疹瘰发热恶寒，胸闷腹痛，烦热欲呕，此邪郁肺
胃。宜用杏仁，桔梗、枳壳、郁金，淡豆豉，黑山
栀，薄荷，大力、苍耳、连翘等味，轻扬宣肺也。
疹为肺经风热，瘰为胃中湿热。故疹粒细而如蚊迹，现
于皮面，粒大而如钱样，附于肌肉。以肺主皮毛，胃主肌
肉也。期必先胸膈满闷，腹中绞痛，此由风热壅遏，气机
不宜，甚面呕吐不休。然疹瘰而得吐泻，正郁遏之邪得以疏
泄，不必止之。故用杏仁、郁金、积壳、桔梗开上焦，山
栀、淡豉祛郁积，薄荷、大力祛风，连翘、苍耳化热，则邪
透瘰自解焉。
疹瘰或隐或现，搔痒无度，此风热内蒸。宜用薄
荷、大力、黄连、黄芩，荆芥、防风、蝉衣、丹皮、
连翘、黑山栀、杏仁、地肤子等味，清热祛风也。
疹瘰既现，时或隐伏，遍身搔痒，良由风热蕴结，气血
不清，故用酒炒芩、连，合连翘、黑栀清火，薄荷、大力、
防风、荆芥祛风，蝉衣、丹皮，杏仁，地肤两清气血，则热
清而疹自化焉。
白瘖末见，发热身痛，面色晦滞，舌苔粘腻，胸
腕不爽，呕恶便溏，脉大而缓，此热蕴蒸。宜用黄
连温胆汤加杏仁、蒌皮、通草、豆卷等昧，通泄三焦
也。
瘖之初发，必由湿热化蒸，气分不清。盖湿必阻气，热
亦伤气。湿既化热，熏蒸肺胃，其邪自胃达肺，由肺出表，
从汗而泄，则粒似细栗，色似水晶，故东南湿热之地，最多
白瘖，西北风燥之区，每盛斑疹。考古医书，只有斑疹，而
无白瘖，惟近世南医辈出，始得论及，然亦略而不备，殊不
知大江以南，地卑气湿，每至夏秋暑秽熏蒸之际，但觉身热
不已，面色晦滞，舌色腻浊，此即湿热之状，有诸内则形诸
外也，且湿乃重浊之邪，热为熏蒸之气，先伤气分，最易化
热，故胸腹必闷，脉大必缓，矧呕恶便溏，皆邪布三焦，气
化失清之症。故用半夏、茯苓流通中腕，加杏仁、蒌皮宜豁
土焦，通草、豆卷渗利下焦，合黄连、积实泄满，竹茹、陈
皮理气，俾三焦气机得宜，则湿热之邪，借以分消也。
疹瘰（一种皮肤出疹性疾病）表现为发热、恶寒，胸闷、腹痛，心烦燥热且想呕吐，这是邪气郁结在肺和胃。适宜使用杏仁、桔梗、枳壳、郁金、淡豆豉、黑山栀、薄荷、牛大力、苍耳子、连翘等药物，以发挥轻扬宣通肺气的作用。
疹属于肺经的风热，瘰属于胃中的湿热。所以疹的颗粒细小如蚊子叮咬的痕迹，出现在皮肤表面；瘰的颗粒较大如铜钱样，附着在肌肉层。这是因为肺主皮毛，胃主肌肉的缘故。病程初期必然出现胸膈满闷、腹中绞痛，这是由于风热壅塞阻滞，气机运行不畅，严重时会导致呕吐不止。然而，如果疹瘰伴随呕吐或腹泻，说明郁结阻滞的邪气得以疏泄，不必强行止住。因此使用杏仁、郁金、枳壳、桔梗来开通上焦，山栀、淡豆豉来祛除郁积之邪，薄荷、牛大力来祛风，连翘、苍耳子来化解热邪，这样邪气透出，瘰自然解除。
疹瘰有时隐没有时显现，瘙痒无度，这是风热在内蒸腾所致。适宜使用薄荷、牛大力、黄连、黄芩、荆芥、防风、蝉蜕、牡丹皮、连翘、黑山栀、杏仁、地肤子等药物，以清热祛风。
疹瘰既然已经显现，时而隐伏，全身瘙痒，大多是因为风热蕴结，气血不清澈。因此使用酒炒的黄芩、黄连，配合连翘、黑山栀来清火，薄荷、牛大力、防风、荆芥来祛风，蝉蜕、牡丹皮、杏仁、地肤子来清气血两分之热，这样热清则疹自消解。
白瘖（一种白色小疱疹）尚未出现时，表现为发热、身体疼痛，面色晦暗滞涩，舌苔粘腻，胸脘部不适，恶心呕吐，大便稀溏，脉象大而缓，这是热邪蕴结蒸腾所致。适宜使用黄连温胆汤加上杏仁、瓜蒌皮、通草、大豆卷等药物，以通利泄降三焦。
瘖病初发，必定是由湿热化生蒸腾，导致气分与湿浊分不清。因为湿气必然阻碍气机，热邪也会损伤正气。湿气既已化为热邪，熏蒸肺胃，其邪气从胃达肺，由肺出于体表，随汗液而泄出，所以颗粒像细小的粟米，颜色像水晶一样透明。因此东南湿热之地，最多见白瘖；西北风燥之区，每多盛行斑疹。查阅古代医书，只有斑疹的记载，而没有白瘖，只有近代南方医生辈出，才开始论述此病，但也简略而不完备。殊不知长江以南，地势低洼气候潮湿，每到夏秋暑秽之气熏蒸之际，只觉得身体发热不退，面色晦暗滞涩，舌色腻浊，这就是湿热的征象，内部有湿热则外部显现症状。而且湿气是重浊的邪气，热是熏蒸的气，先伤气分，最容易化热，所以胸部腹部必然闷胀，脉象必然迟缓。况且恶心呕吐、大便稀溏，都是邪气遍布三焦，气化功能失去清明的症状。因此使用半夏、茯苓流通中焦，加入杏仁、瓜蒌皮宣豁上焦，通草、大豆卷渗利下焦，配合黄连、枳实泻除痞满，竹茹、陈皮理气，使得三焦气机通畅适宜，那么湿热之邪，借此得以分别消除。
