热势炽盛导致口渴，大量饮水。此时解毒生津的功效无可比拟。但如果放纵饮水不知停止，水液就会蓄积在体内，引发各种灾异般的病变。
麻疹原本是由火邪引起的，心火在内亢盛，导致肺叶焦枯、胃中干枯，津液干涸。发热的时候，没有不感到口渴的。不可以给患者喝冷水，只适宜用绿豆、或者芝麻、或者炒过的陈米煎汤饮用。治疗方法应当以生津解毒为主，使用加味人参白虎汤，去掉方中的人参、甘草、糯米，加入连翘、牛蒡子、元参来主治。如果任由患者恣意饮用冷水，必然会导致水蓄的病证。如果水进入肺部，就会出现气喘、咳嗽的症状，适宜用葶苈子来泻除肺中的水湿；如果水进入脾脏，就会出现水肿、胀满、白色稀便的症状；水进入胃里，就会出现呕吐、呃逆的症状，适宜用猪苓、泽泻来泻除脾胃的水湿；如果水进入心脏，就会出现惊恐、心悸的症状，适宜用木通、赤茯苓来泻除心中的水湿；如果水进入肝脏，就会出现胁肋疼痛的症状，适宜用陈年芫花来泻除肝中的水湿；如果水进入肾脏与膀胱，就会出现小便不利，适宜用车前子、木通来泻除肾与膀胱的水湿。如果口渴且腹部胀满不能进食，这是本虚标实、气机阻滞的表现，属于败症，难以治疗。

麻疹消退后喜欢没有发热。如果遇到退热后又再次发热，说明毒邪尚未平息。治疗应当采用和解与清凉的方法，不要因为疹子已经收尽就轻视疏忽。
复热，是指热势已经消退后又重新发作的情况。这个症状起初是没有的，必须等到麻疹收没之后，热退身凉，过了六七天又重新发热。这个病症不是因为再次感受风邪所致，一定是因为余热没有清除干净，余毒复发所导致的。治疗适宜采用清凉和解的方法最为巧妙，可以使用柴胡麦门冬散，去掉方中的人参、甘草；或者使用生地骨皮汤，去掉甘草来主治。然而，麻疹初起时喜欢温热（指护理得当或用药温透），唯独忌讳麻疹痊愈之后又出现发热。为什么呢？大概是因为麻疹发热，多持续十一二天，少也不下七八天。热久则元气虚弱了。加上出疹之后，饮食不进，现在又再次高热，阴阳气血虚耗，不死还等待什么呢？急需调治，所以再次发热时，必须大补气血才可以。使用柴胡四物汤来主治。
朱氏说：已经康复却又出现发热，在病患家属中没有不引以为忧的。然而总不外乎这三种原因，治疗得法，必然不会有妨碍。

