张司农曾说，暑邪的危害比寒邪更严重，因此撰写了《暑症全书》以济世救人。但我认为，湿邪的危害，甚至比暑邪更为严重。因为在盛夏酷暑之时，必然兼夹湿气；而在湿气盛行之时，却不一定会兼夹暑气。暑邪致病，只从外部侵入；而湿邪则内外兼受。暑邪致病，发病急骤且症状明显；湿邪致病，起病缓慢且难以察觉。凡是居住在沼泽水乡地区的人，对于湿证尤其应当仔细诊察。
如果是外感湿邪，停留在肌表的，有的是从雨雾中感受到的，有的是从地面潮湿环境中感受到的，有的从上焦受邪，有的从下焦受邪，有的全身均匀受邪，都应当采用解肌法，使其微微出汗来治疗。如果兼夹风邪，用轻微的发散方法；如果兼夹寒邪，配合温性药物；如果兼夹热邪，配合清热药物。这是对外受湿邪的治疗方法。
如果是内生之湿，留滞在脏腑的，多是从饮食中得来的。凡是肥甘厚味、美酒甜浆，以及嗜好喝茶、吃瓜果等习惯，都会导致内湿。治疗方法不外乎上焦宣开肺气，下焦通利膀胱，中焦调理脾阳。然而，阳气偏盛的体质容易形成湿火，阴气偏盛的体质容易患寒湿，又应当根据患者体质的阴阳属性来治疗。用药的原则，应当用苦辛寒的药物来治疗湿热，用苦辛温的药物来治疗寒湿，一概辅以淡渗利湿的药物。甘酸滋腻浑浊的药物，都在禁用之列。在前面太阴新法中，已经陈述了湿邪的大概情况，这里特别参详湿邪的兼夹病症，并按照表里、三焦进行分治。至于湿邪变幻莫测的状态，致病形式不一，应当在杂病各门类中去寻求治疗方法即可。
脾虚之人容易中湿。全身疼痛是湿邪的表现，有在表、在里的区别，有湿热、寒湿、风湿的不同。
湿痹：痹，是指痹阻着滞不去。医论说：太阳病，关节疼痛且烦躁，脉象沉而细的，这名叫中湿，也叫湿痹。其症状是小便不利，大便反而通畅，只应当利小便。此证适宜用五苓散主治。如果出现发黄，加茵陈。
风湿：病人全身疼痛，发热，在下午申时（日晡）加剧的，这名叫风湿。这种病是因为出汗时当风受凉，或久处冷湿环境所致。可以用麻黄杏仁薏苡甘草汤。又说，风湿病脉浮，身体沉重，出汗且怕风的，用防己黄芪汤主治。
风湿相搏：全身剧烈疼痛，按理应当通过发汗而解除。如果遇到阴雨连绵天气不止，医生说此病可以发汗，发汗后病却未愈，为什么呢？因为发汗时汗出太多，只去了风气，湿气仍在，所以不愈。如果要治疗风湿，发汗时只要微微似有汗出的样子，风湿就能一起去除。
头中寒湿：患湿病的人，身体疼痛发热，面色发黄且气喘，头痛，鼻塞且心烦，脉象大，能正常饮食，腹部平和无病。病位在头中的寒湿，所以鼻塞。将药纳入鼻中即可痊愈。用香瓜蒂一味研为末，吹入鼻中，流出黄水立刻痊愈。
湿家误用下法：额头出汗，微喘，小便通利的，主死。如果下利不止的，也主死。（以上引述自《金匮要略》）
表湿：关节疼痛，脉浮而濡软，四肢痿弱无力，这是湿邪在表。小便通利的，用桂枝汤加川羌活、白术等，微汗之。小便不利的，用五苓散加减。
中湿：如果关节沉重疼痛，浮肿气喘胸闷，腹胀烦闷，昏迷不知人事，脉象沉而缓，或沉而细，这名叫中湿。适宜用升阳除湿汤，或白术酒。
破伤湿：有破损伤口处，因洗澡，湿气从疮口进入体内。其人昏迷沉重，症状类似中湿，名叫破伤湿。适宜用白术酒。
湿热：脉象濡细而数，发热身痛，小便短少涩滞，或身体面目俱黄，属于湿热。适宜用五苓散，加生栀子、黄柏、茵陈、秦艽。
寒湿：脉象沉迟而濡，身体无热，只是呕吐腹泻，口不渴，小便清长，身体疼痛重着，或手足肿痛，这是寒湿。适宜分利渗湿兼温中。用胃苓汤加炮姜、木瓜。重症加附子。按医论所说，湿家病人，只有头部出汗，背部强直，想要盖被子靠近火源的，这是寒湿。又说，伤寒八九日，风湿相搏，身体疼痛，不能自行转侧，不呕不渴，脉浮虚而涩的，用桂枝附子汤主治。这也是风湿兼寒。
风湿：脉浮身重，不能转侧，自汗，或额头多汗，这是先伤于湿，又冒受风邪所致。适宜微汗之，渍渍然似有汗出的样子，风湿就能一起去除。用大羌活汤。
湿痰：脉象沉缓而滑，四肢游走疼痛，或项背强直，常见于肥胖之人，属于湿痰。适宜二陈汤、二术、桂枝、羌活等加减。
脾胃受湿，就会沉重困倦无力，怠惰嗜睡，必须以苍术、白术为君药。上部湿邪，苍术最烈；下部湿邪，用升麻提举。外湿宜表散，内湿宜渗泄。湿盛身痛，用羌活胜湿汤、平胃散之类。风湿相搏，全身疼痛，自汗的，用防己黄芪汤。湿盛身痛，小便不利，体重发渴的，用五苓散加一倍量的川羌活，煎服效果妙。（以上诸条参考《治法汇》）
湿着肌表：如发热身痛，脘腹闷胀不渴，舌苔白腻，或出汗后病不解，这是湿邪附着于肌躯之表。适宜解肌渗湿。如桂枝、秦艽、紫苏、二陈汤、浓朴、姜皮、茯苓皮之类。
湿留气分：凡发热身痛，出汗后缓解，继而再次发热，脉来濡缓，舌苔白腻，这是湿邪阻滞于气分，热自湿中生发，单纯使用清热药无效。适宜用茯苓皮、大腹皮、滑石粉、黄芩、通草、半夏、猪苓之类，以祛除气分之湿，热自然消除。
太阴湿伏：凡身体沉重，不能转侧，四肢乍冷，目黄脘痞，自利，语言欲蹇涩者，这是湿邪伏于太阴，导致脾阳不运而如此。适宜健脾兼分利。用茅术、浓朴、茯苓皮、草蔻、菖蒲、广皮、木瓜、泽泻之类。如果口内生白疳，仍然不渴的，这是湿滞于中，气蒸于上。治疗在气分，用茅术、米仁、猪苓、泽泻、广皮、桔梗、寒水石之类。如果痞结胸满，饮食不进，舌黄微渴，这是湿热伤脾。适宜用泻心法。用半夏、茯苓、川连、浓朴、茅术、通草。
湿热内结：如寒热交替，腹满，小便不利，这是湿热内结。适宜走湿清热。用茅术、赤小豆、茵陈、茯苓皮、浓朴、黄柏、泽泻之类。
