一痈与疽之治，截然两途，世人以痈疽连呼并治。夫痈疽二字之连呼，即夫妻二字之连
呼也。若以痈药治疽，犹以安胎之药治其夫矣。是集以痈、疽分别两治，皆执症执方之治法
，如照法法制，照症用药，救人之功，余不敢分，害人之罪，余当独认，情愿万劫披毛，甘
受屠家诛戮。
一辑是集，专论阴虚阳实，认定红白两色，是痈是疽，治即全愈，所载诸方，皆药到病
愈，切勿增减，并贵重之物少。分逐症治法，开卷一目了然，不必投师，人人可精此道。
一诸书惟《冯氏锦囊》内附《阴疽论》，与余家《遗秘》相符，独无消疽之方，惟以温
补兼托为法，且疽初起，即如平塌，安可用托？托则成功。余家之治，以消为贵，以托为畏
，即流注、瘰 、恶核，倘有溃者，仍不敢托，托则溃者虽敛，增出者又何如耶？故以消为
贵也。
一外科之虚实，发现下患，治患之法，集中详细，不谙脉息，尽可救人，故痘症之险闷
顺逆，眼科之心肝脾肺肾，皆现于外，故亦不诊脉也。好学人察患色则知症，照症治无不痊
一医可寄生死，阅坊刻外科，妄称正宗，载云∶症现七恶即死。又载∶以桐油烧红衣针
针入痰块半寸，用降药为条，插入针孔，七日块自开裂，再以条插七日，其核自落。又称，
毒在皮里肉内，刀割深要寸许，方能泄毒。殊不知毒在皮里膜外，或应开刀，尚忌深过三分
，恐伤内膜，若深入寸许，伤透内腑，病患何能堪极刑？七恶之现顷刻，世之宗其法治，尽
属刽徒。此集惟疔用刺，其外概不轻用刀针，并禁升、降、痛烂三药。
一遍身患只有红白两色，红者痈，白者疽，痈疽即其名也。有谓∶无名肿毒，因未识症
而云。
一是书无论背项腰腹，色白者言疽，以疽药愈之；红肿者言痈，以痈药愈之。坊刻书称
∶以某药与服，不应再易某药。岂非以人试药乎。倘患生要紧穴道，安可遭医试，望高明详
之！
一世无烂久之痈，惟疽初起失消，或遭降、灸、针、割，以致年久不敛，治之方药，集
中细详。
一此集流到之处，好学人自然以初起者消，溃者敛。余恐迟到处，医未经目，人未习见
，是以坊翻刻，速遍海内，使医有生人之治，而患无枉死之人，遂余愿矣！
一载痈疽、咽喉、疔毒、结毒、诸疮、痔漏等症，皆药到病愈之方。另有杂症五十方，
专愈五十病，一服即效者，附梓集中，内无以人试药之误。望有力者照方合就，遇病施送，
或只取药本。如抄方传人，注明法制。
一是书所有之药，悉登末卷，法制处不可忽略，宜细心照法精制，药纯效速。
一伤寒症有转经传变，故有医不执方之说，至如外科杂症，全赖识症执方。余年七十有
二，治病经历四十余年，用药从无一错，故敢辑是集，以公诸世，因名《症治全生》。
关于痈与疽的治疗，两者截然不同，世人习惯将“痈疽”连称并统一治疗。其实，“痈疽”二字连用，就像“夫妻”二字连用一样（意指二者性质不同却常被混为一谈）。如果用治痈的药去治疽，就如同用安胎的药去治丈夫（比喻药不对症，南辕北辙）。本集对痈和疽分别进行针对性治疗，都遵循依据症状、依据方剂的治疗原则。如果按照方法操作，根据症状用药，救人有功，我不敢居功；若害人有过，我愿独自承担，哪怕万劫不复、甘愿受屠宰般的诛戮也在所不惜。
编辑本集，专门论述阴虚阳实的病机，认定红、白两种颜色来区分是痈还是疽，只要辨证准确，疾病即可痊愈。书中记载的各方剂，都是药到病除的良方，切勿随意增减药味，且所用药物多为寻常之物，并不贵重。本书按症状分列治法，翻开书卷便一目了然，不必拜师求学，人人都能精通此道。
各类医书中，只有《冯氏锦囊》内附带的《阴疽论》，与我家的《遗秘》相符，但唯独缺少消除疽毒的方子，仅以温补兼托毒外出为法则。况且疽初起时，疮面往往平塌，怎么能使用托法？一旦使用托法，反而会导致病情恶化或难以收口。我家治疗的原则是以“消”（消散）为贵，以“托”（托毒）为畏。即使是流注、瘰疬、恶核等病症，如果有已经溃破的，依然不敢轻易使用托法，因为托法会使已溃者虽然暂时收敛，但新产生的病灶又会如何呢？所以强调以“消”为贵。
外科疾病的虚实表现于患处，治疗患处的方法在集中已有详细说明。即使不精通脉诊，也完全可以救人。因此，痘疹病症的险闷顺逆，眼科中心、肝、脾、肺、肾的病变，都会反映在外部，所以也不需要诊脉。好学之人通过观察患处的颜色就能知道病症，依据症状治疗没有不痊愈的。
医生可以决定病人的生死。阅读市面上刻印的外科书籍，妄称自己是正宗传承，书中记载：出现“七恶”症状即刻死亡。又记载：用桐油烧红的红衣针针刺入痰块半寸深，用降药制成条状插入针孔，七天后面块自然开裂，再插七天，硬结自然脱落。还声称，毒邪在皮里肉内，必须用刀割开一寸多深，才能泄出毒邪。殊不知毒邪多在皮里膜外，即便需要开刀，也忌讳深度超过三分，恐怕损伤内膜。如果深入一寸左右，伤透内脏，病人怎能承受这种酷刑？“七恶”的出现往往在顷刻之间，世间那些遵循这些法治病的人，简直都是刽子手。本集除了疔疮使用刺法外，其余一概不轻易使用刀针，并禁止使用升药、降药以及导致腐烂的药物。
遍观全身患处，只有红、白两种颜色。红色的是痈，白色的是疽，痈和疽就是它们的名称。有人说是“无名肿毒”，是因为不认识病症才这么叫的。
