论曰∶夫人有四肢、五脏，一觉一寐，呼吸吐纳、精气往来、流而为荣卫，畅而为气
色，发而为声音，阳用其形，阴用其精，此又常数之所同也。至其失也，蒸则生热，否则生
寒，结而为瘤赘，陷而为痈疽，凝而为疮癣，愤则结瘿，怒则结疽；又五脏不和，则九窍不
通；六气不和，则流结为痈。皆经络涩滞，气血不流畅，风毒乘之，而致然也。
愚按∶此论可谓善言人身之造化、疮疡之情状者矣，治法当参详前论。
论曰∶痈疽之症，若七情亏损，气血经络壅结而成者，属内因。若六淫外侵，气血受
伤，寒化而为痈者，属外因。若服丹石补药、膏粱酒面、房劳所致者，属内外因也。又曰∶
阴滞于阳则发痈，阳滞于阴则发疽，脉浮洪滑数为阳，沉缓迟涩为阴，阴则热治，阳则冷
治，初觉宜清热拔毒，已溃宜排脓止痛，故用远志、大黄、甘草，此三因之法也。治当寒者
温之，热者清之，虚者补之，实者泻之，导之以针石，灼之以艾炷，破毒溃坚，各遵成法，
以平为期。
愚按∶前证脉沉实，大便秘结者，属内因也，宜 利之；脉浮大，便调和者，属外因
也，宜托里之；脉不浮不沉者，属不内外因也，宜调和荣卫。此亦治三因法也。若 肿大
痛，烦热饮冷，大便秘结，脉洪数实者，为纯阳，宜苦寒之剂清热拔毒。若不肿不痛，泻利
不食，呕吐足冷，是为纯阴，宜辛热之剂大补阳气。不拘严寒盛暑，当舍时从症。若微肿微
痛，似溃不溃，时出清脓者，为半阴半阳，宜辛热之剂温补胃气，此亦治阴阳症法也。治验
详见首论。
论曰：人拥有四肢和五脏，有醒与睡的状态交替，通过呼吸吐纳使精气在体内往来运行，流动则形成荣气和卫气，通畅则表现为面色光泽，发出来则成为声音。阳发挥其形体作用，阴运用其精微物质，这是普遍遵循的常理。一旦失衡，热气蒸腾则产生热证，寒气凝滞则产生寒证，气血凝结而成肿瘤赘生物，下陷而成痈疽，凝聚而成疮癣，愤懑郁结而成瘿病，愤怒导致而成疽；另外五脏功能不和，则九窍不通畅；六气失调，则流注凝结而成痈。这些都是由于经络涩滞，气血不流畅，风毒趁机侵袭而导致的。
我按语：这段论述可以说是很好地阐述了人体的造化规律以及疮疡的病情状况，治疗方法应当参考前面的论述。
论曰：痈疽的症状，如果是因七情（喜、怒、忧、思、悲、恐、惊）亏损，导致气血经络壅塞结聚而成的，属于内因。如果是六淫（风、寒、暑、湿、燥、火）外邪侵袭，气血受伤，寒邪转化而成痈的，属于外因。如果是服用丹石类补药、膏粱厚味及酒类面食、房事劳损所导致的，属于内外合因。又说：阴气阻滞于阳分则发为痈，阳气阻滞于阴分则发为疽；脉象浮、洪、滑、数属于阳证，脉象沉、缓、迟、涩属于阴证；阴证用热法治疗，阳证用冷法治疗；初起时适宜清热拔毒，溃破后适宜排脓止痛，因此使用远志、大黄、甘草，这是三因（内因、外因、不内外因）的治疗法则。治疗应当对寒证用温法，热证用清法，虚证用补法，实证用泻法，用针石疏导，用艾炷灼灸，破除毒邪溃散坚结，各自遵循既定法则，以平和为最终目标。
我按语：前述症状中，脉象沉实，大便秘结的，属于内因，适宜通利；脉象浮大，大便调和的，属于外因，适宜托里透脓；脉象不浮不沉的，属于不内外因，适宜调和营卫。这也是治疗三因的方法。如果红肿疼痛，烦躁发热想喝冷水，大便秘结，脉象洪数有力的，属于纯阳证，适宜用苦寒药剂清热拔毒。如果不肿不痛，腹泻痢疾不能进食，呕吐且足部冰冷，这属于纯阴证，适宜用辛热药剂大补阳气。不论严寒还是酷暑，都应当舍弃季节因素而顺从病症表现。如果轻微肿胀疼痛，似溃非溃，时常流出清稀脓液的，属于半阴半阳证，适宜用辛热药剂温补胃气，这也是治疗阴阳病症的方法。治疗验案详见首篇论述。
Lun Yue (The Treatise states): Humans possess four limbs and five Zang organs, experience alternating states of waking and sleeping, and through respiration and the exhalation/inhalation of Qi, allow Essence and Qi to circulate. This flow manifests as Ying Qi (Nutritive Qi) and Wei Qi (Defensive Qi), its smoothness reflects in facial complexion, and its emission produces voice. Yang utilizes its form, while Yin utilizes its essence; this is a constant principle shared by all. When imbalance occurs, steaming generates heat, while stagnation generates cold. Condensation leads to tumors or excrescences, sinking leads to carbuncles and sores, coagulation leads to ulcers and tinea, frustration leads to goiter, and anger leads to deep abscesses. Furthermore, disharmony among the five Zang organs results in obstruction of the nine orifices; disharmony among the six Qi (pathogenic factors) leads to flow and condensation causing carbuncles. All these arise from sluggish meridians and collaterals, unsmooth flow of Qi and Blood, and invasion by wind-toxin.
Yu An (Commentary): This treatise can be said to excellently describe the creation of the human body and the conditions of sores and ulcers. Treatment methods should refer to the preceding discussions.
