Jia Zhen Sun said: Dampness is the qi transformation of Earth. Fire-heat can generate damp-Earth; therefore, in summer heat, all things are moist, and in autumn coolness, all things are dry. Damp diseases do not arise spontaneously but are caused by heat causing stagnation (Qi stagnation), preventing the normal dissemination and flow of water passages, thus leading to stagnation and the generation of dampness. Moreover, individuals with fragile Spleen-Earth are prone to external pathogenic invasions; must water flow stagnate before it is considered damp? People only know the majesty and severity of Wind-Cold but do not realize the insidious harm of Summerheat-Dampness. The *Bing Shi* states: Various conditions such as stiffness and rigidity, and fluid retention belong to Dampness. If there is body swelling, aversion to cold, and presence of water qi, internally there must be scanty, dark, or obstructed urination, or thirst. This indicates that accumulated heat has penetrated deeply into the interior; it is not a Cold disease. Generally, the treatment principle should prioritize regulating the Spleen, clearing heat, and promoting diuresis. Therefore, treating dampness without promoting urination is incorrect. Suitable treatments include Guiling Ganlu San (Cassia Twig and Poria Decoction), Muxiang (Aucklandiae Radix), Tinglizi (Descurainiae Semen), and Mutong (Akebiae Caulis). Shouzhen Teacher stated: Taking Tingli Muxiang San (Descurainia and Aucklandia Powder) combined with Shenxiong Wan (Divine Angelica Pill) effectively moves downward water-dampness, reduces swelling, promotes urination, and regulates the Spleen and Stomach; nothing surpasses this. For severe abdominal distension and leg edema, Zhouche Wan (Boat Cart Pill) should be used to purge. For deep internal damp-heat causing jaundice, Yinchen Tang (Artemisia Decoction) should be used, possibly assisted by Fangji (Stephaniae Radix) and Huangqi (Astragali Radix). If the entire body is swollen and painful, or if there is no sweating, this indicates dampness flowing into the joints with pathogenic factors at the exterior. Wuling San (Five-Poria Decoction) added with Guigui (Cinnamomi Ramulus) and Cangzhu (Atractylodis Rhizoma) should be used to induce slight sweating; profuse sweating must be avoided. If spontaneous sweating is excessive, drying heat damages body fluids, and internal water metabolism is impaired, diuretics must absolutely not be used, as this would severely damage body fluids. Instead, Fangfeng Baizhu Gancao Tang (Saposhnikovia, Atractylodes, and Licorice Decoction) should be administered. There are two types of dampness syndromes: damp-heat is common, while damp-cold is rare; they must be distinguished by pulse and symptoms. For example, a slippery and rapid pulse, dark and difficult urination, and increased thirst indicate a damp-heat syndrome; conversely, free and clear urination, loose stools, body pain, and spontaneous sweating indicate a cold-damp syndrome. Treatment should use Wuling San added with Sheng Fuzi (Raw Aconiti Lateralis Radix), Cangzhu, and Mugua (Chaenomelis Fructus).
Fangji Huangqi Tang (Formula from *Jin Gui Yao Lue*) treats Wind-Dampness with floating pulse, heavy body, sweating, aversion to wind, or pain with weakness.
Fangji (1 liang), Gancao (Honey-fried, 0.5 liang), Baizhu (7.5 qian), Huangqi (1 liang).
Crush the herbs. Take 1 liang per dose, decoct with Ginger and Jujube. For asthma, add Mahuang (Ephedrae Herba); for disharmony of Stomach Qi, add Shaoyao (Paeoniae Radix); for rebellious Qi rising, add Guizhi (Cinnamomi Ramulus); for cold below, add Xixin (Asari Radix et Rhizoma).
Note: Excess dampness causes heaviness; Wei Yang deficiency with Wind invasion causes sweating and aversion to wind. Thus, Huangqi and Gancao are used to secure the exterior, while Fangji and Baizhu overcome dampness. These are typical herbs for the Three Yin channels of the Foot.
