所谓伤寒，病情险恶严重，症状头绪繁多。如果不是通过询问病因、察验症状、确定病名，没有不出现误诊的。凡是到了病人家中，首先要了解：是否刚吃饱饭，或者平时体质虚弱，或者平时体质壮实，或者素来有其他病症，或者向来没有其他病症。这就是询问病因的方法。六经的形体和症状，各自应当详细审察。太阳病，出现发热、恶寒、头项部都疼痛、腰脊部都僵硬、恶心拘急、身体疼痛骨头酸痛，这是太阳表症，属于标病。如果内热烦躁口渴、小便不利，这是太阳里症，属于本病。脉象浮紧有力的是伤寒，浮缓无力的是伤风，脉象安静的是病未传变，脉象躁动盛大的是病欲传变。阳明病，身体发热，轻微恶寒，头额眼部疼痛，鼻子干燥不能安眠，这是阳明表症，属于标病。如果烦躁口渴想喝水，出汗怕热，这是阳明里症，属于本病。如果出现潮热自汗，胡言乱语、口渴、腹部硬满，发斑发黄、狂乱便秘，这是正阳明胃实，属于腑病。脉象微洪是标病，洪数是本病，沉数是实证。少阳病，头角疼痛且目眩，胸胁疼痛且耳聋，寒热往来、呕吐且口苦，这是少阳经病。其经络处于半表半里之间，其脉象既弦又数。太阳病（此处原文似有误，结合上下文应为太阴病或邪传太阴），壮热，咽干，或者自利而不渴，这是阳经热邪传入太阴，属于标病。如果燥渴发黄，尿赤便秘，这是太阴本病。如果初起发病，没有头疼、口渴、发热，而是大便寒冷、腹部胀满疼痛，呕吐腹泻呃逆，这是太阴直中本病。如果初起不发热，只是胀满嗳气疼痛，这是生冷内伤。脉象沉缓是标病，沉实是本病，直中与内伤寒皆见沉细脉。少阴病，舌干口燥，胡言乱语、口渴、便秘，这是阳经热邪传入少阴，属于标病。如果身体发热面色红赤，脚冷脉沉，这是肾经夹阴伤寒，标本俱病。阴躁欲坐于泥水井中，虽然想喝水但又不受纳，面赤足冷脉沉，这是阴极发躁，属于本病。如果面赤足冷，烦躁想喝水，掀去衣被，脉数大无力，这是虚阳伏阴，标与本同病。如果初起发病，没有头疼、发热、口渴，而是四肢厥冷蜷卧，脐腹都疼痛，呕吐腹泻战栗，这是肾经直中本病。更兼有小腹绞痛，或者呕吐腹泻，甚至舌头卷缩、睾丸上缩，这是夹阴中寒，也是本病。脉象沉实有力，是阳邪标病；沉细无力，是直中寒症；数大无力，是虚阳伏阴；脉沉，是夹阴伤寒。厥阴病，寒热像疟疾一样，这是阳邪传入厥阴，属于标病。如果舌头卷缩、睾丸上缩，烦闷便秘口渴，手足时而温暖时而寒冷，这是阳邪传入厥阴，属于本病。如果初起发病，没有头疼、发热、口渴，而是怕寒厥冷，腹部阴处都疼痛，吐沫泄利，舌头卷缩、睾丸上缩，这是厥阴直中本病。脉象浮缓是标病，沉实是本病，细软是直中。头痛拘急，身体发热恶寒，腹痛呕吐，气口与人迎脉都盛大，这是夹食伤寒。身体发热恶寒，头痛微汗，神疲倦怠懒言，这是劳力伤寒。身体发热恶寒，隐隐头痛，喘咳烦闷，左脉紧盛，右脉洪滑，这是夹痰伤寒。身体发热恶寒，头胁都疼痛，气郁不舒，这是夹气伤寒。胸胁腹痛，痛处固定不移，头痛烦躁口渴，身体发热恶寒，这是血郁伤寒。更有伤暑、伤湿、温病、热病、冬温、风温、温毒、温疟、风湿、湿温、疫病、痉病，都必须辨别确切并确定病名，根据病名施治，然后才能万举万当。在表的用汗法、散法；在里的用利法、下法；在半表半里的用和解法；在上的用涌吐法；下陷的用升提法；夹阴的用补法；直中的用温法。对于表里、阴阳、虚实、寒热、标本，要像分辨黑白一样清楚，绝无迷惑。症状有变化，治疗不拘泥固执，轻重缓急，运用无误，可以说是懂医而无愧于掌握生命大权了。
Use realgar (Realgar) processed by water levigation. For males, blow into the left nostril; for females, into the right nostril. Alternatively, take a piece of transparent realgar weighing five qian, wrap it in silk, and tie it to the top of the head (Baihui acupoint area); this is excellent.
