诸淋皆肾虚所致。心为火，肾为水，水火平永无此疾。水火不平，心火燥肾水，肾虚小肠膀胱皆生热，故
诸淋之症生。淋有五∶有膏淋，如脂膏浮于水上，此肾虚不能制其肥液而不行也。有热淋，下焦有热，热传于
肾，流入于胞，其溺黄涩热极，或出鲜血，茎中痛甚，甚至令人闷乱，遍身有汗而后流出，治法并宜行滞
气，利小便，解邪热，平心火。心清则小便自利，而血不妄，切不可用补药。气得补而愈胀，血得补而愈涩，热
得补而愈盛，愈痛也。亦有肾虚受寒，为冷淋。其症先寒战而后热，宜微温。

膏淋加黄柏，冷淋加沉香、木香，热淋宜本方加淡竹叶，血淋加蒲黄、地榆，石淋加生
淡竹叶，利小便药内少加升麻、柴胡，不然气不行也。

所有的淋证（以小便频数短涩、滴沥刺痛、欲出未尽、小腹拘急或痛引腰腹为特征的病证）都是由肾虚引起的。心属火，肾属水，如果水火平衡，就永远不会有这种疾病。如果水火不平衡，心火燥热而肾水亏虚，导致肾虚的小肠和膀胱都产生热邪，因此各种淋证的病症就会发生。淋证分为五种：有膏淋，尿液像脂膏一样浮在水面上，这是由于肾虚不能制约体内的肥腻液体而导致排泄异常。有热淋，下焦有热邪，热邪传变到肾，流入胞宫（此处指代泌尿系统相关部位），小便颜色黄且排尿涩滞灼热感极强，甚至排出鲜血，尿道中疼痛剧烈，严重时令人烦闷混乱，全身出汗后症状才缓解，治疗方法应当行滞气、利小便、解邪热、平心火。心火清降则小便自然通利，血液也不会妄行，切不可使用补药。气得到补益会更加胀满，血得到补益会更加涩滞，热邪得到补益会更加旺盛，疼痛也会加剧。也有因肾虚受寒导致的冷淋。其症状是先出现寒战而后发热，治疗宜用微温之法。
五淋的主方：
赤茯苓、陈皮、甘草梢、山栀（宣化肺气）、车前子、木通、莲肉、黄连、块滑石、猪苓、泽泻、瞿麦、灯心草、升麻（炒制）、柴胡（炒制）。
膏淋加黄柏；冷淋加沉香、木香；热淋宜在本方基础上加淡竹叶；血淋加蒲黄、地榆；石淋加生淡竹叶；在利小便的药物中少量加入升麻、柴胡，否则气机无法运行。
小儿溺白尿（尿液色白如米泔水），是由于饮食不节制，导致损伤脾胃，胃中的浊气渗入膀胱，因此清浊不分，尿液白如米泔水，适宜燥除中焦脾胃的湿气。用药如下：
厚朴、苍术、半夏、枳实、青皮、山楂、香附、茯苓、陈皮、甘草。
也有因心膈间伏藏热邪者，适宜清心火并利小便。用药如下：
黄连、莲肉、茯苓、甘草梢、陈皮、厚朴、猪苓、车前子、滑石、泽泻、灯心草。
All types of Lin syndrome (a disease characterized by frequent and urgent urination, scanty and painful stream, incomplete emptying, and discomfort in the lower abdomen or pain radiating to the waist) are caused by Kidney deficiency. The Heart belongs to Fire, and the Kidney belongs to Water; if Water and Fire are balanced, this disease will never occur. If Water and Fire are unbalanced, Heart Fire becomes dry and scorching while Kidney Water is deficient, causing Heat to generate in the deficient Kidney, Small Intestine, and Bladder, thus giving rise to various symptoms of Lin syndrome. There are five types of Lin:
1. Gao Lin (Paste-like Lin): The urine resembles fat floating on water. This is due to Kidney deficiency failing to control the body's fatty fluids, leading to abnormal excretion.
2. Re Lin (Heat-type Lin): There is Heat in the Lower Jiao (lower abdominal region). The Heat transmits to the Kidney and flows into the Bao Luo (uterus/bladder area). The urine is yellow, with a very hot and astringent sensation during urination, sometimes accompanied by fresh blood. There is severe pain in the urethra, and in severe cases, it causes mental restlessness and confusion. Symptoms may only subside after profuse sweating throughout the body. The treatment method should involve promoting Qi circulation, promoting diuresis, clearing pathogenic Heat, and pacifying Heart Fire. When Heart Fire is cleared, urination naturally becomes smooth, and blood ceases to flow recklessly. Tonifying medicines must strictly be avoided. Tonifying Qi exacerbates distension; tonifying Blood exacerbates astringency; tonifying Heat exacerbates its intensity and pain.
3. Leng Lin (Cold-type Lin): Caused by Cold invading due to Kidney deficiency. The symptoms include chills preceding fever. Treatment should employ mild warming methods.
Main Formula for the Five Lins:
Chi Fu Ling (Red Poria), Chen Pi (Aged Tangerine Peel), Gan Shao (Licorice Root Tip), Shan Zhi (Gardenia Fruit - transforms Lung Qi), Che Qian Zi (Plantago Seed), Mu Tong (Akebia Stem), Lian Rou (Lotus Seed Meat), Huang Lian (Coptis Rhizome), Kuai Hua Shi (Talcum), Zhu Ling (Polyporus), Ze Xie (Alisma Rhizome), Qu Mai (Dianthus Herb), Deng Xin Cao (Juncus Medulla), Sheng Ma (Bupleurum Root - stir-fried), Chai Hu (Bupleurum Root - stir-fried).
Modifications:
For Gao Lin, add Huang Bo (Phellodendron Bark); for Leng Lin, add Chen Xiang (Aquilaria Wood) and Mu Xiang (Vladimiria Root); for Re Lin, add Dan Zhu Ye (Lophatherum Herb) to the base formula; for Xue Lin (Blood-type Lin), add Pu Huang (Typha Pollen) and Di Yu (Sanguisorba Root); for Shi Lin (Stone-type Lin), add raw Dan Zhu Ye. In diuretic formulas, add small amounts of Sheng Ma and Chai Hu; otherwise, Qi movement will not occur.
Pediatric Bai Niao (White Urine):
This condition, where urine is white like rice washings, results from irregular diet damaging the Spleen and Stomach. Turbid Qi from the Stomach seeps into the Bladder, causing a failure to distinguish between clear and turbid substances. Treatment should focus on drying Dampness in the Middle Jiao (Spleen/Stomach).
Formula:
Hou Po (Magnolia Bark), Cang Zhu (Atractylodes Rhizome), Ban Xia (Pinellia Tuber), Zhi Shi (Immature Bitter Orange), Qing Pi (Green Tangerine Peel), Shan Zha (Hawthorn Fruit), Xiang Fu (Cyperus Rhizome), Fu Ling (Poria), Chen Pi (Aged Tangerine Peel), Gan Cao (Licorice Root).
Alternatively, for cases involving latent Heat in the Heart and Diaphragm, the treatment should clear Heart Fire and promote diuresis.
Formula:
Huang Lian (Coptis Rhizome), Lian Rou (Lotus Seed Meat), Fu Ling (Poria), Gan Cao Shao (Licorice Root Tip), Chen Pi (Aged Tangerine Peel), Hou Po (Magnolia Bark), Zhu Ling (Polyporus), Che Qian Zi (Plantago Seed), Hua Shi (Talcum), Ze Xie (Alisma Rhizome), Deng Xin Cao (Juncus Medulla).
