【方歌】阳证初起焮赤痛，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，焮热赤痛根束者，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。
【方歌】阴证初起如粟大，不红不肿疙瘩僵，木硬不痛不焮热，
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，如粟米大之疙答，不红不肿，不焮热，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。
【方歌】阴阳相半属险证，阳吉阴凶生死昭，似阳微痛微焮肿，
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，似阳不甚焮热肿痛，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。
【方歌】阳证在初起时，患处红肿灼热且疼痛，疮根界限清晰，肿胀高耸如弓背。发病后七天左右，疼痛时而剧烈时而缓解，到了第十四天左右，疮内逐渐化脓。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。新生的肌肉像珍珠一样圆润美观，色泽鲜艳润泽如同石榴籽般红润。自然状态下不会犯“七恶”之症，反而应当遇到“五善”之吉兆。必须知道这属于纯阳证，只要医药调理得当，自然会有疗效。
【注】凡是痈疽初起，出现红肿灼热、疼痛且疮根收敛的，说明病邪晕散范围局限；“盘清”是指不呈现漫肿状态；“肿如弓”是指高肿突起。这些都属于阳证。因此，在溃破排脓、脱落腐肉、生出新肉以及收口愈合的过程中，都表现得比较容易。
【方歌】阴证在初起时，疮形小如粟米，不红不肿，疙瘩僵硬，质地木硬且不痛不发热，疮根平铺宽大，颜色暗滞无光泽。过了七天之后，既不溃破也不腐烂，疮面塌陷柔软，没有脓液形成，结成空壳般的仓廪，疮面上生长的肉芽像脱落的甲片，疮孔中结出的硬块好似花中含苞待放。若见脓液紫黑稀薄且多臭秽，一旦见到“七恶”征象，便知预后不良难以存活。必须知道这属于纯阴证，即使有神医扁鹊、黄帝那样的医术，生命也难以长久。
【注】凡是痈疽初起，形态小如粟米的疙瘩，不红不肿，不灼热，质地木硬且不痛，疮根散漫无边，颜色暗滞无光泽的，这些都属于阴证，因此难以溃破腐烂。若出现空仓无脓、肉芽如甲叶般不脱落、孔中结子如花含子、脓液紫黑稀薄且臭秽等情况，均属于难治之症。
【方歌】阴阳相兼属于险证，阳证主吉、阴证主凶，生死界限分明。症状似阳证但仅有轻微疼痛和轻微红肿，似阴证但既有硬化又有部分高肿。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）。虽然可能兼见“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觉得味道鲜美，大小便调和尚可治疗。按照法则施治，往往能应手取效，阳气增长、阴气消退，病情自然可以调愈。
【注】凡是痈疽，症状似阳证但灼热肿痛不明显，似阴证但木硬平陷不严重，这属于半阴半阳的险证。如果逐渐出现善证则预后良好可生存，如果逐渐出现恶证则预后不良会死亡。
[Verse] In the initial stage of a Yang syndrome, the affected area is red, swollen, burning, and painful. The base of the sore is well-defined, and the swelling is high and convex like the back of a bow. Around the seventh day, pain may fluctuate between intense and mild; by the fourteenth day (two sevens), pus gradually forms within the lesion. Pain decreases as pus drains, and the patient feels refreshed. As necrotic tissue sheds and new tissue grows, Qi and Blood become sufficient. The new flesh appears pearly and beautiful in color, fresh and moist like red pomegranate seeds. Naturally, the "Seven Evils" are absent, and the "Five Goods" are present. It must be known that this is a Pure Yang syndrome; with appropriate medical regulation, efficacy will naturally follow.
[Note] Whenever a carbuncle or ulcer begins with redness, swelling, burning, pain, and a contracted base (indicating the pathological spread is localized), clear margins (indicating no diffuse swelling), and high convexity (swelling like a bow), these all belong to Yang syndromes. Therefore, the processes of ulceration, pus discharge, shedding of necrotic tissue, regeneration of new tissue, and wound contraction are all relatively easy.
[Verse] In the initial stage of a Yin syndrome, the lesion is small like a millet seed, without redness or swelling, presenting as a stiff nodule. The texture is woody and hard, without pain or burning heat. The base of the sore is flat, wide, dark, and lusterless. After seven days, it neither ulcerates nor putrefies; it becomes depressed, soft, and devoid of pus, forming an empty cavity. The tissue growing on the sore resembles shed nail plates, and nodules within the pores resemble flowers holding their stamens. If the pus is purple-black, scanty, and foul-smelling, and if the "Seven Evils" appear, death is certain. It must be known that this is a Pure Yin syndrome; even with the medical skills of Qi Bo or Huang Di, life expectancy will be short.
[Note] Whenever a carbuncle or ulcer begins as a millet-seed-sized nodule, without redness, swelling, burning heat, or pain, with a woody-hard texture, a diffuse base, and dark, lusterless color, these all belong to Yin syndromes. Therefore, they fail to ulcerate and putrefy. An empty cavity without pus, tissue resembling nail plates that does not shed, nodules in pores resembling flowers holding seeds, and purple-black, thin, foul-smelling pus are all signs of difficult-to-cure conditions.
[Verse] When Yin and Yang are mixed, it constitutes a dangerous syndrome. Yang indicates auspiciousness, while Yin indicates ominous outcomes, clearly distinguishing life from death. Symptoms may resemble Yang but present only with slight pain and slight swelling; or resemble Yin but show partial hardness and partial elevation. Swelling without ulceration is due to Spleen deficiency; ulceration without healing is due to excessive pus (or insufficient Zheng Qi). Although the "Five Goods" may be partially present, the "Seven Evils" cannot be entirely avoided. If the patient can eat normally and find food tasty, and urination and defecation are regulated, treatment is feasible. Following the correct methods for treatment yields prompt results; as Yang increases and Yin diminishes, the condition can naturally be regulated.
[Note] For any carbuncle or ulcer, where symptoms resemble Yang but lack significant burning heat and swelling/pain, or resemble Yin but lack significant woody hardness and depression, this belongs to a Half-Yin Half-Yang dangerous syndrome. If auspicious signs gradually emerge, survival is possible; if ominous signs gradually emerge, death ensues.
