凡出疹之先，或有胃火，及出疹之后，余毒不散，此热毒收于牙龈上下，故并唇口生疮，遇有此证，
每日用温米泔水洗十余次，（或用生甘草汤漱口）急用解毒之药治之，若或失治多变走马疳也。
凡疹初热一日至五六日之间，多有腹痛之证，此大肠之火郁于脾窍之中，故作腹痛。
俱不可认作伤食，用消导之药，或以手揉，俱
能致害。但解疹毒，毒散则腹痛自止，最宜慎之。
凡疹后余毒未尽，随当解之。若停留日久不解，则必致喘嗽，或喉中痰响，或为四支冷痹，或目无光彩面
色青白，或鼻孔如烟筒，或嗽声不出，若右手一指脉轻取散乱，重按全无，则成难治之证矣。
疹子收后身有微热者，此虚热也，不须治之，待血气和畅，其热自退。若热势太甚，或日
久不减，宜用柴胡麦门冬散，甚则黄连解毒汤或合人参白虎汤。
疹后热不退而发枯毛竖，肉消骨立，渐渐羸瘦，为骨蒸劳瘵之证者，宜万氏柴胡四物汤主之，或芦
荟肥儿丸加当归连翘治之。迟则变证为睡则露睛，口鼻气冷，手足厥逆，遂成慢脾风，螈 不治之证矣。
疹后热不除，忽作搐者，不可以急惊风同论，宜导赤散加人参麦门冬送七味安神丸。小
便清者可治，短少者难治。如见多痰或用抱龙丸，或以四物汤加麦门冬枣仁淡竹叶甘草龙
胆草黄连茯苓辰砂石菖蒲之类治之，或以此药为末用，蒸饼，猪心血为丸服亦可。
疹退后多有咳嗽之证，若微嗽不已者，此余毒未尽也，用清肺饮加生甘草牛蒡子主之。
若嗽甚气逆发而不已者，此肺中伏火，金虚叶焦也，宜清肺饮或清肺汤合人参白虎汤六一
散之类主之。若身热顿嗽，甚至饮食俱呛出，或咳出血，皆热毒乘肺而然，宜多用门冬清肺
汤或加连翘或清金降火汤主之。若咳甚而面浮目肿，胸高喘急，血退场门鼻，面色青赤，昏躁
摇头者，死证也。又有肺气本虚，为毒所逼而发喘不已，但无嗽血呛食等证者，宜用清肺饮
倍加人参治之。不可拘于肺热之说，而纯用清肺解毒之药也。
疹后余热未尽，或热甚而失血者，四物汤加茵陈木通以利小便，热气下行则愈，若血在上者去川芎。
疹后余毒入胃，久而不散，以致牙龈黑烂，肉腐血出，臭气冲人者名为走马疳，用马
鸣散主之。甚者急用人中白芦荟使君子龙胆草黄连五灵脂浸蒸饼为丸，滚水服之，以清胃
火。若面颊浮肿，环口青黑，齿脱唇崩，鼻坏者，死证也。疹退之后，饮食如常，动止如故，
乃卒然心腹绞痛，遍身汗出如雨者，此因元气虚弱，失于调养，外虽无病，内实亏损，偶然为
恶气所中，谓之中恶，此朝发夕死之证。
凡是出疹子之前，如果有胃火，或者在出疹子之后，余留的热毒没有消散，这些热毒收敛积聚在牙龈上下，导致嘴唇和口腔生疮。遇到这种情况，每天用温热的米泔水清洗十余次（或者用生甘草汤漱口），并立即使用解毒的药物进行治疗，如果延误治疗很容易转变为走马疳（一种严重的口腔坏死性疾病）。
凡是疹子初起发热一天到五六天之间，多有腹痛的症状，这是因为大肠的火气郁结在脾窍之中，所以引起腹痛。都不可以误认为是伤食（饮食积滞），使用消导（帮助消化）的药物，或者用手揉按腹部，都会造成危害。只要解除疹毒，毒气消散了腹痛自然停止，这一点最需谨慎注意。
凡是疹子消退后余毒未尽，应当随即予以清除。如果停留日久不消除，就一定会导致气喘咳嗽，或者喉咙中有痰鸣声，或者四肢寒冷麻木，或者眼睛无光彩、面色青白，或者鼻孔像烟筒一样张开，或者咳嗽声音发不出，如果右手寸关尺三部脉中，轻取时散乱，重按时完全摸不到，这就成了难以治疗的证候。
疹子收没之后身体有轻微发热的，这是虚热，不需要治疗，等待气血调和通畅，热度自然会退去。如果热势非常严重，或者日久不退，适宜使用柴胡麦门冬散，严重时可用黄连解毒汤或合用人参白虎汤。
疹后热度不退且头发干枯竖起，肌肉消瘦、骨骼显露，逐渐变得瘦弱，属于骨蒸劳瘵（类似结核病的一种慢性消耗性疾病）的证候，适宜用万氏柴胡四物汤为主治疗，或者用芦荟肥儿丸加当归、连翘治疗。如果拖延不治，病情变化为睡觉时眼睛半睁露睛，口鼻气息冰冷，手足厥冷逆乱，最终形成慢脾风（小儿慢惊风的一种），抽搐不止，属于不治之症。
疹后热度未除，突然发生抽搐的，不可以与急惊风同样看待，适宜用导赤散加人参、麦门冬送服七味安神丸。小便清长的是可治之症，小便短少难治的。如果见到痰多，或者使用抱龙丸，或者用四物汤加麦门冬、枣仁、淡竹叶、甘草、龙胆草、黄连、茯苓、辰砂、石菖蒲等药物来治疗，或者将这些药研成粉末，用蒸饼和猪心血做成丸剂服用也可以。
