足太阳膀胱经病，凡发热头痛，腰脊强，肩背痛，脉浮紧者，是皆太阳证也。若肩背畏寒，恶
心欲呕，或眼目无神，不欲见人，喜暗畏明，眼眶酸涩，或喜向壁卧，或戴眼上视，或头倾身痛，
甚或颜色清白，隐见青
黑，或丹田无力，息短声微，气促而喘，或咽中闭塞，或角弓发痉，或小水清白，或失小便，或小
便短赤而内不喜冷，凡脉见浮空无力，或沉紧细弱者，皆太阳合少阴之阴证也。足阳明胃经之病，
凡发热，头目痛，不得眠，脉长而数者，本皆阳明证也。若面鼻恶寒，面色清白，或鼻尖冷，口气
不热，或唇口青白微黑，或气短声微，鼻息不长，懒于言语，或戴阳面赤，昏沉困倦多眠，或烦躁
，面赤身热，虚狂假斑，脉反微细无力，或身虽发热，反欲得衣，或口渴不欲饮水，并水浆不入，
或恶寒寒栗，恶心呕逆，或肉 心悸，或动气见于胸腹，或四肢无力，身重懒于举动，或手足自冷
，或肌肉之间以手按之，殊无大热，或大便不实，自利腹痛，凡脉见浮长无力，或短细结促者，皆
阳明合太阴之阴证也。足少阳胆经之病，凡发热，头耳牵痛，胁肋痛，往来寒热，脉见弦数者，本
皆少阳证也。若身虽微热，而时作时止，时多畏寒，或耳聋，或头运，或眼目羞涩，或多惊怯恐畏
，或呕苦吐酸，或恶心喜暖，或爪青筋急囊缩，或厥逆下痢，肠鸣小腹痛，凡脉见弦数无力，而沉
细微弱者，皆少阳合厥阴之阴证也。以上乃三阳经之阴证。阴证者，即阳虚之证也，皆大忌寒凉克
伐之药，妄用即死。余恐将来复有如李子建之流者，故特揭而出之，用为提醒后人之鉴云。
足太阳膀胱经发生病变，凡是出现发热、头痛、腰脊僵硬疼痛、肩背部疼痛、脉象浮紧等症状的，都属于太阳病的范畴。如果伴有肩背部怕冷、恶心想要呕吐，或者眼神无光彩、不想见人、喜欢昏暗环境而畏惧光亮、眼眶酸涩，或者喜欢面向墙壁躺卧，或者眼睛上翻直视（戴眼），或者头部低垂身体疼痛，甚至面色苍白清冷，隐约透出青黑色，或者丹田部位无力、呼吸短促声音微弱、气急喘息，或者咽喉部闭塞感，或者角弓反张发生痉挛，或者小便清长色白，或者小便失禁，或者小便短少色赤但体内并不喜冷饮，凡见脉象浮取空虚无根，或者沉取紧细弱小的，都属于太阳经与少阴经相合的阴证。
足阳明胃经发生病变，凡是出现发热、头目疼痛、无法入睡、脉象长而数的，原本都属于阳明病的范畴。如果伴有面部和鼻部怕冷、面色苍白清冷，或者鼻尖发凉、口中气息不热，或者嘴唇口角青白微黑，或者气短声音微弱、鼻息浅短、懒于说话，或者出现“戴阳”证导致面颊潮红、昏沉困倦多睡，或者烦躁不安、面红身热、虚性狂乱及假性斑疹，脉象反而微细无力，或者身体虽然发热却反而想穿衣服，或者口渴但不想喝水，甚至水浆都无法入口，或者恶寒战栗、恶心呕吐逆气，或者肌肉跳动伴随心悸，或者动气现象出现在胸腹部，或者四肢无力、身体沉重懒于活动，或者手脚自然发冷，或者用手按压肌肉之间感觉不到明显的大热，或者大便不成形、自发性腹泻且腹痛，凡见脉象浮取长而无力的，或者短小细弱结滞急促的，都属于阳明经与太阴经相合的阴证。
足少阳胆经发生病变，凡是出现发热、头部和耳部牵引性疼痛、胁肋部疼痛、忽冷忽热、脉象弦数的，原本都属于少阳病的范畴。如果身体虽然只有轻微发热，但时作时止，平时大多怕冷，或者耳聋，或者头晕，或者眼睛干涩羞明，或者容易受惊胆怯恐惧，或者呕吐苦水和酸水，或者恶心且喜欢温暖，或者指甲青紫、筋脉拘急、阴囊收缩，或者四肢厥冷并伴有下痢、肠鸣和小腹疼痛，凡见脉象弦数但无力，以及沉细微弱的，都属于少阳经与厥阴经相合的阴证。以上所述乃是三阳经的阴证表现。所谓阴证，就是阳气虚衰的病证，都极其忌讳使用寒凉攻伐的药物，如果误用就会致死。我担心将来再出现像李子建那样的人，所以特意揭示并列出这些内容，用作提醒后人的借鉴。
Diseases of the Foot-Taiyang Bladder Meridian: Whenever there is fever, headache, stiffness and pain in the waist and spine, pain in the shoulder and back, and a floating-tight pulse, these are all Taiyang syndrome (Taiyang disease). If accompanied by aversion to cold in the shoulder and back, nausea with a desire to vomit, or dull eyes without spirit, unwillingness to see people, preference for darkness and fear of light, soreness and dryness in the eye sockets, or a preference for lying face down against the wall, or "dai yan" (eyes rolling upward), or head drooping with body pain, or even a pale and clear complexion with faint traces of cyanosis or blackness, or weakness in the Dantian (Lower Abdomen), shortness of breath with a weak voice, rapid breathing with asthma, or a sensation of obstruction in the throat, or opisthotonos (spasm causing arching of the back), or clear and white urine, or urinary incontinence, or short and red urine yet no preference for cold drinks internally; whenever the pulse is found to be floating and empty/weak, or deep, tight, fine, and weak, these are all Yin syndromes where the Taiyang meridian combines with the Shaoyin meridian.
