麻疹是由胎毒引发，病位在心。肺与心相连，热毒随之侵袭。患者会出现咳嗽、鼻流清涕的症状，同时双眼泪水汪汪。
麻疹的证候特点是面部必然发红。伴有打哈欠、咳嗽、鼻流浓涕。眼泪汪汪，频繁打喷嚏。不要将其当作伤寒或其他杂证来治疗。
麻疹初起阶段，在皮疹尚未显现之前，必然出现身体发热、怕冷、头痛、咳嗽。或者呕吐，或者干呕，或者腹泻，或者腹痛，或者鼻塞，或者鼻流清涕。还有打喷嚏、打哈欠、眼睑浮肿、眼泪汪汪、腮部发红、身体疼痛、烦躁不安等症状。
所谓麻，是胎毒发作所致。所谓的“毒”，就是火邪。麻疹皮疹细小、颜色红碎且密集，行于皮肤之间，归属于手少阴心经，即君火。五脏中心与肺相连，肺位于上部。当心经火旺时，肺就会受累。因此，麻疹发作时，肺受到的毒害最重。之所以咳嗽，是因为心火炎上灼伤肺叶，导致肺叶焦枯。鼻流清涕，是因为鼻为肺之窍，火热灼烧肺金（肺属金），津液自流而出。眼中流泪，是因为肺热移传给肝，肝开窍于目。肝属木，木能生风，所以会有打哈欠的现象。呕吐和干呕，是心火流入胃中所致。肺与大肠相表里，肺热传至大肠，导致眼睑浮肿、腹痛并腹泻。腮部发红、烦躁，是心火旺盛的表现。打喷嚏，是肺经有火邪。如果患儿用手抓挠眉毛、眼睛、嘴唇、鼻子及面部，这是肺热的证候。
然而，麻疹虽然是胎毒，但没有不因为感受时气（流行性气候邪气）而发作的。所以其症状与伤寒相似，都有身热、怕冷、头痛、身体疼痛等表现。但是治疗麻疹的人，千万不要按照伤寒的方法来施治。应当首先以调理肺为主，总体原则宜泻火、清金（清肺热）。泻火应当使用黄连、黄柏、栀子仁、大青叶、玄参、连翘之类的药物。清金应当使用黄芩、知母、贝母、麦冬、石膏、天花粉、牛蒡子、地骨皮、桑白皮、杏仁之类的药物。
麻疹初起时，虽然与伤寒相似，但辨认麻疹必须仔细看两耳根下、颈项连接耳朵之间，以及背脊下方直到腰部的区域，必定会出现三五个红点，这就是麻疹发出的征兆（报标）。如果没有红点作为证据，就应当按照其他杂证进行治疗。这是经过多次验证有效的经验。如果确实有红点，并且现有的症状相符，那就是麻疹的征候。适宜使用宣毒发表汤，去掉升麻、桔梗、甘草，或者稍微加一点苏叶，或者稍微加一点胡荽，或者去掉淡竹叶来主治。或者使用葛根解肌汤，去掉赤芍、甘草，加入防风。或者再加苏叶、枳壳来主治。或者使用防风败毒散，去掉桔梗、甘草、石膏、知母，或者去掉淡竹叶，加入前胡、葛根来主治。以上方剂都以灯心草为药引服用，以疏风解肌，托毒外出，这样就可以安然无恙。即使有呕吐或腹泻，也不必拘泥顾虑。麻疹发出后，吐泻自然停止。因为麻疹属于热证，热气冲犯胃则呕吐，热气冲犯大肠则腹泻。这是麻疹的常见征候。麻疹发出，热势解除，吐泻的症状不治也会自止。不必担心吐泻不止而胡乱治疗。
朱氏说：辨认麻疹的方法只有二十七个字（注：原文称二十九字，实为二十七字口诀或泛指简法），在辨认麻疹时注意这些要点，就不会出错。
热气冲犯胃和大肠，出现呕吐和腹泻两个证候，这确实是经验之谈，而且不治自止。家有小儿者，了解这一点可以减轻一些忧虑。
宣毒发表汤：治疗麻疹发热、欲出而未出时的各种证候，都适宜使用。凡是地方上麻疹发作的时候，在初起阶段，如果不明确是否是麻疹证候，应当以此方为主治。纵然不是麻疹征候，即使是感受了伤寒邪气，使用此方也无妨碍。并在方后附加加减法。
薄荷叶（八分）、葛根、防风、荆芥穗、连翘、牛蒡子（炒）、木通、枳壳、淡竹叶（各一钱）、升麻、桔梗、甘草，以灯心草为引。（不要用生姜和姜皮）。冬天寒冷月份，可加苏叶（八分），再加葱白为引。暑天炎热月份，可加生黄芩一钱。总之，去掉升麻、甘草、桔梗不用。初起没有咳嗽的，适宜保留白陈皮以助咳出（注：此处原文逻辑似有误，通常无咳不加陈皮，或有咳去陈皮，依原文直译：宜用留白陈皮以甚其咳，意为通过陈皮促进肺气宣发，若有咳切勿再加，意指若已有咳则不需额外强调宣肺或避免燥烈，依原文语境理解为：若无咳，可用陈皮；若有咳，则不再加）。初起有往来潮热的，除去淡竹叶，以免解除肌肤之热，导致麻疹难以透发。