仲阳云∶热毒之气，客于腠理，搏于血气，发于外皮，上赤如丹，热毒与血相击，而风气乘之，所以赤肿游走而遍
体也。此由乳母食酒面煎炙过度，与夫烘衣与儿，不候冷而即穿者，多成此症。或发于头面胸背，令儿燥闷腹胀，如火
之热，痛不可言。有入腹、入肾之证，便不可救。又方，小儿一周之内，皮毛肌肉，筋骨髓脑，五脏六腑，荣卫血气，
皆未坚固，譬如草木萌芽之状，未经寒暑，娇嫩软弱，今婴孩称为芽儿故也；一周之内，切不可频频洗浴，恐湿热之
气，郁蒸不散，遍身生赤游丹毒，俗为之溜，片片如胭脂涂染，皆肿而壮热，若毒入腹者，则腹胀硬气，以致杀儿，此
因洗浴而得也。若肌肉宽缓，腠理开泄，包裹失宜，复为风邪所乘，而身生白溜，皆肿而壮热也，或憎寒壮热，鼻塞脑
闷，或上气痰喘，咳嗽吐逆，种种之疾，皆因洗浴脱着而得也。治赤溜丹毒，可用小刀子疏去溜头赤晕恶血毒汁，次以
冰黄散、葛根白术散、惺芎散主之。败毒散及升麻汤、防己散皆可选而用之。又丹热、实热、龙带热，并用大连翘汤加
大黄及灯心煎服殊验。

钱乙（字仲阳）说：热毒之气，侵袭腠理（皮肤与肌肉之间的间隙），与血气相互搏结，发作于体表皮肤。患处颜色红赤如丹砂，热毒与血液相击，加之风邪趁虚而入，所以出现红肿胀痛、游走不定并遍布全身的症状。这通常是因为乳母过度食用酒、面食及煎炸烤炙的食物，或者用火烘烤衣物给孩子穿，且不待冷却就立即给孩子穿上所致，很容易形成这种病症。症状可能出现在头面、胸背部位，导致孩子烦躁闷乱、腹胀，体内热气如火烧一般，疼痛难以言表。如果毒邪深入腹部或肾脏，则病情危重，不可救治。
另一种情况是，婴儿出生一周之内，其皮毛、肌肉、筋脉、骨髓、脑髓以及五脏六腑、营卫气血都尚未坚固，就像草木刚发出的嫩芽一样，未经过寒暑的考验，娇嫩软弱，所以婴儿被称为“芽儿”。在这一周内，切不可频繁给婴儿洗浴，恐怕湿热之气郁积蒸腾不散，导致遍身生出赤游丹毒，俗称“溜”，皮损片片状如胭脂涂抹，红肿且高热。如果毒邪入腹，会导致腹胀坚硬、气机阻滞，甚至导致婴儿死亡，这是因洗浴不当而引发的疾病。如果肌肉松弛，腠理开泄，包裹护理不当，又受到风邪侵袭，身体就会生出白溜，同样表现为红肿和高热；或者出现怕冷高热、鼻塞头脑昏闷，或气逆痰喘、咳嗽呕吐等症状，种种疾病，都是因为洗浴后穿衣脱衣不当（受凉或受热）而导致的。
治疗赤溜丹毒，可用小刀轻轻刺破瘤头处的红晕，排出恶血和毒汁，然后使用冰黄散、葛根白术散、惺芎散为主进行治疗。败毒散、升麻汤、防己散也可以酌情选用。另外，对于丹热、实热、龙带热（一种小儿热病），均可使用大连翘汤加入大黄及灯心草煎服，效果显著。

Qian Yi (courtesy name Zhongyang) stated: The pathogenic factor of heat-toxin invades the *coulī* (the interstitial spaces between skin and muscle), contends with the blood and qi, and manifests on the external skin. The affected area appears red like cinnabar. When heat-toxin contends with blood, and wind-pathogen takes advantage of this deficiency, it results in redness, swelling, pain, and a migratory nature that spreads throughout the body. This condition often arises from the wet nurse consuming excessive amounts of alcohol, wheat products, and fried or roasted foods, or from drying clothes with fire and dressing the infant before they have cooled down. Symptoms may appear on the head, face, chest, and back, causing the infant to feel irritable, stifled, and bloated, with internal heat resembling burning fire and unbearable pain. If the toxin penetrates into the abdomen or kidneys, the condition becomes incurable.
Alternatively, within the first week after birth, an infant's skin, muscles, sinews, bones, marrow, brain, five zang organs, six fu organs, *ying* (nutritive) and *wei* (defensive) qi, and blood and qi are not yet solidified. They are like the sprouts of grass and trees, untested by cold and heat, tender and weak; hence infants are called "sprout children." During this week, frequent bathing should be strictly avoided. Otherwise, damp-heat may stagnate and vaporize without dispersing, leading to *chiyou dandu* (migratory erysipelas) covering the whole body. Commonly known as "liu," these lesions resemble smears of rouge, presenting with swelling and high fever. If the toxin enters the abdomen, it causes abdominal distension, hardness, and qi obstruction, potentially leading to death. This is caused by improper bathing practices. If the muscles are lax and the *coulī* open, and if wrapping and care are inappropriate, allowing wind-pathogen to invade, *bai liu* (white migratory erysipelas) may appear on the body, also characterized by swelling and high fever. Other symptoms may include aversion to cold with high fever, nasal congestion and mental fogginess, upward rushing of qi with phlegm and wheezing, coughing, and vomiting. All these ailments result from exposure to temperature changes during bathing and dressing.
To treat *chi liu dandu*, one may use a small knife to gently puncture the red halo at the head of the lesion to drain evil blood and toxic fluid. Subsequently, *Binghuang San* (Ice and Yellow Powder), *Gegen Baizhu San* (Pueraria and Atractylodes Macrocephala Powder), or *Xingxiong San* (Awakening and Asarum Powder) should be administered as primary treatments. *Baidou San* (Defeat Toxin Powder), *Shengma Tang* (Cimicifuga Decoction), and *Fangji San* (Stephania Tetrandra Powder) are also optional choices. Furthermore, for conditions such as *dan re* (erysipelas heat), *shi re* (excess heat), and *long dai re* (dragon belt heat), *Dalianqiao Tang* (Large Forsythia Decoction) added with *Dahuang* (Rhubarb Rhizome) and *Dengxincao* (Juncus Effusus) should be decocted and taken orally, showing remarkable efficacy.
