湿气源于脾气虚弱，无法运化水液以正常运行，水性凝滞不动，日久腐化，转而侵犯脾土，从而形成各种湿症的表现。其症状表现为面色暗白，皮肤粗糙不润泽，口唇晦暗紫绀而不红润鲜活，或者痰液容易生成但难以化解，或者饮食稍有损伤，立即发生泄泻，或者排出清水样便，或者呕吐酸腐食物，或者身体发热且容易出汗，或者四肢倦怠而头部沉重，凡此类症状表现，均属于脾湿症。治疗方法以苍术、白术为主药，加入土炒杭芍（白芍）、木瓜片、花槟榔、半夏曲、广陈皮、赤茯苓、车前草、炙甘草、乌梅等药物，加水煎煮成浓汁，趁温热服用，定能渗利湿气、振奋脾阳。如果因停食积水，脾气不能运化，进而产生痰饮的，治疗方法宜用消导二陈汤，加入炮姜、姜竹茹、炒枳壳，即可引导排出痰饮，并消除食积、健脾益气。其消导二陈汤方剂列于后：
消导二陈汤方
茅苍术（一钱） 焦白术（一钱） 广陈皮（钱半） 半夏曲（二钱） 茯苓块（二钱） 炒神曲（二钱）
西砂仁（一钱） 炙甘草（五分） 以上各药共用两茶碗水，煎煮成四分之三茶碗浓汁，一次性服用。此药为五岁左右小儿的服用剂量，若为一岁左右小儿须减半。如果在四肢、身体、面部等处生出癣疾及湿疮，这是脾湿外发，湿气散化的征象。切不可在皮肤外部用药涂抹擦拭，以阻断湿气的出路，只可内服清热利湿的药物，脾间气化功能一旦通畅，湿气便会随着气机而消散。其皮肤外部无根的湿毒，不用治疗自然也会结痂痊愈。
Dampness originates from the deficiency of Spleen Qi, which fails to transform and transport fluids for normal circulation. The nature of water is stagnant and immobile; over time, it putrefies and transforms, invading the Spleen Earth, thereby forming various manifestations of Dampness syndromes. Its symptoms include a dark and pale complexion, rough and unmoistened skin, dull purple lips that are not ruddy and vibrant, or phlegm that is easily generated but difficult to resolve, or immediate diarrhea with slight dietary injury, or passage of clear watery stools, or vomiting of sour and putrid food, or body fever accompanied by easy sweating, or limb fatigue with heavy head. All such symptom manifestations belong to Spleen Dampness syndromes. The treatment method uses Cangzhu (Atractylodis Rhizoma) and Baizhu (Atractylodis Macrocephalae Rhizoma) as principal herbs, added with Tu Chao Hang Shao (Earth-fried Paeoniae Radix Alba), Mugua (Chaenomelis Fructus), Hua Binglang (Arecae Semen cum Endocarpo), Banxia Qu (Fermented Pinelliae Tuber), Guang Chenpi (Citri Reticulatae Pericarpium), Chi Fuling (Poria with Red Core), Cheqiancao (Plantaginis Herba), Zhi Gancao (Honey-fried Glycyrrhizae Radix et Rhizoma), and Wumei (Mume Fructus), among others. These are decocted in water into a concentrated liquid and taken while warm, which will surely leach out dampness and invigorate the Spleen Yang. If food stagnation and water retention occur, and Spleen Qi fails to transform them, leading to the generation of Phlegm-Fluids, the treatment method should employ Xiaodao Erchen Tang (Digestion-Assisting Two-Aged Decoction), added with Pao Jiang (Prepared Zingiberis Rhizoma), Jiang Zhuru (Bamboo Shavings with Ginger), and Chao Zhiqiao (Stir-fried Aurantii Fructus Immaturus), which can guide the discharge of Phlegm-Fluids and eliminate food stagnation while strengthening the Spleen. The formula for Xiaodao Erchen Tang is listed below:
Xiaodao Erchen Tang Formula
Maocangzhu (1 qian) Jiaobaizhu (1 qian) Guangchenpi (1.5 qian) Banxiaqu (2 qian) Fulingkuai (2 qian) Chao Shenqu (2 qian)
Xisharen (1 qian) Zhi gancao (0.5 qian) All the above herbs are shared with two tea bowls of water, decocted into three-quarters of a tea bowl of concentrated liquid, and administered at one time. This dosage is for children around five years old; for children around one year old, the dose must be halved. If tinea and eczema appear on the limbs, body, face, etc., this is the outward manifestation of Spleen Dampness dispersing. One must absolutely avoid applying external medications to the skin surface to block the exit path of dampness; instead, only internal administration of Qingre Lishi (Clear Heat and Promote Urination to Drain Dampness) herbs is permissible. Once the Qi transformation within the Spleen is unblocked, dampness will dissipate along with the Qi movement. External damp-toxins without roots on the skin surface will naturally scab and heal without treatment.