酒湿伤胃：脘中食物阻滞，疼痛而呕吐，或目色金黄，这是酒湿伤胃所致。适宜以苦辛寒为治。用半夏、枳实、姜汁、黄连、豆豉、茵陈之类。
湿兼痧秽：秽湿从口鼻吸入，则膜原先受邪，分布营卫，先呕吐逆乱，次寒热，头胀身痛，小便不通，舌苔白腻，渴但不多饮。当以芳香淡渗兼施，使秽湿浊邪可以分消。适宜用广皮、藿梗、郁金、茅术、米仁、茯苓皮、猪苓、大腹皮、石菖蒲、通草。
湿热兼秽：暑湿兼秽气，都从口鼻触入，必由膜原以走中道，踞募原，则寒热交作；走中道，则不食不饥，口渴舌黄，胸痞腹胀。治疗适宜清热开郁，兼芳香逐秽。用栀豉汤，加藿香、川郁金、白蔻、枳实、制连、蒌皮、桔梗之类。如果小便不利，加赤小豆、赤茯苓之类。腹胀甚，加浓朴、大腹皮。
湿热为痹：外受湿热之邪，内进甜腻之物，则湿聚热蒸，蕴于经络，寒战热炽，骨骱烦疼，舌苔灰腻，面目痿黄，这是湿热入于经络为痹。湿家忌汗，适宜苦味辛通为治。用防己、杏仁、滑石、半夏、米仁、连翘、山栀、野赤豆皮、路路通之类。更有暑湿风邪混杂，阻于气分，气不主宣，右肢若废，头胀胸痞，法当通阳驱邪。
处方：杏仁（三钱）、生米仁（三钱）、桂枝（五分）、浓朴（一钱）、半夏（一钱五分）、汉防己（一钱五分）、白蒺藜（二钱）、片姜黄（一钱）。
三焦湿郁：发热后，神识逐渐昏蒙，小腹硬满，大便不下，这是暑湿气蒸，弥漫三焦，乃诸窍阻塞之兆。气分结邪，忌用滋腻。须用桂苓甘露饮法。茯苓、猪苓、滑石、寒水石、晚蚕砂、皂荚子去皮。（以上参考叶天士医案）
Zhang Sinong stated that the harm of Summerheat pathogen is more severe than that of Cold, and therefore wrote the *Complete Book of Summerheat Syndromes* to benefit the world. I, however, believe that the harm of Dampness pathogen is even more severe than that of Summerheat. This is because during the peak of Summerheat, it must be accompanied by Dampness, whereas when Dampness is prevalent, it does not necessarily accompany Summerheat. The Summerheat pathogen enters only from the exterior, while the Dampness pathogen affects both interior and exterior. Diseases caused by Summerheat appear suddenly and are easily visible; diseases caused by Dampness develop slowly and are difficult to detect. Those living in marshy or water-rich regions should pay particular attention to Dampness syndromes.
If it is exogenous Dampness lodging on the muscle layer (Muscle Layer), whether contracted from rain and fog, from damp ground air, received from above, from below, or uniformly throughout the body, one should employ the method of resolving the muscle layer to induce slight sweating. If accompanied by Wind, use mild dispersing methods; if accompanied by Cold, assist with warm herbs; if accompanied by Heat, assist with clearing herbs. This is the treatment for exogenous Dampness pathogen.
