个，日煎与服，不及十剂，足疮痊愈，升于头顶，照方再服，而头疮亦痊，精神更长。
又治郡中太学生何姓，口舌咽喉腐烂而不疼，胸膈腹闷欲绝，彻夜不寐，饮食不进，
按其脉右寸关弦洪搏指，左寸关沉微欲脱，两尺重按俱无根，询其起病之由，乃平时劳
心，恼怒太过，任病勉强劳碌，以致内伤身热，医家误用发散，乃见红点，便为麻疹，
更用疏解清托，以致困倦愈甚，颊内肿硬、疑为疹毒，更用清凉解毒，于是胸膈胀闷不
堪，后更疼痛欲绝，余始知为药之误也。盖劳伤发热，原系中气不足，误发散而荣气逆
行，乃为斑点，复误用清解，致阴火上浮齿颊而为肿，仍为麻疹余毒，益进寒凉清解，
脾胃愈虚，元阳愈损，阴翳之火，容于咽嗌，腐溃成血而不疼。如物失天日之照临，
则易为之腐坏，故名之为阴烂，非若阳火冲击，为肿溃疼痛也。余始以熟地一两二钱、
炒白术四钱、牛膝三钱、炒麦冬二钱、五味子八分、制附子一钱五分，连进二剂，胸胀
渐减，睡卧始安，六脉少和，次日便用人参三钱、枣仁二钱、熟地四钱、当归一钱五
分、牛膝、炒麦冬各二钱、五味子六分、肉桂去皮八分、姜枣水煎，日进二服，次日六
脉有神，神气亦爽，已能思食，咽喉腐烂之处，亦知少疼矣。此阳和已转之象，盖始知
地之冻，水之死，一得阳和，则冻解而水活矣。故知疼也。余用铜青三钱、 人中白二
钱、西牛黄一分、大冰片二分、麝香一分共研，极细，每回少许吹之，久凝腐溃之痰
涎，长流直涌而出，再吹再流，不日而愈，调理数日，精神日长，饮食日增，余后以八
味加牛膝、五味子为丸，早晨淡盐汤送服五钱，以前方调养心脾气血者，煎成膏滋，晚
间进服，不旬日而痊愈。观此则凡外之肌肉皮毛，内之咽喉肠胃诸症，皆由阴阳偏胜为
患，实气血无形之化也。岂真有外邪有迹之毒，可用寒凉克削者乎！即使火之有余，亦
由水之不足，补水便可以化阳矣。
《经》曰∶邪之所凑，其正必虚，且今人禀赋尤薄，既因虚而受病，焉能耐病而久
延！况芽儿柔脆，血气未全之质乎，故近来温疹之恶，小儿受其害者甚众，盖能受邪
者，正气已虚，一经壮热，阴分燥涸，治者妄投疏表风药，则荣阴转伤，过投攻托毒
药，则中气愈损，再或因其发热，绝其谷食，元气益虚，初则胃气未衰，尚思得食，
久则胃气渐亏，亦不思食，以致有形之疾病未瘳，而无形之元气先脱。更有因药力之
猛，血分沸腾，荣气逆行于表，为斑为疹矣。然有阳气本虚，不能上升，而头面不起
者，亦有中气不足，故起而即没者。亦有久热伤阴，阴虚久热不已者。亦有中气困乏，
不能健运，而不思饮食者。亦有阳无阴敛，孤阳亢上，上壮热喘渴而下虚寒泄泻足冷
者，张每以全真一气投之，燥涸者得此濡润，所谓滋水即所以发汗，况有托住中气之
药，纵有外邪，不能内伏，中气一壮，客气潜消，延纳饮食，精气自生，真火一归于
下，阴翳自解于外，荣阴一润于中，百脉灌溉于表，自然肌肤润泽，热退身凉，里和思
食而愈矣。盖气血变现之症，仍必赖与气血有情之药，投之可入，既有养正耐病之功，
便是却病保命之要，岂可以气血为仇之药，助风助火，日与正气为难首，能不益令受生
诸症，徒使精神竭绝哉！《经》所谓∶致邪失正，绝人长命，此之谓也。
（前文省略，接）每日一剂煎服，不到十副药，足部疮疡痊愈；病邪上移至头顶，照原方再服，头部疮疡也痊愈了，精神更加充沛。
