实生于土，故水泻而土又不可不培也，培其土而木气始能养耳。方用两宜汤∶
茯苓（五钱） 白术（一两） 薏仁（五钱） 柴胡（五分） 龙胆草（一钱） 茵陈（一钱）
郁李仁（五分） 水煎服。二剂轻，四剂又轻，十剂全愈。
此方利湿无非利胆之气，利胆无非健脾之气也。脾土健，土能克水，则狂澜可
障，自然水归膀胱尽从小便而出矣。
此症用竹茹龙胆汤亦效。
白芍（一两） 龙胆草 半夏（各一钱） 茯苓（五钱） 茵陈 竹茹（各二钱） 白术（三钱） 水煎服。
人有小便点滴不能出，小腹臌胀，两足浮肿，一身发黄，人以为黄瘅矣，谁知
是膀胱湿热，结而成瘅乎。夫膀胱之经，气化则能出水，无热气，则膀胱闭而不行，
无清气，则膀胱亦闭而不行。所以，膀胱寒则水冻而不能化，膀胱热则水沸而亦不
能化。黄瘅之病，无不成于湿热。是膀胱之黄瘅，乃热病而非寒病也。热而闭结必
解热，寒而闭结必祛寒。第黄瘅既成于湿热，宜解热而不宜祛寒矣。然而祛寒者，
必用热药以温命门之火；解热者，必用凉药以益肺金之气。盖肺气寒，则清肃之令
下行于膀胱，而膀胱不能闭结也。方用清肺通水汤∶
白术（一两） 萝卜子（一钱） 茯苓（三钱） 半夏（一钱） 麦冬（三钱） 桑白皮（三钱）
茵陈（一钱） 泽泻（二钱） 车前子（三钱） 黄芩（二钱） 苏子（二钱） 水煎服。一剂小便
微利，二剂小便大利，四剂而黄瘅之症全消。
此方虽与扬肺利湿汤大同小异，实有不同也。扬肺利湿汤，提肺之气也；清肺
通水汤，清肺之气也。二方皆有解湿之药，而利与通微有异，利则小开其水道，而
通则大启其河路也。
此症用通流饮亦效。
茯苓（五钱） 白术（三钱） 桂枝（五分） 茵陈（一钱） 木通 车前子（各二钱） 水煎服。
湿邪源于脾土，因此在水泻（水样腹泻）的情况下，脾土不可不加以培补，只有培补了脾土，肝木之气才能得以滋养。方剂用两宜汤：茯苓（五钱）、白术（一两）、薏苡仁（五钱）、柴胡（五分）、龙胆草（一钱）、茵陈（一钱）、郁李仁（五分），用水煎服。服用两剂后症状减轻，四剂后更轻，十剂后完全痊愈。
此方利湿，无非是疏利胆气；疏利胆气，无非是健脾益气。脾土健运，土能克水，则狂澜可挡，自然水液归入膀胱，全部从小便排出。
此症使用竹茹龙胆汤也有效。
白芍（一两）、龙胆草、半夏（各一钱）、茯苓（五钱）、茵陈、竹茹（各二钱）、白术（三钱），用水煎服。
有人小便点滴不出，小腹胀满，双足浮肿，全身发黄，人们以为是黄瘅（黄疸病），谁知这是膀胱湿热，凝结而成瘅证。膀胱经的气化功能正常才能排出尿液，如果没有热气，膀胱就会闭塞而不行；如果没有清气，膀胱也会闭塞而不行。所以，膀胱寒则水液冻结而不能气化，膀胱热则水液沸腾也不能气化。黄瘅之病，没有不是由湿热形成的。膀胱的黄瘅，属于热病而非寒病。热而闭结必须解热，寒而闭结必须祛寒。既然黄瘅是由湿热形成，应当解热而不宜祛寒。然而，祛寒者，必用热药以温补命门之火；解热者，必用凉药以益肺金之气。因为肺气寒，则清肃的政令下行于膀胱，膀胱就不会闭结。方剂用清肺通水汤：
白术（一两）、萝卜子（一钱）、茯苓（三钱）、半夏（一钱）、麦冬（三钱）、桑白皮（三钱）、茵陈（一钱）、泽泻（二钱）、车前子（三钱）、黄芩（二钱）、苏子（二钱），用水煎服。服用一剂后小便微微通畅，二剂后小便大量通畅，四剂后黄瘅的症状全部消除。
此方虽然与扬肺利湿汤大同小异，但实际上有所不同。扬肺利湿汤，是提升肺气的；清肺通水汤，是清泄肺气的。两方都有祛湿的药物，但“利”与“通”略有不同，“利”是稍微开通水道，而“通”是大大开启河路。
Dampness originates from the Spleen Earth; therefore, in cases of watery diarrhea (Shuixie), the Spleen Earth must not fail to be fortified. Only by fortifying the Earth can the Qi of Wood be nourished. The formula used is Liangyi Tang:
Poria (5 qian), Atractylodis Macrocephalae Rhizoma (1 liang), Coicis Semen (5 qian), Bupleuri Radix (5 fen), Gentianae Scabrae Radix (1 qian), Artemisiae Scopariae Herba (1 qian), Prunus humilis seed (5 fen). Decoct with water and take orally. After two doses, symptoms lighten; after four doses, they lighten further; after ten doses, complete recovery occurs.
