治疗原则：证候全部具备，消化功能恢复、大便通畅后，若疹子尚未发出，则不再强行促发；若疹子已经发出且稀疏，则不再让其增多。
方药组成：防风、羌活、麻黄根、升麻、生地黄、连翘（初出者减量，已出大者加量）、酒黄柏（各五分），当归身、黄连（各三分），川芎、藁本、柴胡、葛根、酒黄芩、生黄芩、苍术（各二分），细辛、生甘草、白术、陈皮、苏木、红花（各一分），吴茱萸（半分）。
煎服方法：将上述药物捣碎如麻豆大小，每次服用五钱，加水两大盏，煎至一盏，去渣滓，稍温热后空腹服用。
病机论述：疹子的发出，皆因内伤所致，必然要发出，这是营气逆乱的结果。严禁使用牵牛子、巴豆等攻下食药。适宜用半夏、枳术丸、大黄、益智仁之类药物，以去除泄泻，止住呕吐。如果耳尖发冷、呵欠、睡中惊悸喷嚏、眼涩，知道疹子必然要发出。各种大的脓疱、小水泡、疹瘾，这三种情况都是营气逆乱而寒气复郁于体表所致，适宜在四味升麻汤中加入当归身、连翘，这是固定的治法。
兼证加减：
如果肺脏成脓，先出现咳嗽气喘，或者气逆喘促，加入人参，少加黄芩，以泻伏火并补益元气。
如果心脏受邪发出小红疹，必须先见到咽干、惊悸、身热、肌肉肿胀、脉象弦洪，少加黄连。
如果命门受邪发出瘾疹，必须先见到骨痛、身热，疼痛不敢动摇，少加生地黄，又加黄柏。
总结：所有的疹子都属于阴证疮疡，都必须因为内伤饮食、脾胃不足、营气逆行所致，虽然火热在内炽盛，但阴寒覆盖于外，治疗方法如上所述。
辨别小儿疹证：
症状包括：呵欠、喷嚏、睡中发惊；或者耳廓发冷、眼涩；或者辨别是否夹食（积食）：口热、或者口中带有酸腐气味、奶瓣不消化；或者腹中疼痛。
治疗策略：
如果证候具备较少，疹子尚未发出，给予升麻汤三到五钱，带热服用。等待身体表面温和，疹子已经显现，再停止服药。
如果身体发凉，疹子未出，辨别确认为疹证，不问服用次数，直接等待身体表面温和及疮疹已经显现，然后才停止服药。只时时给予桔梗汤，以宽胸膈、利咽喉。
Translation:
Treatment Principle: When all symptoms are present and digestive function has recovered with normal bowel movements, if the rash has not yet erupted, do not forcibly induce eruption; if the rash has already erupted and is sparse, do not allow it to increase further.
Prescription Composition: Fangfeng (Saposhnikoviae Radix), Qianghuo (Notopterygii Rhizoma et Radix), Mahuanggen (Ephedrae Radix et Rhizoma), Shengma (Cimicifugae Rhizoma), Shengdihuang (Rehmanniae Radix), Lianqiao (Forsythiae Fructus) (reduce dosage for newly erupting ones, increase for fully erupted ones), Jiu Huangbai (Phellodendri Cortex prepared with wine) (each 5 fen), Dangguishen (Angelicae Sinensis Radix), Huanglian (Coptidis Rhizoma) (each 3 fen), Chuanxiong (Ligusticum Chuanxiong Rhizoma), Bencao (Ligustici Wallichii Rhizoma), Chaihu (Bupleuri Radix), Gegen (Puerariae Lobatae Radix), Jiu Huangqin (Scutellariae Radix prepared with wine), Sheng Huangqin (Scutellariae Radix raw), Cangzhu (Atractylodis Rhizoma) (each 2 fen), Xixin (Asari Radix et Rhizoma), Sheng Gancao (Glycyrrhizae Radix et Rhizoma raw), Baizhu (Atractylodis Macrocephalae Rhizoma), Chenpi (Citri Reticulatae Pericarpium), Sumu (Sappan Lignum), Honghua (Carthami Flos) (each 1 fen), Wuzhuyu (Evodiae Fructus) (0.5 fen).
Decoction and Administration: Crush the above herbs to the size of hemp seeds. Take 5 qian per dose, add two large zhen of water, decoct until one zhen remains, remove dregs, and take slightly warm on an empty stomach.
Pathogenesis Discussion: The eruption of rashes is always due to internal injury and must erupt; this is caused by the rebellion of Ying Qi (Nutritive Qi). It is strictly forbidden to use purgative foods or drugs such as Qianniuzi (Fructus Phytolaccae) and Badou (Crotonis Fructus). It is appropriate to use substances such as Banxia (Pinelliae Rhizoma), Zhizhu Wan (Bitter Orange and Atractylodes Macrocephala Pill), Dahuang (Rhei Radix et Rhizoma), and Yizhiren (Alpinia Oxyphylla Fructus) to treat diarrhea and stop vomiting. If the ear tips are cold, there are yawning, sneezing during sleep, startle, and dry eyes, it indicates that the rash will inevitably erupt. Various large pustules, small vesicles, and urticarial rashes are all caused by the rebellion of Ying Qi and the re-accumulation of cold in the exterior. It is appropriate to add Dangguishen and Lianqiao to Siwei Shengma Tang (Four-Ingredient Cimicifuga Decoction); this is a fixed method.
Modification for Complications:
If the Lung forms pus, characterized initially by cough and wheezing, or rapid breathing and panting, add Renshen (Ginseng Radix et Rhizoma) and a small amount of Huangqin (Scutellariae Radix) to drain latent fire and tonify Yuan Qi (Primary Qi).
If the Heart manifests as small red rashes, it must first present with dry throat, palpitations, fever, muscle swelling, and a wiry and surging pulse; add a small amount of Huanglian (Coptidis Rhizoma).
If the Mingmen (Gate of Life) manifests as urticarial rashes, it must first present with bone pain, fever, and pain preventing movement; add a small amount of Shengdihuang (Rehmanniae Radix) and also add Huangbai (Phellodendri Cortex).
Summary: All rashes belong to Yin-type sores and are invariably caused by internal injury from diet, insufficiency of the Spleen and Stomach, and rebellion of Ying Qi. Although fire-heat blazes internally, Yin-cold covers the exterior. The treatment method is as described above.
Differentiating Pediatric Rash Symptoms:
Symptoms include: yawning, sneezing, startle during sleep; or cold earlobes, dry eyes; or differentiating whether food stagnation is involved: hot mouth, sour breath odor, undigested milk curds; or abdominal pain.
Treatment Strategy:
If only few symptoms are present and the rash has not yet erupted, administer Shengma Tang (Cimicifuga Decoction) 3–5 qian, taken warm. Wait until the body surface feels mild and the rash becomes visible before stopping medication.
If the body is cool and the rash has not erupted, after confirming the diagnosis of rash, continue administration regardless of the number of doses, waiting only until the body surface feels mild and the sores/rash become visible before stopping. Only occasionally administer Jiegeng Tang (Platycodon Decoction) to widen the chest and diaphragm and benefit the throat.
