疹症属于阳毒，感染后病情暴烈凶险，危害极大，且变化迅速。因此在发热期间，最适宜采用解表散邪的方法，务必使疹点透发彻底，这样才能避免余毒蕴结化热的隐患。如果表证发散不透，或因风寒阻塞、饮食不当、触犯禁忌等原因，即使疹点已消退，也常出现多种残留症状。疹后体温理应恢复正常，若仍有余热未清，需根据具体证候仔细辨证。如出现呕吐，仍使用前面的方剂；若便秘，则加入制大黄。如果出现胸部高耸如圭状、耸肩喘息、口鼻出血、面色红赤或青黑枯暗，这些都是不良的征兆。然而也有因肺气虚弱，被余毒郁遏而引发气喘，连续不断的情况，可参考使用止嗽清肺方。如果日夜烦躁不安，胡言乱语甚至狂乱，主方选用调六一散（方见暑门章节），用辰砂灯心汤送服。若小便短赤，可用五苓散（方见便癃章节）加黄芩、黄连煎煮，调入辰砂服用。
对于烦躁谵语，可服用升麻葛根汤、辰砂六一散。根据所见证候，酌情使用以下方剂。
止嗽清肺方：知母、贝母、天门冬、麦冬、桔梗、软石膏、杏仁、马兜铃（各等分），糯米一百粒，水煎服。热象重者加连翘。
气热鼻干、毛发焦枯咳嗽：麦门冬、桔梗（各二钱），知母（一钱），荆芥穗（一钱），天粉石菖蒲（一寸，以九节者为佳），诃子肉（各四分），水煎服。
热邪乘袭肺金，声音嘶哑咳嗽气喘：当归（酒洗）、白芍（酒炒）、生地黄（酒洗）、陈皮、贝母、瓜蒌仁、白茯苓、片黄芩（酒炒）、栀子（炒）、天门冬、玄参、麦门冬、桑白皮、杏仁。热重者加黄连、石膏、苏梗、甘草。水煎服。
咳嗽不止：陈皮、半夏、茯苓、黄连（姜炒）、甘草、竹茹，水煎服。
腹泻不止：猪苓、泽泻、滑石、赤芍、黄连（姜炒）、升麻、甘草，水煎服。若不止，加止泻药。
痢疾不止：黄芩、芍药（各一钱半）、黄连、枳壳、当归、木通、生地黄（各七分）。不通畅者加酒大黄。里急后重者加木香，另磨槟榔。水煎服。
出汗不止：黄芪、黄连、黄柏、黄芩、生地黄、熟地黄、酸枣仁、当归，加浮小麦一撮，水煎服。
鼻出血：玄参、丹皮、生地黄、茅花（无茅花用根汁）、片黄芩、栀子、石膏（各等分），甘草（减半量），水煎，调入百草霜服用。
咽喉肿痛：黄连（二钱）、黄芩（二钱）、黄柏（一钱五分）、苦参（一钱）、玄胡索、乳香（各三分）、雄黄、孩儿茶（各五分）。以上药物研为细末，混合均匀，用芦管吹入喉中。
心神恍惚，夜间睡眠不安：黄连（二钱）、当归、生地黄、远志（甘草煮过剥去心）、茯神、人参、酸枣仁（炒）、丹参、柏子仁、石菖蒲、麦冬、甘草（炙，各一钱）。以上药物研为末，加入金箔三张，山药糊制成丸药，朱砂为衣，每次服用一钱，用灯心竹叶汤送下。
疹后痈毒，肢体关节肿痛：羌活、穿山甲（炒，研末，各一两）、金银花、白芷梢、大黄（各五钱）、甘草节（一钱）、乳香（制研，二钱）。以上药物研为末，每次服用一钱。用牙皂角刺同煎，酒调服，以发汗为度。
咽喉肿痛，无法进食：甘草、桔梗（各二钱）、玄参（一钱）、连翘、牛蒡子、射干、山豆根（各五分）。水煎服。
（前文提到的吹药方中加入薄荷、甘草、桔梗、玄参、山豆根末，蜜丸含化，效果良好。）
走马牙疳，牙龈黑烂：人中白、芦荟、使君子肉、龙胆草、胡黄连、五灵脂（各等分）。以上药物研为末，蒸饼为丸，如黍米大小，每次服用一钱，临睡前用白开水送服。

又一方：五倍子（研末，二钱）、雄黄（水飞，五钱）、枯矾（八分）、蚕蜕纸（烧灰，一钱）。以上药物研匀，先用温米泔水和乱发洗净患处，再敷药。（痘疹前后出现的急性牙疳，宜敷此药。若服药无效，导致两颊浮肿、穿孔溃烂而死的情况需注意。）
疹后水蓄证，因口渴时饮水过多所致。水停于胃则呕吐呃逆，入脾则肿胀，宜利水实脾，用猪苓、泽泻、茯苓、白术。水入肺则喘咳，加葶苈子。水入心则惊悸，宜用赤茯苓、木通。水入肝则胁痛，加芫花。水入肾、膀胱则小便不利，用车前子。疹后昼夜发热，毛发焦枯，皮肤干枯，肌肉消瘦，用清热丸（方见牙疳门主方）。如果忽然心腹绞痛并出汗，这是元气亏损，失于补养，虽然外表看似平静，但内虚未复，偶然中受恶气，多导致不治。以及睡中眼睛半睁，手足厥冷，欲作慢脾风，属于不治之证。
热盛导致失血：犀角地黄汤（方见血门）加三黄、栀子、茵陈、木通，以利小便泄火。
出疹期间吃鸡肉、鱼肉，会导致终身皮肤起粟粒状疙瘩，或在时行疹病时复发。吃猪肉，每年出疹的月份会患痢疾。吃盐醋，每年该月会咳嗽。吃五辛，则会生惊、发热不时，必须四十九日或百日之内忌口。
（贺千秋传）痘疮瘙痒或疼痛：桦树皮、乳香、茵陈混合均匀，烧熏及熏盖被子，立即停止。
痘疮腹泻，前三天毒火发作，用药重用黄连，痊愈。三天无效，则是痘疹后余毒引起的腹泻，用干柯根（即刀茅草根）煎汁服用可安。
痘疮气喘，用白花地丁煎服，痊愈。火痘毒盛，捣碎绞汁，和少许白酒浆服用，有效。
稀痘神方：金银花研末，砂糖调服，常年服用。或者将金银花连藤煎汤作为饮料。
痧疹气喘急促闷乱：西河柳研末（四钱），水调服可愈（在发疹药中加重用量，效果显著。疹后痢疾，用砂糖调西河柳粉服用。）
〔补遗〕惺惺散：小儿变蒸发热，痰嗽，风寒时疫，痘疹盛行，气机不和。
人参、白术、茯苓、芍药、桔梗、天花粉、细辛、甘草（各等分）。研为末，每次二钱，生姜、薄荷煎汤送服。热重者加柴胡。随证加减。
