痧痘后与病后，气血皆虚，则肌肤薄嫩。若犯一切动风，鲜味，发物荤腥，助火生风，
或转走马牙疳，或风疹，痒疮，或外痈，遗毒。每有愈后，值其痧痘所发，节气复发。凡
乳孩，须乳母戒口为要。
小儿乃脆嫩弱质，淫风厉气，每能侵犯而发风疹。壮热，咳嗽，鼻塞，作呕，眼如
含泪，烦躁易啼，身现似针尖红点，此名风疹，非痧也。治法同痧。有一月发两次者，有
连接发三四次者。病孩与乳母，皆宜戒发物。
夏秋间，湿热蒸烁，浸淫人之肌表，发脓窠疮。皮薄起壳，顶空浆清，形似痘粒，易
破流水。但水淋处，烂如剥鳝，一用水洗，则串烂难图。他人粘近其疮，亦 肿烂皮，治
同HT 皮疮。
病后中虚，使脾不统血，无根之火，逼血上涌牙缝而出，脉虚弦，用六味汤加肉桂
三分，（方见后。因口不臭为别。）引火下降。误与苦寒制火，反大涌出不治。若胃经实火口
臭，脉数有力，宜投犀角地黄汤。
凡单方、毒药，非常用之品，误入腹不救。即如斑蝥、番木鳖、砒霜、 雄黄、马
蝗、水银、 砂、河豚、巴豆、轻粉、莽草、鸦片，此类尚多。
有种外感，初被凉药冰伏，邪气不出，使人烦闷，呕吐胸痞，多汗壮热，渴喜热饮，舌
面虽黄，舌底潮润，小便黄赤，皆邪内扰而然，不问一候外，或已二三候，仍宜用轻扬
品升托其邪，如桔梗，葛根、升麻、桑叶、苏梗、香附，一二帖自愈。
痧症、痘疹痊愈后，以及大病初愈阶段，人体气血均处于虚弱状态，肌肤变得薄嫩脆弱。此时若食用一切具有动风作用的、鲜美的、发物性质的荤腥食物，会助长火热、滋生内风，可能导致病情转化为走马牙疳（一种发展迅速、腐蚀严重的口腔疾病），或引发风疹、瘙痒疮疡，或导致外部痈肿、遗留毒邪。常常出现的情况是：病愈之后，恰逢原发病（痧痘）发作的节气，导致旧病复发。凡是哺乳期的婴儿，关键在于乳母必须严格忌口。
小儿体质本就脆嫩柔弱，外界的“淫风”（致病之风邪）和“厉气”（烈性疫气）容易侵犯身体而引发风疹。症状表现为：高热、咳嗽、鼻塞、恶心呕吐、眼睛像含着泪水一样、烦躁不安且容易啼哭、身上出现类似针尖大小的红点。这叫做风疹，不是痧症。治疗方法与痧症相同。有的患儿一个月发作两次，有的接连发作三四次。患病的小儿和乳母，都应当忌食发物。
夏秋季节，湿热之气蒸腾灼烧，浸淫于人的肌表，从而引发脓窠疮（一种化脓性皮肤病）。皮损皮薄起壳，顶部空虚、浆液清稀，形状类似痘粒，容易破裂流水。但是水流出的地方，糜烂得像剥了皮的鳝鱼一样，一旦用水清洗，就会蔓延溃烂，难以治疗。他人如果靠近接触其疮口，皮肤也会肿胀溃烂。治疗方法同于HT皮疮（此处原文可能有误或指代特定疮疡，暂按原文保留，通常指类似黄水疮等传染性皮肤病）。
大病初愈时中焦脾胃虚弱，导致脾脏不能统摄血液，无根之火逼迫血液向上涌出，从牙缝中渗出，脉象虚弦。治疗应使用六味地黄汤加入三分肉桂（方剂见后文。以此区别于口不臭的情况），以引火下行。如果错误地使用苦寒药物来压制火势，反而会导致出血不止，无法救治。如果是胃经实火导致的口臭，脉象数而有力，适宜投用犀角地黄汤。
凡是单方、毒药，不属于常用药物的品种，误服入腹后无法挽救。例如斑蝥、番木鳖（马钱子）、砒霜、雄黄、蚂蝗、水银、硇砂、河豚、巴豆、轻粉、莽草、鸦片等，这类药物还有很多。
有一种外感病，起初被凉药冰伏（寒凉药物遏制了邪气外出），导致邪气无法排出，使人感到烦闷、呕吐、胸脘痞满、多汗、高热、口渴但喜欢喝热饮。舌面虽然发黄，但舌底潮湿润泽，小便黄赤，这都是邪气内扰所致。无论病程已过一候（五天），还是已经过了两三个候，仍然适宜使用性质轻扬的药物升提托举邪气外出，如桔梗、葛根、升麻、桑叶、苏梗、香附等，服用一两帖即可自愈。
After the recovery from sha disease (a group of acute febrile diseases characterized by skin eruptions) and smallpox, or after recovering from a severe illness, both Qi and Blood are deficient, making the skin thin and tender. If one consumes foods that stir wind, are rich/fresh, are "fa wu" (triggering foods), or are greasy/meaty items, it will aid fire and generate wind. This may transform into zou ma ya gang (gangrenous stomatitis progressing rapidly), wind rash, itching sores, external carbuncles, or leave behind toxic residues. It is common for relapses to occur after recovery when the season coincides with the original onset of sha or smallpox. For nursing infants, it is crucial that the wet nurse strictly observes dietary restrictions.