在寒冷月份，仍适宜加苏叶、葱白以疏解表邪。初起潮热太严重的，加赤茯苓、生地黄，并可加生黄芩。不必拘泥于“麻疹初起用寒凉药会导致毒邪内伏、麻疹不得发出”的说法，正当使用这些药物，以保护肺脏免受火邪克制。但在春冬寒冷月份，黄芩等药的用量应略少。初起无汗的，加葱白以发汗，并稍微增加衣被覆盖，以取得汗出，使毒邪透发。切不可立即使用胡荽酒的方法，以免助长邪火内攻，使肺金再次受到严重克制。药中稍微加一点胡荽作为引子，稍可接受。初起不想吃东西的，不必治疗。因为热毒内蕴，自然不想进食。热毒一旦解除，自然就能进食。切勿添加进食开胃的药物。初起即见气喘急促的，加黄芩、葶苈子、瓜蒌仁，以清肺开胸。或者再加姜汁炒白芥子、紫苏子、莱菔子以降气。初起呕吐的，加竹茹、柿霜（如果没有柿霜，用柿饼也可以）。初起呃逆的，加枇杷叶、竹茹。初起鼻出血的，加鲜茅根。初起即出现咽喉痛的，加射干，加倍使用牛蒡子。初起即出现嘴唇干燥、牙齿燥热、舌苔枯黄、口渴等征候的，加麦冬、花粉、黄芩。严重的加黄连、黄柏、栀子仁等味，以预先化解。初起热势很盛，大便坚实的，加火麻仁二、三钱以润肠，用枳实以导滞，避免闭塞，导致热毒不能发散，进而变成紫黑色。如果大便不通，加生黑白丑末以利下。如果利下仍不通，必然产生气喘、鼻翼扇动、气逆等危重证候，此时即用黄连解毒汤加大黄、牛蒡子、连翘、地骨皮、桑白皮以通泄。如果兼有口渴的，并加麦冬、天花粉。初起大便溏稀的，方中的枳壳等量减少使用，以为开泄之路，这样可以避免便秘的祸患。初起溏泄且有微汗的，除去薄荷、竹叶，不可兼用止汗止泄的药物，以堵塞其发散的门路。初起泄泻的，除去枳壳。初起洞泄（水样便）的，除去枳壳，加猪苓、泽泻，以分利小便，不可止泄，以塞住其舒畅的机枢。初起小便赤红的，除去薄荷叶，加赤茯苓。或者再加车前子以利小便。初起小便不通的，合用导赤散（方剂见第二十六条），除去甘草，加车前子以通利。初起尿血的，如生地黄、黄连、黄柏、黄芩、栀子仁，都可以随意加入。再加牡丹皮以去除瘀血，避免留滞成为祸殃。冬季寒冷天气，无汗且不咳嗽的，酌情加蜜汁、和酒炒制的麻黄二、三分。其余各种证候，不能一一备述，应当根据所见到的证候，进行加减使用。至于药量的轻重，必须衡量患者的年龄大小。如果是月龄未满半岁的婴儿，只适宜用一杯的量给其服用，应当让乳母代为服用，使药性流入乳汁中，婴儿食用母乳，就如同服药一样。
葛根解肌汤：治疗麻疹初起，发热咳嗽，或者忽冷忽热，已经显现麻疹路径的情况，都适宜使用。初起未明确是否是麻疹证候，加减法同宣毒发表汤。并附上已现麻疹路径的加减法在方后。（总共去掉赤芍、甘草不用。）
葛根、前胡、荆芥穗、牛蒡子、连翘（去子）、蝉蜕（各八分）、木通（七分）、赤芍、甘草，灯心草为引。桑白皮（蜜蒸）、贝母（去心，姜汁蒸）。随意加入以下药物：已显现潮热特别严重的，加生地黄、地骨皮、赤茯苓。更可加黄芩。已显现口渴的，加麦冬、天花粉。已显现无咳嗽的，不妨稍微加一点留白陈皮。已显现无汗的，加葱白。已显现气喘的，加葶苈子、瓜蒌霜。气喘严重的，加白芥子、苏子、萝卜子（都用姜汁炒）。已显现呕吐的，加柿霜、竹茹。已显现鼻出血的，加茅根。出血严重的，再加黄芩、黄连（都生用）。已显现大便坚硬的，加枳实、火麻仁。已显现大便闭结的，加丑牛（牵牛子）。已显现大便闭结，用了丑牛仍不通的，加生大黄、黄连、黄芩。已显现大便溏稀的，加赤茯苓、泽泻。洞泄的，也照此办理。已显现小便赤涩的，加赤茯苓、泽泻。已显现小便闭塞不通的，加车前子，并加枳壳。
Measles originates from fetal toxin manifesting in the Heart. The Lungs are connected to the Heart, and heat-toxin invades them. Symptoms include coughing, clear nasal discharge, and eyes brimming with tears.
