斑疹初起，恶寒发热，头痛口渴，咳嗽嚏涕，目
赤脉数，此麻疹也。宜用薄荷、大力、荆芥、连翘、
杏仁、前胡、枇杷叶、赤柽柳等味，辛凉疏透也。
斑为阳明热毒，疹为太阴风热，总属温热所化，发泄于
外。其初起也，腠理不宜则恶寒;阳邪在表则头痛，热自内
蒸则口渴，邪干肺位则咳涕。当其未见点时，先宜疏透。故
用薄荷、荆芥、大力疏风泄汗，连翘、杏仁、前胡清宜气
分，枇杷叶、赤柽柳轻扬达表，冀其汗泄腠开，斑疹速透，
毌使传变为要。
斑疹汗泄，头不痛不恶寒，身热口渴，咽痛目
赤，斑疹隐隐，宜用薄荷、牛蒡、连翘，黑栀，杏
仁、射干、马勃、桔梗、甘草、元参等味，苦辛清解
也。
上条斑疹未见，而发热恶寒;此条斑疹既见，汗泄而头
不痛不恶寒，是腠理已开，外邪己泄。但口渴咽痛目赤，乃
里邪未解，热仍郁蒸，不可过散，宜以清解，故用薄荷、桔
梗、杏仁、牛蒡透泄，连翘、元参、黑栀清火，马勃、射
干、甘草宜上焦也。
斑疹烦热口渴，咽痛齿枯，舌黄尖绛，斑疹透
露。宜用白虎汤加连翘、元参、杏仁、射干，大青等
味，清气化斑也。
前条斑疹隐隐，尚宜疏泄，此条斑疹透露，而烦热口
渴，舌黄尖赤，乃邪渐传里，热不肯解，谅非疏泄透表所能
臻效。故宜白虎汤直清阳明气分，合连翘、元参化斑，杏
仁、射乾清上，大青解毒，庶免邪陷入营，神昏痉厥之虑
也。
斑疹初起时，出现恶寒、发热、头痛、口渴、咳嗽、打喷嚏流涕、眼睛发红、脉搏快速等症状，这是麻疹。适宜使用薄荷、牛蒡子、荆芥、连翘、杏仁、前胡、枇杷叶、赤柽柳等药物，采用辛凉的方法疏风透疹。
斑是阳明经的热毒，疹是太阴经的风热，总体都属于温热邪气所化生，发泄于体表。在疾病初期，如果腠理（皮肤毛孔及肌肉间隙）不通畅就会恶寒；阳邪在体表就会导致头痛；热气从体内蒸腾就会导致口渴；邪气侵犯肺脏部位就会导致咳嗽和流涕。当皮疹尚未显现时，应当先采用疏风透达的方法。因此使用薄荷、荆芥、牛蒡子来疏风发汗，连翘、杏仁、前胡来清宣气分，枇杷叶、赤柽柳轻扬以达表，希望借此使汗出腠理开泄，让斑疹迅速透出，防止病情传变是关键。
斑疹已经透出，头部不痛也不恶寒，身体发热、口渴、咽喉疼痛、眼睛发红，斑疹隐约可见，适宜使用薄荷、牛蒡子、连翘、黑栀子、杏仁、射干、马勃、桔梗、甘草、玄参等药物，采用苦辛清解的方法。
上一条所述为斑疹尚未显现，伴有发热恶寒；这一条所述为斑疹已经显现，出汗且头部不痛、不恶寒，说明腠理已经打开，外邪已经排出。但是仍有口渴、咽喉疼痛、眼睛发红，这是因为里邪未解，热气仍然郁结蒸腾，不可过度发散，应当以清解为主，因此使用薄荷、桔梗、杏仁、牛蒡子透泄，连翘、玄参、黑栀子清火，马勃、射干、甘草清利上焦。
斑疹伴有烦躁发热、口渴、咽喉疼痛、牙齿枯槁、舌苔黄、舌尖红绛，斑疹完全透出。适宜使用白虎汤加入连翘、玄参、杏仁、射干、大青叶等药物，采用清气化斑的方法。
前一条所述斑疹隐约可见，尚宜疏泄；这一条所述斑疹完全透出，伴有烦躁发热、口渴、舌苔黄、舌尖红赤，说明邪气逐渐传入体内，热气难以解除，推测单纯依靠疏泄透表的方法无法达到疗效。因此适宜用白虎汤直接清泻阳明经气分之热，配合连翘、玄参化解斑疹，杏仁、射干清利上焦，大青叶解毒，从而避免邪气陷入营分，导致神志昏迷、抽搐厥逆的忧虑。
At the initial stage of macules and papules (maculopapular eruptions), symptoms such as aversion to cold, fever, headache, thirst, cough, sneezing with nasal discharge, redness of the eyes, and a rapid pulse appear; this is measles. It is appropriate to use herbs such as Bohe (Menthae Haplocalycis Herba), Niubangzi (Arctii Fructus), Jingjie (Schizonepetae Spica), Lianqiao (Forsythiae Fructus), Xingren (Armeniacae Semen Amarum), Qianhu (Peucedani Radix), Pipaye (Eriobotryae Folium), and Chichengliu (Salicis Tomentosae Ramulus), employing acrid-cool methods to disperse wind and vent the eruption.
