Dampness disease arises when excessive dampness in the Taiyin (Spleen/Stomach channel) combines with exogenous Wind-Cold. Dampness permeates and fills the entire body; upon encountering Wind-Cold, it closes the skin pores, causing stagnation of Qi in the meridians throughout the body, thereby triggering symptoms such as pain, fever, and restlessness. When dampness invades the Upper Jiao (Upper Burner), pain occurs in the head and eyes. When dampness overflows to the lower part, pain occurs in the knees and ankles. When dampness infiltrates the Liver and Kidneys, pain occurs in the waist and abdomen. When dampness pervades the whole body, affecting interior and exterior, upper and lower, there is no place without pain, especially severe at the joints and bone crevices. Where water-dampness predominates, it transforms into Cold-Dampness. Where Fire-heat predominates, it stagnates and steams into Damp-Heat. The treatment principle is to unblock the Bladder internally and open the sweat pores externally, allowing both exterior and interior pathogens to be discharged simultaneously, thus curing the disease. For Cold-Dampness presenting with restlessness and pain worsening in the late afternoon, Yinchen Wuling San (Artemisiae Scopariae Five-Ingredient Powder) is prescribed. For Wind-Dampness combing together, causing bodily restlessness and pain preventing self-turning, without vomiting or thirst, and with a floating, deficient, and choppy pulse, Guizhi Fuzi Tang (Cinnamon Twig and Aconite Decoction) is prescribed. If the patient has hard stool and free urination, Guizhi is removed and Baizhu is added (Qu Guizhi Jia Baizhu Tang). For Wind-Dampness combing together, causing joint restlessness, pulling pain, inability to flex or extend, severe pain upon touch, sweating, shortness of breath, difficult urination, aversion to wind with reluctance to remove clothes, or slight edema, Gancao Fuzi Tang (Licorice and Aconite Decoction) is prescribed. If the patient suffers from generalized body pain and fever worsening in the late afternoon, this is named Wind-Dampness, and Mahuang Xingren Yiyi Gancao Tang (Ephedra, Apricot Seed, Coix Seed, and Licorice Decoction) is prescribed. For Damp-Warmth presenting with headache, aversion to cold, heavy painful body, white tongue coating or thirst, afternoon fever, and a floating, deficient pulse, Sanren Tang (Three-Nut Decoction) is prescribed. When excessive dampness causes Spleen stagnation and Lung congestion, generating Upper Jiao Heat, the method should clear heat and promote diuresis using Yuanhua Linggan San (Mirabilite, Talcum, Poria, and Licorice Powder). For abdominal fullness and dysuria caused by Liver Wood stagnation generating Lower Jiao Heat, the method should promote diuresis to drain Damp-Heat using Linggan Zhizi Yinchen Tang (Poria, Licorice, Gardenia, and Artemisiae Scopariae Decoction).
Yinchen Wuling San (Artemisiae Scopariae Five-Ingredient Powder)
Composed of Baizhu (Atractylodis Rhizoma), Guizhi (Cinnamomi Ramulus), Fuling (Poria), Zhuling (Polyporus), and Zexie (Alismatis Rhizoma) in equal parts, ground into powder. Take 5 qian per dose, mix with 1 liang of Yinchenhao (Artemisiae Scopariae Herba) powder, blend evenly, and take one tablespoon mixed with rice water on an empty stomach, three times daily. Drink more hot soup to induce sweating. If fever and aversion to cold occur, indicating exterior pathogen closure, add Zisu (Perillae Folium) to release the exterior.
Guizhi Fuzi Tang (Cinnamon Twig and Aconite Decoction)
Guizhi (Cinnamomi Ramulus, 4 qian), Zhi Gancao (Prepared Glycyrrhizae Radix et Rhizoma, 2 qian), Shengjiang (Zingiberis Rhizoma Recens, 3 qian), Pao Fuzi (Prepared Aconiti Lateralis Radix, 3 qian), Dazao (Jujubae Fructus, 3 pieces). Decoct in water to obtain half a cup, take warm.