又治疗郡中太学生何某，口舌咽喉腐烂但不疼痛，胸膈腹部闷胀欲绝，整夜无法入睡，饮食不进。诊其脉象，右寸关脉弦洪搏指，左寸关脉沉微欲脱，两尺脉重按均无根。询问发病原因，乃因平时劳心过度，恼怒太过，带病勉强劳作，导致内伤身热。医家误用发散药物，出现红点，便认为是麻疹，更用疏解清托之法，致使困倦愈发严重，颊内肿硬，疑为疹毒，又用清凉解毒之品，于是胸膈胀闷不堪，随后疼痛欲绝。我这才知道是用药错误所致。大概劳伤发热，原本是中气不足，误用发散导致营气逆行，形成斑点；又误用清解，致使阴火上浮至齿颊而肿胀；仍被当作麻疹余毒，进一步进用寒凉清解，脾胃愈虚，元阳愈损，阴翳之火容纳于咽喉，腐溃成血而不疼痛。如同物体失去天日的照耀，则容易腐坏，所以称之为“阴烂”，不同于阳火冲击导致的肿痛。
我开始使用熟地一两二钱、炒白术四钱、牛膝三钱、炒麦冬二钱、五味子八分、制附子一钱五分，连续服用两剂，胸胀逐渐减轻，睡眠开始安稳，六脉稍显调和。次日便用人参三钱、枣仁二钱、熟地四钱、当归一钱五分、牛膝、炒麦冬各二钱、五味子六分、肉桂去皮八分，姜枣水煎，每日进服两次。次日六脉有神，神气清爽，已能思食，咽喉腐烂之处也知道轻微疼痛了。这是阳气已经回转的迹象，大概知道大地冻结、水流枯竭，一旦得到阳和之气，则冻解而水活，所以知道会疼痛。
我使用铜青三钱、人中白二钱、西牛黄一分、大冰片二分、麝香一分，共研极细末，每次少许吹入患处，久凝的腐溃痰涎，长流直涌而出，再吹再流，不久痊愈。调理数日，精神日渐增长，饮食日渐增加。后来我用八味丸加牛膝、五味子制成丸药，早晨用淡盐汤送服五钱，以前方调养心脾气血的药液煎成膏滋，晚间进服，不到十天便痊愈。观察此症，凡外在的肌肉皮毛，内在的咽喉肠胃诸症，皆由阴阳偏胜为患，实则是气血无形之化生。难道真有外邪有迹之毒，可用寒凉克削之法吗！即使火有余，也是由于水不足，补水便可以化阳。
《内经》说：邪气所聚集的地方，正气必定虚弱。况且今人禀赋尤其薄弱，既因虚而受病，怎能耐得住病情长久拖延！何况婴儿柔脆，血气未全的体质呢？所以近来温疹之恶，小儿受其害者甚众。大概能受邪者，正气已虚，一经壮热，阴分燥涸，医者妄投疏表风药，则营阴转伤；过投攻托毒药，则中气愈损；再或因发热，断绝谷食，元气益虚。初时胃气未衰，尚思得食；久则胃气渐亏，亦不思食，以致有形之疾病未愈，而无形之元气先脱。更有因药力猛烈，血分沸腾，营气逆行于表，形成斑疹者。然而有阳气本虚，不能上升，头面不起者；也有中气不足，故起而即没者；也有久热伤阴，阴虚久热不已者；也有中气困乏，不能健运，而不思饮食者；也有阳无阴敛，孤阳亢上，上部壮热喘渴而下部虚寒泄泻足冷者。张景岳每每以全真一气汤投之，燥涸者得此濡润，所谓滋水即所以发汗。况且有托住中气的药物，纵有外邪，不能内伏，中气一壮，客气潜消，延纳饮食，精气自生，真火一归于下，阴翳自解于外，营阴一润于中，百脉灌溉于表，自然肌肤润泽，热退身凉，里和思食而痊愈。盖气血变现之症，仍必赖与气血有情之药，投之可入，既有养正耐病之功，便是却病保命之要，岂可以用与气血为仇的药物，助风助火，日与正气为难，能不更加令受生诸症，徒使精神竭绝哉！《内经》所谓：致邪失正，绝人长命，说的就是这个道理。
(one by one decocted and taken daily, within less than ten doses, the foot sores healed; as the pathogen ascended to the head, taking the same prescription again cured the head sores, and the spirit became even more vigorous.)
