伤食发丹者，因脾胃之气未充，乳食过多，不能运化，蕴热于内，而达于肌表也。若因食乳
停滞者，先用保和丸消之，大便秘结者，量加大黄通之。乳食既消，而丹尚作者，用清中解
郁汤治之。丹邪既去，而乳食不思者，用五味异功散补之。发热作渴，或饮食少思者，用七
味白术散补之。大凡饮食浓味所致者赤晕，或行而缓慢。若饮烧酒，或误吞信石所致者，遍
身赤晕，其行甚速；又有疮疡发 ，周遭有赤晕，其热消散或脓出自退，凡此俱忌砭法，皆
宜安里为主，不可攻伐。若自吐泻，亦不可止之，吐泻中有发散之意。因饮烧酒者，饮冷米
醋一二杯解之，此神妙之法也。因母多食炙 膏粱，或饮烧酒，或服辛热燥药，或郁怒伤肝
脾，致儿为患者，当参胎热毒疮疡治之。
一小儿面赤皎白，手足常冷，伤食患丹，余谓此因脾胃虚弱，不信，另用克伐之剂，更吐泻
腹痛，吐涎不乳，口舌生疮，此脾胃复伤，而虚寒格阳在外，非实热也，先用六君、干姜，
又用五味异功散而愈。
一小儿每停食发赤晕，此脾虚食郁，用清中解郁汤而愈。越月忽摇头切牙，痰甚发搐，呕吐
酸腐，此食郁伤脾也，待其吐尽，翌日少与白术散而愈。又服前散，月余遂不复患。
一小儿停食便秘，四肢赤色，此饮食蕴毒于内，用枳实、黄连、浓朴、山楂、神曲，而便通
赤解。更头晕咳嗽，此脾气虚而不能生肺金也，用六君、桔梗，以补脾肺；山楂、神曲，以
消饮食而痊。
一小儿患此，服发表之剂，手足抽搐，服惊风之药，目 痰甚，余谓脾胃亏损，肝木所胜之
虚象，无风可祛，无痰可逐，用六君子汤一剂而安，再剂而瘥。
一小儿停食，服通利之剂，患丹作呕腹胀，此脾气复伤也，用补中益气汤、五味异功散而愈
。
一小儿因母食炙 酒面，两臂前 各漫肿一块，有根四畔，赤晕相围，余谓患处属胃经，因

其危矣。
一小儿因母饮烧酒，其子身赤如丹毒，三日间皮肤皆溃，烦躁发热，饮冷作渴，令饮冷米醋

保和丸（方见虚羸）

伤食发丹，是由于小儿脾胃之气尚未充实，乳食摄入过多，导致无法运化，体内蕴积热邪，进而外达于肌表所致。如果是因乳食停滞引起的，先用保和丸来消导积滞；若大便秘结，则酌情加入大黄以通便泄热。待乳食积滞消除后，如果丹毒仍然发作，使用清中解郁汤进行治疗。当丹毒邪气已去，但患儿仍不思饮食时，用五味异功散进行补益。若出现发热、口渴，或食欲减退的情况，使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）引起的丹毒，其红斑边缘呈红色，且蔓延速度缓慢。若是饮用烧酒，或误吞信石（砒霜类矿物药）所致，则全身布满红斑，蔓延速度极快；又有疮疡发作时，周围伴有红斑，待热退消散或脓液排出后，症状自然消退。凡此种种情况，都忌讳使用砭法（刺络放血），均应以安固里气为主，不可妄用攻伐之法。若是自发性呕吐腹泻，也不应强行止住，因为吐泻之中蕴含着发散邪气的作用。对于因饮用烧酒引起的，可饮用一两杯冷米醋来解毒，这是神妙的方法。
若因母亲多食炙烤肥甘厚味，或饮酒，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。
有一个小儿面色红白相间，手足经常发凉，因伤食患丹毒。我认为这是由于脾胃虚弱所致，但家属不信，另用了克伐（攻下消导）的药物，结果导致更严重的呕吐腹泻、腹痛，吐出涎沫且不吸吮乳汁，口舌生疮。这是脾胃再次受伤，导致虚寒格拒阳气于外，并非实热证。我先用六君子汤加干姜治疗，随后又用五味异功散调理而痊愈。
另一个小儿每次停食（消化不良）就会发红晕，这是脾虚食郁所致，我用清中解郁汤治愈。过了一个月，他突然摇头磨牙，痰多并发生抽搐，呕吐酸腐食物，这是食郁伤脾的表现。等待他将积滞吐尽后，第二天少量给予白术散调理而愈。之后继续服用前面的方剂，一个多月便不再复发。
还有一个小儿停食且便秘，四肢发红，这是饮食蕴积毒热于内所致，我使用枳实、黄连、厚朴、山楂、神曲等药，使大便通畅，红斑消退。后来出现头晕咳嗽，这是脾气虚弱不能滋生肺金（土不生金）所致，我用六君子汤加桔梗来补益脾肺；再用山楂、神曲来消食导滞，从而痊愈。
有一个小儿患此病，服用了发表（解表发汗）的药物，导致手足抽搐；服用了惊风（镇惊熄风）的药物，导致痰多加重。我认为这是脾胃亏损，被肝木所乘的虚象，没有风邪可祛，也没有痰浊可逐，于是用一剂六君子汤使其安定，再服一剂后病情好转。
还有一个小儿停食，服用了通利（泻下）的药物，患丹毒并伴有呕吐腹胀，这是脾气再次受损所致，我用补中益气汤和五味异功散治疗而痊愈。
还有一个小儿因母亲食用炙烤酒类面食，导致双臂前侧各漫肿一块，肿块有根基，四周环绕红斑。我认为患处属于胃经，是因胃经积热所致，我用清胃散和泻黄散治疗，使肿块消退。如果误认为是丹毒，随意使用砭法和败毒药物，反而会加速危重情况的发生。
还有一个小儿因母亲饮用烧酒，其子身体赤红如丹毒，三天间皮肤全部溃烂，烦躁发热，想喝冷饮。令其饮用冷米醋，当天即见安宁。随后服用金银花、甘草粉末而痊愈。
