（一名赤游风）
小儿头面、背腹、手足或有红点者，乃丹毒之候。红晕蔓延最疾者，火丹也。红晕上生赤肿，或如粟米，或如瘾
疹，或如癣疥，蔓延差缓者，风丹也（治同）。随赤色晕处，以三棱针乱刺出毒血，一日二、三次（弃血如粪）。五
福化毒丹，犀角消毒饮（二方并见下）并主之。
一方∶白清涂楸叶（叶干则浸水用之）频敷之，善消红色。
一方∶芥子烂捣作饼，敷红晕边，则毒瓦斯不得外肆蔓延。
一方∶生栗留内皮磨于父溺，涂之。
一方∶豆腐炙于火上敷之。
一方∶下针后生猪肉作片敷之。又生狗皮乘温敷之。
小儿胎疮脓破后，不即完合，疮边有赤色者，多发火丹，治法上同。
小儿面部猝浮，色白如常，渐为蔓延成疮，如癣疥者，亦丹毒之类，俗名曰白丹毒，治法上同。
（小儿之病，最多腹痛）
一、二岁儿未语者，有腹痛则必悲啼汗出，转身亘腹，坐卧不定，频顾下腹，时止时作者，热腹痛也。导赤散（方
见下）加软芩五分服之。
小儿未着裤之前，善脱覆绷，腹部犯风或触冷，则外寒逼身，亦发腹痛，服参茶四、五分。如无人参，则茴香（酒
炒）、乳香、香附子等分煎服。
小儿或处冷 ，或处湿地，腹痛吐乳，或噫甚，治法上同。
小儿夜啼有四∶一曰寒，二曰热，三曰口疮、重舌，四曰客忤也。下夜半曲腰而啼，口有冷气者，寒腹痛，六神散
（方见下）主之。上夜半仰身而啼，有汗身热者，热腹痛，导赤散主之。口到乳上不能吮，而即啼者，口疮（鸡卵四、
五个，和白清服之，立效）、重舌（以针乱刺两边出血，勿犯中缝。一方，蒲黄炒，和白清频涂，最妙）。犯客忤或触
外人气忤而啼，黄昏时尤甚者，乃容忤中恶也，苏合丸主之。
小儿吮乳后即发腹痛者，盖以乳母多胃热故也。乳母宜服石膏平胃散（方见下）。乳母过食油腻生冷之物，则儿亦
发腹痛、吐乳、泄痢，乳母于平胃散加肉桂、干姜、枳壳、黄柏各五大分服之，腹痛立愈。
小儿环脐痛不可忍，名曰盘肠内吊，乳香散（方见下）主之。
（又名赤游风）
小儿的头面、背部、腹部、手和足如果出现红点，这是丹毒的症状。红晕蔓延速度最快的，称为火丹。红晕上出现红肿，或者像粟米大小，或者像瘾疹，或者像癣疥，蔓延速度较慢的，称为风丹（治疗方法相同）。在红色晕染的部位，用三棱针乱刺放出毒血，一天两到三次（排出的血液像粪便一样多）。五福化毒丹、犀角消毒饮（这两个方剂均见下文）都可以主治。
一方：将白清涂抹在楸叶上（叶子干枯则用水浸泡后使用），频繁敷贴，能很好地消除红色。
一方：将芥子捣烂做成饼，敷在红晕的边缘，这样毒气就不能向外肆意蔓延。
一方：在下针后，用生猪肉切片敷贴。或者趁温热时用生狗皮敷贴。
小儿胎疮脓液破溃后，不能立即愈合，疮口边缘有红色的，容易并发火丹，治疗方法同上。
小儿面部突然浮肿，颜色像平常一样白，逐渐蔓延形成疮疡，像癣疥一样的，也属于丹毒一类，俗称白丹毒，治疗方法同上。
（小儿的疾病中，腹痛最为多见）
一、二岁还不会说话的孩子，如果腹痛一定会悲伤啼哭并出汗，转身拱腹，坐卧不安，频繁查看下腹部，疼痛时好时坏，这是热性腹痛。服用导赤散（方剂见下文），加入软黄芩五分煎服。
小儿在穿裤子之前，喜欢脱掉包裹的布带，腹部受风或接触冷物，导致外寒侵袭身体，也会引发腹痛，服用参茶四到五分。如果没有人参，则用茴香（酒炒）、乳香、香附子等量煎服。
小儿如果处于寒冷环境，或者处于潮湿之地，出现腹痛吐奶，或者嗳气严重，治疗方法同上。
小儿夜啼有四种原因：一是寒，二是热，三是口疮、重舌，四是客忤。下半夜弯腰啼哭，口中呼出冷气的是寒性腹痛，由六神散（方剂见下文）主治。上半夜仰身啼哭，有汗且身体发热的是热性腹痛，由导赤散主治。嘴巴碰到乳头无法吮吸就啼哭的，是口疮（用四个五个鸡蛋清，混合白清服用，立刻见效）、重舌（用针在两边乱刺出血，不要刺中间缝隙。另一方，蒲黄炒过后，混合白清频繁涂抹，效果最好）。受到客忤或触碰到外人的邪气而啼哭，黄昏时分特别严重的，是容忤中恶，由苏合丸主治。
小儿吃奶后立即发生腹痛，大概是因为乳母胃中有热的缘故。乳母宜服用石膏平胃散（方剂见下文）。乳母如果过食油腻生冷食物，孩子也会发生腹痛、吐奶、腹泻痢疾，乳母应在平胃散中加入肉桂、干姜、枳壳、黄柏各五大分服用，腹痛立刻痊愈。
(Also known as Chi You Feng [Red Roaming Wind])
If red spots appear on the head, face, back, abdomen, hands, and feet of infants and children, this is a manifestation of Dan Du [Erysipelas]. When the red halo spreads most rapidly, it is called Huo Dan [Fire Erysipelas]. When the red halo presents with redness and swelling, resembling millet grains, or like urticaria (wind wheals), or like tinea and scabies, and spreads more slowly, it is called Feng Dan [Wind Erysipelas] (the treatment is the same). At the area of the red halo, prick randomly with a three-edged needle to release toxic blood, two to three times a day (the discharged blood resembles feces). Wu Fu Hua Du Wan (Five Blessings Detoxifying Pill) and Xi Jiao Xiao Du Yin (Rhinoceros Horn Detoxification Decoction) (both formulas are listed below) are indicated.
