凡疹疮发表之后，红影出于肌肤，切戒风寒生冷。如一犯之，则皮肤闭密，毒瓦斯壅滞，遂变浑
身青紫，而毒反内攻，烦躁腹痛，气喘闷乱，诸证作矣。欲出不出，危亡立至，医家病家皆不可不
慎。
一、疹疮之证，全在调治，禁忌如鸡鱼炙爆，盐醋五辛之类，直过七七之后方可食之，惟宜食
淡，不可纵口，致生他疾也。若误会鸡鱼，则终身皮肤粟起如鸡皮之状。或遇天行出疹之时，又令
重出；误食猪肉，则每岁凡遇出疹之月，多有下利；误食盐醋，致令咳嗽，则每岁出疹之月，必多
咳嗽；误食五辛之物，则不时多生惊热，此痘疹之家皆所当慎也。
疮疹非热不出。凡疹子欲出，必遍身发热或烦躁，或头眩，或身体拘急。及既出则身便凉，诸
证悉解，此一层疹子随即收者，极轻者也。如疹子既出而热甚不减，此毒盛者也，宜大青汤解其毒
。便涩者，宜黄连解
毒汤合白虎汤，或大连翘饮解其里。大便不通者，《局方》凉膈散加牛蒡子主之。
凡疹证多嗽，此顿出顿入之势也。但有疹毒，须假嗽多而散，故疹后旬日之内，尚宜有嗽，切
不可见嗽多而治嗽也，宜慎之。疹证属肺与脾胃，肺受火邪则嗽多，嗽多则顿出头面并及四肢；大
肠受火邪，则上连脾胃而为泄泻。若早泻则嗽必减而变为喘，盖喘嗽二者皆属于肺。然嗽实喘虚，
得嗽者出，得喘者入，入则合眼多痰，胸满腹胀，色白而毒不尽出，证则危矣。此疹之宜嗽不宜喘
，而最不宜于泄泻也。
凡是疹疮在发表（通过发汗等方法使邪气从体表排出）之后，红色的疹影出现在肌肤表面，必须严格戒除风寒和生冷食物。一旦触犯，就会导致皮肤毛孔闭塞紧密，毒气壅滞不通，进而变成全身青紫色，而且毒气反而向内攻陷，出现烦躁、腹痛、气喘闷乱等症状，各种危重证候就会发作。疹子想出来却出不来，危险和死亡立刻就会到来，医生和病人都不能不谨慎。
一、疹疮这类病症，关键在于调理治疗，禁忌事项包括鸡肉、鱼肉、油炸烧烤食品以及盐、醋、五辛（指葱、蒜、韭、薤、兴渠等五种有辛辣气味的蔬菜）之类，直到过了七七四十九天之后才可以食用，只适宜吃清淡的食物，不可放纵口腹之欲，以致引发其他疾病。如果误食鸡肉和鱼肉，会导致终身皮肤粗糙隆起，像鸡皮疙瘩一样。或者遇到时行疫病出疹的时候，又会让疹子复发；误食猪肉，则每年遇到出疹的月份，大多会出现腹泻；误食盐和醋，导致咳嗽，则每年出疹的月份，必定会多咳嗽；误食五辛之物，则不时会产生惊风发热，这是痘疹患者家庭都应当谨慎的事项。
疮疹不是热象就不会发出。凡是疹子想要发出，必然全身发热或者烦躁，或者头晕目眩，或者身体拘挛紧急。等到疹子发出后，身体就会变凉，各种症状全部解除，这一类疹子随即消退的，属于极轻的病症。如果疹子已经发出但热势依然很盛不减退，这是毒气旺盛的表现，适宜用大青汤来解毒。小便涩痛不畅的，适宜用黄连解毒汤合白虎汤，或者大连翘饮来清解里热。大便不通畅的，《局方》中的凉膈散加牛蒡子主治。
凡是疹证大多伴有咳嗽，这是疹毒顿然发出又顿然入里的趋势。但是只要有疹毒，必须依靠咳嗽多来发散毒气，所以在疹子发出后的十天之内，仍然应该有些许咳嗽，千万不要见到咳嗽多就单纯去治咳嗽，这一点要谨慎。疹证归属于肺和脾胃，肺受到火邪侵袭就会咳嗽多，咳嗽多则疹毒顿然出头面并波及四肢；大肠受到火邪侵袭，则向上连及脾胃而导致泄泻。如果过早发生泄泻，咳嗽必然会减少而转变为气喘，因为气喘和咳嗽都归属于肺。然而，咳嗽属实证，气喘属虚证，得到咳嗽说明疹毒向外发散，得到气喘说明疹毒向内收敛，向内收敛则闭眼多痰，胸满腹胀，面色苍白而毒气不能完全发出，证候就非常危险了。这就是疹证适宜咳嗽而不适宜气喘，最不宜于泄泻的原因。
After the exterior-releasing treatment for variola/rubella (Zhen Chuang), when red rashes appear on the skin, one must strictly avoid wind-cold and raw/cold foods. If violated, the skin pores will become closed and tight, causing toxic factors to stagnate, leading to a purple-blue discoloration of the whole body, with toxins attacking inwardly, resulting in restlessness, abdominal pain, asthma, and confusion, thereby triggering various critical syndromes. If the rash attempts to emerge but fails to do so, danger and death are imminent; both physicians and patients must exercise utmost caution.
1. The management of Zhen Chuang relies entirely on proper regulation and treatment. Taboos include chicken, fish, fried/grilled foods, salt, vinegar, and "Five Pungent Spices" (Wu Xin, referring to pungent vegetables like garlic, scallions, etc.). These may only be consumed after forty-nine days (seven sevens) have passed. A bland diet is recommended; one must not indulge the palate, lest other diseases arise. Misconsumption of chicken or fish may cause