太阳病，关节疼痛而烦，脉沉缓，湿痹之候。其人小便不利，大便反快，只当利其小便，宜五
苓散。（方在可水证中。）
湿家之为病，一身疼，发热，身如熏黄，仍治风湿，脉浮身重，汗出恶风，宜黄 汤。
黄 （二两半） 防己（二两） 甘草（一两） 白术 生姜（各一两半） 枣（十六个）
咀，水四升，煎至二升，去滓，温饮一盏，食久再服。喘者，加麻黄一两；胃中不和者，加
芍药一两半；气上冲者，加桂枝一两半；下有陈寒者，加细辛一
两，服后当如虫行皮中。从腰下如冰，坐浓被上，又以一被绕腰以下，令微汗出。
湿家，其人但头汗出，背强，欲得被覆向火。若下之早则哕，胸满，小便不利，舌上如苔者，
此丹田有热，胸上有寒，渴欲得水而不能饮，口燥故也。
湿家下之，额上汗出，微喘，小便不利者，死；下利不止者，亦死。
问曰∶风湿相搏，一身尽疼痛，法当汗出而解，值天阴雨不止，汗出已解，身复痛，何也？答
曰∶发其汗，汗大出者，但风气去，湿气续在，是故不愈也。若治风湿者，发其汗，但微似欲出汗
者，风湿俱去也。
湿家病身上疼痛，发热，面黄而喘，头痛鼻塞而烦，其脉大，自能饮食，腹中和无病，病在头
中寒湿，故鼻塞，细末瓜蒂，含水搐少许鼻中则愈。
湿家身烦痛，可与麻黄汤内加白术二两。（麻黄汤在可汗证中。）
病者一身尽疼，发热，日晡则剧者，此名风湿。此病因伤于汗出当风，或久伤于冷所致也，可
与杏仁薏苡汤。
麻黄（一两半） 杏仁（四拾五枚） 薏苡仁 甘草（半两）
咀，以水二升，先煮麻黄一二十沸，去上沫，内诸药，煮取一升，去滓，温二三服。
伤寒八九日，风湿相搏，身体烦痛，不能转侧，不呕不渴，脉浮虚而涩者，宜桂枝附子汤。
此治大便自利，小便不利者。
桂枝（二两） 附子（二枚） 生姜（一两半） 大枣（十二枚） 甘草（一两）
咀，以水三升，煮取一升，去滓，分温四服。若大便坚，小便自利者，去桂枝加白术二两，
煎如前法。初一二服，身如痹，半日许服之都尽，其人如冒状，勿怪，此乃术、附并走皮肤，逐水
气未得除，故使之耳。
风湿相搏，骨节疼烦，掣痛不得屈伸，近之则极，汗出短气，小便不利，恶风不欲去被，或有
微肿者，甘草附子汤主之。
附子（二枚） 白术（二两） 桂枝（三两） 甘草（二两）
咀，水三升，煮取一升，去滓，分温三服。身肿者加防己二两；悸气、小便不利加茯苓一两
半，溢水成四升，煎一升三合。
太阳病，出现关节疼痛且伴有烦闷感，脉象沉而缓，这是湿痹的征候。如果患者小便不通畅，大便反而稀溏，治疗应当只通过利小便的方法，适宜使用五苓散。（该方剂记载在“可水证”章节中。）
患有湿病的病人，表现为全身疼痛、发热，身体颜色像被烟熏过的黄色（身如熏黄），此时仍按风湿病治疗；若脉象浮、身体沉重、出汗且怕风，适宜使用防己黄芪汤。
防己（二两半）、黄芪（二两半）、甘草（一两）、白术（一两半）、生姜（一两半）、大枣（十六个）。
将药材切碎，用水四升，煎煮至二升，滤去药渣，温服一盏，饭后过一段时间再服一次。如果气喘，加麻黄一两；胃中不和，加芍药一两半；气上冲，加桂枝一两半；下部有陈寒，加细辛一两。服药后感觉皮肤中有虫爬行的感觉。如果腰部以下冷得像冰一样，可以坐在厚被子上，再用一条被子缠绕腰部以下，使身体微微出汗。
患湿病的人，如果只是头部出汗，背部僵硬，想要盖着被子靠近火源取暖。如果过早使用泻下法，会导致呃逆、胸满、小便不利、舌苔看起来像有苔垢，这是因为丹田有热，胸上有寒，口渴想喝水却喝不下去，是因为口燥的缘故。
对湿病患者误用泻下法，如果出现额头出汗、轻微气喘、小便不利的，预后不良，主死；如果腹泻不止的，也主死。
问：风湿相互搏结，全身都疼痛，按照法则应当通过发汗来解除，如果遇到阴雨天气不停，发汗后虽然暂时缓解，但身体又痛，为什么呢？答：发汗时，如果汗出太多，只有风气被去除，湿气仍然留在体内，所以不能痊愈。如果治疗风湿病，发汗时只要微微似要出汗的样子，风湿之气就能一起去除。
患湿病的人，身上疼痛、发热，面色发黄且气喘，头痛、鼻塞且烦闷，脉象大，能正常饮食，腹部平和没有病痛，这是病邪在头中的寒湿所致，所以鼻塞。将瓜蒂研成细末，含在口中，滴少许入鼻中即可痊愈。
患湿病且身体烦痛的，可以在麻黄汤中加入白术二两。（麻黄汤记载在“可汗证”章节中。）
病人全身都疼痛，发热，傍晚时分加重，这名叫风湿。这种病因是出汗时当风受邪，或长期受寒冷侵袭所致，可以使用杏仁薏苡汤。
麻黄（一两半）、杏仁（四十五枚）、薏苡仁（半两）、甘草（半两）。
切碎，用水二升，先煮麻黄一二十沸，去掉上面的沫，加入其他药物，煮取一升，滤去药渣，分温二三服。
伤寒经过八九日，风湿相互搏结，身体烦痛，不能翻身转动，不呕吐也不口渴，脉象浮虚而涩的，适宜使用桂枝附子汤。
此方适用于大便自利、小便不利的情况。
桂枝（二两）、附子（二枚）、生姜（一两半）、大枣（十二枚）、甘草（一两）。