One prescription: Apply Bai Qing [White Egg White] onto Qiuye [Ficus tikoua Bur. leaves] (if the leaves are dry, soak them in water before use) and apply frequently; this effectively eliminates redness.
One prescription: Pound Mustard Seeds (Jiezi) into a paste to form a cake, and apply it to the edge of the red halo, so that toxic qi cannot spread outward recklessly.
One prescription: Take raw chestnuts retaining their inner skin, grind them, mix with the father's urine, and apply topically.
One prescription: Roast tofu over fire and apply topically while warm.
One prescription: After needling, apply slices of raw pork topically. Alternatively, apply raw dog skin while it is still warm.
After the pus from infantile eczema (Tai Chuang) ruptures, if the wound does not heal immediately and the edges become red, it often develops into Huo Dan [Fire Erysipelas]; the treatment method is the same as above.
If an infant's face suddenly swells, appearing white as usual, which gradually spreads to form sores resembling tinea or scabies, this also belongs to the category of Dan Du [Erysipelas], commonly known as Bai Dan Du [White Erysipelas]; the treatment method is the same as above.
(Among diseases of infants and children, abdominal pain is the most common.)
For one- or two-year-old children who have not yet learned to speak, if they experience abdominal pain, they will inevitably cry sadly, sweat, turn around and arch their bellies, be restless sitting or lying down, frequently look at the lower abdomen, and have intermittent pain. This is Re Xing Fu Tong [Heat-type Abdominal Pain]. Administer Dao Chi San (Formula listed below) with Ruan Huang Qin [Scutellariae Radix Softened] (5 fen) added, decocted and taken orally.
Before infants start wearing trousers, if they tend to remove their swaddling clothes, and their abdomen is exposed to wind or cold contact, causing external cold to invade the body, abdominal pain may occur. Administer Shen Cha [Ginseng Tea] (4-5 fen). If Ginseng (Renshen) is unavailable, then equal parts of Fennel (Huixiang, wine-fried), Frankincense (Ruxiang), and Cyperi Rhizome (Xiangfuzi) should be decocted and taken orally.
If infants are placed in cold environments or damp places, resulting in abdominal pain, vomiting of milk, or severe belching, the treatment method is the same as above.
There are four causes for nocturnal crying in infants: one is Cold, two is Heat, three is Kou Chuang [Mouth Ulcers] and Chong She [Double Tongue], and four is Ke Wu [External Evil Intrusion]. Crying while bending the waist in the latter half of the night, with cold breath from the mouth, indicates Han Xing Fu Tong [Cold-type Abdominal Pain], treated by Liu Shen San (Formula listed below). Crying while lying on the back in the first half of the night, with sweating and fever, indicates Re Xing Fu Tong [Heat-type Abdominal Pain], treated by Dao Chi San. Crying immediately upon touching the nipple without being able to suckle indicates Kou Chuang [Mouth Ulcers] (take 4-5 egg whites mixed with Bai Qing [White Egg White] orally for immediate effect) or Chong She [Double Tongue] (prick both sides randomly with a needle until bleeding occurs, avoiding the midline suture; alternatively, stir-fried Puhuang [Lygodii Spora] mixed with Bai Qing [White Egg White] applied frequently is best). Crying due to Ke Wu [External Evil Intrusion] or exposure to external evil qi, especially severe at dusk, indicates Rong Wu Zhong E [Invasion of Malevolent Qi], treated by Su He Wan (Styrax Pill).
If abdominal pain occurs immediately after an infant suckles milk, it is likely due to the mother having Stomach Heat. The nursing mother should take Shi Gao Ping Wei San (Gypsum Pingwei Powder) (Formula listed below). If the nursing mother consumes excessive greasy, cold, or raw foods, the infant may develop abdominal pain, vomiting of milk, and dysentery. The nursing mother should add Rou Gui [Cinnamon Bark], Gan Jiang [Zingiberis Rhizoma], Zhi Qiao [Aurantii Fructus], and Huang Bo [Phellodendri Cortex] (each 5 da fen) to Ping Wei San and take it orally; the abdominal pain will resolve immediately.
Severe pain around the umbilicus that is unbearable is named Pan Chang Nei Diao [Coiled Intestine Internal Torsion], treated by Ru Xiang San (Frankincense Powder) (Formula listed below).