Zhenlu (a skin eruption disease) presents with fever, aversion to cold, chest tightness, abdominal pain, irritability and heat sensation with a desire to vomit. This indicates pathogenic factors stagnating in the Lung and Stomach. It is appropriate to use Xingren (Prunus armeniaca Seed), Jiegeng (Platycodon Root), Zhike (Aurantii Fructus), Yujin (Curcuma Longa Rhizome), Danshichi (Fermented Soybean), Heishanzhi (Gardeniae Fructus processed with charcoal), Bohe (Menthae Haplocalycis Herba), Nidali (Radix Acanthopanacis Senticosi), Can'erzi (Xanthii Fructus), Lianqiao (Forsythiae Fructus) and other herbs, to employ light and ascending actions to diffuse Lung Qi.
Zhen belongs to Wind-Heat of the Lung Meridian, while Luo (referring to the larger eruptions here) belongs to Damp-Heat in the Stomach. Therefore, Zhen particles are fine like mosquito bites and appear on the skin surface; Luo particles are large like coins and adhere to the muscle layer. This is because the Lung governs the skin and hair, and the Stomach governs the muscles. The onset must be preceded by chest and diaphragm fullness and colicky abdominal pain, caused by the obstruction of Qi mechanism due to congestion of Wind-Heat, leading to incessant vomiting in severe cases. However, if vomiting or diarrhea occurs alongside Zhenlu, it signifies that the stagnant pathogenic factors are being vented, and there is no need to stop them forcibly. Thus, Xingren, Yujin, Zhike, and Jiegeng are used to open the Upper Jiao; Shanzhi and Danshichi dispel stagnation; Bohe and Nidali expel Wind; Lianqiao and Can'erzi resolve Heat. Consequently, the pathogens are released, and the eruptions resolve spontaneously.