疹子退去后多有咳嗽的症状，如果是轻微咳嗽不止的，这是余毒未尽，用清肺饮加生甘草、牛蒡子为主治疗。如果是咳嗽剧烈、气逆发作不止的，这是肺中潜伏的火气，肺气虚弱如金叶焦枯，适宜用清肺饮或清肺汤合用人参白虎汤、六一散等为主治疗。如果是身体发热突然咳嗽，甚至饮食都呛咳出来，或者咳出血，都是热毒侵袭肺部所致，适宜多用门冬清肺汤或加连翘，或用清金降火汤为主治疗。如果咳嗽剧烈且面部浮肿、眼睛肿胀，胸部高耸、喘息急促，大便带血、鼻孔流血，面色青赤，昏沉烦躁、摇头晃脑的，是死证。又有肺气本来虚弱，被毒邪逼迫而不断喘息的，只要没有咳血、呛食等症状，适宜用清肺饮加倍加入人参来治疗。不可拘泥于肺热的说法，而单纯使用清肺解毒的药物。
疹后余热未尽，或者热势严重导致失血的，用四物汤加茵陈、木通以利小便，热气下行则痊愈，如果出血部位在上部的，去掉川芎。
疹后余毒进入胃部，长久不散，导致牙龈黑烂，肌肉腐烂出血，臭气冲人的，名为走马疳，用马鸣散为主治疗。严重的紧急用人中白、芦荟、使君子、龙胆草、黄连、五灵脂浸泡后蒸饼为丸，滚水送服，以清胃火。如果面颊浮肿，口周青黑，牙齿脱落、嘴唇崩坏，鼻子坏死的，是死证。疹子退去之后，饮食如常，行动举止如故，却突然心腹绞痛，全身出汗如雨下的，这是因为元气虚弱，失去调养，外表虽然无病，内部实则亏损，偶然被恶气所中，称为中恶，这是早晨发病晚上死亡的证候。
Before the eruption of measles (Rash), there may be Stomach Fire, or after the eruption, residual toxic heat fails to dissipate. This heat-toxin gathers in the upper and lower gums, causing sores on the lips and mouth. In such cases, wash with warm rice-washing water more than ten times daily (or rinse with Raw Licorice Decoction), and urgently administer detoxifying herbs. If treatment is delayed, it may transform into "Zou Ma Gan" (Gangrenous Stomatitis).
Between one to five or six days after the initial fever of the rash, abdominal pain is common. This is due to Large Intestine Fire stagnating within the Spleen's orifice, causing abdominal pain. Do not mistake this for Food Stagnation; using digestive-promoting herbs or rubbing the abdomen can cause harm. Only by resolving the rash toxin will the abdominal pain cease upon its dissipation; utmost caution is required.
If residual toxins remain after the rash subsides, they should be cleared immediately. If left unresolved for a long time, it will inevitably lead to wheezing and coughing, phlegm rattling in the throat, coldness and numbness in the four limbs, lusterless eyes with a cyan-white complexion, nostrils flaring like bellows, or inability to produce a cough sound. If the pulse at the right hand is scattered when lightly palpated and completely imperceptible when heavily pressed, it becomes a difficult-to-treat condition.
