小儿一岁以内，身发赤游风者，皮上如丹涂之状，故谓之丹。一切紫赤丹瘤，总由孕母
血热留胎，热毒蕴于腠理；或乳母好酒、嗜辛、喜啖炙爆；或烘晒热衣即与包裹，柔嫩肌肤
感受热毒所致。发于四肢易治，入腹入囊皆难疗也。发于头面胸背，身如火灼，烦躁胀闷者
，古谓之入心，必死。治法用朴硝、大黄、青黛为末，新汲水调敷。或芭蕉根捣汁涂之，干
则再涂。冬月畏冷稍温涂，极妙。
无论赤白丹毒，如用寒凉药涂之不效者，即取灶心土研极细末，以熟鸡蛋黄熬取油调涂

黑，则其油自出。

另外，抱头火丹的方子：先用砭石刺破排出火毒之血，然后将炒黑山栀、大黄、雄黄按等分研成粉末，用水调匀后敷贴。或者用鸡蛋白调匀雄黄敷贴，也有效。
另外，水蛇火丹的方子：使用灶心土，加水磨成浆液涂抹，片刻后水汽干涸，药面重新变得潮湿，这是泡中的毒水排出的表现，毒水拔尽即愈。如果之前已经挑破，再加六一散等量敷贴，就会结疤。
小儿一岁以内，身上发生赤游风的，皮肤上像丹砂涂抹一样的形状，所以称为丹。一切紫红色的丹瘤，总归是因为孕妇血热留于胎中，热毒蕴藏在腠理；或者是乳母喜欢喝酒、嗜好辛辣、喜欢吃烤炸食物；或者是刚烘晒热的衣服就包裹婴儿，导致柔嫩的肌肤感受热毒所致。发于四肢容易治疗，进入腹部或阴囊都难以治愈。发于头面胸背，身体如火烧灼，烦躁胀闷的，古代称为入心，必定死亡。治疗方法是用朴硝、大黄、青黛研成粉末，用新打的井水调匀后敷贴。或者用芭蕉根捣汁涂擦，干了再涂。冬天怕冷时稍微温热后涂抹，非常妙。
无论是赤色还是白色的丹毒，如果使用寒凉药物外敷无效，就取灶心土研成极细粉末，用熟鸡蛋黄熬取的油调匀涂抹，必定有效。
另外，小儿火毒赤游的方子：将韭菜地里的蚯蚓粪研细，用麻油调匀搽擦，立刻痊愈；或者将蚯蚓灰存性，加入少许冰片，用鸡蛋白调匀敷贴也有效。

另外，取三十个鸡蛋，煮熟后去掉蛋白，将蛋黄炒出油，取油涂抹，立刻见效。取鸡蛋油的方法：将蛋黄炒至黑色，油自然流出。
另一个方子：明雄黄三钱，人中白一钱半，青黛五分，冰片三分，共同研成细末，蚯蚓粪（粗壮的为佳）用六钱（如果湿的用一两），研细混合均匀，用童子尿调匀涂抹数次即愈，重症需要涂抹数日才能痊愈。
另一个方子：取多年粪坑底部的砖块研成粉末，用麻油调匀涂抹，极其有效。

