夫六气之胜，元相为邪，随其所乘，而生其病，不必皆然。邪淫已胜，而为病始，故有虚实
微正贼之五邪也。大凡治病，先求其病之由，次审病之所，知本知标，而悉明矣。其胜者，风胜
则耳鸣头眩，愦愦欲吐，胃膈如塞，大风数举，裸虫不滋， 胁气并，偏着一边，化而为热，小
便黄赤，胃脘当心而痛，上支两胁，肠鸣飧泄，小腹痛，注下赤白，甚则呕吐，膈咽不通，饮食
入而复出也。热甚则心下热，善饥，脐下反动，气游三焦，炎暑至，木流津，草乃萎，呕逆躁烦，
腹满溏泄，传为赤沃也。湿胜则火气内郁，寒迫下焦，痛留囟顶，互引眉间，胃满，雨数至，鳞
见放陆，燥乃化见，少腹满，腰膝重强，内不便，善注泄，足不温，头重， 肿，饮发于中，
肿于上，湿胜及火气内郁，则疮疡于中，流散于外，病在 胁，甚则心痛，热格头痛，喉痹项
强。火胜则热客于胃，烦心心痛，目赤欲呕，呕酸善饥，心痛溺赤，善惊谵外家，暴热消烁，草萎
水涸，介虫乃屈，少腹痛，下沃赤白。燥
胜则清发于中，左 胁痛，溏泄，内为嗌塞，外发 疝，大凉肃杀，华英改容，毛虫乃殃，胸中
不便，嗌塞而咳。寒胜则凝栗且至，非时水冰，羽虫后化，痔，疟发，寒厥入于胃，则内为心痛，
阴中生疮，隐曲不利，互引阴股，筋肉拘苛，血脉凝泣，络满色变，或为血泄，皮肤否肿，腹满
食减，热反上行，头项脑户中痛，目如脱，寒入下焦，传为濡泄。
六气（风、热、火、湿、燥、寒）的偏胜，其元气相互作用成为邪气，随着所乘袭的部位不同，而产生相应的疾病，情况并非完全固定。邪气淫溢且占据优势后，疾病才开始显现，因此存在虚实以及微正贼五种邪气的区别。大凡治疗疾病，首先要探究病因，其次审察病位，明白了本与标，就能全面通晓了。
风气偏胜，则出现耳鸣、头晕目眩，心中烦闷欲吐，胃脘和膈部感觉像堵塞一样；大风频繁刮起，裸体之虫（无鳞甲毛羽覆盖的动物）不能滋生；胁肋之气并聚，病势偏注于一侧；风气化热，导致小便黄赤，胃脘当心处疼痛，向上支撑两胁，肠鸣飧泄，小腹痛，痢下赤白，严重时呕吐，膈部和咽喉不通，饮食吃进去又吐出来。
热气偏胜，则心下部发热，容易饥饿，脐下有跳动感，气游走于三焦；炎暑到来，木气流动津液，草木枯萎；出现呕逆、躁动烦乱，腹部胀满、溏泄，进而发展为便下脓血（赤沃）。
湿气偏胜，则火气在内郁结，寒气逼迫下焦，疼痛停留于囟顶，牵连眉间；胃部胀满；雨水频繁降临，鳞介之虫（水生动物）出现在陆地，燥气随之显现；少腹胀满，腰膝沉重僵硬，体内排便不畅，容易腹泻，足部不温，头部沉重，浮肿，水饮发于中焦，浮肿见于上部。若湿气偏胜兼有火气内郁，则在体内发生疮疡，流散于体表；病位在胁肋，严重时心痛，热格头痛，喉痹，项强。
火气偏胜，则热邪客居于胃，心烦心痛，眼睛发红欲吐，呕吐酸水，容易饥饿，心痛伴小便红赤，易受惊吓、说胡话；突然高热消烁万物，草木枯萎，水干涸，介壳之虫（带壳昆虫等）屈伏；少腹痛，便下脓血。
燥气偏胜，则清冷之气发于中焦，左侧胁肋疼痛，溏泄，内部咽喉阻塞，外部发生疝气；大凉肃杀之气使花叶改变容貌，毛虫遭受灾殃；胸中不适，咽喉阻塞而咳嗽。
寒气偏胜，则凝结战栗之气到来，非时令季节水结冰，羽虫（鸟类）后化生；发生痔疮，疟疾发作；寒厥进入胃中，则在内部引起心痛，阴部生疮，大小便或性生活不利，互相牵引至大腿内侧，筋肉拘急苛刻，血脉凝滞涩阻，络脉充盈颜色改变，或者出现便血，皮肤闭塞浮肿，腹部胀满，食欲减退；热邪反而上行，导致头项、脑户部位疼痛，眼球突出感；寒气进入下焦，传变为濡泄（稀薄的水样腹泻）。
The excessive influence of the Six Qi (Wind, Heat, Fire, Dampness, Dryness, Cold), where their primal energies interact to become pathogenic factors, generates diseases according to the sites they invade; this is not always uniform. Once the pathogen becomes excessive and dominant, the disease begins to manifest, thus giving rise to the five types of pathogens characterized by deficiency/excess and minor/major/orthodox/rebellious/negative natures. Generally, in treating diseases, one must first seek the origin of the disease, then examine the location of the pathology. Understanding both the root (Ben) and the branch (Biao) leads to comprehensive clarity.