Qu Guizhi Jia Baizhu Tang (Decoction with Guizhi Removed and Baizhu Added)
Gancao (Glycyrrhizae Radix et Rhizoma, 1 qian), Dazao (Jujubae Fructus, 3 pieces), Shengjiang (Zingiberis Rhizoma Recens, 3 qian), Pao Fuzi (Prepared Aconiti Lateralis Radix, 3 qian), Baizhu (Atractylodis Rhizoma, 4 qian). Decoct in water to obtain half a cup, take warm.
Gancao Fuzi Tang (Licorice and Aconite Decoction)
Zhi Gancao (Prepared Glycyrrhizae Radix et Rhizoma, 2 qian), Pao Fuzi (Prepared Aconiti Lateralis Radix, 2 qian), Baizhu (Atractylodis Rhizoma, 2 qian), Guizhi (Cinnamomi Ramulus, 4 qian). Decoct in water to obtain half a cup, take warm.
Mahuang Xingren Yiyi Gancao Tang (Ephedra, Apricot Seed, Coix Seed, and Licorice Decoction)
Mahuang (Ephedrae Herba, 2 qian), Xingren (Armeniacae Semen Amarum, 3 qian), Yiren (Coicis Semen, 3 qian), Gancao (Glycyrrhizae Radix et Rhizoma, 1 qian). Decoct in water to obtain half a cup, take warm.
Sanren Tang (Three-Nut Decoction)
Xingren (Armeniacae Semen Amarum, 3 qian), Baokouren (Amomi Fructus Rotundus, 2 qian), Sheng Yiren (Raw Coicis Semen, 3 qian), Huashi (Talcum, 3 qian), Zhuye (Bambusae Folium, 1 qian), Sangye (Mori Folium, 3 qian), Baigengtong (Akebiae Caulis, 2 qian), Banxia (Pinelliae Rhizoma, 2 qian). Decoct in Ganlan Water (water boiled up and down repeatedly) to obtain half a cup, take warm. The formula still contains warming herbs because Dampness is a Yin pathogen; without warming agents to move Qi, Dampness cannot be eliminated.
Yuanhua Linggan San (Mirabilite, Talcum, Poria, and Licorice Powder)
Yuanmingfen (Natrii Sulfas), Huashi (Talcum), Fuling (Poria), Gancao (Glycyrrhizae Radix et Rhizoma) in equal parts, ground into powder. Mix with Barley Porridge Juice and take one tablespoon, three times daily. Dampness exits via urine and stool; yellow urine and black stool are signs of this process. If dampness is in the abdomen causing Lung Qi stagnation, leading to headache, nasal congestion, hoarseness, and mental restlessness, add Chenpi (Citri Reticulatae Pericarpium) and Xingren (Armeniacae Semen Amarum) to vent Lung Qi alongside sweating and diuresis.
Linggan Zhizi Yinchen Tang (Poria, Licorice, Gardenia, and Artemisiae Scopariae Decoction)
Yinchen (Artemisiae Scopariae Herba, 3 qian), Zhizi (Gardeniae Fructus, 2 qian), Sheng Gancao (Raw Glycyrrhizae Radix et Rhizoma, 2 qian), Fuling (Poria, 3 qian). Decoct in water to obtain half a cup, take hot. After ingestion, urination should become profuse, resembling soapberry juice in color and bright red. Abdominal distension reduces overnight as dampness exits via urine. If Damp-Heat is in the Spleen, add Dahuang (Rhei Radix et Rhizoma) and Mangxiao (Natrii Sulfas). If Damp-Heat is solely in the Liver while the Spleen and Kidneys have Cold-Dampness, add Ganjiang (Zingiberis Rhizoma) and Fuzi (Aconiti Lateralis Radix Praeparata). If the Bladder lacks Heat, simply use Zhuling Tang (Polyporus Decoction) to promote diuresis.