Drink water infused with Cyatheae Spicam (Guanzhong). Soak Adzuki beans (Chixiaodou) together with glutinous rice in a water vat, and use this water daily.
Shanghan (Cold Damage) involves a dangerous and severe disease progression with numerous and complex symptoms. Without inquiring into the cause, examining the symptoms, and correctly naming the disease, misdiagnosis is inevitable. Upon arriving at the patient's home, one must first ascertain: whether they have just eaten a full meal, or if their constitution has always been deficient, or always excess, or if they have had other chronic conditions, or if they have never had other conditions. This constitutes the method of inquiring into the cause. The manifestations and symptoms of the Six Channels (Liu Jing) must be carefully examined for each. In Taiyang disease (Taiyang Disease), presenting with fever, aversion to cold, pain in the head and nape, stiffness in the waist and spine, nausea with tension, body ache, and bone pain, these are Taiyang exterior syndromes, representing the Biao (Branch/Manifestation) aspect. If there is internal heat, irritability, thirst, and difficult urination, these are Taiyang interior syndromes, representing the Ben (Root/Essence) aspect. A pulse that is floating, tight, and forceful indicates Shanghan (Cold Damage); floating, slow, and weak indicates Shangfeng (Wind Strike); a quiet pulse indicates no transmission; a restless and vigorous pulse indicates impending transmission. In Yangming disease (Yangming Disease), presenting with body heat, slight aversion to cold, pain in the forehead and eyes, dry nose, and insomnia, these are Yangming exterior syndromes, representing the Biao aspect. If there is irritability, thirst with desire to drink, sweating, and aversion to heat, these are Yangming interior syndromes, representing the Ben aspect. If there is tidal fever, spontaneous sweating, delirium, thirst, abdominal hardness and fullness, macules, jaundice, mania, and constipation, this is Zheng Yangming Stomach Excess, representing the Fu (Hollow Organ) disease. A slightly surging pulse indicates Biao; a surging and rapid pulse indicates Ben; a deep and rapid pulse indicates Excess. In Shaoyang disease (Shaoyang Disease), presenting with pain in the temples and dizziness, chest and hypochondriac pain, deafness, alternating chills and fever, vomiting, and bitter taste, this is Shaoyang Channel disease. Its channel is located between the exterior and interior, and its pulse is both wiry and rapid. [Note: Text says "Taiyang" here but context implies transmission to Taiyin] When strong fever, dry throat, or spontaneous diarrhea without thirst occur, this is Heat Evil from the Yang channels transmitting into Taiyin, representing the Biao aspect. If there is dryness, thirst, jaundice, red urine, and constipation, this is Taiyin Ben disease. If upon initial onset, there is no headache, thirst, or fever, but rather cold stool, abdominal distension, fullness, pain, vomiting, diarrhea, and hiccups, this is Taiyin Zhi Zhong (Direct Invasion) Ben disease. If initially there is no fever, only distension, belching, and pain, this is injury from cold and raw food. A deep and slow pulse indicates Biao; a deep and solid pulse indicates Ben; both Zhi Zhong and internal cold injuries present with deep and fine pulses. In Shaoyin disease (Shaoyin Disease), presenting with a dry tongue, dry mouth, delirium, thirst, and constipation, this is Heat Evil from Yang channels transmitting into Shaoyin, representing the Biao aspect. If there is body heat, flushed face, cold feet, and a deep pulse, this is Kidney Channel Jia Yin Shanghan (Cold Damage with Yin involvement), where both Ben and Biao are affected. Restlessness due to Yin excess, desiring to sit in a muddy well, wanting to drink but unable to retain fluids, with a flushed face, cold feet, and deep pulse, indicates Extreme Yin generating