If it is endogenous Dampness remaining in the Zang-Fu organs, it usually arises from diet. Rich foods, sweet wines, sugary and greasy flavors, as well as habits of drinking tea and eating fruits, all lead to internal Dampness. The treatment methods do not exceed opening Lung Qi in the upper Jiao, unblocking the Bladder in the lower Jiao, and regulating Spleen Yang in the middle Jiao. However, constitutions with excess Yang tend to form Damp-Heat Fire, while constitutions with excess Yin tend to suffer from Cold-Dampness. One must treat according to the patient's Yin-Yang constitution. The principle of medication is to use Bitter-Pungent-Cold herbs for Damp-Heat, and Bitter-Pungent-Warm herbs for Cold-Dampness, generally assisted by bland leaching agents. Sweet, sour, greasy, and turbid substances are strictly prohibited. In the previous section on New Methods for Taiyin, the general overview of Dampness pathogen was already presented. Here, we specifically discuss the complicated syndromes of Dampness pathogen and treat them according to Exterior/Interior and the Three Jiaos. As for the变幻 (changing) nature of Dampness pathogen, which causes various diseases, one should seek treatments in the respective categories of miscellaneous diseases.
Spleen deficiency often leads to contracting Dampness. Whole-body pain is a sign of Dampness. There are distinctions between Exterior and Interior, Damp-Heat, Cold-Dampness, and Wind-Dampness.
Damp Bi (Obstruction): "Bi" refers to obstruction and stagnation that does not disperse. The medical theory states: In Taiyang disease, joint pain accompanied by irritability, with a deep and fine pulse, is named Zhong Shi (Striking Dampness), also called Damp Bi. Its symptoms include difficulty in urination and loose stools. The treatment should focus on promoting urination. This syndrome is suitable for Wuling San (Five-Ingredient Powder with Poria). If jaundice appears, add Yinchen (Artemisiae Scopariae Herba).
Wind-Dampness: When a patient suffers from whole-body pain, fever, which worsens at Shen hour (3-5 PM), this is named Wind-Dampness. This condition results from sweating followed by exposure to wind, or prolonged exposure to cold and dampness. Mahuang Xingren Yiyi Ren Gancao Tang (Ephedra, Apricot Seed, Coix Seed, and Licorice Decoction) can be used. It is also stated that for Wind-Dampness with a floating pulse, heavy body, sweating, and aversion to wind, Fangji Huangqi Tang (Stephania and Astragalus Decoction) is indicated.
