遗毒，是指婴儿在母体胞胎中禀受了父母精血中的遗留毒邪。因此出生后，若用热水洗浴，或穿着经烘烤熏蒸过的衣物，外部的热邪触动体内之毒，会导致肌肉腐烂破溃，患儿啼哭不安，治疗应当尽早进行。内服土茯苓汤，调入人中黄细末四至五分服用，每日进药数次。对于外部腐烂破溃的部位，用蜜炙过的黄柏细末直接干撒涂抹；或者将滑石粉、绿豆粉铺在席子上让患儿躺卧，这样可挽救三到四成的生命。如果婴儿的毒邪蔓延至全身，日夜啼哭，不吃奶也不喝水，这是毒邪炽盛而正气衰弱的表现，已无法救治。
疠风，是有毒的风邪所致。脾主司肌肉，肺主司皮毛。肌肉受到湿热侵袭，导致气机浑浊、血液亏虚，又外感猛烈暴戾的风寒之邪，日久导致四肢蜷曲挛缩，肌肉腐败坏死。热毒炽盛时，面部会出现油光；热邪久留则生虫。虫蚀五脏会导致形体出现五种损伤：侵蚀肝脏则眉毛脱落，侵蚀肺部则鼻梁崩塌，侵蚀心脏则声音嘶哑，侵蚀脾脏则足底穿孔、膝盖虚肿，侵蚀肾脏则耳鸣如蝉鸣，或瘙痒疼痛如针刺；侵蚀身体则皮肤瘙痒如虫爬行。治疗时，必须立即令患者戒除酒色，保持心态平和宽容，一切能诱发风邪、扰动气机的食物，如酱料、盐、花椒、醋、荤腥肉类、烧烤炸物以及大寒大热的食物，都应禁忌，只吃清淡的米饭、白粥和白煮的时令蔬菜即可。方药用一条酒杯大小的蛇，用竹刀剖开腹部去除杂质，切成寸段，取一块瓦片仰放在炭火上，将蛇段竖放于瓦上，蛇段跌倒的是无毒的部分，丢弃不用；不倒下的为有毒部分，将其炙烤至存性后研为细末。（按语：蛇是灵物，不可随意杀害。应当使用白花蛇条，经酒浸后炙烤研末来替代。虽然其力量不如活蛇猛烈，但在走窜搜剔风邪方面也是非劣等的药物，一次未愈，不妨再用一次。据称白花蛇是草蛇类。）对于已经溃烂长久、腐烂不堪的患者也有效。之后接续服用易老驱风丸、东坡四神丹，常服不可间断。然而此病必须戒除色欲，禁止口服辛辣及发物，痊愈后也必须坚守禁忌一年多，否则复发便无药可救。

Yidu (Residual Toxin) refers to the residual toxin inherited from the parents' essence and blood while the infant is in the womb. Therefore, after birth, if bathed with hot water or dressed in clothes that have been baked or fumigated, external heat may stir up internal toxins, causing muscle rot and ulceration, leading to restless crying. Treatment should be initiated early. Internally, administer Tufuling Decoction (Smilax Glabra Decoction) mixed with 4-5 fen of fine powder of Renzhonghuang (Human Excrement Yellow), taken several times a day. For external ulcers, apply dry powder of honey-fried Huangbai (Phellodendron Bark). Alternatively, spread Huashi (Talcum) and Lvdoufen (Mung Bean Powder) on the mat for the infant to lie on; this method can save three or four out of ten cases. If the toxin spreads throughout the body, causing day-and-night crying and refusal to nurse or drink, it indicates excessive toxin and deficient healthy qi, rendering it incurable.
(Also known as Laidafeng [Great Leprosy], commonly called Dama Feng [Big Leprosy].)
Lifeng (Leprosy) is caused by toxic wind pathogens. The Spleen governs muscles, and the Lung governs skin and hair. When muscles are affected by damp-heat, qi becomes turbid and blood becomes deficient. Combined with external exposure to fierce and violent cold-wind pathogens, this leads over time to curling and contracture of the limbs and corruption of muscles. When heat-toxin is excessive, the face appears oily; prolonged heat generates worms. Worm erosion of the five zang organs causes five types of physical damage: erosion of the Liver causes eyebrow loss; erosion of the Lung causes nasal collapse; erosion of the Heart causes hoarseness; erosion of the Spleen causes perforation of the soles and swelling of the knees; erosion of the Kidney causes tinnitus like cicada chirping, or itching and pain like needle pricks; erosion of the body causes skin itching like insects crawling. In treatment, the patient must immediately abstain from alcohol and sexual activity, maintain a calm and open mind, and strictly avoid all foods that trigger wind or agitate qi, such as sauces, salt, pepper, vinegar, meat, fried/grilled foods, and extreme cold or hot substances. Only light rice, plain congee, and boiled seasonal vegetables should be consumed. The prescription uses one snake the size of a wine cup, cut open with a bamboo knife to remove impurities, and sliced into inch-long segments. Place a tile upside down over charcoal fire, stand the snake segments vertically on the tile. Segments that fall off are non-toxic and should be discarded; those that remain standing are toxic. Process these by roasting until "preserving nature" (charred but retaining efficacy) and grind into powder. (Note: Snakes are spiritual creatures and should not be killed wantonly. It is recommended to use Baihua She [Bungarus multicinctus] strips, soaked in wine, roasted, and ground. Although less potent than live snakes, its ability to penetrate and search out wind is excellent. If one course is ineffective, another may be tried. It is said Baihua She is a grass snake.) This is also effective for long-standing ulcers that are severely rotten. Subsequently, continuously administer Yilao Qufeng Wan (Yilao Wind-Expelling Pill) and Dongpo Sishen Dan (Dongpo Four-God Elixir) without interruption. However, this condition requires strict abstinence from sexual desire and prohibition of spicy and "fa-wu" (stimulating/allergic) foods. Even after recovery, one must observe these restrictions for over a year; otherwise, relapse will be incurable.