In measles cases, the face must be red. There is yawning, coughing, and thick nasal discharge. Tears flow freely, and sneezing occurs frequently. Do not treat it as Wind-Cold (Shanghan) or other distinct patterns.
During the initial stage of measles, before the rash appears, there will inevitably be fever, aversion to cold, headache, and coughing. There may also be vomiting, dry retching, diarrhea, abdominal pain, nasal congestion, or clear nasal discharge. Other symptoms include sneezing, yawning, swollen eyelids, watery eyes, reddened cheeks, body aches, and restlessness.
Measles is caused by the manifestation of fetal toxin. This "toxin" is essentially Fire. The measles rash is small, red, fragmented, and dense, moving within the skin, belonging to the Hand-Shaoyin Heart Meridian, which governs Ministerial Fire (Jun Huo). The Zang-Fu organs Heart and Lung are connected; the Lung resides superiorly. When Heart Fire flares up, the Lung is affected. Therefore, upon the onset of measles, the Lung suffers the heaviest toxicity. Coughing occurs because Heart Fire flares upward, scorching the Lung tissue. Clear nasal discharge happens because the nose is the orifice of the Lung; fire scorches Metal (Lung), causing fluids to flow out. Tears from the eyes occur because Lung heat transfers to the Liver, whose orifice is the eye. The Liver belongs to Wood, and Wood generates Wind, hence the yawning. Vomiting and dry retching result from Heart Fire flowing into the Stomach. The Lung and Large Intestine are exterior-interior pairs; Lung heat flows into the Large Intestine, causing swollen eyelids, abdominal pain, and diarrhea. Reddened cheeks and restlessness indicate strong Heart Fire. Sneezing indicates Fire pathogenic factors in the Lung Meridian. If the child scratches their eyebrows, eyes, lips, nose, and face, this is a sign of Lung heat.
However, although measles stems from fetal toxin, it invariably erupts after contracting seasonal qi (epidemic climate pathogens). Thus, its symptoms resemble Wind-Cold, including fever, aversion to cold, headache, and body pain. However, those treating measles must not apply Wind-Cold treatment protocols. One should first focus on the Lung, generally employing methods to purge Fire and clear Metal (clear Lung heat). To purge Fire, use herbs such as Huanglian (Coptis Rhizome), Huangbai (Phellodendron Bark), Zhiren (Gardenia Seed), Daqingye (Isatis Leaf), Xuanshen (Scrophularia Root), and Lianqiao (Forsythia Fruit). To clear Metal, use herbs such as Huangqin (Scutellaria Root), Zhimu (Anemarrhena Rhizome), Beimu (Fritillaria Bulb), Maidong (Ophiopogon Tuber), Shigao (Gypsum Fibrosum), Tianhuafen (Trichosanthes Root), Niubangzi (Arctii Fructus), Digupi (Lycium Cortex), Sangbaipi (Morus Root Bark), and Xingren (Prunus Seed).
