凡病中设有挟风寒者，即宜断去荤腥油腻，微服散药，俟外邪祛尽，另用滋味调补。大
抵将息痈肿，不可缺少滋味，以血肉能生血肉也。然又不宜过多，使肉气胜谷气；更忌生冷
滞气之物，恐反伤脾胃耳。并宜避风邪，戒嗔怒，寡思虑，少言语，兢兢保养为贵。至于病
后将息，毒大者，三年内宜远帷 ，毒小者，期年内宜远帷 。犯之则成虚损，或
成偏枯，或阴减天年，不可不慎也。其他戒怒慎风，亦须常作有病时想。
以上十法，乃治痈疽发背之大纲，大者可为，小者可知已。余生平喜治外症，其心法全
在于此。约而能己该，确而可守也。至于周身上下所患之病名，备载于后，以资参考。
（对心发 肾俞发 搭背 手发 足发）
生于背，名曰发背，肺经火毒也。生于背下，与心相对，名曰对心发，心经火毒也。生
于腰，名曰肾俞发，肾经相火之毒。若生于肩脊，名曰搭背，右为肺火，左为肝火也。生于
手背，名曰手发，生足背，名曰足发，脾经湿热之毒也。有如莲子形者，头多突起。有如蜂
窠形者，孔多内陷，外结螺靥。此二种，须防毒陷。大率此症，皆由膏粱浓味，或六淫外客
七情内郁所致，积聚不散，以致荣气不从，逆于肉理耳。初觉肿痛，即宜用药消散之。散
而不去，则用艾灸、提脓等法。痈疽之症，始为热中，末为寒中，不可不察也。
凡是疾病中如果兼夹风寒邪气，就应当立即停止食用荤腥油腻食物，少量服用发散药物，等到外邪完全祛除后，再另外使用滋补的食物进行调理。大抵在调养痈肿期间，不可缺少滋味（指营养丰富、易于消化的食物），因为血肉之品能够滋养人体的血肉。然而也不宜吃得过多，以免肉气的滋腻胜过谷气的运化；更忌讳食用生冷及阻碍气机运行的食物，恐怕反而损伤脾胃。并且应当避开风邪，戒除愤怒，减少思虑，少说话，以谨慎小心地保养身体为贵。至于病后的调养，毒邪严重的，三年内应当远离房事；毒邪轻微的，一年内应当远离房事。触犯这些禁忌就会形成虚损证，或者导致半身不遂，或者缩短寿命，不可不慎重。其他的如戒怒、慎避风邪等，也应当常常当作自己仍有病时那样对待。
以上十种方法，是治疗痈疽发背的大纲，重大的病症可以据此推知，微小的病症也可以由此明白。我生平喜欢治疗外科病症，其心法全在于此。简要而能涵盖全面，确切而可遵循。至于全身上下所患的各种病名，详细记载在后面，以供参考。
（对心发、肾俞发、搭背、手发、足发）
生于背部，名叫发背，属于肺经火毒。生于背部下方，与心脏相对，名叫对心发，属于心经火毒。生于腰部，名叫肾俞发，属于肾经相火之毒。如果生于肩脊部位，名叫搭背，右侧属于肺火，左侧属于肝火。生于手背，名叫手发，生于足背，名叫足发，属于脾经湿热之毒。有的像莲子形状，头部多突起；有的像蜂巢形状，孔洞多内陷，外部结成螺靥（一种疮疡形态）。这两种情况，必须防止毒邪内陷。大率这种病症，都是由膏粱厚味（肥甘厚味），或六淫外感、七情内郁所致，积聚不散，导致营气不顺，逆乱于肌肉纹理之间。初起感觉肿痛，就应当用药消散。消散不去，则用艾灸、提脓等方法。痈疽这类病症，初期多为热证，末期多为寒证，不可不仔细辨别。
In any disease where wind-cold pathogens are involved, one should immediately abstain from meat, fish, and greasy foods, take small doses of diaphoretic (sweat-inducing) medicines, and wait until the external pathogens are completely expelled before using nourishing foods for tonification. Generally speaking, in the convalescence of carbuncles and swellings, it is indispensable to consume nutritious foods, as animal products can generate human flesh and blood. However, one should not overeat, lest the cloying nature of meat overpower the transforming power of grains; more importantly, one must avoid raw, cold, and qi-stagnating foods, fearing they may damage the Spleen and Stomach. One should also avoid wind pathogens, refrain from anger, reduce excessive thinking, speak little, and prioritize careful preservation of health. Regarding post-illness care, for severe toxicity, sexual abstinence is recommended for three years; for mild toxicity, for one year. Violating these rules leads to deficiency syndromes, hemiplegia, or a shortened lifespan, so caution is essential. Other precautions such as refraining from anger and avoiding wind should be treated with the same seriousness as when one is still ill.
The above ten methods constitute the general principles for treating carbuncles and back-sores. Major cases can be understood through them, and minor cases can be inferred. Throughout my life, I have favored treating external diseases, and my core methodology lies herein. It is concise yet comprehensive, accurate, and practicable. The names of various diseases affecting the entire body are detailed below for reference.
(Duixin Fa, Shenshu Fa, Dabe, Shoufa, Zu Fa)
A sore occurring on the back is named "Fabei" (Back Carbuncle), caused by Fire-Toxin in the Lung Meridian. A sore occurring on the lower back, opposite the heart, is named "Duixin Fa" (Opposite-Heart Carbuncle), caused by Fire-Toxin in the Heart Meridian. A sore occurring on the waist is named "Shenshu Fa" (Shenshu Carbuncle), caused by Ministerial Fire-Toxin in the Kidney Meridian. If it occurs on the shoulder and spine, it is named "Dabe" (Shoulder-Back Carbuncle); right-sided cases are due to Lung Fire, while left-sided cases are due to Liver Fire. A sore on the dorsum of the hand is named "Shoufa" (Hand Carbuncle), and one on the dorsum of the foot is named "Zufa" (Foot Carbuncle), both caused by Damp-Heat-Toxin in the Spleen Meridian. Some resemble lotus seeds, with multiple protruding heads; others resemble honeycombs, with multiple depressed pores and external crust formation resembling snail shells. In these two types, one must guard against toxin sinking inward. Generally, this condition arises from rich and fatty diets, or from the invasion of Six Exogenous Pathogens and internal stagnation of Seven Emotions, leading to accumulation that fails to disperse, causing Ying-Qi (Nutritive Qi) to become disordered and逆流逆乱 (reverse flow/disorder) within the muscle tissue. Upon initial swelling and pain, medication should be used to dissipate the condition. If dissipation fails, moxibustion and pus-draining methods should be employed. Carbuncles and ulcers initially present as Heat syndromes but often transform into Cold syndromes in their late stages; this distinction must not be overlooked.