Wind-Dampness Combining: Whole-body severe pain should theoretically resolve through sweating. If it coincides with continuous rainy weather, and the physician advises sweating but the disease does not improve, why? Because excessive sweating removes only the Wind, leaving the Dampness behind, hence no improvement. To treat Wind-Dampness, sweating should be induced so that there is merely a slight, continuous perspiration; then both Wind and Dampness will be expelled.
Cold-Dampness in the Head: Patients with Dampness disease may experience body pain, fever, yellowish complexion, asthma, headache, nasal congestion, and irritability, with a large pulse. They can eat normally, and the abdomen is peaceful without pathology. The disease lies in Cold-Dampness in the head, causing nasal congestion. Inserting medicine into the nose cures it. Use Xiang Gua Di (Melon Seed) alone, powdered, and insufflated into the nose. Yellow discharge appearing immediately indicates cure.
Downward purging in Dampness patients: Sweating on the forehead, slight asthma, and free urination indicate death. If diarrhea persists uncontrollably, it also indicates death. (Above quoted from *Jin Gui Yao Lue*)
Exterior Dampness: Joint pain, floating and soft pulse, flaccidity and weakness of limbs indicate Dampness in the Exterior. With free urination, Guizhi Tang (Cinnamon Twig Decoction) plus Chuan Qianghuo (Notopterygii Rhizoma et Radix) and Baizhu (Atractylodis Macrocephalae Rhizoma) is used to induce slight sweating. With impaired urination, Wuling San (Five-Ingredient Powder with Poria) is modified.
Zhong Shi (Striking Dampness): If joints are heavy and painful, edema, asthma, chest fullness, abdominal distension, irritability, coma, and unconsciousness occur, with a deep-slow or deep-fine pulse, this is named Zhong Shi. Shengyang Chushi Tang (Ascending Yang and Expelling Dampness Decoction) or Baizhu Wine is suitable.
Traumatic Dampness: At the site of a wound, bathing allows Dampness to enter through the sore. The patient becomes comatose and heavy, resembling Zhong Shi, named Traumatic Dampness. Baizhu Wine is suitable.
Damp-Heat: A soft, fine, and rapid pulse, fever, body pain, short and scanty urine, or yellowing of body and eyes belong to Damp-Heat. Wuling San (Five-Ingredient Powder with Poria) plus Sheng Zhizi (Gardeniae Fructus), Huangbai (Phellodendri Cortex), Yinchen (Artemisiae Scopariae Herba), and Qinjiao (Gentianae Macrophyllae Radix) is indicated.
Cold-Dampness: A deep, slow, and soft pulse, absence of fever, only vomiting and diarrhea, no thirst, clear and abundant urine, heavy body pain, or swelling and pain in hands and feet indicate Cold-Dampness. Treatment involves separating and leaching combined with warming the middle. Weiling Tang (Stomach Regulating Decoction) plus Pa Jiang (Prepared Ginger) and Mugua (Chaenomelis Fructus) is used. For severe cases, Fuzi (Aconiti Lateralis Radix Praeparata) is added. According to the discussion, Dampness patients who only sweat on the head, have a stiff back, and desire covering themselves near fire suffer from Cold-Dampness. Also, after eight or nine days of Cold Damage, Wind-Dampness combines, causing body pain, inability to turn independently, no vomiting or thirst, and a floating, deficient, and choppy pulse. Guizhi Fuzi Tang (Cinnamon Twig and Prepared Aconite Decoction) is indicated. This is also Wind-Dampness combined with Cold.
Wind-Dampness: Floating pulse, heavy body, inability to turn, spontaneous sweating, or excessive sweating on the forehead result from initial Dampness injury followed by Wind exposure. Mild sweating is required; a slight, continuous perspiration expels both Wind and Dampness. Da Qianghuo Tang (Great Notopterygium Decoction) is used.
Damp-Phlegm: A deep-slow and slippery pulse, wandering pain in limbs, or stiffness in neck and back, commonly seen in obese individuals, belongs to Damp-Phlegm. Er Chen Tang (Two-Aged Decoction) combined with Er Zhu (two types of Atractylodes), Guizhi (Cinnamon Twig), and Qianghuo (Notopterygii Rhizoma et Radix) is modified.