restlessness, which is Ben disease. If there is a flushed face, cold feet, irritability, desire to drink, removing clothes and blankets, with a rapid, large, and forceless pulse, this is Deficient Yang hidden within Yin, affecting both Biao and Ben. If upon initial onset, there is no headache, fever, or thirst, but rather cold limbs, curling up, pain in the umbilicus and abdomen, vomiting, diarrhea, and shivering, this is Kidney Channel Zhi Zhong Ben disease. If accompanied by severe colic in the lower abdomen, or vomiting and diarrhea, even to the point of tongue retraction and testicular retraction, this is Jia Yin Zhong Han (Cold invasion with Yin involvement), also Ben disease. A deep, solid, and forceful pulse indicates Yang Evil Biao disease; a deep, fine, and forceless pulse indicates Direct Invasion Cold syndrome; a rapid, large, and forceless pulse indicates Deficient Yang hidden within Yin; a deep pulse indicates Jia Yin Shanghan. In Jueyin disease (Jueyin Disease), alternating chills and fever resembling malaria indicates Yang Evil transmitting into Jueyin, representing the Biao aspect. If there is tongue retraction, testicular retraction, irritability, fullness, constipation, thirst, and hands and feet alternating between warm and cold, this is Yang Evil transmitting into Jueyin, representing the Ben aspect. If upon initial onset, there is no headache, fever, or thirst, but rather aversion to cold, cold limbs, pain in the abdomen and genital region, vomiting saliva, diarrhea, tongue retraction, and testicular retraction, this is Jueyin Zhi Zhong Ben disease. A floating and slow pulse indicates Biao; a deep and solid pulse indicates Ben; a fine and soft pulse indicates Direct Invasion. Headache with tension, body heat with aversion to cold, abdominal pain with vomiting, and both Qikou (Radial artery) and Renying (Carotid artery) pulses being vigorous indicate Jia Shi Shanghan (Cold Damage with Food Retention). Body heat with aversion to cold, headache with slight sweating, mental fatigue, and reluctance to speak indicate Laoli Shanghan (Cold Damage due to Overexertion). Body heat with aversion to cold, vague headache, wheezing, coughing, and irritability, with a tight and vigorous left pulse and a surging and slippery right pulse, indicate Jia Tan Shanghan (Cold Damage with Phlegm). Body heat with aversion to cold, pain in the head and hypochondrium, and Qi stagnation with discomfort indicate Jia Qi Shanghan (Cold Damage with Qi Stagnation). Chest, hypochondriac, and abdominal pain that does not move after pressing, headache, irritability, thirst, body heat, and aversion to cold indicate Xue Yu Shanghan (Cold Damage with Blood Stasis). Furthermore, Shang Shu (Summerheat Injury), Shang Shi (Dampness Injury), Wen Bing (Warm Diseases), Re Bing (Heat Diseases), Dong Wen (Winter Warmth), Feng Wen (Wind Warmth), Wen Du (Warm Toxicity), Wen Nue (Warm Malaria), Feng Shi (Wind-Dampness), Shi Wen (Damp-Warmth), Yi Bing (Epidemic Diseases), and Jing Bing (Spasm Disease) must all be distinguished accurately and named correctly. Treatment should be administered according to the name, thereby ensuring every action is appropriate. For those in the exterior, apply sweating and dispersing methods; for those in the interior, apply draining and purgative methods; for those between exterior and interior, apply harmonizing methods; for those in the upper jiao, apply emetic methods; for those sinking, apply lifting and raising methods; for Jia Yin cases, apply tonification; for Zhi Zhong cases, apply warming. Regarding exterior-interior, yin-yang, deficiency-excess, cold-heat, and root-branch, one must distinguish them as clearly as black and white, with absolutely no confusion. As symptoms change, treatment should not be rigid. Handling severity and urgency without error demonstrates true medical knowledge, worthy of wielding the power over life and death.
