（斑毒附后）
疮疹之作，始自婴孩生时，啼声一出，则咽下口中秽浊，蓄之在胃，因气运变迁，主
客胜复邪气郁发，与元受秽浊激搏，而形于肌肉皮肤之外。初发有类伤寒，不拘四时，皆
有此候，经云∶春夏为顺，秋冬为逆，盖春夏则阳气布，玄府开，人之气血流畅，邪毒
易出，秋冬则寒气胜，而水冰地冻，人之气血凝泣（音涩），故难出也。小儿所患此证，轻重
不等，命名亦异。轻者如麻，俗言麻子，重者如豆，谓之豆疮，重而又重，密如浮漂，俗
曰赤漂。既传入此，已是危急。医与病家，切宜详审，故出各有其名，心为红点，肝为水
，肺为脓 ，脾主结痂。惟肾居下，不受秽浊，所以独无其证。若见疮色黑陷，乃毒
气入肾。急投麝香人齿散救之，及一匕金尤妙。此言五脏各有所主，及其发也。始焉壮
热腰痛咳嗽，面目皆赤，或乍凉乍热，两足微冷，有惊搐谵语者，有腹痛欲吐者，有头
痛烦渴者，六脉紧数，耳尻（音蒿）俱冷，呵欠顿闷，至五六日，身出红点，红点成水 ，水
成脓 ，脓 之后，结痂 则愈矣。此证才见，似是而非，若同而异，疑贰之间，但
以升麻汤加麻黄与之发表及清肺饮。盖肺主气，王氏曰∶豆疮气均则出快。故用之。仍
不可过投，兼此疾首尾无下法，若下之必损脾胃。然万物得土气温暖而生，下之则脾土
虚冷，气血无自而盛。故豆疮因脾胃虚冷，而气血亦衰，遂有伏陷之变。又《内经》云∶诸
痛痒疮疡，皆属于心。虽各藏形证不同，而心实为之主。心主血，因其血热在里，再遇
六淫侵袭，两相攻击，自内而形于外，则发之为豆疮，未有不先见其血点，而后结脓 。
故其原出于心，或痛或痒，以分虚实，经曰∶诸痛为实，诸痒为虚，切宜知此，不可妄投
药饵。若一出便齐者为重，不齐者为轻，以中和汤通顺表里，及 归汤催胀而已。既出
不多，发之亦少，此为本疏，不宜再发。有大热者，以导赤葛散利小府。微热者用 咀
五苓散，加人参、甘草，水煎。欲出不见者快斑饮，久而不结痂 者，是表有热，盛蒸
于皮肤，可用升麻汤加黄芩以解之。若豆疮见形，有渴泻吐痢，用陈氏木香散、异功散、
豆蔻丸治之。有虚痒者，多服 归汤及中和汤。以上豆疮，大约施治，不过如此，其余
杂证预防之法，胡大卿陈文秀二公之书，该载详备。或问升麻汤治豆疮已发未发皆可服，
何如。愚曰∶予每致思及此，屡见病家不循次序，不问可否，以为常服，自取危困，良
可叹也。殊不知古人立方，深有意焉。但后学不能究心造微，以为一定之方，误人多矣。
盖未发之先可服，使其解利肌肤，自然出快。已发之际便不可服，为其药性差凉，凝滞气
血，毒不能出，反以为害，结痂之后可服，使其解散余毒，气顺血和，免有豆痈之患。或
问豆疮倒靥，有用麝香、人齿散作效，亦有不效者何？予曰∶其说有二，若见黑陷，毒
气入肾，肾色主黑，盖齿者肾之余，用麝齿之法，引导归肾，而发出其毒，故效耳。及
用一匕金救之，其效尤速。若见痒塌灰白色，脾虚所致，多投陈氏异功散取效。以上二证，
各有主治，不可执一，切须详审。或问∶豆疮投紫草饮固好，亦有不服者。曾子曰∶处
方之妙，在乎君臣佐使，后之医者，不谙古法，令病家自取紫草，修合品味，或为汤使
入诸药内，彼欲速效，而倍用恣饮。按本草云∶紫草性寒，小儿脾气实者，或尔偶中，脾
气虚者，反以为害。如戴氏方名紫草茸饮，后人讹传此方，缺其茸字，盖茸者春月才生之
芽，色泽而红嫩，得阳气之使然。以类触类，所以用发豆疮故效，但罕得嫩茸，后以紫草
头仅半寸者代之，即与茸初萌处同类。今人
不达其理，遽全用之，有脾虚者服之作泻，疮陷不救者多。予尝目击其事，深为可伤。凡
治豆疮，不可不明此理。盖戴氏紫草茸饮，内有人参、黄 、当归、白芍药佐之，故用验
矣。或问∶病豆疮者，忌食粥然欤。予曰∶此俗忌也。病家恐患者疮烂如粥，故忌之。其
实不然。毒瓦斯自里达表，满口糜溃乳食不能进，非以粥饮饲之，则脾土虚而豆疮陷、必
致不救，深可痛惜。予尝调治此证，始终与粥，全活多矣。盖粥者以米为之，何毒之有，
为父母者，切宜知此。或问∶禁食荤腥者何？予曰∶此亦世俗拘执之论。天以五气生万物，
人以五味养五脏，豆疮之萌，始因藏受邪毒，感时气而郁发，自内达外．荣卫俱虚，里气
亦弱，必藉五味荤腥，以为滋补，使气顺血和，自然出快。但不可食动风发热之物，以
助毒瓦斯，亢则必害。或问∶豆疮后与产后相类何如？予曰∶盖产后之妇，血脉伤损荣卫
大虚，败血未尽，偶六淫侵袭，便致急证，亦有不救者，故郭氏着产后二十一论，正为此
设。且小儿豆疮，一身精血皆形于外，热作胀痛，叫声不已，耗损真气，结痂后表里俱
虚，荣卫亦弱，余毒未解，失于调护，暴感邪气，多致夭伤，与产后传变何异。在父母
者，倘不究心及此，悔将噬脐，为之晚矣。然有疮少气实，饮食如故，又不拘以此论，医
者宜审之，切勿例指为虚也。凡豆疮欲愈未愈之间，传变黑陷干枯，咳嗽失音，吐泻
烦渴，浑身手足俱冷，睡则昏迷，饮食减少，及痰多气促燥痒，皆为不治。医者宜察之。世
言麻子者，亦疹毒也。经曰∶疹属于脾，胃为脾之府，有疾则同矣。疹毒乃天行气运变
迁之使然，亦随天地乖戾之气而受病，故曰时气。不拘长幼，身发大热，咳嗽连声，腰
痛口干，足冷，有寒热腹痛者，有头疼自痢者，有烦热惊搐者，此热使然也。但外证形

（斑毒附后）
痘疹的发生，始于婴儿出生之时。啼哭一声出口，便咽下口中的秽浊之物，蓄积在胃中。因五运六气的变迁，主气与客气的胜复变化导致邪气郁结爆发，与先天受纳的秽浊相互激荡搏结，从而显现于肌肉皮肤之外。初发时症状类似伤寒，不分四季都有此候。医经说：春夏发病为顺证，秋冬发病为逆证。这是因为春夏阳气布散，汗孔（玄府）张开，人体气血流畅，邪毒容易透出；秋冬寒气盛，水结冰地冻，人体气血凝滞涩阻，所以难以透出。小儿患此病，轻重不等，命名也不同。轻的像麻疹，俗称麻子；重的像豆疮，称为豆疮；重而又重，密集如浮萍，俗叫赤漂。既然传入这种重症，已是危急之症。医生和家属务必详细审察。因此出疹各有其阶段名称：心对应红点，肝对应水泡，肺对应脓疱，脾主结痂。只有肾位居下焦，不受秽浊之气，所以独无其证。如果见到疮色黑陷，那是毒气入肾。急投麝香人齿散救治，以及使用一匕金效果更佳。这是说五脏各有所主及其发病表现。起初壮热、腰痛、咳嗽，面目皆红，或忽冷忽热，两脚微冷，有的出现惊厥抽搐、胡言乱语，有的腹痛想吐，有的头痛烦渴，六脉紧数，耳朵和尾骨（尻）都冷，打哈欠且突然感到闷乱。到了第五六天，身上发出红点，红点变成水泡，水泡变成脓疱，脓疱之后结痂就痊愈了。