lifelong rough, bumpy skin resembling gooseflesh. During epidemic outbreaks of Zhen, misconsumption may trigger recurrence. Misconsumption of pork often leads to diarrhea during the months corresponding to previous Zhen episodes. Misconsumption of salt or vinegar causes coughing, which recurs annually during those same months. Misconsumption of Five Pungent Spices induces frequent fright-heat. These are matters that families dealing with smallpox/rubella must heed.
Sores and rashes do not erupt without heat. When Zhen Zi (childhood exanthem) is about to erupt, there is invariably generalized fever, restlessness, dizziness, or bodily stiffness/spasms. Once erupted, the body cools down, and all symptoms resolve. This type, where the rash subsides immediately, is extremely mild. If heat persists strongly after eruption, it indicates abundant toxins; Da Qing Tang (Great Blue Decoction) should be used to resolve toxins. For difficult/dysuric urination, Huang Lian Jie Du Tang (Coptis Decoction for Resolving Toxins) combined with Bai Hu Tang (White Tiger Decoction), or Da Lian Qiao Yin (Large Forsythia Drink), should be used to clear interior heat. For constipation, Liang Ge San (Cool the Diaphragm Powder) from *Ju Fang* (Prescriptions of the Imperial Medical Bureau) added with Niu Bang Zi (Arctii Fructus) is indicated.
Zhen syndromes frequently involve coughing, reflecting the pattern of sudden eruption and sudden internalization. However, as long as Zhen toxins exist, profuse coughing is necessary to disperse them. Therefore, within ten days post-eruption, some coughing is expected. One must not treat the cough merely because it is frequent; this requires caution. Zhen syndromes relate to the Lung and Spleen/Stomach. If the Lung is affected by Fire Evil, coughing increases, causing the rash to suddenly appear on the face/head and spread to the limbs. If the Large Intestine is affected by Fire Evil, it connects upward to the Spleen/Stomach, causing diarrhea. If diarrhea occurs too early, coughing decreases and transforms into asthma/wheezing, as both asthma and cough belong to the Lung. Cough represents excess (Shi), while asthma represents deficiency (Xu). Cough indicates outward dispersion of toxins; asthma indicates inward contraction. Inward contraction manifests as closed eyes with excessive phlegm, chest fullness, abdominal distension, pale complexion, and incomplete toxin expulsion, indicating a critical condition. Thus, Zhen favors cough over asthma, and most of all, avoids diarrhea.