Rash (Zhen) belongs to Yang Toxicity. Upon infection, the condition is violent and fierce, causing significant harm with rapid transformations. Therefore, during the fever stage, it is most appropriate to resolve the exterior and disperse pathogens, ensuring the rash erupts thoroughly to avoid complications from residual toxicity and accumulated heat. If the exterior is not adequately released, or if blocked by wind-cold, or due to dietary errors or violation of taboos, even after the rash subsides, many residual symptoms may arise. After the rash, body temperature should naturally return to normal; if residual heat persists, careful differentiation based on specific symptoms is required. For vomiting, use the previous formula; for constipation, add prepared Rhizoma et Radix Pinelliae (Zhida Huang). Symptoms such as a chest protruding like a 'gui' shape, shoulder shrugging with panting, bleeding from mouth and nose, or a red or cyanotic/dark/withered complexion are all ominous signs. However, some cases involve lung deficiency where toxicity obstructs the airways causing continuous wheezing; in such cases, refer to the Zhisou Qingfei Fang (Stop Coughing and Clear Lung Formula). For day-and-night restlessness, delirium, and mania, the main formula is Tiao Liuyi San (Regulate Six-One Powder) (see Summer Heat section), taken with Chen Sha Dengxin Tang (Cinnabar and Juncus Decoction). For dark and scanty urine, use Wuling San (Five-Ingredient Powder with Poria) (see Urinary Obstruction section) added with Radix Scutellariae (Huangqin) and Radix Coptidis (Huanglian), decocted and mixed with Cinnabar.

Decoct in water and take.
(Note: The insufflation formula mentioned earlier can be enhanced by adding Menthae Haplocalycis Herba (Bohe), Glycyrrhizae Radix et Rhizoma (Gancao), Platycodonis Radix (Jiegeng), Scrophulariae Radix (Xuanshen), and Sophorae Radix (Shandougen) powder, formed into honey pills for sucking.)
**For Gangrenous Stomatitis (Zouma Yagan) with black/rotten gums:** Human Calcined Bone (Renzhongbai), Aloe (Luhui), Quisqualis Fructus (Shijunzi), Gentianae Radix et Rhizoma (Longdancao), Coptidis Rhizoma (Huhuanglian), Trogopterori Faeces (Wulingzhi) (equal parts). Grind into powder, make pills with steamed wheat cake paste, size of millet seeds. Take 1 qian per dose before bed with warm water.
