伤寒病后出现的“阴阳易”这种病症。患者身体沉重，气短乏力，小腹部拘急疼痛，有时牵引到阴部出现痉挛感，热气向上冲撞胸部，头部沉重难以抬起。（大病刚刚痊愈，气血尚未恢复，体内余热未尽，此时强行进行性生活而致病的人，称为“易”。男子大病初愈身体未完全康复，与女子发生性关系导致女子患病，或女子病愈后与男子发生性关系导致男子患病，均属于此类。）
烧裈散方：
取妇人贴身内裤（中裈），靠近生殖器部位的部分，剪下后烧成灰，用水调服一方寸匕的药量。每天服用三次。服药后小便通畅，阴头轻微肿胀，即为痊愈。
大病痊愈后，因劳累而复发的“劳复”，用枳实栀子汤主治。如果伴有积食停滞，加大黄，大小如博戏用的棋子五六枚。
（疾病有劳复和食复两种。伤寒病刚痊愈，气血未平，余热未尽，过早从事体力劳动而致病的，称为“劳复”。）
枳实栀子豉汤方：
枳实（三枚，炙过，味苦性寒） 栀子（十四枚，掰开，味苦性寒） 豆豉（一升，用绵布包裹，味苦性寒）
（枳实栀子豉汤本应是催吐的药剂，这里说覆盖衣被使其微微出汗，是因为热邪聚集在上方，苦味药能引起呕吐；若热邪聚集在体表，则通过发汗来解除。）
先单独煮栀子，再纳入其他药物。
伤寒病痊愈后，再次出现发热的，用小柴胡汤主治。脉象浮的，用发汗法解除表邪；脉象沉实的，用泻下法解除里实。
（病愈后，余热未尽，再次发热，给予小柴胡汤以和解少阳。脉浮，说明热邪在表，所以用发汗法。脉沉实，说明热邪在里，所以用泻下法。）
大病痊愈后，腰部以下有水气停留（浮肿）的，用牡蛎泽泻散主治。
（大病痊愈后，脾胃气虚，不能制约肾水，水湿泛滥于下焦，导致腰部以下浮肿。《金匮要略》说：腰部以下肿……）
牡蛎泽泻散方：
牡蛎（咸味，性平，熬制） 泽泻（咸味，性寒） 栝楼根（苦味，性寒） 蜀漆（辛味，性平，洗去腥味） 葶苈子（苦味，性寒，熬制） 商陆根（咸味，涌泄作用，牡蛎、泽泻、海藻等咸味药，用来泄除水气。《内经》说：湿气内盛，用苦味药平治，佐以酸辛味药。）
以上七味药，捣筛为散，白米汤送服方寸匕，每日三次。
大病痊愈后，喜欢流口水，长时间不能止住的，是胃上有寒，应当用丸药温补，适宜用理中丸。
（发汗后阳气不足，胃中虚寒，不能收纳津液，所以喜欢流口水且久不愈。给予理中丸，以温暖胃部。）
伤寒病解之后，身体虚弱消瘦，气短乏力，气逆想呕吐的，用竹叶石膏汤主治。
（伤寒病解之后，津液不足导致身体虚弱消瘦，余热未尽。热邪伤气，所以气短。气机上逆想呕吐。给予竹叶石膏汤。）
竹叶石膏汤方：
竹叶（二把，辛味，性平） 石膏（一斤，甘味，性寒） 半夏（半升，洗过，辛味，性温） 麦门冬（一升，甘味，性平，去心） 人参（三两，甘味，性微温） 甘草（二两，炙，甘味，性平） 粳米（半升，甘味，性平）
（辛甘发散以清除余热。竹叶、石膏、甘草的甘辛之性，用来发散余热。甘味缓和脾气并益气。麦门冬滋养阴液。以上七味药，用水一斗，煮取六升，去渣，加入粳米，煮至米熟，汤成，去米，每次温服一升，每天三次。）
病患的脉象已经平和正常，但到了傍晚时分感到轻微烦闷，这是因为病刚痊愈，人勉强进食过多，脾胃之气尚弱，不能消化食物，所以导致轻微烦闷。减少饮食量就会痊愈。
（阳明经气旺于申、酉、戌时，宿食停留在胃中，所以傍晚时分轻微烦闷。应当攻下宿食，通过减少谷物摄入来治疗。）
The disease known as "Yin-Yang Yi" (Exchange of Yin and Yang) following Shaoyang syndrome. The patient experiences heavy body sensation, shortness of breath (Shaoqi), urgency and tension in the lower abdomen, sometimes with spasms drawing into the genital region, heat rushing up to the chest, heaviness of the head making it difficult to lift. (After a major illness has just healed, blood and Qi have not yet recovered, and residual heat remains. If one engages in sexual intercourse forcibly and contracts this disease, it is called "Yi". When a man's illness has newly healed but he is not fully restored, and he interacts sexually with a woman causing her to fall ill, or vice versa, it falls under this category.)
Formula for Burned Underwear Powder (Shao Kun San):
Take the inner garment (Zhongkun) of a woman, cut off the part near the genital area, burn it to ash, mix with water, and administer one cubic-inch spoonful (Fangcunbi). Take three times a day. Once urination becomes smooth and the glans penis swells slightly, the patient will be cured.