这本书不论患处是在背部、颈部、腰部还是腹部，颜色发白的称为疽，用治疽的药治愈；红肿的称为痈，用治痈的药治愈。坊间刻印的书声称：先用某药服用，无效再换另一药。这难道不是拿人当试药的试验品吗？如果患处生在要害穴位，怎么可以让医生来试探？希望高明之士仔细斟酌！
世上没有久治不愈的痈，只有因疽初起时未能及时消散，或者遭到降药、灸法、针刺、切割等误治，导致多年不愈合的情况。对此的治疗方药，集中已有详细记载。
本集流传到的地方，好学之人自然会做到初起即消散，溃破即收敛。我担心它到达较晚的地方，医生未曾见过，人们也未习见，所以翻刻发行，迅速遍布海内，使医生能有救人的医术，而患者没有枉死之人，这就实现了我的愿望！
书中记载了痈疽、咽喉、疔毒、结毒、各种疮疡、痔漏等病症，都是药到病除的方子。另有杂症五十方，专门治愈五十种疾病，一服即见效，附录在集中刊印，里面没有拿人试药的错误。希望有能力的人按照方子配好药，遇到病患施舍赠送，或者只收取药费成本。如果是抄录方子传授他人，请注明具体的炮制和使用方法。
本书所用的所有药物，全部登载在卷末，炮制方法处不可忽略，应当细心按照方法精制，这样药性纯正，疗效迅速。
伤寒病症有传经变证，所以有医生不固执守方的说法。至于外科杂症，完全依赖识别症状并坚守方剂。我今年七十二岁，治病经历四十余年，用药从未出过错，所以敢编辑本集，公之于世，因此命名为《症治全生》。
Regarding the treatment of carbuncle (Yong) and gangrene (Ju), the two approaches are completely distinct. The general public tends to refer to them together as "carbuncle-gangrene" and treat them uniformly. The conjunction of the terms "carbuncle" and "gangrene" is akin to the conjunction of "husband" and "wife"—they are often mentioned together but represent different entities. To use medicine for carbuncle to treat gangrene is like using fetal-calming medicine to treat a husband (a metaphor for inappropriate treatment). This collection treats carbuncles and gangrenes separately, adhering strictly to symptom-based and formula-based methods. If one follows these methods precisely and prescribes according to symptoms, any merit in saving lives shall not be claimed by me; however, if harm is caused, I alone will bear the guilt, even if it means eternal damnation or suffering execution like livestock.
This compilation focuses specifically on the pathogenesis of Yin deficiency and Yang excess, identifying red and white colors to distinguish between carbuncles and gangrenes. With accurate differentiation, recovery is assured. All formulas recorded herein are effective immediately upon administration; they should not be arbitrarily modified, and the ingredients used are common and inexpensive. Treatment methods are categorized by symptoms, allowing readers to understand them at a glance without needing formal apprenticeship, enabling anyone to master this discipline.