Zhenlu may appear intermittently or remain hidden, accompanied by unbearable itching, indicating internal steaming of Wind-Heat. It is appropriate to use Bohe, Nidali, Huanglian (Coptidis Rhizoma), Huangqin (Scutellariae Radix), Jingjie (Schizonepetae Spica), Fangfeng (Saposhnikoviae Radix), Chanyi (Bombyx Batryticatus), Danpi (Moutan Cortex), Lianqiao, Heishanzhi, Xingren, Difuzi (Kochiae Fructus) and other herbs, to clear Heat and expel Wind.
Once Zhenlu has appeared, sometimes hiding and sometimes showing, with generalized itching, it is largely due to the accumulation of Wind-Heat causing turbidity in Qi and Blood. Therefore, Jiuchao Qin (Scutellariae Radix fried with wine) and Jiuchao Lian (Coptidis Rhizoma fried with wine) are combined with Lianqiao and Heishanzhi to clear Fire; Bohe, Nidali, Fangfeng, and Jingjie expel Wind; Chanyi, Danpi, Xingren, and Difuzi clear both Qi and Blood levels. When Heat is cleared, the eruptions transform and disappear.
Before Baiyin (white miliary rash) appears, symptoms include fever, body pain, dull and sallow complexion, sticky tongue coating, chest and epigastric discomfort, nausea and vomiting, loose stools, and a large yet slow pulse. This indicates Heat accumulation and steaming. It is appropriate to use Huanglian Wendan Tang (Coptis Phlegm-Calming Decoction) added with Xingren, Loupi (Trichosanthis Pericarpium), Tongcao (Tetrapanacis Medulla), Doujuan (Sojae Semen Praeparatum) and other ingredients, to unblock and drain the Sanjiao.
The initial onset of Yin is invariably caused by the transformation of Damp-Heat into steaming, resulting in the indistinction between Qi and Dampness. Dampness inevitably obstructs Qi, and Heat damages Qi. Once Dampness transforms into Heat, it steams the Lung and Stomach. The pathogen moves from the Stomach to the Lung, emerges from the Lung to the exterior, and is excreted through sweat. Thus, the particles resemble fine millet grains and have a crystal-clear color. Therefore, Baiyin is most common in the humid and hot regions of the Southeast, whereas Maculae et Petechiae (spotted rashes) prevail in the dry and windy regions of the Northwest. Ancient medical texts record only Maculae et Petechiae but not Baiyin. Only with the emergence of Southern physicians in recent times has this condition been discussed, albeit briefly and incompletely. One should realize that south of the Yangtze River, the terrain is low and the climate damp. During summer and autumn, when暑秽 (summer heat and filth) steams, one feels persistent fever, dull complexion, and greasy tongue coating, which are signs of Damp-Heat. Internal pathology manifests externally. Moreover, Dampness is a heavy and turbid pathogen, and Heat is a steaming qi; they first injure the Qi level and easily transform into Heat. Hence, chest and abdominal stuffiness and a large, slow pulse are inevitable. Furthermore, nausea, vomiting, and loose stools are symptoms of pathogens pervading the Sanjiao and loss of clarity in Qi transformation. Therefore, Banxia (Pinelliae Rhizoma) and Fuling (Poria) are used to circulate the Middle Jiao; Xingren and Loupi are added to diffuse the Upper Jiao; Tongcao and Doujuan are used to leach out the Lower Jiao; Huanglian and Zhishi (Aurantii Fructus Immaturus) are combined to purge fullness; Zhuru (Bambusae Caulis in Taenia) and Chenpi (Citri Reticulatae Pericarpium) regulate Qi. This ensures the smooth flow of Qi mechanism in the Sanjiao, allowing the Damp-Heat pathogens to be dispersed and eliminated separately.