Although the early stage of measles resembles Wind-Cold, identifying measles requires careful observation of the area below the roots of both ears, the neck connecting to the ears, and the lower back down to the waist. There must appear three to five red spots; these are the herald signs (Biao Biao) of measles. If no red spots are present as evidence, treat according to other distinct patterns. This has been repeatedly verified. If red spots are indeed present and match the aforementioned symptoms, it is a measles pattern. Use Xuan Du Fa Biao Tang (Toxin-Releasing and Exterior-Resolving Decoction), removing Shengma (Cimicifugae Rhizoma), Jiegeng (Platycodon Radix), and Gancao (Glycyrrhizae Radix et Rhizoma). Alternatively, add a small amount of Ziye (Perilla Folium) or Huyi (Coriandri Fructus), or remove Danzhuyeqian (Lophatheri Herba). Or use Gegen Jie Ji Tang (Puerariae Radix Muscle-Relieving Decoction), removing Chishao (Paeoniae Radix Rubra) and Gancao, adding Fangfeng (Saposhnikoviae Radix). Or add Ziye and Zhike (Aurantii Fructus). Or use Fangfeng Bai Du San (Saposhnikoviae Powder for Overcoming Toxicity), removing Jiegeng, Gancao, Shigao, and Zhimu, or removing Danzhuyeqian, adding Qianhu (Peucedani Radix) and Gegen (Puerariae Radix). All these formulas should be taken with Dengxincao (Junci Medulla) as a guiding herb to disperse Wind and relieve the muscle layer, pushing the toxin outward, ensuring peace and safety. Even if vomiting or diarrhea occurs, do not be constrained by them. Once the measles erupts, vomiting and diarrhea will cease naturally. Measles is a Heat pattern; Heat rushing to the Stomach causes vomiting, and Heat rushing to the Large Intestine causes diarrhea. This is a common presentation of measles. Once the measles erupts and heat resolves, vomiting and diarrhea stop without specific treatment. There is no need to worry about persistent vomiting/diarrhea and treat recklessly.
Zhu stated: The method for identifying measles consists of twenty-seven characters. Pay attention to these points when identifying measles, and errors will be avoided.
Heat rushing to the Stomach and Large Intestine causes vomiting and diarrhea. This is indeed empirical knowledge, and these conditions resolve spontaneously. Parents of young children can find relief from anxiety knowing this.
Xuan Du Fa Biao Tang (Toxin-Releasing and Exterior-Resolving Decoction): Treats various patterns during measles fever when the rash is wanting but not yet erupted. It is suitable whenever measles outbreaks occur locally, especially in the initial stage when it is unclear if the condition is measles. Use this formula as the primary treatment. Even if it is not measles but rather contracted Wind-Cold, using this formula is harmless. Additions and subtractions are listed at the end of the formula.
Boheye (Menthae Haplocalycis Herba) (8 fen), Gegen (Puerariae Radix), Fangfeng (Saposhnikoviae Radix), Jingjiesui (Schizonepetae Spica), Lianqiao (Forsythiae Fructus), Niubangzi (Arctii Fructus, stir-fried), Mutong (Akebiae Caulis), Zhike (Aurantii Fructus), Danzhuyeqian (Lophatheri Herba) (1 qian each), Shengma (Cimicifugae Rhizoma), Jiegeng (Platycodon Radix), Gancao (Glycyrrhizae Radix et Rhizoma). Use Dengxincao (Junci Medulla) as a guide. (Do not use Shengjiang [Zingiberis Rhizoma Recens] or Jiangpi [Zingiberis Pericarpium]). In cold winter months, add Ziye (Perillae Folium) (8 fen) and Congbai (Allii Fistulosi Bulbus) as a guide. In hot summer months, add Sheng Huangqin (Scutellariae Radix) 1 qian. Generally, remove Shengma, Gancao, and Jiegeng. If there is no cough in the initial stage, use Liubai Chenpi (Citri Reticulatae Pericarpium retained white pith) to promote coughing; if coughing is already present, do not add more. If there is alternating tidal fever in the initial stage, remove Danzhuyeqian to avoid resolving skin heat, which might hinder the eruption of measles. In cold months, still add Ziye and Congbai to disperse the exterior. If tidal fever is severe in the initial stage, add Chifuling (Poria with Red Host) and Shengdihuang (Rehmanniae Radix), and possibly Sheng Huangqin. Do not adhere to the theory that using cold/cool herbs initially traps the toxin and prevents eruption; they should be used to protect the Lung from being overcome by Fire. However, in spring and winter cold months, reduce the dosage of Huangqin etc. If there is no sweat in the initial stage, add Congbai to induce sweating, and slightly increase clothing/bedding to obtain sweat, allowing the toxin to penetrate. Do not