Again, he treated a student of the commandery scribe named He, who suffered from rotting and ulceration of the mouth, tongue, and throat without pain, extreme stifling oppression in the chest, diaphragm, and abdomen, sleeplessness throughout the night, and inability to eat or drink. Palpation of his pulse revealed the Right Cun and Guan positions as wiry, surging, and striking the fingers, while the Left Cun and Guan were deep, minute, and on the verge of collapse; both Chi positions lacked root upon heavy pressure. Inquiring about the onset of the illness, it was found that he had previously overworked his mind, experienced excessive anger, and labored strenuously despite being ill, leading to internal injury and fever. The physician mistakenly used dispersing methods. When red spots appeared, they were diagnosed as measles (Ma Zhen). Further use of resolving and clearing methods caused severe fatigue, swelling and hardness inside the cheeks, which was suspected to be measles toxin. More cooling and detoxifying agents were administered, resulting in unbearable chest and diaphragmatic distension, followed by excruciating pain. I then realized this was due to medical error. Generally, fever from labor injury originates from deficiency of Middle Qi. Mistaken dispersion causes Ying Qi to flow counter-currently, forming spots. Subsequent mistaken use of clearing and resolving methods causes Yin Fire to float upward to the teeth and cheeks, causing swelling. Still misdiagnosed as residual measles toxin, further intake of cold and clearing agents further depleted the Spleen and Stomach, damaged Yuan Yang, and allowed Yin shadow fire to lodge in the throat, causing bloody ulceration without pain. Like an object losing the illumination of heaven and sun, it easily rots; hence it is called "Yin Lan" (Yin Ulceration), distinct from the swelling and pain caused by Yang Fire impact.
I initially prescribed Shu Di Huang (Prepared Rehmannia Root) 1 liang 2 qian, Chao Bai Zhu (Stir-fried Atractylodes Macrocephala Rhizome) 4 qian, Niu Xi (Achyranthes Bidentata Root) 3 qian, Chao Mai Dong (Stir-fried Ophiopogon Japonicus Tuber) 2 qian, Wu Wei Zi (Schisandra Chinensis Fruit) 8 fen, and Zhi Fu Zi (Prepared Aconitum Carleilii Lateral Root) 1 qian 5 fen. After two consecutive doses, chest distension gradually decreased, sleep stabilized, and the six pulses became slightly harmonious. The next day, I prescribed Ren Shen (Ginseng Radix) 3 qian, Zao Ren (Ziziphus Jujuba Seed) 2 qian, Shu Di Huang 4 qian, Dang Gui (Angelica Sinensis Root) 1 qian 5 fen, Niu Xi 2 qian, Chao Mai Dong 2 qian, Wu Wei Zi 6 fen, and Rou Gui (Cinnamon Bark) peeled 8 fen, decocted with fresh ginger and jujube, administered twice daily. By the next day, the six pulses showed spirit, the patient's mental state was clear, appetite returned, and the throat ulcers began to feel slight pain. This indicated the return of Yang Harmony. Just as frozen earth and stagnant water revive upon receiving Yang warmth, the return of sensation (pain) indicates recovery.