此证刚出现时，似是而非，若同而异，在疑似之间，只用升麻汤加麻黄给予发表，及清肺饮。因为肺主气，王氏说：豆疮气机均匀则透发迅速。所以用这些药。但仍不可过量投药，况且此病从头到尾没有攻下的治法，如果攻下必然损伤脾胃。然而万物得土气温暖而生，攻下则脾土虚冷，气血无法旺盛。所以豆疮因脾胃虚冷，而气血也衰弱，于是有伏陷的变化。又《内经》说：各种疼痛、瘙痒、疮疡，都属于心。虽然各脏腑形证不同，但心实际上是主宰。心主血，因为血热在体内，再遇六淫侵袭，内外相攻击，从内而形于外，就发为豆疮，没有不先见血点，而后结成脓疱的。所以其根源出于心，或痛或痒，以此区分虚实。经说：诸痛为实，诸痒为虚，务必知晓此理，不可妄投药物。如果一出疹就齐整的是重症，不齐整的是轻症，用中和汤通顺表里，及当归汤催胀而已。如果出疹不多，透发也少，这是正气疏泄，不宜再强行透发。有大热的，用导赤葛散利小便。微热的用咀五苓散，加人参、甘草，水煎服。欲出而未出的，用快斑饮。久而不结痂的，是表有热，盛热蒸腾于皮肤，可用升麻汤加黄芩以解之。如果豆疮见形，有口渴、腹泻、呕吐、痢疾，用陈氏木香散、异功散、豆蔻丸治疗。有虚痒的，多服当归汤及中和汤。以上豆疮的大致施治，不过如此，其余杂证预防的方法，胡大卿、陈文秀二公的书，记载详尽完备。有人问：升麻汤治豆疮已发未发皆可服，怎么样？我说：我每次深思此事，屡见病家不循次序，不问可否，以为常服，自取危困，实在可叹。殊不知古人立方，深有意蕴。只是后学不能潜心探究精微，把它当作一定之方，误人很多。大概未发之前可服，使其腠理开利，自然透发迅速。已发之际便不可服，因为其药性偏凉，凝滞气血，毒不能出，反而成为害处。结痂之后可服，使其解散余毒，气顺血和，避免豆痈之患。有人问：豆疮倒靥（指痘疮塌陷不起），有用麝香、人齿散奏效的，也有无效的，为什么？我说：道理有二种。如果见黑陷，毒气入肾，肾色主黑，牙齿是肾之余，用麝香、人齿之法，引导归肾，而发出其毒，所以有效。及使用一匕金救治，其效尤速。如果见痒塌灰白色，是脾虚所致，多投陈氏异功散取效。以上二证，各有主治，不可固执一端，务必详审。有人问：豆疮投紫草饮固然好，也有不服用的。曾子说：处方的妙处，在于君臣佐使的配合。后来的医者，不谙古法，让病家自己选取紫草，调配品味，或作为汤剂加入诸药内，他们想要速效，而加倍恣意饮用。按本草说：紫草性寒，小儿脾气实的，或许偶然中病，脾气虚的，反而成为害处。如戴氏方名紫草茸饮，后人讹传此方，缺了“茸”字。盖“茸”是春月才生的芽，色泽红嫩，得阳气之使然。以类触类，所以用发豆疮故有效，但难得嫩茸，后来用紫草头仅半寸者代替，即与茸初萌处同类。今人不达其理，遽全用之，有脾虚者服用之作泻，疮陷不救者多。我曾目击其事，深为伤感。凡治豆疮，不可不明此理。盖戴氏紫草茸饮，内有参、黄芪、当归、白芍药佐之，所以有效验。有人问：患豆疮者，忌食粥吗？我说：这是世俗的禁忌。病家恐患者疮烂如粥，故忌之。其实不然。毒瓦斯自里达表，满口糜烂溃破乳食不能进，非以粥饮饲之，则脾土虚而豆疮陷，必致不救，深可痛惜。我曾调治此证，始终给喝粥，保全活命的人很多。盖粥是用米做的，有什么毒呢？做父母的，务必知晓此理。有人问：禁食荤腥的原因是什么？我说：这也是世俗拘执之论。天以五气生万物，人以五味养五脏。豆疮之萌芽，始因脏腑受邪毒，感时气而郁发，自内达外，营卫俱虚，里气亦弱，必藉五味荤腥，以为滋补，使气顺血和，自然透发迅速。但不可食动风发热之物，以助毒瓦斯，亢盛则必有害。有人问：豆疮后与产后相类如何？我说：产后之妇，血脉伤损，营卫大虚，败血未尽，偶感六淫侵袭，便致急证，也有不救的，所以郭氏着产后二十一论，正是为此设。且小儿豆疮，一身精血皆形于外，热作胀痛，叫声不已，耗损真气，结痂后表里俱虚，营卫亦弱，余毒未解，失于调护，暴感邪气，多致夭折，与产后传变有何不同。做父母的，如果不究心于此，后悔将噬脐莫及，为之晚矣。然而有疮少、气实，饮食如故，又不拘泥于此论，医者宜审之，切勿一概指为虚证。凡豆疮欲愈未愈之间，传变黑陷干枯，咳嗽失音，吐泻烦渴，浑身手足俱冷，睡则昏迷，饮食减少，及痰多气促燥痒，皆为不治之症。医者宜察之。世人说的麻子，也是疹毒。经说：疹属于脾，胃为脾之府，有病则同。疹毒乃天行气运变迁之使然，亦随天地乖戾之气而受病，故曰时气。不拘长幼，身发大热，咳嗽连声，腰痛口干，足冷，有寒热腹痛者，有头疼自痢者，有烦热惊搐者，此热使然也。但外证形于身体头面，如蚊蚤所咬发红点而起头，其疮脚有紫黯色为异耳。盖因四时有非节之气，着人肌肤，留而不去，再经外邪郁蒸，与先天受蕴热相触，毒瓦斯遂发于外，形而为疹。如果热太甚，则为痈为疽，为赤紫丹瘤，传入脏腑，治之稍缓，亦致害人。有胎受秽液，热毒蕴蓄于肺胃，因感时气而发者，并以清肺饮疏表，及百解散去桂加黄连，水煎。或余毒之气上蒸，口齿糜烂作臭，饮食不便，以当归散加七宝散，入盐水姜煎服，并牛蒡汤疏风化毒。如果疹出盛时，头痛肚热，神思烦闷，麦门冬汤主之。如夏月得此证者，烦躁发渴，小便少，神不安，投却暑丹即效。有毒瓦斯甚者，满口成疮，目赤肿痛，失音恶心，此余毒在肺胃之间未解，致肺胃俱虚，肺虚则语声不全，胃虚则饮食不纳，急宜早治。如果气促心烦惊悸者，病必致危矣。世言此证有温毒发斑，有胃烂发斑。如果温毒发斑，其瘾疹如锦纹片，出于两腋之下。盖两腋者，气之道路，故蕴毒随气之道路而先出，其疾咳嗽烦闷，或呕清水，此因冬时感冒寒毒，停于肌肉之间，至春阳气发动，而形于外，名为温毒发斑。以百解散、牛蒡汤，及当归散加陈皮、黄连为治。胃烂发斑，初因伤寒下早，热毒乘虚入里，及当下而不下，亦致热毒内蒸于胃。胃受热毒，则发出于皮肤，斑之赤者可疗，黑者十死一生，治法亦同前议。活人书以玄参升麻汤、大青四物汤、化斑汤为治。大人小儿，病同一体，用药施治，无逾古法，但小方分剂则轻少不等耳。此证更宜投拔毒饮、升脉汤，前豆疮余毒发见，皮肤溃烂，治用黄土散。
(Afterword on Ban Du)
