syndrome resolves, the redness and swelling will subside spontaneously, with absolutely no pus or blood. This is named Shuyang (Summer-Heat Carbuncle), where a difference of a hair's breadth leads to an error of a thousand miles.
Lin's Commentary: In the syndrome of Shuyang, when Heat pathogen prevails, there is redness, swelling, hardness, and pain; when Wind pathogen prevails, there is itching; when Dampness pathogen prevails, there is abundant pus and discharge. Treatment should focus on clearing and venting to drain heat, dispelling wind and removing dampness, adjusting according to the severity of the condition.
In the height of summer, Fire can scorch Metal (Lung). If one does not abstain from pungent foods and alcohol, Spleen Fire may surge violently, causing labor-like heat and dryness disturbing the organs, stirring up Fire in the Heart and Lungs. This causes coughing, wheezing, sudden hematemesis (vomiting blood) or epistaxis (nosebleed), cloudiness of the head and eyes, and restlessness and irritability in the chest and diaphragm. Even if children or the elderly occasionally suffer from this, ignorant practitioners mistake it for Laozhi (Consumption/Tuberculosis). They do not realize that the Fire is above the Blood, which is not equivalent to deficiency consumption caused by depletion of True Yin. It is suitable to use Siwu Tang (Four Substances Decoction), Huanglian Jiedu Tang (Coptis Decoction for Resolving Toxicity), and Erchen Tang (Two Aged Herbs Decoction). From these three formulas, remove Chuanxiong (Cyperi Rhizoma), Baishao (Paeoniae Radix Alba), and Huangbai (Phellodendri Cortex); replace Banxia (Pinelliae Rhizoma) with Beimu (Fritillariae Bulbus); add Jiegeng (Platycodonis Radix) to restrain, Bohe (Menthae Haplocalycis Herba) to disperse, Maidong (Ophiopogonis Radix) and Wuweizi (Schisandrae Fructus) to astringe, and self-healing will occur. Alternatively, add Tongbian (Urine of Child) or Ouji (Nelumbinis Nuciferae Rhizoma Juice), or take one or two doses of Huanglian Xiangru Yin (Coptis and Elsholtzia Drink). Rest quietly for several days, avoid alcohol and fried foods, and peace will return. This is named Shuzhai (Summer-Heat Consumption), which should be considered and applied wisely. Using Dongyuan's Shenling Tiaozhong San (Ginseng and Atractylodes Powder for Regulating the Middle) is also excellent.
Lin's Commentary: Shuzhai arises because Yin Qi fails to generate and Yang Qi fails to hide. Symptoms include hemoptysis and hematemesis, feeling hot and irritable in the late afternoon, clarity in the morning, white tongue coating with thirst, head distension, and body ache. These are all due to Summer-Heat pathogenic factors invading internally, depleting Yin and damaging collaterals. Even if there are chronic ailments, one must first clear the heat in the collaterals. Suitable herbs include Shashen (Glehniae Radix), Tian Xingren (Sweet Apricot Seed), Chuan Bei (Fritillariae Cirrhosae Bulbus), Loupi (Trichosanthis Pericarpium), Lianqiao (Forsythiae Fructus), Maidong (Ophiopogonis Radix), Zhuye (Bambusae Folium), and Xian Shengdi (Rehmanniae Radix Recens). Mix with one cup of Xian Heye Zhi (Fresh Lotus Leaf Juice) for administration, which yields remarkable results. After bleeding stops, discuss nourishing Yin. If the sequence is reversed, or if warming and tonifying herbs are mistakenly used, the latent heat in the collaterals cannot reach the exterior, inevitably becoming an incurable condition. Physicians seeing a white tongue coating often suspect latent Cold and dare not directly use cooling herbs, leading to delays and errors. They fail to understand that a white tongue coating is due to Summer-Heat damaging Qi; the Lung governs Qi and belongs to Metal, and the color of Metal is white.