immediately use Huyi wine methods, lest they assist evil fire to attack inward, severely overcoming Lung Metal. Adding a small amount of Huyi as a guide is acceptable. If there is loss of appetite in the initial stage, do not treat it; internal heat-toxin naturally suppresses appetite. Once heat-toxin resolves, appetite returns. Do not add digestive/appetite-stimulating drugs. If wheezing/dyspnea appears in the initial stage, add Huangqin, Tinglizi (Descurainiae Semen seu Lepidii Semen), and Gualouren (Trichosanthis Semen) to clear the Lung and open the chest. Or add Jiangzhi chao Baijiezi (Sinapis Semen), Jiazisu (Perillae Folium), and Laizizi (Raphani Semen) to descend Qi. If vomiting occurs in the initial stage, add Zhuru (Bambusae Caulis in Taenia) and Shishuang (Diospyri Fructus Frost); if Shishuang is unavailable, use Shibing (Diospyri Fructus). If hiccups occur, add Pipaye (Loquat Folium) and Zhuru. If epistaxis occurs, add Xian Maogen (Imperatae Rhizoma). If sore throat appears, add Yeyan (Belamcandae Rhizoma) and double the dose of Niubangzi. If dry lips, dry teeth, withered yellow tongue coating, and thirst appear, add Maidong, Hua Fen (Trichosanthis Radix), and Huangqin. Severe cases add Huanglian, Huangbai, and Zhiren to preemptively resolve. If heat is intense and stool is firm in the initial stage, add Huomaren (Cannabis Semen) 2-3 qian to moisten, and Zhishi (Aurantii Fructus Immaturus) to guide, preventing blockage where heat-toxin cannot vent, leading to purple-black discoloration. If stool is blocked, add Sheng Heibai Chouniu (Morning Glory Seed) powder to purge. If purgation fails, causing wheezing, nasal flaring, and counterflow Qi, use Huanglian Jiedu Tang (Coptis Decoction for Resolving Toxicity) plus Dahuang (Rhei Radix et Rhizoma), Niubangzi, Lianqiao, Digupi, and Sangbaipi to unblock. If accompanied by thirst, add Maidong and Tianhuafen. If stool is loose in the initial stage, reduce the dosage of Zhike etc. in the formula to allow drainage, avoiding constipation. If loose stool with slight sweating occurs, remove Boheye and Zhuye, and do not use antidiarrheal or antiperspirant agents, to avoid blocking the venting pathway. If diarrhea occurs, remove Zhike. If profuse watery diarrhea occurs, remove Zhike and add Zhuling (Poria) and Zexie (Alismatis Rhizoma) to separate clear and turbid via urination; do not stop diarrhea, to avoid obstructing the free flow mechanism. If urine is red in the initial stage, remove Boheye and add Chifuling. Or add Cheqianzi (Plantaginis Semen) to promote urination. If urinary retention occurs, combine Dao Chi San (Guide Out Redness Powder) (see Article 26), remove Gancao, and add Cheqianzi to unblock. If hematuria occurs, add Shengdihuang, Huanglian, Huangbai, Huangqin, and Zhiren as appropriate. Add Mudanpi (Moutan Cortex) to remove stagnant blood and prevent lingering harm. In winter cold weather, if there is no sweat and no cough, add Mijie (Honey-processed) and Jiuchao Mahuang (Ephedrae Herba stir-fried with wine) 2-3 fen. For other patterns not fully listed, adjust based on observed symptoms. Dosage strength must be weighed against the patient's size. For infants under half a year old, only a cupful should be given; have the nursing mother take it so the medicinal properties enter the milk, and the infant receives the medicine through breastfeeding.
Gegen Jie Ji Tang (Puerariae Radix Muscle-Relieving Decoction): Treats early measles with fever, coughing, or alternating chills and fever, when the measles pathway is already showing. Suitable for initial stages where measles diagnosis is unclear; additions/subtractions follow Xuan Du Fa Biao Tang. Additions for evident measles pathways are listed at the end. (Generally remove Chishao and Gancao.)
Gegen (Puerariae Radix), Qianhu (Peucedani Radix), Jingjiesui (Schizonepetae Spica), Niubangzi (Arctii Fructus), Lianqiao (Forsythiae Fructus, remove seeds), Chantui (Cicadae Periostracum) (8 fen each), Mutong (Akebiae Caulis) (7 fen), Chishao (Paeoniae Radix Rubra), Gancao (Glycyrrhizae Radix et Rhizoma), Dengxincao (Junci Medulla) as guide. Sangbaipi (Morus Root Bark, honey-steamed), Beimu (Fritillaria Bulb, remove heart, steam with ginger juice). Add subsequent herbs as needed: If tidal fever is severe, add Shengdihuang, Digupi, and Chifuling. Can further add Huangqin. If thirst is evident, add Maidong and Tianhuafen. If no cough is evident, add a little Liubai Chenpi. If no sweat is evident, add Congbai. If wheezing is evident, add Tinglizi and Gualou Shuang (Trichosanthis Fruit Pulp).