The onset of variola (smallpox) and exanthema (measles/rash) begins at the time of an infant's birth. Upon the first cry, the infant swallows the turbid substances in the mouth, which accumulate in the stomach. Due to changes in the Five Movements and Six Qi (Wu Yun Liu Qi), the interaction between the host and guest qi leads to the victory and reversal patterns, causing pathogenic factors to stagnate and erupt. These interact with the congenital turbid substances, creating a struggle that manifests externally on the muscles and skin. The initial presentation resembles Taiyang disease (a syndrome caused by pathogenic invasion of the Taiyang channel). This condition occurs regardless of the season. The classics state: "Spring and summer are favorable; autumn and winter are unfavorable." This is because in spring and summer, Yang Qi spreads, the pores (Xuan Fu) open, and human Qi and Blood flow smoothly, allowing pathogenic toxins to be expelled easily. In autumn and winter, Cold Qi prevails, water freezes, and ice covers the ground; human Qi and Blood become stagnant and sluggish, making expulsion difficult. Children suffering from this condition vary in severity and have different names. Mild cases resemble measles, commonly called "Ma Zi" (hemp seeds); severe cases resemble bean sores, called "Dou Chuang" (bean pox); extremely severe cases are dense like floating duckweed, colloquially known as "Chi Piao" (red float). Once it progresses to this stage, it becomes critical. Physicians and families must examine carefully. Thus, each stage has its specific name: the Heart corresponds to red spots, the Liver to blisters, the Lungs to pustules, and the Spleen to scabs. Only the Kidney, residing in the lower Jiao, does not receive turbid pathogens, so it uniquely lacks its own manifestation. If black sunken sores appear, it indicates toxin entering the Kidney. Immediately administer She Xiang Ren Chi San (Musk and Human Tooth Powder) for rescue, or use Yi Bi Jin (One Spoonful Gold) for superior efficacy. This describes the correspondence of the Five Zang Organs and their manifestations. Initially, there is high fever, lower back pain, coughing, reddening of the face and eyes, alternating chills and fever, slight coldness in both feet, convulsions with delirium, abdominal pain with nausea, headache with irritability and thirst, tight and rapid pulse in all six positions, cold ears and sacrum, yawning, and sudden oppression. By the fifth or sixth day, red spots appear on the body, turning into blisters, then pustules, and finally scabs, after which recovery occurs. When this condition first appears, it seems similar yet different. In cases of doubt, use Sheng Ma Tang (Cimicifuga Decoction) added with Mahuang (Ephedra) to release the exterior, along with Qing Fei Yin (Lung-Clearing Drink). Since