The purpose of this formula in draining dampness is none other than to promote the Qi of the Gallbladder; promoting the Qi of the Gallbladder is none other than to strengthen the Spleen and benefit Qi. When Spleen Earth is robust, Earth controls Water, thereby holding back the raging waves, allowing natural water flow into the Bladder to exit entirely through urination.
For this condition, Zhuru Longdan Tang is also effective.
White Peony Root (1 liang), Gentianae Scabrae Radix, Pinelliae Tuber (each 1 qian), Poria (5 qian), Artemisiae Scopariae Herba, Bamboo Shavings (each 2 qian), Atractylodis Macrocephalae Rhizoma (3 qian). Decoct with water and take orally.
There are cases where a person cannot pass even a few drops of urine, with abdominal distension, edema in both feet, and yellowing of the whole body. People assume this is Huangdan (Jaundice), but who would know it is actually Damp-Heat in the Bladder condensing into Dan syndrome? The meridians of the Bladder rely on Qi transformation to excrete water. Without warm Qi, the Bladder closes and fails to function; without clear Qi, the Bladder also closes and fails to function. Thus, Cold in the Bladder causes water to freeze and fail to transform, while Heat in the Bladder causes water to boil and also fail to transform. Huangdan disease invariably arises from Damp-Heat. Therefore, Huangdan of the Bladder is a Heat disease, not a Cold disease. If closure is due to Heat, one must resolve Heat; if closure is due to Cold, one must dispel Cold. Since Huangdan is formed by Damp-Heat, one should resolve Heat rather than dispel Cold. However, to dispel Cold, one must use Hot medicines to warm the Fire of the Mingmen (Gate of Life); to resolve Heat, one must use Cool medicines to benefit the Qi of Lung Metal. For if Lung Qi is Cold, its clearing and descending command descends to the Bladder, preventing closure. The formula used is Qingfei Tongshui Tang:
Atractylodis Macrocephalae Rhizoma (1 liang), Raphani Semen (1 qian), Poria (3 qian), Pinelliae Tuber (1 qian), Ophiopogonis Tuber (3 qian), Morus Alba Root Bark (3 qian), Artemisiae Scopariae Herba (1 qian), Alismatis Rhizoma (2 qian), Plantaginis Seed (3 qian), Scutellariae Radix (2 qian), Perillae Fruit (2 qian). Decoct with water and take orally. After one dose, urination becomes slightly free; after two doses, urination becomes very free; after four doses, all symptoms of Huangdan disappear.
Although this formula is largely similar to Yangfei Lishi Tang, there are actual differences. Yangfei Lishi Tang lifts the Qi of the Lung; Qingfei Tongshui Tang clears the Qi of the Lung. Both formulas contain drugs that resolve dampness, but "Li" (draining) and "Tong" (unblocking) differ slightly. "Li" slightly opens the water pathways, whereas "Tong" greatly opens the river channels.
For this condition, Tongliu Yin is also effective.
Poria (5 qian), Atractylodis Macrocephalae Rhizoma (3 qian), Cinnamomi Ramulus (5 fen), Artemisiae Scopariae Herba (1 qian), Tetrapanacis Medulla, Plantaginis Seed (each 2 qian). Decoct with water and take orally.
