夫小儿之有胎火胎毒何也？或其父醉酒入房而得胎孕；或既孕之后，房欲不禁，内蕴火
毒；又或其母滋味过浓，忿怒无节，惊喜不时，火热燔灼，营血不清，儿在胎中吸饮秽浊。
此皆先天受毒，致产后，或月内，或月余，其毒骤发。痛楚号泣，臀腿 红紫晕，其肤碎裂
，状如刮痧，或遍体 赤，或口糜难乳，或咽肿音哑。若不急治，毒即内陷，腹满气逆，致
成胎惊而毙者多矣。治以生大黄磨浓汁，调入西黄末，再以金银花、芦根、甘草、钩钩，煎
汤冲服，得大便泻后，其火自退，毒瓦斯外泄，即可调理而愈。
如或臀肿 烂，红赤无皮，或亦有 赤遍体者，此即名猴狲疳。缘其父曾患下疳杨梅恶
疾，服轻粉升药，遏抑毒瓦斯在内，故遗毒于胎元，须以猴疳化毒丹治之，四、五十服可愈。
设或晚治，毒瓦斯浸淫，亦必内陷，渐致形瘦神怯，音哑鼻塞，气逆腹满而不可救，慎之慎之
！
赤游丹者，乃心火内郁，三焦风热乘之，故发于肌肤之表，风胜则树木皆摇，故令游走
殊速。名之丹者，以应心火而色赤也，形如云片，上起风粟，作痒而痛，或发于手足，或发
于头面胸背，令儿躁闷腹胀，发热，游走遍体，流行甚速，须急治之。自腹而流于四肢者，
易治；自四肢而归于腹者，难疗。治宜凉心泻肝，如龙胆泻肝汤、犀角地黄汤之类。又当顺
天时，若暑热，以通圣辛凉之剂解之；严寒，以升麻、葛根辛温之剂解之。外宜用磁锋砭去
紫血，以泄其毒，再用精肉片贴之；或用鸡子清调乳香末涂之亦可。又有色白者，名白游风
，其候流块作痒，大小不等，津水作烂，此感风湿而发，治以疏散渗湿为主。
游火者，或头面，或腿上，红赤肿热，流散无定，以碱水扫上，旋起白霜者是也，其色
光亮，其热如火。治宜疏风清火、凉血解毒，外用白海蜇皮洗净拭干，包扎患处一伏时，揭
开看，如蜇皮黄枯，即另换一张包裹，如此三、四张，即消散矣。
小儿为何会有胎火和胎毒呢？有的因为父亲醉酒行房而受孕；或者怀孕之后，房事不加节制，体内蕴积火毒；又或者是母亲饮食滋味过于浓厚，愤怒没有节制，惊喜无常，导致火热燔灼，营血不纯净，胎儿在母腹中吸收饮用了这些秽浊之气。这些都是先天受毒，导致出生后，或一个月内，或一个多月后，毒气突然发作。患儿疼痛哭闹，臀部和大腿出现红紫晕斑，皮肤碎裂，状如刮痧，或者全身发红，或者口腔糜烂难以吃奶，或者咽喉肿痛声音嘶哑。如果不紧急治疗，毒气就会内陷，腹部胀满气逆，导致形成胎惊而死亡的很多。治疗用生大黄磨成浓汁，调入西黄（牛黄）末，再用金银花、芦根、甘草、钩藤煎汤冲服，大便泻下后，火气自然消退，毒气向外排泄，就可以调理而痊愈。
如果臀部肿胀溃烂，红赤无皮，或者也有全身发红的，这就名叫猴狲疳。这是因为父亲曾患下疳杨梅等恶疾，服用轻粉、升药，遏制毒气在内，所以将余毒遗留给胎儿，需要用猴疳化毒丹治疗，服用四五十剂可以痊愈。如果治疗晚，毒气浸淫，也必然内陷，逐渐导致形体消瘦精神怯弱，声音嘶哑鼻塞，气逆腹胀而无法救治，务必谨慎！
赤游丹，是心火内郁，三焦风热乘虚侵袭，所以发于肌肤表面，风邪盛则树木摇晃，所以令其游走速度特别快。命名为“丹”，是因为对应心火且颜色发红，形状像云片，上面起风疹粟粒，又痒又痛，或者发于手足，或者发于头面胸背，使患儿烦躁闷乱腹胀，发热，游走遍体，流行非常快，必须紧急治疗。从腹部流向四肢的，容易治疗；从四肢流回腹部的，难治。治疗宜凉心泻肝，如龙胆泻肝汤、犀角地黄汤之类。又应当顺应天时，如果是暑热，用通圣散辛凉之剂解表；严寒，用升麻、葛根辛温之剂解表。外用磁锋砭石刺破放出紫血，以泄其毒，再用精肉片贴敷；或者用鸡蛋清调乳香末涂抹也可以。又有颜色白的，名叫白游风，其症状为流块作痒，大小不等，津水渗出溃烂，这是感受风湿而发，治疗以疏散渗湿为主。
游火，或者头面，或者腿上，红赤肿热，流散无定形，用碱水扫在上面，随即起白霜的就是这种病，其色光亮，其热如火。治疗宜疏风清火、凉血解毒，外用白海蜇皮洗净拭干，包扎患处一个时辰，揭开看，如果海蜇皮变黄枯，就另换一张包裹，如此三四张，就消散了。
Why do infants have fetal fire and fetal toxin? It may be due to conception after the father engaged in sexual intercourse while drunk; or after pregnancy, if sexual desire is not restrained, internal accumulation of fire toxin occurs; or it may be that the mother consumes overly rich flavors, lacks emotional regulation (anger), and experiences unpredictable joy or surprise, causing fierce burning of fire-heat, leading to impure Ying blood (nutritive blood). The fetus absorbs these turbid substances in utero. These are all cases of congenital toxin acquisition, which manifest suddenly after birth, either within one month or a few months later. The infant cries in pain, with red-purple halos on the buttocks and legs, skin cracking resembling scraping (Gua Sha), or generalized erythema, oral ulceration making breastfeeding difficult, or swollen throat and hoarseness. If not treated urgently, the toxin will sink inward, causing abdominal distension and rebellious Qi, often resulting in death from fetal convulsions. Treatment involves grinding raw Radix et Rhizoma Rhei (Dahuang) into a thick juice, mixing in powdered Bovis Calculus (Xihuang), and decocting Flos Lonicerae Japonicae (Jinyinhua), Radix Phragmitis Communis (Lugen), Radix Glycyrrhizae Uralensis (Gancao), and Uncaria rhynchophylla (Gougou) to make a decoction for flushing down the powder. After bowel evacuation, the fire subsides naturally, and the toxin is expelled outward, allowing for recovery through conditioning.