the Lung governs Qi, Wang Shi stated: "When the Qi of Dou Chuang is balanced, eruption is rapid." Hence, these are used. However, they should not be overdosed. Moreover, this disease has no purgative method from start to finish; purging will inevitably damage the Spleen and Stomach. All things grow due to the warmth of Earth Qi; purging causes Spleen Earth to become deficient and cold, preventing Qi and Blood from flourishing. Therefore, due to Spleen-Stomach deficiency and cold, Qi and Blood decline, leading to sinking variations. Furthermore, the *Neijing* states: "All pain, itching, ulcers, and sores belong to the Heart." Although each organ has distinct forms and symptoms, the Heart is the master. The Heart governs Blood; when Blood Heat resides internally and encounters invasion by the Six Exogenous Pathogens, internal and external attacks cause the eruption of Dou Chuang externally, always preceded by blood spots forming pustules. Thus, the origin lies in the Heart. Pain indicates excess, while itching indicates deficiency, as stated in the classics: "All pain is excess; all itching is deficiency." One must understand this and avoid reckless medication. Uniform eruption indicates severe disease; irregular eruption indicates mild disease. Use Zhong He Tang (Harmonizing Decoction) to smooth the interior and exterior, and Dang Gui Tang (Angelica Decoction) to promote swelling. If few spots emerge and eruption is scant, it indicates sparse Zheng Qi, and forcing further eruption is inappropriate. For high fever, use Dao Chi Ge San (Zizyphus Root and Scutellaria Decoction) to promote urination. For mild fever, use Ju Wu Ling San (Five-Ingredient Powder with Poria) added with Renshen (Ginseng) and Gancao (Licorice), decocted in water. For lesions wanting to emerge but failing, use Kuai Ban Yin (Rapid Eruption Drink). For prolonged failure to scab, indicating exterior heat steaming the skin, use Sheng Ma Tang added with Huangqin (Scutellaria) to resolve it. If Dou Chuang takes shape accompanied by thirst, diarrhea, vomiting, or dysentery, treat with Chen Shi Mu Xiang San (Chen's Atractylodes Macrocephala Powder), Yi Gong San (Extraordinary Power Powder), or Dou Kou Wan (Cardamom Pill). For deficiency-related itching, frequently administer Dang Gui Tang and Zhong He Tang. The general treatment for Dou Chuang is as described above. For other miscellaneous conditions and prevention, refer to the detailed works of Hu Daqing and Chen Wenxiu. Someone asked: "Sheng Ma Tang can be taken before or after eruption of Dou Chuang; what do you think?" I replied: "I often ponder this. I have repeatedly seen families ignore