Children possess fragile and weak constitutions; pathogenic winds ("yin feng") and virulent qi ("li qi") can easily invade and trigger wind rash. Symptoms include high fever, cough, nasal congestion, vomiting, eyes appearing teary, irritability, frequent crying, and the appearance of pinpoint-sized red spots on the body. This is termed wind rash, not sha disease. The treatment method is the same as for sha disease. Some children may experience two episodes in a month, or three to four consecutive episodes. Both the sick child and the wet nurse should avoid triggering foods.
During summer and autumn, damp-heat steams and scorches, infiltrating the body's surface and causing pustular sores (nong ke chuang). The lesions have thin skin with crusts, hollow tops with clear serum, resembling smallpox vesicles, and are prone to rupture and weeping. However, areas where fluid leaks become ulcerated like skinned eels; washing with water causes spreading and difficult-to-treat erosion. Contact with others' skin near the sores also causes swelling and erosion. Treatment is similar to HT pi chuang (likely referring to specific contagious impetigo-like conditions).
Following a severe illness, middle-jiao deficiency leads to the Spleen's failure to control blood. Rootless fire forces blood upward, causing bleeding from the gum margins. The pulse is deficient and wiry. Treatment involves Liuwei Tang (Six-Ingredient Rehmannia Decoction) added with 3 fen of Rougui (Cinnamon Bark) (formula seen later; distinguished by the absence of foul breath) to guide fire downward. Mistakenly using bitter-cold herbs to suppress fire instead causes massive hemorrhage that is incurable. If there is excess fire in the Stomach channel manifesting as foul breath and a rapid, forceful pulse, Xijiao Dihuang Tang (Rhinoceros Horn and Rehmannia Decoction) is appropriate.
Any single prescriptions or toxic drugs that are not commonly used, if mistakenly ingested, cannot be saved. Examples include Banmao (Mylabris), Fanmubie (Strychnos Nux-vomica), Pishuang (Arsenic Trioxide), Xionghuang (Realgar), Mahuang (Leech - note: text says Ma Huang but context implies Leech/Ma Hui or similar, usually Ma Hui in this context of toxicity, but literal is Horse Leech/Water Leech), Shuiyin (Mercury), Naoshan (Ammonium Chloride/Nitre), Hetun (Pufferfish), Badou (Croton Seed), Qingfen (Calomel), Mangcao (Aconite root of other species/Toxic herb), Yapians (Opium). There are many such substances.
There is a type of exterior contraction initially suppressed by cold-natured medicines ("bing fu"), trapping the pathogenic factor inside. This causes restlessness, vomiting, chest fullness, profuse sweating, high fever, thirst preferring hot drinks. Although the tongue coating is yellow, the tongue body underneath is moist. Urine is yellow and red. These are all due to internal disturbance by pathogens. Regardless of whether one week (yi hou) or two to three weeks have passed, it is still appropriate to use light and ascending herbs to lift and expel the pathogen, such as Jiegeng (Platycodon Root), Gegen (Pueraria Root), Shengma (Cimicifuga Rhizome), Sangye (Mulberry Leaf), Sugeng (Perilla Stem), and Xiangfu (Cyperus Rhizome). One or two doses will result in self-healing.