Among various medical texts, only the *Treatise on Yin Gangrene* (*Yin Ju Lun*) appended to *Feng Shi Jin Nang* aligns with my family's secret records (*Yi Mi*). However, it lacks formulas for resolving gangrene, relying solely on warming tonification combined with expelling toxins. Moreover, early-stage gangrene often presents as flat lesions; how can expulsion methods be applied? Using expulsion may lead to complications. My family’s principle prioritizes "resolution" (Xiao) over "expulsion" (Tuo). Even for conditions such as flowing abscesses (Liuzhu), scrofula (Luoli), and malignant nodules (Ehe), if ulceration has occurred, we dare not use expulsion, as it might cause healed ulcers to reopen while new ones emerge. Hence, resolution is paramount.
The deficiency and excess patterns of surgical diseases manifest in the affected areas, and detailed treatment methods are provided in this collection. One can save lives even without proficiency in pulse diagnosis. Therefore, for severe cases of smallpox (or chickenpox/variolous diseases) showing danger or smooth progression, and for eye diseases reflecting disorders of the Heart, Liver, Spleen, Lung, and Kidney, external signs suffice, making pulse diagnosis unnecessary. Diligent students can identify symptoms by observing lesion colors and achieve cure through symptomatic treatment.
Physicians hold the power of life and death. Reading commercially printed surgical texts that falsely claim orthodoxy, one finds statements like: "Death occurs instantly if the 'Seven Evils' appear." Another text describes inserting a needle heated with tung oil into phlegm masses half an inch deep, followed by inserting strips of descending medicines for seven days until the mass cracks, then repeating for another seven days until the nodule falls off. It also claims that toxins located between skin and flesh require incisions one cun deep to release poison. In reality, toxins usually lie between the skin and fascia; even if incision is needed, depth should not exceed three fen to avoid damaging internal membranes. Deep incisions risking visceral injury subject patients to torture. The appearance of the "Seven Evils" is rapid; those following such brutal methods are essentially executioners. This collection uses pricking only for carbuncle-herpes (Ding); otherwise, knives and needles are rarely used, and ascending, descending, and cauterizing/rotting drugs are prohibited.
Lesions throughout the body present only in red or white. Red indicates carbuncle; white indicates gangrene. Some call unidentifiable swellings "nameless toxic swelling" due to lack of diagnostic knowledge.
Regardless of whether the lesion is on the back, neck, waist, or abdomen, white lesions are termed gangrene and treated with gangrene-specific medicines; red and swollen lesions are termed carbuncles and treated with carbuncle-specific medicines. Commercial books suggest trying one medicine and switching to another if ineffective. Is this not using humans as test subjects? If a lesion arises at a critical acupoint, how can doctors experiment? Wise practitioners should deliberate carefully.
There are no chronic, non-healing carbuncles in the world. Only when early-stage gangrene fails to resolve, or is mistreated with descending drugs, moxibustion, needling, or cutting, does it persist for years. Detailed treatments for such cases are included here.
Wherever this collection spreads, diligent practitioners will naturally resolve early-stage lesions and heal ulcerated ones. I fear that in remote areas where it arrives late, doctors may not have seen it, and people may not be familiar with it. Thus, I commissioned its reprinting to spread it rapidly across the land, ensuring physicians possess life-saving skills and patients do not die unjustly, fulfilling my wish.
The book contains formulas for carbuncles, gangrenes, throat diseases, carbuncle-herpes, syphilitic sores, various ulcers, hemorrhoids, and fistulas—all guaranteed effective. Additionally, fifty formulas for miscellaneous diseases, each curing specific ailments with a single dose, are appended. These contain no errors of human experimentation. Those with means should prepare these medicines and distribute them to the sick, charging only for cost price. If copying and transmitting the formulas, please note the preparation methods.
All medicinal ingredients used in this book are listed in the final volume. Preparation instructions must not be ignored; careful adherence ensures pure potency and rapid efficacy.
Typhoid fever (Shanghan) involves transmission and transformation of meridians, hence the saying that physicians should not rigidly stick to fixed formulas. In contrast, surgical miscellaneous diseases rely entirely on recognizing symptoms and adhering to specific formulas. At seventy-two years old, having practiced medicine for over forty years without error, I dare to compile this collection and publish it publicly, naming it *Zheng Zhi Quan Sheng* (Complete Life Preservation Based on Symptoms).
