阳证初起 赤痛，根束盘清肿如弓，七日或疼时或止，二七疮内渐生脓。痛随脓减精神爽，腐脱生新气血充，嫩肉
如珠颜色美，更兼鲜润若榴红。自然七恶全无犯，应当五善喜俱逢，须知此属纯阳证，医药调和自有功。
【注】凡痈疽初起， 热赤痛根束者，晕不散也；盘清者，不漫肿也；肿如弓者，高肿也。此皆属阳之证。故溃脓
脱腐，生新收口，俱见易也。
阴证初起如粟大，不红不肿疙瘩僵，木硬不痛不 热，疮根平大黯无光。七朝之后不溃腐，陷软无脓结空仓，疮上
生衣如脱甲，孔中结子似含芳。紫黑脓稀多臭秽，若见七恶定知亡，须知此属纯阴证，虽有岐黄命不长。
【注】凡痈疽初起，如粟米大之疙瘩，不红不肿，不 热，木硬不痛，疮根散漫，色黯无光者，此皆属阴之证，故
不溃腐，空仓无脓，生衣如甲叶不脱，孔中结子，如花含子，紫黑脓清臭秽，俱见难愈也。
阴阳相半属险证，阳吉阴凶生死昭，似阳微痛微 肿，如阴半硬半肿高。肿而不溃因脾弱，溃而不敛为脓饶，五善
之证虽兼有，七恶之证不全逃。若能饮食知味美，二便调和尚可疗，按法施治应手效，阳长阴消自可调。
【注】凡痈疽，似阳不甚 热肿痛，似阴不甚木硬平陷，此属半阴半阳之险证。若渐生善证则生，渐生恶证则死也。
阳证初起时，患处红肿疼痛，根基收束、边界清晰，肿胀高耸如弓形。发病七日后，疼痛时而剧烈时而缓解；十四日左右，疮口内部逐渐化脓。疼痛随着脓液排出而减轻，患者精神清爽，腐肉脱落、新肉生长，气血得以充盈，新生嫩肉如珍珠般圆润美观，色泽鲜艳润泽如同石榴籽红。若能自然避免“七恶”之症，便会遇到“五善”之吉兆，须知此属纯阳证，只要医药调理得当，自有疗效。
【注】凡是痈疽初起，表现为热、红、痛且根基收束的，说明毒气未扩散（晕不散）；边界清晰的，说明没有漫肿；肿胀高耸如弓的，属于高肿。这些都属于阳证。因此，溃破排脓、脱去腐肉、生出新肉并收敛伤口，都容易实现。
阴证初起时，疮疡如粟米大小，不红不肿，呈疙瘩状僵硬，皮肤麻木坚硬且不痛不热，疮根平塌宽大、颜色暗滞无光泽。七日之后仍不溃烂流脓，反而凹陷柔软、无脓形成，犹如空仓；疮面上生长的肉芽像脱落的指甲，疮孔中结出的硬块好似含苞待放的花蕾。若出现紫黑色、脓液稀少且多臭秽，一旦见到“七恶”之症，便可知预后不良甚至死亡，须知此属纯阴证，即使有神医扁鹊、黄帝般的医术，寿命也难以延长。
【注】凡是痈疽初起，如粟米大小的疙瘩，不红不肿，不热，麻木坚硬且不痛，疮根散漫无边，颜色暗滞无光泽的，都属于阴证。因此难以溃烂流脓，形成空仓无脓的状态，新生的肉芽像甲叶一样不脱落，疮孔中结出硬块，如同花中含子，脓液紫黑清稀且气味臭秽，均显示难以痊愈。
阴阳相半属于险证，阳证主吉、阴证主凶，生死界限分明。症状似阳证但疼痛轻微、肿胀轻微，似阴证但一半坚硬一半肿胀高耸。肿胀但不溃破是因为脾气虚弱；溃破后却不收敛是因为脓液过多（或正气不足无法敛疮）。虽然兼见“五善”之证，但“七恶”之症也难以完全避免。如果患者能正常饮食且知味美，二便调和，尚可治疗。按照法则施治，往往应手而效，阳气增长、阴气消退，病情自然可调愈。
【注】凡是痈疽，症状似阳证但热痛不明显，似阴证但麻木坚硬和平陷不明显，这属于半阴半阳的险证。如果逐渐出现善证则生机在望，逐渐出现恶证则预后不良。
In the initial stage of a Yang syndrome, the affected area is red and painful. The base is confined with clear boundaries, and the swelling is high and arched like a bow. After seven days, pain may fluctuate between severe and mild; by fourteen days (two sevens), pus gradually forms within the lesion. Pain decreases as pus drains, and the spirit becomes refreshed. As necrotic tissue falls off and new tissue grows, Qi and Blood are replenished. The tender new flesh resembles pearls in shape and beauty, appearing fresh and moist, with a color vibrant like pomegranate seeds. If the "Seven Evils" are naturally avoided, the "Five Goods" will likely be encountered. It must be known that this belongs to a pure Yang syndrome; with appropriate medical regulation, efficacy will naturally follow.
[Note] For any carbuncle or ulcer (Yongju) in its initial stage, if it presents with heat, redness, pain, and a confined base, it indicates that the pathogenic influence has not spread (the halo does not disperse); clear boundaries indicate no diffuse swelling; swelling high like a bow indicates prominent elevation. All these belong to Yang syndromes. Therefore, ulceration with pus discharge, shedding of necrotic tissue, regeneration of new tissue, and wound contraction are all easy to achieve.