After the rash recedes, if there is slight body heat, this is Deficiency Heat, which requires no treatment; once Qi and Blood flow smoothly, the heat will subside spontaneously. If the heat is severe or persists for a long time, Chai Hu Mai Men Dong San (Bupleurum and Ophiopogon Powder) is suitable; in severe cases, Huang Lian Jie Du Tang (Coptis Decoction for Relieving Toxicity) or Ren Shen Bai Hu Tang (Ginseng White Tiger Decoction) may be used.
If heat persists after the rash, accompanied by dry, upright hair, emaciation, and skeletal prominence, leading to gradual wasting, it constitutes Gu Zheng Lao Zhai (Bone-steaming Consumption Disease). Wan Shi Chai Hu Si Wu Tang (Wan’s Bupleurum Four Substances Decoction) is indicated, or Lu Hui Fei Er Wan (Aloe Fattening Infant Pill) added with Dang Gui and Lian Qiao. Delayed treatment may lead to symptoms such as eyes half-open during sleep, cold breath from mouth and nose, and cold extremities, eventually forming Man Pi Feng (Slow Spleen Wind/Chronic Pediatric Convulsion), a convulsive condition that is incurable.
If heat remains after the rash and sudden convulsions occur, this should not be treated as Ji Jing Feng (Acute Convulsive Wind). Instead, use Dao Chi San (Guide Out Red Powder) added with Ren Shen and Mai Men Dong to deliver Qi Wei An Shen Wan (Seven-Ingredient Calming Spirit Pill). Clear urine indicates treatability; scanty urine indicates difficulty. If excessive phlegm is present, Bao Long Wan (Embracing Dragon Pill) may be used, or Si Wu Tang (Four Substances Decoction) added with Mai Men Dong, Suan Zao Ren, Dan Zhu Ye, Gan Cao, Long Dan Cao, Huang Lian, Fu Ling, Chen Sha, and Shi Chang Pu. These can also be powdered and formed into pills with steamed dough and pig heart blood for administration.
After the rash fades, coughing is common. Persistent mild coughing indicates residual toxins; clear Lung Drink (Qing Fei Yin) added with Raw Gan Cao and Niu Bang Zi is primary. Severe coughing with rebellious Qi and continuous onset indicates latent fire in the Lung and deficiency of Metal causing leaf-like scorching; Qing Fei Yin or Qing Fei Tang combined with Ren Shen Bai Hu Tang and Liu Yi San is appropriate. Sudden coughing with body heat, even causing food and drink to be regurgitated, or hemoptysis, results from heat-toxin attacking the Lung; Men Dong Qing Fei Tang (Ophiopogon Clearing Lung Decoction) with added Lian Qiao, or Qing Jin Jiang Huo Tang (Clear Metal Descending Fire Decoction) should be used extensively. Severe coughing with facial edema, swollen eyes, distended chest, rapid breathing, hematochezia, epistaxis, cyan-red complexion, coma, irritability, and head shaking constitutes a death sign. Additionally, if inherent Lung Qi deficiency is forced by toxins to cause persistent wheezing, without hemoptysis or choking on food, Qing Fei Yin with doubled Ren Shen is suitable. One must not rigidly adhere to the theory of Lung Heat and solely use clearing-Lung and detoxifying herbs.
If residual heat remains after the rash, or severe heat causes bleeding, Si Wu Tang added with Yin Chen and Mu Tong promotes urination; as heat qi descends, recovery occurs. For bleeding located superiorly, remove Chuan Xiong.
If residual toxins enter the Stomach and fail to dissipate over time, causing black rotting gums,腐 flesh, bleeding, and foul odor, it is named Zou Ma Gan. Ma Ming San (Horse Cry Powder) is primary. In severe cases, urgently use Ren Zhong Bai, Lu Hui, Shi Jun Zi, Long Dan Cao, Huang Lian, and Wu Ling Zhi, soaked and formed into pills with steamed dough, taken with boiling water to clear Stomach Fire. Cheek swelling, cyan-black color around the mouth, tooth loss, lip collapse, and nasal destruction constitute death signs. After the rash recedes, if diet and movement are normal, but sudden cardiac and abdominal colic occur with profuse sweating like rain, this is due to deficient Yuan Qi and lack of care. Although externally asymptomatic, internally there is substantial depletion, caused accidentally by malignant Qi invasion, termed Zhong E (Sudden Evil Invasion), a condition where morning onset leads to evening death.