**External Application Formula (for Gangrenous Stomatitis):** Realgar (water-ground, 1 qian), Phellodendri Cortex (powdered, 2 qian), Moschus (Muxiang) (5 li). Grind uniformly. First wash the area with Mugwort decoction, then apply the medicine.

Wash the area first with warm rice water and human hair, then apply. (For acute gangrenous stomatitis before/after chickenpox/smallpox. Apply externally. Note: If untreated, it may spread to cheek swelling and perforation leading to death.)
**Post-Rash Water Retention Syndrome:** Caused by excessive drinking when thirsty. Water stagnating in the Stomach causes vomiting/hiccups; entering the Spleen causes swelling. Treat by promoting urination and strengthening the Spleen using Polyporus (Zhuling), Alismatis Rhizoma (Zexie), Poria (Fuling), and Atractylodis Macrocephalae Rhizoma (Baizhu). Water entering the Lung causes asthma/cough; add Descurainiae Semen (Tingli). Water entering the Heart causes palpitations; use Red Poria (Chiling) and Akebiae Caulis (Mutong). Water entering the Liver causes hypochondriac pain; add Genkwa Flos (Yuanhua). Water entering the Kidney/Bladder causes difficult urination; use Plantaginis Semen (Cheqianzi).
If after the rash there is day-and-night fever, withered hair, dry skin, and emaciation, use Qingre Wan (Clear Heat Pill) (see Gangrenous Stomatitis section). If sudden colic with sweating occurs, this indicates Yuan Qi (Original Qi) depletion and lack of nourishment. Although the exterior seems calm, internal deficiency remains; accidental exposure to evil qi often leads to untreatable conditions. Also, sleeping with eyes half-open, cold extremities, and signs of Man Pi Feng (Slow Spleen Wind) are signs of untreatable conditions.
**Heat excess causing hemorrhage:** Xijiao Dihuang Tang (Rhinoceros Horn and Rehmannia Decoction) (see Blood section) added with San Huang (Three Yellows), Gardeniae Fructus (Zhizi), Artemisiae Scopariae Herba (Yinchen), and Akebiae Caulis (Mutong) to promote urination and drain fire.
Eating chicken or fish during the rash period causes lifelong skin eruptions resembling millet grains, or recurrence during epidemic rashes. Eating pork causes dysentery in the month corresponding to the annual rash occurrence. Eating salt and vinegar causes coughing in that month annually. Eating Five Pungent Spices causes fright and irregular fever; abstinence must be maintained for 49 or 100 days.
**(From He Qianqiu's transmission)** For itching or pain in smallpox: Birch bark, Resina Draconis (Ruxiang), and Artemisiae Scopariae Herba (Yinchén) mixed evenly, burned for fumigation and to smoke bedding, stops immediately.
For smallpox diarrhea: If within the first three days, toxic fire is erupting, use heavy doses of Radix Coptidis (Huanglian) to cure. If no effect after three days, it is diarrhea from residual toxicity after rash; decoct Gan Ke Gen (Dry Branch Root, i.e., Dao Mao grass root) and take the juice to settle.
For smallpox asthma: Decoct and take Baihua Di Ding (Hedyotis diffusa). For Fire Smallpox with intense toxicity, crush, extract juice, mix with a little white wine mash, and take; effective.
**Divine Formula for Mildening Rash:** Lonicerae Japonicae Flos (Jinyinhua) powdered, mixed with rock sugar, taken for years. Or boil Lonicerae Japonicae Flos with vines as tea.
**For Sha Rash with urgent asthma and distress:** Xihe Liu (Tamarix Ramulus) powdered (4 qian), mixed with water and taken to cure. (Add heavily to rash-inducing medicines for great effect. For post-rash dysentery, mix with rock sugar and take.)
[Supplement] **Xingxing San:** For pediatric transformation fever, phlegm-cough, wind-cold seasonal epidemics, widespread smallpox/rash, and disharmony of Qi.
Ginseng Radix (Renshen), Atractylodis Macrocephalae Rhizoma (Baizhu), Poria (Fuling), Radix Paeoniae (Shaoyao), Platycodonis Radix (Jiegeng), Trichosanthes Radix (Tianfen), Asari Radix et Rhizoma (Xixin), Glycyrrhizae Radix et Rhizoma (Gancao) (equal parts). Grind into powder, take 2 qian, decoct with Ginger and Mint. Add Bupleuri Radix (Chaihu) if heat is severe. Adjust according to symptoms.
