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
胃经积热而为患也，用清胃、泻黄二散，治之而消。设谓丹毒，辄用砭法及败毒之药，反促
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
，即日并安。却服金银花、甘草未而愈。
一小儿患疟，服信石之药，遍身赤痛，烦躁昏愦，用米醋一杯，徐灌而苏，良久遍身如故，
又用金银花、甘草为末，每服一钱，米醋调下，三服而安。
一小儿五岁，忽吐泻，又俄顷胸腹赤色见，遂遍身俱赤，余意其中信石之毒而然，若胎瘤食
毒，则无此急速，乃灌冷米醋一杯，吐泻即止，少刻赤渐退，半日始苏，其形尚似死。又用
羊血，接其元气而愈。

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.