另外，初生婴儿手足红赤，名叫游风流火。如果从脚起蔓延至小腹，从手起蔓延至胸膛，大多无法救治，急忙用此方抢救。马兰头不拘多少，用水洗去泥土，捣碎绞汁搽擦患处，干燥了再搽，屡用屡效。冬天没有叶子用根也可以。
另一个方子：或者将大白菜、小白菜捣烂敷贴患处。
另外，或者用风菱角壳烧炭存性研成粉末，用麻油调匀搽擦，均极其神效。
Castor seeds (Ricini Semen) are peeled and ground into a paste, mixed evenly with water from grinding rusty iron, and applied in concentric circles around the red area. Once dry, it is immediately reapplied in circles until healed.
For erysipelas starting from the back or head, juice pressed from *Allium fistulosum* var. *gaudichaudianum* (Wacon) is applied as a poultice.
Another method: Prick the red area with a needle to release foul blood. Alternatively, grind *Hanshui Shi* (Halloysitum Rubrum) into powder, mix with oil, and apply.
Additionally, fresh leaves of *Platycladi Cacumen* (Ce Bai Ye) and Wacon are pounded together, mixed with powdered *Rhei Radix et Rhizoma* (Da Huang), blended with vinegar, and applied for immediate cure.
Furthermore, for "Ghost Face Erysipelas," characterized by frequent pus and blood on the face and unbearable itching, use two qian of *Calamina* (Lu Gan Shi) [quenched three times in *Coptidis Rhizoma* (Huang Lian) juice], [text missing].
Also, for "Ant Erysipelas": Grind *Rhei Radix et Rhizoma* (Da Huang) and stir-fried *Manis Squama* (Chuan Shan Jia) into powder, mix with juice from *Euphorbia lathyris* seed (Mu Bei Zi), and apply.
Also, for "[Missing Character] Erysipelas": For cases with abdominal masses and alternating chills and fever, pound one liang of *Coicis Radix* (Yi Yi Ren Gen), decoct with one cup of water and one cup of wine, and take on an empty stomach; cured after two doses.
Also, for "Head-Embracing Erysipelas": First, use a stone lancet to bleed out the fire-toxic blood. Then, mix equal parts of stir-fried black *Gardeniae Fructus* (Shan Zhi), *Rhei Radix et Rhizoma* (Da Huang), and *Realgar* (Xiong Huang) into powder, mix with water, and apply. Alternatively, mix *Realgar* with egg white and apply; also effective.
Also, for "Water Snake Erysipelas": Use *Caosin Tu* (Furnacis Argilla) ground with water for application. After a short while, when the moisture dries and the medicine becomes damp again, it indicates that the toxic fluid from the blisters is being expelled; once fully drained, it heals. If previously punctured, add equal parts of *Liuyi San* (Six-One Powder) for application to form scabs.
In infants under one year old, if red wandering wind occurs, appearing like painted cinnabar on the skin, it is called Dan. All purple-red Dan tumors are generally caused by maternal blood heat retained in the fetus, with heat-toxin accumulating in the interstices; or due to the nursing mother's preference for alcohol, spicy foods, and fried items; or wrapping the infant in freshly heated clothes, causing tender skin to contract heat-toxin. Cases on the limbs are easy to treat; those entering the abdomen or scrotum are difficult. Those on the head, face, chest, and back, accompanied by burning sensation, irritability, and distension, were anciently termed "entering the heart" and are fatal. Treatment involves mixing *Muxiao* (Natrii Sulfas), *Rhei Radix et Rhizoma* (Da Huang), and *Qingdai* (Indigo Naturalis) into powder, applying with fresh well water. Alternatively, apply juice from *Musa Basjoo* root (Bajiao Gen); reapply when dry. In winter, warming the application slightly before use is excellent.
For both red and white Dan toxicity, if cold-natured topical medicines fail, grind *Caosin Tu* (Furnacis Argilla) into fine powder, mix with oil rendered from cooked egg yolks, and apply; this is highly effective.
Additionally, for infant fire-toxin red wandering: Grind earthworm feces from leek fields, mix with sesame oil, and rub for immediate cure; or use calcined earthworm ash with a little borneol, mixed with egg white for application; also effective.
Additionally, for infant red wandering erysipelas spreading over the whole body to the heart and chest (uncurable): Dissolve *Mangxiao* (Natrii Sulfas) in warm water, take the concentrated liquid to wipe the erysipelas; highly effective.
Additionally, take thirty eggs, boil them, remove whites, and fry the yolks to extract oil; apply the oil for immediate effect. Method: Fry yolks until black to release the oil naturally.
Another prescription: Three qian of refined *Realgar* (Xiong Huang), one and a half qian of *Ren Zhong Bai* (Human Waste Deposit), five fen of *Qingdai* (Indigo Naturalis), three fen of borneol, all ground into fine powder. Mix with six qian of earthworm feces (thick ones preferred; one liang if wet), ground finely. Blend with urine from a healthy boy and apply several times until cured; severe cases require application for several days.
Another prescription: Grind bricks from the bottom of old cesspits into powder, mix with sesame oil for application; extremely effective.
Additionally, applying eel blood is also effective. Internal decoction required: Five fen each of *Trichosanthis Radix* (Tian Hua Fen), raw *Rhei Radix et Rhizoma* (Da Huang), and *Akebiae Caulis* (Chuan Tong Cao), decocted in water and taken orally.
Another prescription: Three qian each of *Phellodendri Cortex* (Huang Bo) and *Rhei Radix et Rhizoma* (Da Huang), one qian of *Coptidis Rhizoma* (Huang Lian), three fen of borneol, all ground into powder. Mix with bitter bile from a pig, apply to the affected area, and bind with soft silk. Also treats monkey-like chancre with miraculous effect.
Additionally, newborns with redness and赤 (redness) on hands and feet are named "Wandering Flow Fire." If it spreads from feet to lower abdomen or from hands to chest, it is often incurable; urgently use this formula. Take as much *Kalimeris Indica* (Ma Lan Tou) as needed, wash off mud, pound and squeeze juice, apply to the lesion; reapply when dry; repeatedly used with repeated efficacy. Roots can be used in winter when leaves are absent.
Another prescription: Pound large or small Chinese cabbage and apply as a poultice.
Additionally, grind carbonized shells of wild water caltrop (*Trapa natans*) into powder, mix with sesame oil, and rub; both are extremely miraculous.