order and suitability, taking it routinely, bringing themselves to danger. It is lamentable. They do not realize that ancient prescriptions have deep intent. Later scholars fail to investigate the subtleties, treating it as a fixed formula, misleading many. Before eruption, it can be taken to open the pores and facilitate rapid eruption. During eruption, it should not be taken because its cool nature stagnates Qi and Blood, trapping toxins and causing harm. After scabbing, it can be taken to resolve residual toxins, harmonize Qi and Blood, and prevent Dou Yong (bean abscess)." Someone asked: "Why does She Xiang Ren Chi San work for some cases of inverted scabs (Dao Ye) but fail in others?" I said: "There are two reasons. If black sunken sores appear, toxin enters the Kidney. The Kidney's color is black. Teeth are the surplus of the Kidney. Using Musk and Teeth guides the toxin to the Kidney and expels it, hence efficacy. Yi Bi Jin also works rapidly. If itching, collapsing, gray-white sores appear, it is due to Spleen deficiency; frequent administration of Chen Shi Yi Gong San yields results. These two syndromes have different treatments; do not adhere rigidly. Examine carefully." Someone asked: "Dou Chuang treated with Zi Cao Yin is good, but some refuse it." Zeng Zi said: "The妙 (wonder) of prescription lies in the roles of Sovereign, Minister, Assistant, and Envoy. Later physicians, unfamiliar with ancient methods, let families select Zi Cao (Arnebia/Lithospermum) themselves, mix flavors, or add it to decoctions. Desiring quick effects, they drink excessive amounts. According to Materia Medica: Zi Cao is cold. For children with solid Spleen Qi, it may occasionally work; for those with deficient Spleen Qi, it causes harm. Dai Shi's formula is named Zi Cao Rong Yin (Arnebia Sprout Drink). Later generations misprinted it, omitting 'Rong' (Sprout). 'Rong' refers to buds born in spring, red and tender, benefiting from Yang Qi. Like attracts like, so it promotes eruption effectively. But fresh sprouts are rare, so later people substituted half-inch tips of Zi Cao, similar to young sprouts. Modern people, lacking understanding, use the whole root indiscriminately. Those with Spleen deficiency suffer diarrhea, and many die from sunken sores. I witnessed this and am deeply saddened. One must understand this principle in treating Dou Chuang. Dai Shi's Zi Cao Rong Yin contains Renshen, Huangqi (Astragalus), Dang Gui, and Baishao (White Peony) as assistants, ensuring efficacy." Someone asked: "Is porridge forbidden for Dou Chuang patients?" I said: "This is a secular taboo. Families fear the sores rot like porridge, hence