I prepared Tong Qing (Malachite) 3 qian, Ren Zhong Bai (Human Tooth Ash) 2 qian, Xi Niu Huang (Indian Buffalo Calculus) 1 fen, Da Bing Pian (Borneol) 2 fen, and She Xiang (Musk) 1 fen, ground into an extremely fine powder. Applied sparingly into the lesion, old coagulated phlegm and pus flowed out continuously. Repeated application led to healing within days. After several days of regulation, spirit and appetite improved daily. Later, I formulated Ba Wei Wan (Eight-Ingredient Pill) with added Niu Xi and Wu Wei Zi into pills, taken in the morning with light salt water (5 qian per dose). The previous prescription for nourishing Heart and Spleen Qi and Blood was decocted into a thick paste, taken in the evening. Within ten days, full recovery was achieved. Observing this case, all conditions affecting external muscles and skin, or internal throat and intestines, stem from Yin-Yang imbalance, manifesting as the formless transformation of Qi and Blood. Is there truly any tangible external pathogenic toxin that can be cleared by cold and purgative methods? Even if Fire is excessive, it is due to Water insufficiency; tonifying Water transforms Yang.
The *Classic* states: "Wherever evil gathers, Zheng Qi must be deficient." Moreover, people today have particularly weak constitutions. Having fallen ill due to deficiency, how can they endure prolonged disease? Especially infants, whose tissues are tender and Qi-Blood incomplete. Recently, many children have suffered from malignant warm rashes. Those susceptible to evil already have deficient Zheng Qi. Once high fever occurs, the Yin aspect becomes dry and parched. If physicians recklessly administer wind-dispersing drugs, Ying Yin is further injured. Overuse of toxic-resolving drugs damages Middle Qi further. Or, due to fever, food intake is cut off, further depleting Yuan Qi. Initially, Stomach Qi is not yet exhausted, and hunger persists. Prolonged deficiency leads to loss of appetite. Thus, tangible diseases remain uncured while intangible Yuan Qi collapses first. Some cases involve fierce drug potency causing blood boiling and Ying Qi reversing to the surface, forming macules and papules. However, some have inherent Yang deficiency preventing ascent, so the head and face do not rise (rash fails to erupt); others have insufficient Middle Qi, so the rash appears and disappears quickly; some have prolonged heat injuring Yin, leading to chronic low-grade fever; some have Middle Qi exhaustion failing to transport, causing anorexia; some have Yang without Yin containment, leading to solitary Yang hyperactivity above (high fever, panting, thirst) and deficiency-cold below (diarrhea, cold feet). Zhang Jingyue often uses Quan Zhen Yi Qi Tang (Complete True One Qi Decoction). For those with dryness and parching, this provides moistening—nourishing Water is equivalent to inducing sweating. Moreover, with herbs that anchor Middle Qi, even if external evil exists, it cannot lurk internally. Once Middle Qi strengthens, pathogenic factors dissipate, food intake resumes, Jing Qi generates naturally, True Fire returns downward, Yin shadows resolve externally, Ying Yin moistens internally, and all meridians irrigate the exterior. Naturally, skin becomes lustrous, fever subsides, body cools, interior harmonizes, appetite returns, and healing occurs. Conditions manifesting from Qi and Blood require substances有情 (sentient/nourishing) to Qi and Blood to enter effectively. Such herbs possess the function of nurturing righteousness and enduring disease, which is essential for dispelling illness and preserving life. How can one use drugs hostile to Qi and Blood, aiding Wind and Fire, constantly opposing Zheng Qi, only to exacerbate various ailments and exhaust spirit? As the *Classic* says: "Causing evil to prevail and losing Zheng Qi cuts short human life," this is precisely what is meant.