还有一个小儿患疟疾，服用了含信石的药物，导致遍身赤痛，烦躁昏愦。我用一杯米醋慢慢灌服，使其苏醒。良久之后，身体恢复常态。又用金银花、甘草研成粉末，每次服用一钱，用米醋调下，服用三次后安定。
还有一个五岁小儿，突然呕吐腹泻，片刻之间胸腹部出现红色，随即遍及全身皆赤。我推测是中了信石的毒，若是胎瘤或食毒，不会有如此急速的反应。于是灌入一杯冷米醋，吐泻立即停止，片刻后红色逐渐消退，半天后才苏醒，当时身形尚似死人。后又用羊血接续其元气，从而痊愈。

Shangshi Fadan (Erysipelas caused by food stagnation) arises because the Qi of the Spleen and Stomach is not yet robust. Excessive intake of milk and food leads to an inability to transform and transport, causing heat to accumulate internally and manifest on the muscle surface. If caused by stagnation of milk and food, first use Baohe Wan (Preserve Harmony Pill) to resolve the stagnation; if accompanied by constipation, add Rhubarb (Da Huang) in appropriate amounts to promote bowel movement. Once the food stagnation is resolved but the erysipelas persists, treat with Qingzhong Jieyu Tang (Clear Middle and Resolve Depression Decoction). After the erysipelas pathogen is eliminated but the child still lacks appetite, use Wuyi Yigong San (Five-Ingredient Powder for Enhancing Merit) to tonify. If fever and thirst occur, or there is poor appetite, use Qiwei Baizhu San (Seven-Ingredient Atractylodes Macrocephala Powder) to tonify.
Generally, erysipelas caused by rich and greasy diet presents with red halos and spreads slowly. If caused by drinking distilled spirits or accidentally ingesting Xishi (Arsenic mineral), the entire body is covered with red halos that spread very rapidly. In cases of sores and ulcers erupting with surrounding red halos, symptoms subside naturally as heat dissipates or pus discharges. All such conditions contraindicate Bianfa (Bloodletting with stone needle); the primary treatment should be to stabilize the interior, avoiding aggressive purgative methods. If spontaneous vomiting and diarrhea occur, they should not be forcibly stopped, as these processes contain a dispersive nature. For cases caused by drinking distilled spirits, drinking one or two cups of cold rice vinegar can detoxify, which is a miraculous method.