When Spleen and Stomach are affected by Dampness, there is heaviness, fatigue, weakness, lethargy, and sleepiness. Cangzhu (Atractylodis Rhizoma) and Baizhu (Atractylodis Macrocephalae Rhizoma) should be the chief herbs. For upper Jiao Dampness, Cangzhu is most potent; for lower Jiao Dampness, Shengma (Cimicifugae Rhizoma) lifts it. Exterior Dampness should be dispersed via the exterior; Internal Dampness should be leached. For Dampness-induced body pain, Qianghuo Shengshi Tang (Notopterygium Decoction for Overcoming Dampness) or Pingwei San (Regulate the Stomach Powder) are used. For Wind-Dampness combining with whole-body pain and sweating, Fangji Huangqi Tang (Stephania and Astragalus Decoction) is used. For Dampness-induced body pain, impaired urination, heavy body, and thirst, Wuling San (Five-Ingredient Powder with Poria) with double the dose of Chuan Qianghuo (Notopterygii Rhizoma et Radix) is effective. (These items reference *Zhi Fa Hui*)
Dampness Lodging on Muscle Layer: Fever, body pain, epigastric stuffiness without thirst, white greasy tongue coating, or unresolved sweating despite diaphoresis indicates Dampness lodging on the exterior of the muscle layer. Resolve the muscle layer and leach Dampness using Guizhi (Cinnamon Twig), Qinjiao (Gentianae Macrophyllae Radix), Zisu (Perillae Folium), Er Chen Tang (Two-Aged Decoction), Houpo (Magnoliae Officinalis Cortex), Jiangpi (Zingiberis Pericarpium), and Fuling Pi (Poria Cum Woody Host).
Dampness Remaining in Qi Level: Fever and body pain that resolve with sweating but recur later, with a soft-slow pulse and white greasy tongue coating, indicate Dampness obstructing the Qi level. Heat originates from Dampness; clearing heat alone is ineffective. Use Fuling Pi (Poria Cum Woody Host), Fupi (Arecae Pericarpium), Huashi (Talcum), Huangqin (Scutellariae Radix), Tongcao (Tetrapanacis Medulla), Banxia (Pinelliae Rhizoma), and Zhuling (Polyporus) to eliminate Dampness in the Qi level, thereby removing the Heat.
Taiyin Dampness Latency: Heavy body, inability to turn, intermittent cold limbs, yellow eyes, epigastric fullness, spontaneous diarrhea, and slurred speech indicate Dampness latent in Taiyin, causing failure of Spleen Yang to transport. Strengthen Spleen and promote separation/drainage using Maoyu (Atractylodis Rhizoma), Houpo (Magnoliae Officinalis Cortex), Fuling Pi (Poria Cum Woody Host), Cao Kou (Amomi Fructus Rotundus), Changpu (Acori Tatarinowii Rhizoma), Guangpi (Citri Reticulatae Pericarpium), Mugua (Chaenomelis Fructus), and Zexie (Alismatis Rhizoma). If white patches appear in the mouth without thirst, Dampness stagnates in the middle, steaming upwards. Treat the Qi level with Maoyu (Atractylodis Rhizoma), Yiyiren (Coicis Semen), Zhuling (Polyporus), Zexie (Alismatis Rhizoma), Guangpi (Citri Reticulatae Pericarpium), Jiegeng (Platycodonis Radix), and Hanshuishi (Halloysit Rubrum). If chest fullness and blockage occur with loss of appetite, yellow tongue coating, and slight thirst, Damp-Heat injures the Spleen. Use Xiexin Method (Drain Heart Method) with Banxia (Pinelliae Rhizoma), Fuling (Poria), Chuanlian (Coptidis Rhizoma), Houpo (Magnoliae Officinalis Cortex), Maoyu (Atractylodis Rhizoma), and Tongcao (Tetrapanacis Medulla).
Damp-Heat Internal Knotting: Alternating chills and fever, abdominal fullness, and impaired urination indicate Damp-Heat internal knotting. Promote Dampness movement and clear Heat using Maoyu (Atractylodis Rhizoma), Chixiaodou (Phaseoli Semen Rubrum), Yinchen (Artemisiae Scopariae Herba), Fuling Pi (Poria Cum Woody Host), Houpo (Magnoliae Officinalis Cortex), Huangbai (Phellodendri Cortex), and Zexie (Alismatis Rhizoma).
