伤食引起的丹毒，是因为小儿脾胃之气尚未充实，乳食摄入过多，无法运化，导致热邪蕴结于体内并外达肌表。
如果是因乳食停滞引起的，先用保和丸来消导积滞；如果大便秘结，酌情加入大黄以通泄大便。待乳食积滞消除后，如果丹毒仍然发作，用清中解郁汤治疗。当丹毒邪气已去，但小儿仍不思饮食时，用五味异功散进行补益。如果出现发热、口渴，或者食欲减退的情况，用七味白术散进行补益。一般来说，由饮食厚味（油腻辛辣食物）引起的，赤色晕圈蔓延缓慢。如果是饮用烧酒，或误吞信石（砒霜）引起的，遍身出现赤色晕圈，蔓延速度非常快。又有疮疡发作时，周围有赤色晕圈，待热势消散，或脓液流出后自然消退，凡此情况都忌用砭法（刺破放血），都应以安固里气为主，不可使用攻伐之法。如果是自发的呕吐腹泻，也不可用止泻止吐药强行制止，因为吐泻之中蕴含着发散邪气的机理。对于因饮用烧酒引起的，可饮用冷米醋一二杯来解毒，这是神妙的方法。
如果是由于母亲多吃烧烤、肥甘厚味，或饮用烧酒，或服用辛热燥烈药物，或因郁怒损伤肝脾，从而导致婴儿患病的，应当参照胎热毒疮疡的方法来治疗。
〔曾氏〕婴儿出生后百日之内，或半岁以上，突然两眼眼睑红晕微起，面色呈现青黯色，入夜烦躁啼哭，或者脸部像胭脂一样红，这是伏热在内。也有脸部不红的，起初是因为在母体受孕时，母亲受到重大惊吓，惊邪伤及胎儿，代代相传袭，表现于外，初发时散布满脸，形状像水痘，脚部微红但不壮实，出没无常，随后蔓延到颈项，红得像朱砂，称为惊丹。先用四圣散清洗眼部，再用百解散加五和汤同煎，用以解除惊热丹毒。牛蒡汤、当归散、三解散、黄芩四物汤，都可以用来治疗。如果惊丹发展到胸乳之间，伴有轻微的痰喘和抽搐，应立即宣散热毒、拔除毒素，以免邪气内流，造成严重危害。用五和汤加升麻、生干地黄、生姜、灯心草煎服，则能自行消除，之后仍用前述几种药物调理，以防产生其他病变。或者投用万安饮。

将药材切碎。每次服用，用水一盏，煎至七分，不拘时候，温服。
四圣散（用于初生儿眼睛不开）、石解散（用于惊风）、五和汤（用于发热）、牛蒡汤（用于咽喉病）、当归散、三解散（均用于发热）。
Danthu (carbuncle-like rash) caused by food stagnation occurs because the Qi of the Spleen and Stomach is not yet sufficient. Excessive intake of milk and food cannot be transformed and transported, leading to heat accumulation internally that reaches the muscle surface.
If caused by food stagnation, first use Baohe Wan (Preserve Harmony Pill) to dissipate it; if there is constipation, add Rhubarb (Da Huang) in appropriate amounts to unblock the bowels. Once the food stagnation has been resolved but the Danthu persists, treat with Qingzhong Jieyu Tang (Clear the Middle and Resolve Depression Decoction). After the Danthu pathogen is eliminated but the infant still lacks appetite, tonify with Wuyi Yigong San (Five-Ingredient Powder for Extraordinary Merit). If there is fever with thirst, or reduced desire for food, tonify with Qiwei Baizhu San (Seven-Ingredient Powder for White Atractylodes). Generally, those caused by rich and greasy foods present with a red halo spreading slowly. Those caused by drinking distilled spirits or accidentally ingesting arsenic trioxide (Xinshi) present with a red halo all over the body, spreading very rapidly. Additionally, when sores and ulcers erupt, they are surrounded by a red halo; when the heat dissipates or pus discharges, they subside naturally. All such cases contraindicate Bianfa (scarification therapy), and treatment should primarily focus on stabilizing the interior rather than using attacking methods. If spontaneous vomiting and diarrhea occur, do not forcibly stop them, as vomiting and diarrhea contain the mechanism of dispersing pathogens. For cases caused by drinking distilled spirits, drink one or two cups of cold rice vinegar to detoxify, which is a miraculous method.
If the infant suffers due to the mother consuming excessive roasted, fried, or rich foods, drinking distilled spirits, taking pungent-hot dry drugs, or suffering Liver-Spleen injury from depression and anger, treat according to the principles for fetal heat toxic sores.
[Zeng's experience] Within one hundred days after birth, or after half a year, an infant suddenly presents with slightly raised red halos on both eyelids, a cyan-dark facial complexion, nighttime irritability and crying, or a face red like rouge, indicating latent heat within. There are also cases where the face is not red; initially, this is because during gestation, the mother suffered severe fright, causing fright pathogen to injure the fetus, transmitting sequentially, manifesting externally. Initially, it scatters across the whole face, resembling water blisters, with slightly red but not prominent bases, appearing and disappearing irregularly, then spreading to the neck, red like cinnabar, named Jingdan (Fright Danthu). First wash the eyes with Sixian San (Four Holy Powders); then decoct Baixie San (Hundred Resolving Powder) together with Wuhe Tang (Five Harmonizing Decoction) to resolve fright heat, Danthu, and toxicity. Niubang Tang (Arctium Decoction), Danggui San (Angelica Powder), Sansjie San (Three Resolving Powders), and Huangqin Siwu Tang (Scutellaria Four Substances Decoction) can all be used for treatment. If Jingdan spreads to the chest and breast area, accompanied by slight phlegm-wheeze and convulsions, urgently scatter heat and extract toxins to prevent internal flow, which would cause significant harm. Decoct Wuhe Tang with Shengma (Cimicifugae Rhizoma), Sheng Gan Dihuang (Rehmanniae Radix Recens), Shengjiang (Zingiberis Rhizoma Recens), and Dengxincao (Junci Medulla) to take warm, which will resolve spontaneously; subsequently regulate with the aforementioned medicines to prevent other complications. Alternatively, administer Wan'an Yin (Ten Thousand Peace Drink).
Huangqin Siwu Tang: Treats various sores, Danthu, red tumors, and dry itching.
Scutellariae Radix (Huangqin, 1 liang), Angelicae Sinensis Radix (Danggui, wine-washed), Rehmanniae Radix Recens (Sheng Gan Dihuang), Paeoniae Radix Rubra (Chishao), Chuanxiong Rhizoma (Chuanxiong) [each of these four is 0.5 liang], Polygoni Multiflori Caulis (Heshouwu, remove coarse skin), Aconiti Lateralis Radix Preparata (Caowu, processed, remove skin), Scrophulariae Radix (Xuanshen) [each of these three is 2.5 qian], Glycyrrhizae Radix et Rhizoma (Gancao, 6 qian), Menthae Haplocalycis Herba (Bohe, 2 qian).
Coarsely crush the herbs. For each dose, use one cup of water, decoct to seven-tenths, take warm at any time.
Sixian San (for newborns whose eyes do not open), Shijie San (for fright), Wuhe Tang (for fever), Niubang Tang (for throat conditions), Danggui San, Sansjie San (all for fever).