When Wind is excessive, there is tinnitus and dizziness, a sense of mental confusion with nausea, a sensation of blockage in the stomach and diaphragm; frequent strong winds blow, naked creatures (animals without scales or feathers) fail to thrive; Qi gathers in the hypochondrium, biasing to one side; transforming into Heat, it causes yellow-red urine, pain in the epigastrium at the heart's location, radiating upward to support both hypochondria, borborygmus with undigested food diarrhea, lower abdominal pain, dysentery with red and white discharge, and in severe cases, vomiting, obstruction of the diaphragm and pharynx, where food enters and immediately returns.
When Heat is excessive, there is heat in the epigastrium, frequent hunger, rebounding movement below the umbilicus, Qi wandering through the San Jiao (Triple Burner); when scorching summer arrives, Wood flows with fluids, grasses wither; symptoms include retching, restlessness, and irritability, abdominal fullness, loose stools, which transmit into bloody purging (Chi Wo).
When Dampness is excessive, Fire Qi is internally constrained, Cold presses upon the Lower Jiao; pain lingers at the fontanelle, radiating to the glabella; gastric fullness occurs; rain falls frequently, scaled creatures appear on land, Dryness manifests; lower abdominal fullness, heavy and stiff waist and knees, internal difficulty in defecation, prone to profuse diarrhea, cold feet, heavy head, edema; fluid retention originates in the middle, swelling appears above. If Dampness is excessive combined with internal Fire constraint, sores and ulcers arise internally and spread externally; the disease is located in the hypochondrium, and in severe cases, heart pain, heat-block headache, bi-syndrome of the throat, and stiffness of the neck.
When Fire is excessive, Heat lodges in the Stomach, causing vexation, heart pain, red eyes, desire to vomit, vomiting of sour fluid, frequent hunger, heart pain with red urine, frightfulness, and delirium; sudden intense heat scorches, grasses wither, waters dry up, shell-bearing creatures submit; lower abdominal pain, bloody purging.
When Dryness is excessive, clear/cold Qi arises in the middle, causing left-sided hypochondriac pain, loose stools, internal pharyngeal obstruction, external manifestation of hernia; severe cool and austere killing energy changes the appearance of flowers and leaves, hairy creatures suffer calamity; chest discomfort, pharyngeal obstruction with cough.
When Cold is excessive, coagulating and shivering Qi arrives, water freezes out of season, feathered creatures transform late; hemorrhoids occur, malaria attacks; Cold Jue (reversal) enters the Stomach, causing internal heart pain, sores in the yin region, difficulty in urination/defecation or sexual function, radiating to the inner thighs, muscle and tendon cramping and rigidity, blood vessels becoming stagnant and obstructed, collaterals full with color changes, or hematochezia, skin obstruction and edema, abdominal fullness, reduced appetite; Heat reversely moves upward, causing pain in the head, neck, and occiput, sensation of eyes protruding; Cold enters the Lower Jiao, transmitting into Ru Xie (watery diarrhea).