Diseases of the Foot-Yangming Stomach Meridian: Whenever there is fever, pain in the head and eyes, insomnia, and a long and rapid pulse, these originally belong to Yangming syndrome (Yangming disease). If accompanied by aversion to cold in the face and nose, a pale and clear complexion, or a cold nasal tip, non-hot breath from the mouth, or bluish-white and slightly black lips and mouth, or shortness of breath with a weak voice, shallow nasal breathing, reluctance to speak, or "Dai yang" (floating Yang) presenting as facial flushing, lethargy, drowsiness, and excessive sleep, or irritability, facial redness, body heat, virtual mania, and false macules, with a pulse that is instead micro-fine and weak; or although the body has fever, there is a contrary desire to wear clothes; or thirst without a desire to drink water, or inability to take even fluids; or aversion to cold with shivering, nausea, and vomiting/regurgitation; or muscle twitching with palpitations; or "moving Qi" manifesting in the chest and abdomen; or weakness in the four limbs, heaviness of the body, and reluctance to move; or spontaneous coldness of the hands and feet; or upon pressing the muscles, no significant heat is felt; or loose stools, spontaneous diarrhea with abdominal pain; whenever the pulse is floating and long but weak, or short, fine, knotted, or hurried, these are all Yin syndromes where the Yangming meridian combines with the Taiyin meridian.
Diseases of the Foot-Shaoyang Gallbladder Meridian: Whenever there is fever, pulling pain in the head and ears, pain in the hypochondrium, alternating chills and fever, and a string-taut and rapid pulse, these originally belong to Shaoyang syndrome (Shaoyang disease). If although there is slight fever, it comes and goes, and there is often aversion to cold; or deafness; or dizziness; or soreness and dimness of the eyes; or frequent fright, timidity, and fear; or vomiting bitter fluid and sour regurgitation; or nausea with a preference for warmth; or cyanotic nails, taut sinews, and retraction of the scrotum; or cold extremities with dysentery, borborygmus, and lower abdominal pain; whenever the pulse is string-taut and rapid but weak, or deep, fine, and weak, these are all Yin syndromes where the Shaoyang meridian combines with the Jueyin meridian. The above describes the Yin syndromes of the Three Yang meridians. A Yin syndrome refers to a syndrome of Yang deficiency. All such cases strictly prohibit the use of cold-natured and attacking/draining medicines; misuse will result in death. Fearing that future generations may produce individuals like Li Zijian, I have specifically highlighted and presented these points as a warning and reference for later practitioners.