If the infant suffers due to the mother consuming excessive roasted and fatty foods, drinking alcohol, taking pungent-hot drying herbs, or suffering from emotional depression damaging the Liver and Spleen, it should be treated according to the principles for fetal heat toxic sores.
One child had a face alternating between red and pale, with cold hands and feet, suffering from erysipelas due to food stagnation. I attributed this to Spleen-Stomach deficiency. The parents did not believe me and used another purgative formula, resulting in worsened vomiting, diarrhea, abdominal pain, spitting saliva, refusal to nurse, and mouth/tongue ulcers. This indicated further injury to the Spleen-Stomach, leading to deficiency-cold repelling Yang Qi to the exterior, rather than excess heat. I first used Liujunzi Tang (Six-Gentlemen Decoction) with Dried Ginger (Gan Jiang), followed by Wuyi Yigong San, leading to recovery.
Another child developed red halos every time food stagnated, indicating Spleen deficiency with food depression. I cured him with Qingzhong Jieyu Tang. A month later, he suddenly shook his head, ground his teeth, had excessive phlegm, and suffered convulsions with vomiting of sour/rotten food. This was food depression injuring the Spleen. After waiting for him to vomit out all the stagnation, I gave a small amount of Baizhu San the next day, leading to recovery. Continued use of the previous powder prevented recurrence for over a month.
Another child had food stagnation with constipation and red limbs, indicating accumulation of toxic heat from diet inside. I used Zhi Shi (Immature Bitter Orange), Huanglian (Coptis Rhizome), Houpo (Magnolia Bark), Shanzha (Hawthorn Fruit), and Shenqu (Medicated Leaven), which resolved the constipation and redness. Later, dizziness and cough appeared, indicating Spleen Qi deficiency failing to generate Lung Metal (Earth failing to nourish Metal). I used Liujunzi Tang with Jiegeng (Platycodon Root) to tonify Spleen and Lung, and Shanzha and Shenqu to digest food, leading to cure.
One child, after taking exterior-releasing agents, suffered limb convulsions; after taking Jingfeng (Convulsion-calming) medicines, phlegm increased severely. I reasoned this was a deficiency pattern where Spleen-Stomach damage allowed Liver Wood to overact. There was no wind to dispel nor phlegm to purge. One dose of Liujunzi Tang stabilized the condition, and two doses led to improvement.
Another child, after taking purgative agents for food stagnation, developed erysipelas with vomiting and abdominal distension, indicating renewed injury to Spleen Qi. I cured him with Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) and Wuyi Yigong San.
One child, whose mother consumed roasted foods and alcohol/flour products, developed diffuse swelling on both anterior arms. Each swelling had a base surrounded by red halos. I stated the affected area belongs to the Stomach Meridian, caused by accumulated heat in the Stomach Meridian. I treated with Qingwei San (Clear the Stomach Powder) and Xiehuang San (Drain Yellow Powder), resolving the swelling. Had it been mistaken for Dan Du (Erysipelas toxin) and treated with bloodletting and detoxifying drugs, it would have accelerated the critical condition.
One child, whose mother drank distilled spirits, had a body red like erysipelas. Within three days, the skin ulcerated everywhere, with irritability, fever, and thirst for cold drinks. I administered cold rice vinegar, bringing immediate peace. Subsequently, Jin Yin Hua (Honeysuckle Flower) and Gancao (Licorice Root) powder cured him.
One child suffering from malaria took medicine containing Xishi, resulting in whole-body redness and pain, irritability, and confusion. I slowly灌 (poured/administered) one cup of rice vinegar, reviving him. After a while, his body returned to normal. Then, using Jin Yin Hua and Gancao powdered, taken one qian per dose mixed with rice vinegar, three doses brought stability.
A five-year-old child suddenly vomited and had diarrhea. Within moments, redness appeared on the chest and abdomen, spreading to the entire body. I suspected poisoning from Xishi, as fetal tumors or food toxins do not present this rapidly. I administered one cup of cold rice vinegar; vomiting and diarrhea stopped immediately. The redness gradually receded within minutes. He revived after half a day, though his form resembled death. Finally, using Sheep Blood (Yang Xue) to reconnect his Yuan Qi (Original Qi), he recovered.