Wuji San (Formula from *Tai Ping Hui Min He Ji Ju Fang*) treats external contraction of Wind-Cold and exposure to Cold-Dampness resulting in heavy and painful body. (See Cold Category.)
Note: Haizang said: Mahuang, Guizhi, Shaoyao, and Gancao constitute Mahuang Guizhi Ban Xia Tang (Half-and-Half Decoction of Ephedra and Cinnamon Twig); Cangzhu, Gancao, Chenpi, and Houpo constitute Pingwei San (Stomach-Ping Powder); Zhike, Jiegeng, Chenpi, Fuling, and Banxia constitute Jiegeng Banxia Tang (Platycodon and Pinellia Decoction). Additionally, Chuanxiong and Danggui treat Blood, while Ganjiang and Houpo disperse Qi. The combination of these herbs forms a formula for releasing the exterior, warming the middle, and draining dampness, resolving phlegm, eliminating fullness, and regulating menstruation. Although it addresses internal cold and external contraction, constrained by the distinction between exterior and interior, it is not strictly Zhang Zhongjing's definitive formula for exterior-interior conditions using Mahuang, Guizhi, Jiang, and Fu Zi. Regarding accumulation of cold with vomiting and diarrhea, epidemic neck and back stiffness, such as Congbai (Scallion White) and Douchi (Fermented Soybean); for cold extremities, add Wuzhuyu (Evodiae Fructus); for alternating chills and fever with cough and rebellion, add Zao (Jujube); for women postpartum, add Vinegar. One realizes its application is not monolithic; only those who understand flexible methods should select it.
Shenshi Tang (Formula from *Tai Ping Hui Min He Ji Ju Fang*) treats injury by Cold-Dampness, characterized by heavy body, cold waist feeling like sitting in water, dysuria, or loose stools. This is caused by sitting or lying on wet ground or being attacked by rainy weather.

Yinchenhao (Artemisiae Scopariae Herba) (10 parts), Wuling San (5 parts).
Mix the two powders evenly and decoct with water for oral administration.

Grind into powder, make pills with drops of water, size of small beans. Start with 5 pills, increase by 5 pills per dose, take with warm water, anytime, three times daily.
Pingwei San (Formula from *Tai Ping Hui Min He Ji Ju Fang*) treats disharmony of Spleen and Stomach with poor appetite. Regular use warms the stomach and resolves phlegm.
Cangzhu (Soaked in rice wash water, 5 jin), Houpo (Magnoliae Officinalis Cortex, ginger-processed, fried), Chenpi (Citri Reticulatae Pericarpium) (each 3 jin 2 liang), Gancao (Licorice Root, fried, 30 liang).
Grind into powder. Take 5 qian per dose with 3 slices of Ginger and 1 Jujube, decoct and drink. Adding a pinch of salt and taking with boiling water is also acceptable. Another prescription adds Caoguo (Tsaoko Fructus), named Pingwei Caoguo San.
Shengyang Chushi Tang (Li Dongyuan's Formula).
Shengyang Chushi Fangfeng Tang (Li Dongyuan's Formula. Both seen in Diarrhea Section.)
Zhujiu Yingxiao Fang (Effective Boiled Wine Prescription) treats various dampness conditions and bone-joint pain. (Formula seen in Wind Section.)
Mishou Xianfang Wanying Gao (Secretly Transmitted Immortal Ten-Thousand-Effect Plaster) applies to all dampness invading muscles and entering bones/joints with intermittent pain; applying it yields miraculous effects. (Formula seen in Carbuncle and Jaundice Section.)
Shenxiong Daoshui Wan treats internal depression of damp-heat, chest and diaphragm fullness, nasal obstruction or epistaxis, mouth and tongue ulcers, throat discomfort, gum decay, tooth erosion, bad breath, or generalized damp sores and dry scabies, sleep-talking, bruxism, palpitations, constipation or difficult urination, and conditions such as wind-heat, alcohol toxicity, and accumulated heat.