the prohibition. Actually, this is incorrect. Toxins move from interior to exterior. If the mouth is ulcerated and food cannot enter, feeding porridge prevents Spleen Earth deficiency and sunken sores, avoiding death. It is regrettable. I have treated such cases, consistently providing porridge, saving many lives. Porridge is made of rice; what poison does it contain? Parents must know this." Someone asked: "Why forbid meat and fish?" I said: "This is also a rigid secular view. Heaven generates all things with Five Qi; humans nourish Five Zang with Five Flavors. Dou Chuang originates from internal pathogenic toxins reacting with seasonal Qi, moving outward. Ying and Wei Qi are deficient, and Interior Qi is weak. One must rely on Five Flavors and meat/fish for nourishment to harmonize Qi and Blood and facilitate eruption. However, avoid wind-agitating and heat-producing foods that aid toxins; excess leads to harm." Someone asked: "How is post-Dou Chuang condition similar to postpartum?" I said: "Postpartum women suffer blood vessel damage, severe deficiency of Ying and Wei, and incomplete expulsion of lochia. Invasion by Six Exogenous Pathogens causes acute syndromes, sometimes fatal. Guo Shi wrote Twenty-One Discussions on Postpartum for this reason. Similarly, in children with Dou Chuang, essence and blood manifest externally. Heat causes pain and swelling, incessant crying consumes True Qi. After scabbing, interior and exterior are deficient, Ying and Wei are weak, residual toxins remain. Neglect in care leads to sudden pathogen invasion and early death, similar to postpartum complications. Parents who neglect this will regret too late. However, if sores are few and Qi is solid, with normal diet, this rule does not apply. Physicians should judge carefully and not label all as deficiency. Regarding Dou Chuang nearing cure, if it transforms into black, sunken, dry sores, cough, loss of voice, vomiting/diarrhea, irritability/thirst, cold limbs, coma during sleep, reduced appetite, excessive phlegm, shortness of breath, or dry itching, it is untreatable. Physicians must observe. What people call 'Ma Zi' is also Zhen Du (rash toxin). Classics state: 'Rashes belong to the Spleen; the Stomach is the Spleen's mansion.' Disease affects them similarly. Zhen Du results from epidemic Qi changes, influenced by adverse Heaven-Earth Qi, hence called 'Seasonal Qi'. Regardless of age, high fever, continuous cough, back pain, dry mouth, cold feet, chills/fever/abdominal pain, headache/dysentery, or irritability/convulsions occur due to heat. Externally, red raised spots appear on head/body like mosquito bites, with