纲
详
滑石
（即白虎人参汤。见 病。） 治渴欲饮水。口干燥者主之。
男元犀按。小便不利者水病也。天水一气。金为水母。金气不行则水道不通。曰渴欲饮
水口
气降
（歌见长沙方歌括。） 治脉浮发热。渴欲饮水。小便不利者宜之。
猪苓 茯苓 阿胶 滑石 泽泻
男元犀按。此与五苓散症迥别。五苓散主脾不转输而水停。故发汗利水。为两解表里法。
此
小便排出不畅利的患者，用蒲灰散主治。滑石白鱼散、茯苓戎盐汤也都可以主治。
蒲灰（半分。） 滑石（三分。）
以上三味药，捣碎研成散剂。用温水送服一方寸匕的药量，每天服用三次。
歌诀说：小便不利使用蒲灰散。药性平淡却道理完备。半份蒲灰配三份滑石，能清除湿热不必怀疑猜度。
滑石 乱发（烧制成炭。） 白鱼（各二分。）
以上三味药，捣碎研成散剂。用温水送服一方寸匕的药量，每天服用三次。
歌诀说：滑石加上血余灰（乱发用火焚烧而成，称为血余灰）和白鱼，专门调理血分问题无需犹豫。药物分量相等研磨调和后饮用，用水送服。
茯苓（半斤。） 白术（二两。） 戎盐（如弹丸大小的一枚。）
以上三味药，先将茯苓、白术煎煮成药汁，再加入戎盐继续煎煮。分三次温服。
歌诀说：取一枚如弹丸大小的戎盐。茯苓用半斤则火势自潜。再加上二两白术作为辅助，水源流畅不滞涩自然滋润沾濡。
尤在泾评论说：蒲香即香蒲。宁原评论说：香蒲能去除湿热，通利小便。与滑石配合是清利小便的正统方法。《别录》记载：白鱼开胃下气，去除水气。血余灰治疗转胞导致的小便不通。与滑石配合起到滋阴益气，从而通利小便的作用。
纲目详细记载：滑石。
（即白虎加人参汤，见某病篇。） 主治口渴想喝水，口舌干燥的患者。
男元犀按语：小便不利属于水液代谢疾病。天水一气相通，肺金为肾水之母。肺气不行则水道不通。所谓口渴想喝水，口...气降...
（歌诀见《长沙方歌括》。） 主治脉象浮、发热，口渴想喝水，小便不利的患者适宜使用此方。
猪苓 茯苓 阿胶 滑石 泽泻
男元犀按语：此证与五苓散的症状截然不同。五苓散主治脾脏不能转运输布而水液停聚，所以采用发汗和利水的方法，是表里双解的法度。此...
Patients with difficult urination are primarily treated with Puhui San (Cattail Pollen Powder). Huashi Baiyu San (Talcum and White Fish Powder) and Fuling Rongyan Tang (Poria and Military Salt Decoction) are also indicated.
Puhui (Cattail Pollen, 0.5 fen.) Huashi (Talcum, 3 fen.)
The above three ingredients are pounded into a powder. Take one fangcun bi (approx. 2-3 grams) with warm water, three times daily.
The verse states: For difficult urination, use Puhui. Its efficacy is profound despite its simplicity. Half part Puhui combined with three parts Talcum effectively clears damp-heat without doubt.
Huashi (Talcum) Luanfa (Burnt Human Hair, prepared by burning) Baiyu (White Fish, each 2 fen.)
The above three ingredients are pounded into a powder. Take one fangcun bi with warm water, three times daily.
The verse states: Huashi combined with Xueyuhui (Blood Residue Ash, made by burning human hair) and Baiyu specifically regulates the blood level; hesitate not. The ingredients are equal in dosage, ground together and taken with water.
Fuling (Poria, 8 liang.) Baizhu (Atractylodes Macrocephala Rhizome, 2 liang.) Rongyan (Military Salt, one piece the size of a bullet.)
The above three ingredients: first decoct Fuling and Baizhu. Then add Rongyan and continue decocting. Divide into three doses and take warm.
The verse states: Take one piece of Military Salt the size of a bullet. Use eight liang of Poria to subdue fire naturally. Assist with two liang of Atractylodes Macrocephala Rhizome; when the source flows freely without stagnation, moisture naturally nourishes.
You Zaijing commented: Puxiang refers to Typha angustifolia. Ning Yuan commented: Typha angustifolia removes damp-heat and promotes urination. Combined with Talcum, it forms the orthodox method for clearing and promoting urination. *Bencao Bie Lu* records: Baiyu (Silverfish) opens the stomach, directs Qi downward, and removes fluid retention. Xueyuhui treats urinary retention due to bladder displacement (Zhuanbao). Combined with Talcum, it nourishes Yin and benefits Qi to facilitate urination.
*Bencao Gangmu* details: Huashi (Talcum).
(That is, Baihu Jia Renshen Tang [White Tiger plus Ginseng Decoction], see Disease Chapter.) It is indicated for patients who desire to drink water due to thirst and have dry mouth and tongue.
Nan Yuanxi noted: Difficult urination is a disorder of water metabolism. Heaven and Water are one Qi; Metal (Lung) is the mother of Water (Kidney). If Lung Qi does not circulate, the water passages become obstructed. Regarding thirst and desire to drink water... Qi descends...
(The verse is seen in *Changsha Fang Ge Kuo*.) It is suitable for patients with floating pulse, fever, thirst with desire to drink, and difficult urination.
Zhu Ling (Polyporus) Fuling (Poria) Ejiao (Donkey-hide Gelatin) Huashi (Talcum) Zexie (Alisma Rhizome)
Nan Yuanxi noted: This condition is distinctly different from Wuling San syndrome. Wuling San primarily treats water retention due to Spleen's failure in transportation and distribution; thus, it employs sweating and diuresis as a method to resolve both exterior and interior simultaneously. This...