In the initial stage of a Yin syndrome, the lesion is small like a millet grain, without redness or swelling, presenting as a stiff nodule. The skin is numb and hard, without pain or heat. The base of the sore is flat, wide, dark, and lusterless. After seven days, it fails to ulcerate or shed necrotic tissue; instead, it becomes sunken and soft with no pus formation, resembling an empty granary. Tissue growing on the sore surface resembles detached nails, and nodules forming in the pores look like flowers containing seeds. If purple-black, scanty, and foul-smelling pus appears, and the "Seven Evils" are observed, death is certain. It must be known that this belongs to a pure Yin syndrome; even with the medical skills of Qibo or Huangdi, life expectancy will not be long.
[Note] For any carbuncle or ulcer in its initial stage, if it presents as a millet-grain-sized nodule without redness, swelling, heat, numbness, hardness, or pain, with a diffuse base, dark and lusterless color, it belongs to a Yin syndrome. Therefore, failure to ulcerate, formation of an empty granary without pus, non-shedding of regenerating tissue resembling nail plates, formation of nodules in pores like flowers containing seeds, and purple-black, thin, foul-smelling pus all indicate difficulty in healing.
When Yin and Yang are mixed, it constitutes a dangerous syndrome. Yang syndromes portend good outcomes, while Yin syndromes portend bad outcomes, making life and death distinct. Symptoms resemble Yang but with mild pain and mild swelling; they resemble Yin but with half-hard and half-elevated swelling. Swelling without ulceration is due to Spleen deficiency; ulceration without contraction is due to excessive pus (or insufficient Zheng Qi to close the wound). Although the "Five Goods" may be present, the "Seven Evils" cannot be entirely escaped. If the patient can eat normally and enjoy food, and urination and defecation are harmonious, treatment is feasible. Following proper methods for treatment yields prompt effectiveness; as Yang increases and Yin decreases, recovery can be achieved.
[Note] For any carbuncle or ulcer, if symptoms resemble Yang but with insignificant heat, pain, and swelling, or resemble Yin but with insignificant numbness, hardness, flatness, and depression, it belongs to a semi-Yin, semi-Yang dangerous syndrome. If Good signs gradually appear, survival is expected; if Evil signs gradually appear, death ensues.