If there is swelling and ulceration of the buttocks, redness without skin, or generalized erythema, this is named Monkey Sores (Housun Gan). This originates from the father having previously suffered from chancre or syphilis-like diseases, taking Calomel (Qingfen) and Arsenolite (Shengyao), which suppressed the toxin internally, thereby transmitting residual toxin to the fetal origin. It must be treated with Hougan Huadu Dan (Monkey Sore Toxin-Resolving Pill); forty to fifty doses can lead to cure. If treatment is delayed, the toxin spreads invasively and sinks inward, gradually leading to emaciation, timidity, hoarseness, nasal congestion, rebellious Qi, and abdominal distension, becoming incurable. Be extremely cautious!
Chi You Dan (Red Roaming Erysipelas) arises from internal depression of Heart Fire, compounded by Wind-Heat in the San Jiao (Triple Burner) invading from outside, thus manifesting on the surface of the skin. When Wind is predominant, it causes rapid movement, like trees shaking in the wind. It is named "Dan" because it corresponds to Heart Fire and appears red. Its shape resembles cloud patches, rising with wind-rash granules, causing itching and pain. It may appear on the hands and feet, or on the head, face, chest, and back, causing irritability, abdominal distension, fever, and rapid roaming throughout the body. Urgent treatment is required. Cases flowing from the abdomen to the limbs are easy to treat; those flowing from the limbs back to the abdomen are difficult to cure. Treatment should cool the Heart and drain the Liver, using formulas such as Longdan Xiegan Tang (Gentian Liver-Draining Decoction) or Xijiao Dihuang Tang (Rhinoceros Horn and Rehmannia Decoction). One must also conform to the seasons: in summer heat, use the acrid-cool agent Tongsheng San (Unimpeded Salvation Powder) to resolve the exterior; in severe cold, use acrid-warm agents containing Cimicifugae Rhizoma (Shengma) and Puerariae Lobatae Radix (Gegen) to resolve the exterior. Externally, use a magnetic lancet to pierce and release purple blood to vent the toxin, then apply slices of lean meat; alternatively, mix Frankincense Resin (Ruxiang) powder with egg white for topical application. There is also a white variant named Bai You Feng (White Roaming Wind), characterized by migrating lumps, itching, varying sizes, and weeping ulcers, caused by Wind-Damp invasion. Treatment focuses on dispersing Wind and leaching out Dampness.
You Huo (Roaming Fire) presents as red, hot, swollen areas on the head, face, or legs, spreading不定ly. Applying alkaline water causes a white frost to form immediately; the color is bright and the heat feels like fire. Treatment requires dispersing Wind, clearing Fire, cooling Blood, and resolving toxicity. Externally, wash and dry white Sea Cucumber (Bai Haizhe) skin, apply it to the affected area for one shichen (two hours), remove it, and if the skin turns yellow and dry, replace it with a fresh piece. Repeating this three or four times leads to resolution.
