疮疡、疽病等病症，种类繁多，各不相同。再加上各地土壤所产药材的浓淡厚薄不同，人的年龄老幼、体质虚实各异，形体与情志的苦乐也不尽相同，因此各有适宜的治疗方案。难道会有一种固定的方法或一方通治所有情况吗？然而，医生若能精通医理，领悟权衡变化的机巧，谁敢用一成不变的方剂来求取痊愈呢？（治愈的机会就很少了。）朱丹溪说：“用古方治疗今人的疾病，就像拆除旧屋改建新房，尺寸怎么能完全吻合呢？必须经过优秀工匠之手，才能契合。”同理，用古方治疗今人的疾病，必须经过良医之手，才能得其适宜。所以先贤确立了补法、泻法、汗法、下法、针灸、淋洗、敷贴、艾灸、烙法等治疗方法，都是取其合乎时宜的作用。应当考察疮疡的缓急、病势的轻重、治疗的汗下之法、方法的逆从原则、病症的标本关系、方剂的奇偶配伍，这些都在于医生的灵活变通。寒热温凉药性的汤液加减，贵在临症处方时，运用一时通变的机巧，从而取得百发百中的疗效。
凡是疮疽病症，痛苦在于疼痛或瘙痒。需根据患者的虚实、脉象的浮沉、病症的表里来判断。如肿疡初起，应当采用内疏法；脓已成之后，即当采用内托法，以止痛排脓；溃破之后，须当大补气血。这是正治的方法。若兼有其他症状，也应当随之加减，使其适宜而安。稍列几味药物，以阐明随症制宜的道理，略言数句，以说明活法的要点。例如：溃后头痛，在托里方中加入川芎、蔓荆子；溃后惊悸，加入人参、茯神、朱砂；寒热往来，加入柴胡、地骨皮；口渴不止，加入天花粉、知母；大便秘结，加大黄、火麻仁，严重时加芒硝；小便不通，加入茯苓、琥珀、木通、车前子；心虚烦闷，加入天门冬、枸杞子；四肢厥冷，加入附子、干姜；呕吐者，加入生姜、半夏、藿香；脓多者，加入川芎、当归；痛甚者，加入乳香、芍药；肌肉不生，加入人参、白术、川芎、当归；疮口不收敛，加入白蔹、白及；风痒痛，加入防风、天麻；肌肉坏死，加入独活、官桂；疮色紫暗阴黑，加入没药、红花。所述不尽，请遍览参考。
Conditions such as sores and carbuncles vary greatly in their manifestations. Furthermore, the density and quality of medicinal materials produced by the soil of different regions differ; people vary in age (young or old), constitution (deficient or excess), and physical and emotional states (suffering or joy). Each situation has its own appropriate treatment. How could there be a single method or formula that applies universally? However, if a physician masters medical principles and comprehends the flexibility of weighing and adapting to changes, few would dare to seek cure with a rigid, unchanging formula. Zhu Danxi stated: "Using ancient formulas to treat modern diseases is like demolishing an old house to build a new one; how can the dimensions match perfectly? It requires the hand of a skilled craftsman to ensure a proper fit." Similarly, using ancient formulas to treat modern diseases requires the expertise of a competent physician to achieve appropriateness. Therefore, the sages established various therapeutic methods such as tonification (Bu), purgation (Xie), diaphoresis (Han), catharsis (Xia), acupuncture, moxibustion, washing, topical application, burning, and cautery, all chosen for their suitability to the specific context. One must examine the urgency of the sore, the severity of the condition, the choice between diaphoretic and cathartic treatments, the principle of following or opposing the disease pattern, the root and branch of the symptoms, and the odd-even composition of the formula. All these depend on the physician's adaptive discretion. The addition and subtraction of decoctions with cold, heat, warm, and cool properties rely on the physician's ability to apply timely adaptability when prescribing, thereby achieving high efficacy ("hitting the mark every time").
In cases of sores and carbuncles, the primary distress lies in pain or itching. Diagnosis depends on the patient's deficiency or excess, the floating or sinking pulse, and the exterior or interior nature of the syndrome. If swelling is in the initial stage, internal dispersal (Nei Shu) should be employed. Once suppuration has formed, internal support (Nei Tuo) should be used to relieve pain and drain pus. After ulceration, substantial tonification is required. This constitutes the standard treatment approach. If other concurrent symptoms exist, they should also be addressed through appropriate modifications. Here are a few examples to illustrate the principle of treating according to symptoms, briefly outlining the essentials of flexible therapy: For headache after ulceration, add Chuanxiong Rhizome (Chuanxiong) and Browneae Semen (Manjingzi) to the supporting formula; for palpitations and fright after ulceration, add Ginseng Radix et Rhizoma (Renshen), Poria (Fushen), and Cinnabar (Zhusha); for alternating chills and fever, add Bupleuri Radix (Chaihu) and Cortex Lycii Radicis (Digupi); for persistent thirst, add Trichosanthis Radix (Huafen) and Anemarrhenae Rhizoma (Zhimu); for severe constipation, add Rheum Palmatum Radix et Rhizoma (Dahuang) and Cannabis Fructus (Mazi), and if severe, add Mirabilite (Mangxiao); for urinary obstruction, add Poria (Fuling), Amber (Hupo), Akebia Caulis (Mutong), and Plantaginis Seed (Cheqian); for heart deficiency with restlessness, add Asparagi Radix (Tianmendong) and Lycii Fructus (Gouqi); for cold limbs, add Aconiti Lateralis Radix Praeparata (Fuzi) and Zingiberis Rhizoma (Ganjiang); for vomiting, add Zingiberis Rhizoma Recens (Shengjiang), Pinelliae Rhizoma (Banxia), and Agastaches Herba (Huoxiang); for excessive pus, add Chuanxiong Rhizome (Chuanxiong) and Angelicae Sinensis Radix (Danggui); for severe pain, add Boswelliae Resina (Ruxiang) and Paeoniae Radix Alba (Shaoyao); for lack of tissue regeneration, add Ginseng Radix et Rhizoma (Renshen), Atractylodis Macrocephalae Rhizoma (Baizhu), Chuanxiong Rhizome (Chuanxiong), and Angelicae Sinensis Radix (Danggui); for non-healing wounds, add Ampelopsis Radix (Bailian) and Bletillae Rhizoma (Baiji); for wind-induced itching and pain, add Saposhnikoviae Radix (Fangfeng) and Gastrodia Rhizoma (Tianma); for necrotic flesh, add Actaeos Radix (Duhuo) and Cinnamomi Cortex (Guangui); for purple or dark black lesions, add Myrrha (Moyao) and Carthami Flos (Honghua).
