经云∶赤紫丹瘤，皆心火内郁而发，赤如丹砂，故名丹毒。心主血而火性热，血热
相搏，阴滞于阳，即发丹毒。心虚寒则痒，心实热则痛，自腹生出四肢者易治，自四肢生
入腹者难疗。先用百解散表之，次以当归散加连翘、荆芥，水煎服，及牛蒡汤加炒麻仁，
研碎同煎与宣热拔毒。其次赤葛散，或初用化丹汤亦好。有身上发时，亦如前证，不甚
燥痒，但见出浮于遍体，神昏不悦，名阴湿毒证。先以冲和饮加南木香、水、姜煎服，次
用当归散、雄黄散。然此二证，不问赤白，若入腹入肾，多致为害，不可轻视如常，自取困尔。
凡患此证，是脾与心肝屡受极热，有所谓重舌、木舌，又谓之舌黄、鹅口，名虽异，
皆热也。大抵重舌生于舌下，挺露如舌，故曰重舌。然脾之络脉系舌旁，肝之络脉系舌
本，心之络脉系舌根。凡此三经，或为湿热风寒所中，则舌卷（音 ）缩，或舒长，或肿满，
宜消黄散、绿袍散主之，及当归散、羌活散与服。木舌者，舌肿硬而妨乳食，此为风热
盛也，以当归泻黄散、玉露饮，皆可服之次消黄散点擦舌上。盖舌者心之官，心热则生
疮破裂，肝壅则血出如涌，脾闭则白胎如雪，热则肿满，风则强木，口合不开，四肢壮热，
气喘语涩，即其候也。治法凉解上焦，及心肝脾三经邪热，疏风化痰，初用百解散加五和汤，水、姜、灯心煎投，次以
牛蒡汤，同当归散，入生地黄，水、姜煎服。鹅口者，始生婴儿，自一月之外，至半岁以上，忽口内
白屑满舌，则上 戴碍，状如鹅口，开而不合，语声不出，饮食多艰，亦因感受热毒，停
积于脾，故上 于舌，至极时药不能顿治，急以绢线札针嘴，约以粟谷长，刺破舌上下小
，如芥子大，见黄水清血微出即减，方投前证内药同服，及以朱砂膏、地黄膏，调化
涂点舌上，咽下无妨，或消黄散亦好。
医经中说：赤紫色的丹瘤，都是由于心火在内郁结而发作，颜色红得像丹砂一样，所以称为丹毒。心主司血液且火性属热，血与热相互搏结，阴气阻滞于阳气之中，就会引发丹毒。心气虚寒则表现为瘙痒，心气实热则表现为疼痛；从腹部生出并蔓延至四肢的容易治疗，从四肢生出并深入腹部的难以治愈。先用百解散来发散表邪，再用当归散加入连翘、荆芥，用水煎服，以及用牛蒡汤加入炒过的麻子仁，研碎后一同煎煮以宣散热毒。其次可用赤葛散，或者初起时服用化丹汤也很好。如果身上发出此证，也像前面的症状，但不怎么干燥瘙痒，只是看到皮疹浮泛遍布全身，神志昏沉不悦，这叫做阴湿毒证。先用冲和饮加入南木香、水、生姜煎服，接着用当归散、雄黄散。然而这两种证候，不论颜色是赤是白，如果病邪进入腹部或肾脏，大多会造成危害，不可像对待普通病症那样轻视，以免自取困顿。
凡是患这种证候，是因为脾、心、肝多次受到极热的侵袭，有所谓的重舌、木舌，又叫做舌黄、鹅口，名称虽然不同，但本质都是热邪所致。大体上，重舌生在舌头下面，挺出显露如同另一个舌头，所以叫重舌。然而脾的络脉联系在舌旁，肝的络脉联系在舌根底部，心的络脉联系在舌根。这三条经脉，如果被湿热风寒所中，就会导致舌头卷缩，或者舒张延长，或者肿胀满闷，适宜用消黄散、绿袍散主治，同时服用当归散、羌活散。木舌，是指舌头肿胀坚硬而影响吃奶进食，这是因为风热太盛造成的，可以服用当归泻黄散、玉露饮，之后也可以用消黄散点擦在舌头上。因为舌是心的官窍，心热则生疮破裂，肝气壅滞则出血如涌，脾气闭塞则舌苔白厚如雪，热邪则导致肿胀满闷，风邪则导致僵硬强直，嘴巴闭合不开，四肢壮热，气喘且言语涩滞，这就是它的征候。治疗方法是凉解上焦，以及清除心、肝、脾三经的邪热，疏风化痰，初起时用百解散加入五和汤，用水、生姜、灯心草煎服，接着用牛蒡汤，同当归散一起，加入生地黄，用水、生姜煎服。鹅口，多见于婴儿，从满月之外到半岁以上，忽然口腔内白色屑状物布满舌头，向上顶碍，形状像鹅嘴，张开而不能闭合，发不出声音，饮食非常困难，这也是因为感受了热毒，停滞积聚在脾脏，所以上泛于舌头，到了极点时药物不能立刻治愈，急忙用绢线扎住针尖，长度大约像粟谷那么大，刺破舌头上下小的溃疡处，像芥子大小，见到黄水和清血微微流出即见减轻，然后才投前面证候内的药物同服，以及用朱砂膏、地黄膏调匀涂点在舌头上，咽下去也无妨，或者用消黄散也可以。
The medical classics state: Red and purple dan liu (Dan tumors, a type of skin infection characterized by redness and swelling) are all caused by the internal stagnation of Heart Fire erupting. Their color is red like cinnabar, hence the name Dan Du (Erysipelas/Dan toxicity). The Heart governs Blood, and Fire nature is hot; when Blood and Heat contend with each other, Yin stagnates within Yang, resulting in the eruption of Dan Du. If the Heart is deficient and cold, itching occurs; if the Heart is excess and hot, pain occurs. Cases originating from the abdomen and spreading to the limbs are easy to treat, whereas those originating from the limbs and penetrating into the abdomen are difficult to cure. First, use Bai Jie San (Hundred-Element Powder to Release the Exterior) to release the exterior pathogen. Subsequently, administer Dang Gui San (Angelica Sinensis Powder) added with Lian Qiao (Forsythia Fruit) and Jing Jie (Schizonepeta Herb), decocted in water. Also, use Niu Bang Tang (Arctium Decoction) added with fried Ma Ren (Hemp Seed), crushed and decocted together to vent heat and extract toxicity. Alternatively, Chi Ge San (Red Kudzu Root Powder) may be used, or Hua Dan Tang (Transform-Dan Decoction) at the onset is also good. When this condition manifests on the body, it resembles the aforementioned symptoms but is not very dry or itchy; instead, floating rashes appear all over the body, accompanied by mental confusion and displeasure, known as Yin Shi Du Zheng (Yin-Damp Toxicity Syndrome). First, administer Chong He Yin (Harmonizing Infusion) added with Nan Mu Xiang (Aucklandia Root), water, and Sheng Jiang (Fresh Ginger), decocted and taken orally. Subsequently, use Dang Gui San and Xiong Huang San (Realgar Powder). However, for these two syndromes, regardless of whether the color is red or white, if the pathogen enters the abdomen or Kidney, it often causes harm. It must not be treated lightly as an ordinary condition, lest one bring upon oneself distress.