Lun Yue: Regarding symptoms of carbuncles and sores, if they are caused by the deficiency of the Seven Emotions (Joy, Anger, Worry, Pensiveness, Sorrow, Fear, Fright), leading to congestion and knotting of Qi and Blood in the meridians and collaterals, it belongs to Internal Causes. If they are caused by external invasion of the Six Excesses (Wind, Cold, Summer-heat, Dampness, Dryness, Fire), injuring Qi and Blood, where cold transforms into carbuncles, it belongs to External Causes. If they are caused by taking cinnabar/stone tonics, rich foods and alcohol, or sexual exhaustion, it belongs to Both Internal and External Causes. It is also stated: When Yin stagnates in Yang, carbuncles erupt; when Yang stagnates in Yin, deep abscesses erupt. A pulse that is Floating, Surging, Slippery, and Rapid indicates Yang; a pulse that is Deep, Moderate, Slow, and Choppy indicates Yin. Yin conditions are treated with Heat methods, Yang conditions with Cold methods. In the initial stage, clearing heat and extracting toxin is appropriate; after ulceration, draining pus and relieving pain is appropriate. Therefore, Yuanzhi (Polygalae Radix), Dahuang (Rhei Radix et Rhizoma), and Gancao (Glycyrrhizae Radix et Rhizoma) are used. This is the method of the Three Causes. Treatment should warm cold conditions, clear heat conditions, tonify deficiency, drain excess, guide with needles and stones, cauterize with moxa cones, break toxicity and soften hardness, each following established laws, aiming for balance.
Yu An: In the aforementioned cases, a Deep and Solid pulse with constipation belongs to Internal Causes, suitable for purgation/draining; a Floating and Large pulse with normal bowel movements belongs to External Causes, suitable for supporting the interior (Tuo Li); a pulse neither Floating nor Deep belongs to Neither Internal nor External Causes, suitable for harmonizing Ying and Wei Qi. This is also the method of treating the Three Causes. If there is significant swelling and pain, irritability, fever, desire for cold drinks, constipation, and a Surging, Rapid, and Full pulse, it is a Pure Yang condition, suitable for bitter-cold agents to clear heat and extract toxin. If there is no swelling or pain, diarrhea, anorexia, vomiting, and cold feet, it is a Pure Yin condition, suitable for acrid-hot agents to greatly tonify Yang Qi. Regardless of severe cold or intense summer heat, one should disregard the season and follow the symptoms. If there is slight swelling and pain, appearing ulcerated but not truly so, with occasional discharge of clear pus, it is a Half-Yin Half-Yang condition, suitable for acrid-hot agents to warm and tonify Stomach Qi. This is also the method for treating Yin and Yang conditions. Detailed treatment records are found in the first discussion.