When the heat is severe, thirst arises, and the patient drinks copiously. At this time, no remedy can compare to those that clear toxicity and generate fluids. However, if drinking is indulged without restraint, water will accumulate in the middle jiao, giving rise to various pathological manifestations.
Measles is originally caused by fire pathogenic factors. Heart fire flares up internally, causing the lungs to become scorched and dry, the stomach to wither, and body fluids to be depleted. During fever, there is invariably thirst. Cold water should not be given for drinking; instead, it is appropriate to decoct mung beans, or sesame seeds, or fried aged rice in water for the patient to drink. The treatment method should focus on generating fluids and clearing toxicity. Use Jiawei Renshen Baihu Tang (Modified Ginseng and White Tiger Decoction), removing Renshen (Ginseng Root), Gancao (Licorice Root), and Nuomi (Glutinous Rice), and adding Lianqiao (Forsythia Fruit), Niubangzi (Arctium Fruit), and Yuanshen (Scrophularia Root) as the primary prescription. If one allows the patient to indulge in drinking cold water, it will inevitably lead to the disease of water accumulation. If water enters the Lung, it causes wheezing and coughing; Tingli (Descurainiae Semen) should be used to drain water from the Lung. If water enters the Spleen, it causes edema, distension, and white loose stools. If water enters the Stomach, it causes vomiting and hiccups; Zhuling (Polyporus) and Zexie (Alisma Rhizome) should be used to drain water from the Spleen and Stomach. If water enters the Heart, it causes fright and palpitations; Mutong (Akebia Caulis) and Chifuling (Red Poria) should be used to drain water from the Heart. If water enters the Liver, it causes hypochondriac pain; Chen Yuanhua (Old Genkwa Flower) should be used to drain water from the Liver. If water enters the Kidney and Bladder, it causes difficulty in urination; Cheqianzi (Plantago Seed) and Mutong (Akebia Caulis) should be used to drain water from the Kidney and Bladder. If the patient is thirsty but has abdominal distension and loss of appetite, this indicates deficiency in the root and excess/stagnation in the branch, constituting a critical condition that is difficult to treat.
Jiawei Renshen Baihu Tang (Modified Ginseng and White Tiger Decoction)
Renshen (Ginseng Root), Zhimu (Anemarrhenae Rhizoma), Shu Shigao (Prepared Gypsum Fibrosum), Gegen (Puerariae Lobatae Radix), Tianhuafen (Trichosanthis Radix), Maidong (Ophiopogonis Radix), Danzhuye (Lophatheri Herba), Gancao (Licorice Root), Nuomi (Glutinous Rice). Take a pinch of Nuomi as an adjuvant. Decoct in water until the rice is cooked.
After the measles rash subsides, it is favorable for the patient to have no fever. If recurrent fever occurs, it indicates that the toxin has not yet dissipated. Treatment should employ harmonizing and cooling methods. One must not neglect this simply because the rash has fully resolved.
Recurrent fever refers to the situation where fever has subsided but reappears. This symptom does not exist initially; it must wait until after the measles rash has receded, the fever breaks, and the body becomes cool. After six or seven days, the fever returns. This condition is not caused by a secondary contraction of wind pathogens, but rather by residual heat that has not been cleared and residual toxins returning. The treatment should ideally employ cooling and harmonizing methods. Use Chaihu Maimendong San (Bupleurum and Ophiopogon Powder), removing Renshen (Ginseng Root) and Gancao (Licorice Root); or use Shengdi Gupi Tang (Rehmannia and Dogwood Bark Decoction), removing Gancao (Licorice Root). However, during the initial stage of measles, warmth is preferred, whereas recurrence of fever after recovery is strictly contraindicated. Why? Because measles fever often lasts eleven or twelve days, and at least seven or eight days. Prolonged fever depletes primordial qi. Furthermore, after the eruption of the rash, food intake is poor. Now, with the return of high fever, yin and yang are severely exhausted. Death seems imminent. Urgent regulation and treatment are required. Therefore, for recurrent fever, it is necessary to greatly tonify qi and blood. Use Chaihu Siwu Tang (Bupleurum and Four Substances Decoction) as the primary prescription.
Zhu stated: Recurrent fever after recovery causes great worry for the patient's family. However, it generally stems from these three causes. With proper treatment, there will surely be no hindrance.
Chaihu Maimendong San (Bupleurum and Ophiopogon Powder) treats severe fever after the rash subsides.
Chaihu (Stir-fried with wine), Renshen (Ginseng Root), Yuanshen (Scrophularia Root) (each 5 fen), Longdancao (Gentian Root) (3 fen), Maidong (Ophiopogonis Radigo, heart removed) (8 fen), Gancao (Licorice Root). Decoct in water and take orally.

If the tongue coating is white, add Jingjie (Schizonepetae Herba) and Fangfeng (Saposhnikoviae Radix). If the tongue coating is yellow, add Lianqiao (Forsythia Fruit, stir-fried with wine). If constipation occurs, add Zhike (Aurantii Fructus) and Huomaren (Cannabis Semen). If constipation is severe, add Chouniu (Pharbitidis Semen).