In general, suffering from this syndrome implies that the Spleen, Heart, and Liver have repeatedly suffered from extreme heat, leading to conditions such as Chong She (Double Tongue), Mu She (Wooden Tongue), also referred to as She Huang (Yellow Tongue) and E Kou (Goose Mouth). Although the names differ, they all stem from Heat. Generally, Chong She arises under the tongue, protruding like a second tongue, hence the name. The collateral vessels of the Spleen connect to the sides of the tongue, those of the Liver to the root of the tongue, and those of the Heart to the base of the tongue. If these three meridians are invaded by Damp-Heat, Wind, or Cold, the tongue may curl up, extend long, or become swollen and full. Xiao Huang San (Eliminate-Yellow Powder) and Lv Pao San (Green-Robe Powder) should be primarily used, along with Dang Gui San and Qiang Huo San (Notopterygium Powder). Mu She refers to a tongue that is swollen, hard, and interferes with suckling and eating, caused by excessive Wind-Heat. Dang Gui Xie Huang San (Angelica Draining-Yellow Powder) and Yu Lu Yin (Jade-Dew Infusion) can be taken, followed by applying Xiao Huang San to rub on the tongue. Since the tongue is the organ of the Heart, Heart Heat generates sores and rupture; Liver congestion causes bleeding like a gush; Spleen closure results in white coating like snow; Heat causes swelling and fullness; Wind causes stiffness and inability to open the mouth. Accompanying signs include high fever in the four limbs, panting, and slurred speech. The treatment method involves cooling and resolving the Upper Jiao (Upper Burner), clearing pathogenic heat from the Heart, Liver, and Spleen meridians, dispersing Wind, and transforming Phlegm. Initially, use Bai Jie San added with Wu He Tang (Five-Harmonies Decoction), decocted with water, ginger, and Deng Xin Cao (Rush Pith). Subsequently, use Niu Bang Tang combined with Dang Gui San and Sheng Di Huang (Rehmannia Root), decocted with water and ginger. E Kou typically affects infants from one month to over half a year old. Suddenly, white debris fills the tongue inside the mouth, obstructing upwards, resembling a goose's mouth, remaining open and unable to close, with no voice and difficulty in feeding. This is also due to contracting Heat-Toxin, which stagnates and accumulates in the Spleen, then floats up to the tongue. At the peak stage, medication alone cannot instantly cure it. Urgently, tie a needle tip with silk thread, approximately the length of a millet grain, and pierce the small ulcers on the upper and lower parts of the tongue, sized like a mustard seed. Once yellow fluid and clear blood emerge slightly, relief will occur, after which the medications for the aforementioned syndromes can be administered. Additionally, apply Zhu Sha Gao (Cinnabar Ointment) and Di Huang Gao (Rehmannia Ointment) mixed and dabbed on the tongue; swallowing them is harmless. Xiao Huang San is also suitable.