For "Lao Fu" (Relapse due to Overexertion) after a major illness has healed, Zhi Shi Zhi Zi Tang (Bitter Orange and Gardenia Decoction) is the primary treatment. If there is retained food stagnation, add Da Huang (Rhubarb Root), five or six pieces the size of a Go stone.
(There are two types of relapse: Lao Fu and Shi Fu. After Shaoyang syndrome has newly healed, blood and Qi are not yet balanced, and residual heat remains. Falling ill due to early physical labor is called "Lao Fu".)
Formula for Zhi Shi Zhi Zi Chi Tang (Bitter Orange, Gardenia, and Fermented Soybean Decoction):
Zhi Shi (Immature Bitter Orange, three pieces, roasted, bitter, cold) Zhi Zi (Gardenia Fruit, fourteen pieces, broken open, bitter, cold) Chi (Prepared Soybean, one sheng, wrapped in silk, bitter, cold)
(Zhi Shi Zhi Zi Chi Tang should theoretically be an emetic agent. Here, covering the patient to induce slight sweating is because the heat is gathered above; bitter substances induce vomiting. If heat is gathered at the exterior, sweating resolves it.)
Boil Zhi Zi and Zhi Zi separately first, then add other herbs.
After Shaoyang syndrome has resolved, if fever recurs, Xiao Chai Hu Tang (Minor Bupleurum Decoction) is the primary treatment. If the pulse is floating, resolve it by inducing sweating. If the pulse is deep and solid, resolve it by purging.
(After healing, if residual heat remains and fever recurs, give Xiao Chai Hu Tang to harmonize. A floating pulse indicates heat at the exterior, hence use sweating. A deep-solid pulse indicates heat at the interior, hence use purging.)
After a major illness has healed, if there is water qi accumulation (edema) from the waist down, Mu Li Ze Xie San (Oyster Shell and Alisma Powder) is the primary treatment.
(After a major illness heals, Spleen and Stomach Qi is deficient, unable to control Kidney water. Water overflows into the Lower Jiao, causing swelling below the waist. The Jingui Yaolue states: Swelling below the waist...)
Formula for Mu Li Ze Xie San (Oyster Shell and Alisma Powder):
Mu Li (Oyster Shell, salty, neutral, roasted) Ze Xie (Alisma Rhizome, salty, cold) Gua Lou Gen (Trichosanthes Root, bitter, cold) Shu Qi (Periploca Root Bark, acrid, neutral, washed to remove fishy smell) Ting Li (Descurainia Seed, bitter, cold, roasted) Shang Lu Gen (Phytolacca Root, salty, promoting upward movement and draining)
(Salty flavors promote upward movement and drainage. The salty nature of Mu Li, Ze Xie, and Hai Zao drains water qi. The Neijing states: When dampness abounds internally, treat it with bitter flavors, assisted by sour and acrid flavors.)
Grind the above seven ingredients into powder. Administer one Fangcunbi with rice soup, three times a day.
After a major illness has healed, if the patient frequently drools and cannot stop for a long time, it is due to Cold in the Stomach. One should use pill medicine to warm it; Li Zhong Wan (Regulate the Middle Pill) is suitable.
(After sweating, Yang Qi is insufficient, leading to deficiency-cold in the Stomach, which fails to receive fluids, hence frequent drooling that persists. Give Li Zhong Wan to warm the Stomach.)
After Shaoyang syndrome has resolved, if the patient is weak and emaciated, has shortness of breath, and feels nausea with rebellious Qi, Zhu Ye Shi Gao Tang (Bamboo Leaf and Gypsum Decoction) is the primary treatment.
(After Shaoyang syndrome resolves, fluid deficiency leads to weakness and emaciation, and residual heat remains. Heat injures Qi, causing shortness of breath. Rebellious Qi causes nausea. Give Zhu Ye Shi Gao Tang.)
Formula for Zhu Ye Shi Gao Tang (Bamboo Leaf and Gypsum Decoction):
Zhu Ye (Bamboo Leaves, two handfuls, acrid, neutral) Shi Gao (Gypsum Fibrosum, one jin, sweet, cold) Ban Xia (Pinellia Tuber, half sheng, washed, acrid, warm) Mai Men Dong (Ophiopogon Tuber, one sheng, sweet, neutral, heart removed) Ren Shen (Ginseng Root, three liang, sweet, slightly warm) Gan Cao (Licorice Root, two liang, roasted, sweet, neutral) Jing Mi (Rice Grain, half sheng, sweet, neutral)
(Acrid and sweet disperse and eliminate heat. The sweet and acrid nature of Zhu Ye, Shi Gao, and Gan Cao disperses residual heat. Sweet flavors soothe the Spleen and tonify Qi. Mai Men Dong nourishes Yin. Boil the above seven ingredients in ten dou of water, reduce to six sheng, remove dregs, add Jing Mi, cook until rice is done, remove rice, take one sheng warm, three times a day.)
If the patient's pulse has normalized but they experience slight irritability towards dusk, it is because the illness has newly healed, and people force them to eat too much. The Spleen and Stomach Qi is still weak and cannot digest the food, thus causing slight irritability. Reducing food intake will lead to recovery.
(The Yangming channel is prosperous during Shen, You, and Xu hours. Retained food in the Stomach causes slight irritability at dusk. It should be purged by reducing grain intake.)