Wine-Dampness Injuring Stomach: Food stagnation in the epigastrium, pain with vomiting, or golden-yellow eye color indicates Wine-Dampness injuring the Stomach. Treat with Bitter-Pungent-Cold methods using Banxia (Pinelliae Rhizoma), Zhishi (Aurantii Fructus Immaturus), Jiangzhi (Zingiberis Juice), Huanglian (Coptidis Rhizoma), Douchi (Sojae Semen Preparatum), and Yinchen (Artemisiae Scopariae Herba).
Dampness Combined with Filth: Filthy Dampness inhaled through nose and mouth first affects the Membrane Source (Mo Yuan), distributing through Ying and Wei. Symptoms include initial nausea/vomiting, alternating chills and fever, head distension, body pain, urinary obstruction, and white greasy tongue coating with thirst but little desire to drink. Apply aromatic and bland-leaching methods to dissipate filthy Dampness and turbid pathogens. Use Guangpi (Citri Reticulatae Pericarpium), Huogeng (Agastaches Herba), Yujin (Curcumae Radix), Maoyu (Atractylodis Rhizoma), Yiyiren (Coicis Semen), Fuling Pi (Poria Cum Woody Host), Zhuling (Polyporus), Fupi (Arecae Pericarpium), Shichangpu (Acori Tatarinowii Rhizoma), and Tongcao (Tetrapanacis Medulla).
Damp-Heat Combined with Filth: Summer-Dampness combined with filth enters through nose and mouth, traveling via the Membrane Source to the Middle Path. Occupying the Mo Yuan causes alternating chills and fever; entering the Middle Path causes anorexia, thirst, yellow tongue, chest stuffiness, and abdominal distension. Treat with clearing Heat, opening depression, and aromatic expulsion of filth. Zhichi Tang (Gardenia and Fermented Soybean Decoction) plus Huoxiang (Pogostemonis Herba), Chuan Yujin (Curcumae Radix), Baokou (Cardamomi Fructus), Zhishi (Aurantii Fructus Immaturus), Zhilian (Prepared Coptidis Rhizoma), Loupi (Benincasae Exocarpium), and Jiegeng (Platycodonis Radix) is used. If urination is impaired, add Chixiaodou (Phaseoli Semen Rubrum) and Chifuling (Poria cum Wood). For severe abdominal distension, add Houpo (Magnoliae Officinalis Cortex) and Fupi (Arecae Pericarpium).
Damp-Heat Bi Obstruction: Exogenous Damp-Heat combined with internal intake of sweet/greasy foods causes Dampness accumulation and Heat steaming, accumulating in collaterals. Symptoms include chills, intense fever, bone/joint pain, gray greasy tongue coating, and sallow complexion. This is Damp-Heat entering collaterals causing Bi obstruction. Dampness patients should avoid sweating. Treat with Bitter-Pungent unblocking methods using Fangji (Stephaniae Tetrandrae Radix), Xingren (Armeniacae Semen Amarum), Huashi (Talcum), Banxia (Pinelliae Rhizoma), Yiyiren (Coicis Semen), Lianqiao (Forsythiae Fructus), Shanzhi (Gardeniae Fructus), Ye Chidoupi (Wild Phaseoli Semen Rubris Cuticle), and Lulutong (Liquidambaris Fructus). If Summer-Dampness-Wind pathogens mix, obstructing the Qi level, preventing Qi circulation, causing right limb paralysis, head distension, and chest stuffiness, the method is to unblock Yang and drive out pathogens.
Prescription: Xingren (3 qian), Sheng Yiyiren (3 qian), Guizhi (0.5 qian), Houpo (1 qian), Banxia (1.5 qian), Han Fangji (1.5 qian), Bai Jili (2 qian), Pian Jianghuang (1 qian).
Three Jiaos Dampness Depression: After fever, mental confusion gradually sets in, lower abdomen becomes hard and full, and defecation stops. This indicates Summer-Dampness steaming and filling the Three Jiaos, signaling obstruction of orifices. Pathogenic knots in the Qi level contraindicate cloying/nourishing herbs. Use the method of Guiling Ganlu Yin (Cassia Seed and Poria Decoction). Ingredients: Fuling (Poria), Zhuling (Polyporus), Huashi (Talcum), Hanshuishi (Halloysit Rubrum), Wancansha (Bombyx Batryticatus), and Zaopiaozi (Gleditsiae Sinensis Spina - peeled).