切碎，用水三升，煮取一升，滤去药渣，分四次温服。如果大便坚硬，小便自利，去掉桂枝，加入白术二两，煎煮方法同上。初服一二剂，身体感觉麻木，约半小时内服完所有剂量，病人会有头晕目眩的感觉，不要奇怪，这是因为白术和附子共同作用于皮肤，驱逐水气尚未完全排除，所以导致这种现象。
风湿相互搏结，骨节疼痛烦扰，牵拉样疼痛不能屈伸，触碰则疼痛剧烈，出汗、短气、小便不利、怕风不想脱掉被子，或者伴有轻微浮肿的，由甘草附子汤主治。
附子（二枚）、白术（二两）、桂枝（三两）、甘草（二两）。
切碎，用水三升，煮取一升，滤去药渣，分三次温服。如果身体浮肿，加防己二两；如果心悸、小便不利，加茯苓一两半，加水总量至四升，煎取一升三合。
Taiyang disease (Disease of the Taiyang channel), characterized by joint pain and irritability, with a deep and slow pulse, is a sign of Bi syndrome due to dampness. If the patient has difficulty urinating and loose stools, treatment should focus on promoting urination; Wuling San (Five-Ingredient Powder with Poria) is indicated. (The formula is recorded in the section on "Water Retention Patterns".)
Patients suffering from dampness typically present with body ache, fever, and a sallow complexion resembling smoke-staining (body like smoked yellow). In such cases, it is still treated as wind-dampness. If the pulse is floating, the body feels heavy, there is sweating, and aversion to wind, Fangji Huangqi Tang (Astragalus and Stephania Decoction) is indicated.
Fangji (Stephaniae Tetrandrae Radix, 2.5 liang), Huangqi (Astragali Radix, 2.5 liang), Gancao (Glycyrrhizae Radix et Rhizoma, 1 liang), Baizhu (Atractylodis Macrocephalae Rhizoma, 1.5 liang), Shengjiang (Zingiberis Rhizoma Recens, 1.5 liang), Dazao (Jujubae Fructus, 16 pieces).
Crush the herbs, add four sheng of water, decoct until two sheng remain, remove the dregs, and drink one cup warm. Take again after some time post-meal. For asthma, add Mahuang (Ephedrae Herba, 1 liang); for stomach disharmony, add Shaoyao (Paeoniae Radix Alba, 1.5 liang); for qi rushing upward, add Guizhi (Cinnamomi Ramulus, 1.5 liang); for chronic cold below, add Xixin (Asari Radix et Rhizoma, 1 liang). After taking the medicine, a sensation of insects crawling under the skin may occur. If the area below the waist feels cold as ice, sit on thick blankets and wrap another blanket around the lower body to induce slight sweating.