Macules (ban) are heat-toxins of the Yangming channel, while papules (zhen) are wind-heat of the Taiyin channel; both generally arise from transformation by warm-heat pathogens and manifest externally on the body surface. In the early stage, if the cou-li (skin pores and interstitial spaces) are not unobstructed, there will be aversion to cold; if yang pathogens are at the exterior, headache occurs; if heat steams from within, thirst arises; if pathogens interfere with the lung region, cough and nasal discharge result. When the spots have not yet appeared, it is first appropriate to use dispersing and venting methods. Therefore, Bohe, Jingjie, and Niubangzi are used to disperse wind and induce sweating; Lianqiao, Xingren, and Qianhu are used to clear and diffuse the qi level; Pipaye and Chichengliu are light and ascending to reach the exterior. The hope is that through sweating and opening of the cou-li, the macules and papules will emerge quickly, which is crucial to prevent the transmission and progression of the disease.
When macules and papules have emerged, accompanied by absence of headache and aversion to cold, but with fever, thirst, sore throat, red eyes, and faintly visible macules and papules, it is appropriate to use herbs such as Bohe, Niubangzi, Lianqiao, Hei Zhi Zi (Gardeniae Fructus), Xingren, Shegan (Belamcandae Rhizoma), Mabo (Catharanthi Herba), Jiegeng (Platycodonis Radix), Gancao (Glycyrrhizae Radix et Rhizoma), and Xuanshen (Scrophulariae Radix), employing bitter-acrid clearing and resolving methods.
In the previous paragraph, the macules and papules had not yet appeared, accompanied by fever and aversion to cold; in this paragraph, the macules and papules have already appeared, with sweating, no headache, and no aversion to cold, indicating that the cou-li have opened and external pathogens have been expelled. However, the presence of thirst, sore throat, and red eyes indicates that internal pathogens remain unresolved and heat is still stagnant and steaming. Over-dispersing should be avoided; instead, clearing and resolving is appropriate. Thus, Bohe, Jiegeng, Xingren, and Niubangzi are used for venting and expelling; Lianqiao, Xuanshen, and Hei Zhi Zi are used to clear fire; Mabo, Shegan, and Gancao are used to benefit the upper jiao.
When macules and papules are accompanied by vexatious heat, thirst, sore throat, withered teeth, yellow tongue coating, crimson tip of the tongue, and fully erupted macules and papules, it is appropriate to use Baihu Tang (White Tiger Decoction) added with Lianqiao, Xuanshen, Xingren, Shegan, and Da Qing Ye (Isatidis Folium), employing methods to clear qi-level heat and resolve macules.
In the previous paragraph, where macules and papules were faintly visible, dispersing and venting was still appropriate; in this paragraph, where macules and papules are fully erupted, accompanied by vexatious heat, thirst, yellow tongue coating, and crimson tip, it indicates that pathogens are gradually transmitting inward and heat is reluctant to resolve. It is presumed that merely using dispersing and venting methods to reach the exterior cannot achieve efficacy. Therefore, it is appropriate to use Baihu Tang directly to clear heat in the Yangming qi level, combined with Lianqiao and Xuanshen to resolve macules, Xingren and Shegan to clear the upper jiao, and Da Qing Ye to detoxify, thereby avoiding the risk of pathogens sinking into the ying level, leading to coma, convulsions, and syncope.