purple-dark bases. Non-seasonal Qi adheres to skin, lingering and combining with external pathogens and internal latent heat, causing toxins to erupt as rashes. If heat is extreme, it becomes carbuncle, gangrene, or erysipelas. Entering Zang-Fu, delayed treatment kills. Congenital turbid fluid with heat-toxin accumulating in Lungs/Stomem, triggered by seasonal Qi, is treated with Qing Fei Yin to release exterior, and Bai Jie San removing Gui Zhi (Cinnamon Twig) adding Huanglian (Coptis), decocted. If residual toxin steams upward causing oral/dental ulceration and bad odor, use Dang Gui San added with Qi Bao San, decocted with salt water and ginger, plus Niu Bang Tang (Burdock Decoction) to disperse wind and resolve toxin. During peak rash, with headache, abdominal heat, and mental agitation, Mai Men Dong Tang (Ophiopogon Decoction) is primary. In summer, with irritability, thirst, scant urine, and restlessness, Que Shu Dan (Heat-Expelling Pill) is effective. Severe toxin causing full-mouth sores, red/swollen/painful eyes, loss of voice, and nausea indicates unresolved residual toxin in Lungs/Stomach, causing deficiency. Lung deficiency leads to incomplete speech; Stomach deficiency leads to inability to eat. Early treatment is urgent. Shortness of breath, irritability, palpitations indicate critical condition. People speak of Wen Du Fa Ban (Warm Toxic Erythema) and Wei Lan Fa Ban (Stomach Rot Erythema). Wen Du Fa Ban presents as net-like rashes under armpits. Armpits are pathways of Qi; accumulated toxin follows Qi pathways and emerges first. Symptoms include cough, oppression, or vomiting clear fluid. Caused by Winter Cold Toxin stopping in muscles, emerging in Spring when Yang Qi moves. Treated with Bai Jie San, Niu Bang Tang, and Dang Gui San added with Chen Pi (Tangerine Peel) and Huanglian. Wei Lan Fa Ban starts from premature purging in Taiyang disease, allowing heat-toxin to enter interior, or failure to purge when needed, causing heat-toxin to steam in Stomach. Stomach heat-toxin erupts on skin. Red spots are treatable; black spots are nearly fatal. Treatment follows previous advice. *Huo Ren Shu* uses Xuan Shen Sheng Ma Tang (Scrophularia and Cimicifuga Decoction), Da Qing Si Wu Tang (Great Indigo Four Substances Decoction), and Hua Ban Tang (Spot-Resolving Decoction). Adults and children share the same pathology; treatment follows ancient methods, differing only in dosage for children. This condition also benefits from Ba Du Yin (Toxin-Pulling Drink) and Sheng Mai Tang (Pulse-Raising Decoction). For residual Dou Chuang toxin causing skin ulceration, treat with Huang Tu San (Yellow Earth Powder).