In patients with dampness, if only the head sweats, the back is stiff, and they desire to be covered and near fire: premature purgation leads to hiccups, chest fullness, difficulty urinating, and a tongue coating resembling moss. This indicates heat in the lower dantian and cold in the upper chest, causing thirst for water but inability to drink due to dry mouth.
If purgation is incorrectly used in dampness patients, resulting in sweat on the forehead, slight asthma, and difficulty urinating, the prognosis is fatal. Similarly, persistent diarrhea is fatal.
Question: When wind and dampness contend, causing whole-body pain, perspiration should resolve it. However, during continuous rainy weather, if pain recurs after sweating, why? Answer: Excessive sweating removes only the wind, leaving the dampness behind, hence no cure. To treat wind-dampness, induce only slight sweating so that both wind and dampness are expelled.
For dampness patients with body pain, fever, yellowish face, asthma, headache, nasal congestion, and irritability, with a large pulse, normal appetite, and a harmonious abdomen, the pathology is cold-dampness in the head causing nasal congestion. Finely powder Gengti (Thladianthae Fructus), place a small amount in the nose with water to cure.
For dampness patients with body discomfort and pain, Mahuang Tang (Ephedra Decoction) with added Baizhu (Atractylodis Macrocephalae Rhizoma, 2 liang) can be used. (Mahuang Tang is recorded in the section on "Sweating Patterns".)
When a patient has whole-body pain, fever, and worsening symptoms in the late afternoon, this is named Wind-Dampness. This condition arises from exposure to wind while sweating or long-term exposure to cold. Xingren Yiyi Tang (Apricot Seed and Coix Decoction) is indicated.
Mahuang (Ephedrae Herba, 1.5 liang), Xingren (Armeniacae Semen Amarum, 45 seeds), Yiyiren (Coicis Semen, 0.5 liang), Gancao (Glycyrrhizae Radix et Rhizoma, 0.5 liang).
Crush, add two sheng of water, first boil Mahuang for 10-20 boils, skim off the foam, add other herbs, decoct to one sheng, remove dregs, and take warm in two or three doses.
After eight or nine days of Cold Damage (Shanghan), if wind and dampness contend, causing bodily pain and irritability, inability to turn over, no vomiting or thirst, and a floating, deficient, and choppy pulse, Guizhi Fuzi Tang (Cinnamon Twig and Aconite Decoction) is indicated.
This treats cases with spontaneous loose stools and difficulty urinating.
Guizhi (Cinnamomi Ramulus, 2 liang), Fuzi (Aconiti Lateralis Radix Praeparata, 2 pieces), Shengjiang (Zingiberis Rhizoma Recens, 1.5 liang), Dazao (Jujubae Fructus, 12 pieces), Gancao (Glycyrrhizae Radix et Rhizoma, 1 liang).
Crush, add three sheng of water, decoct to one sheng, remove dregs, and divide into four warm doses. If stools are hard and urination is free, remove Guizhi and add Baizhu (Atractylodis Macrocephalae Rhizoma, 2 liang), decocting as before. After the first one or two doses, the body may feel numb; finish all doses within half an hour. The patient may feel dizzy; do not be alarmed, as this is due to Baizhu and Fuzi acting together on the skin to expel water qi which has not yet been fully removed.
When wind and dampness contend, causing bone and joint pain and irritability, pulling pain preventing flexion and extension, severe pain upon touch, sweating, shortness of breath, difficulty urinating, aversion to wind with reluctance to remove covers, or slight swelling, Gancao Fuzi Tang (Licorice and Aconite Decoction) is the primary treatment.
Fuzi (Aconiti Lateralis Radix Praeparata, 2 pieces), Baizhu (Atractylodis Macrocephalae Rhizoma, 2 liang), Guizhi (Cinnamomi Ramulus, 3 liang), Gancao (Glycyrrhizae Radix et Rhizoma, 2 liang).
Crush, add three sheng of water, decoct to one sheng, remove dregs, and divide into three warm doses. For body swelling, add Fangji (Stephaniae Tetrandrae Radix, 2 liang); for palpitations and difficulty urinating, add Fuling (Poria, 1.5 liang), increasing water to four sheng and decocting to one sheng and three he.
