巢氏云∶遗尿者，此由膀胱有冷、不能约于水故也。肾主水，肾气下通于阴，小便者、水之余也，膀胱为津液之府，
既冷气衰弱，不能约水、故遗尿也。汤氏云∶小儿尿床，由膀胱冷，夜属阴，小便不禁，睡里自出，宜破故纸散治之，
益智之剂，亦不可阙。

巢元方说：遗尿，是由于膀胱有寒邪，不能约束尿液所致。肾主水液代谢，肾气向下通达于前阴，小便就是水液的剩余部分；膀胱是储存津液的器官。既然冷气衰弱，不能约束水液，所以发生遗尿。
汤氏说：小儿尿床，是因为膀胱寒冷。夜晚属于阴，小便失去控制，在睡眠中自行流出。适宜用破故纸散治疗，益智固涩的药物也不可缺少。

Chao Yuanfang stated: Enuresis occurs due to cold in the Bladder (Bladder), which fails to restrain water. The Kidney (Kidney) governs water metabolism, and Kidney Qi (Kidney Qi) connects downward to the external genitalia. Urine is the residue of water; the Bladder (Bladder) is the mansion of body fluids. Since the cold qi is weak and unable to restrain water, enuresis results.
Shi Tan said: Bedwetting in children is caused by cold in the Bladder (Bladder). Night belongs to Yin; when urine is incontinent, it flows out spontaneously during sleep. It is appropriate to treat with Pogostemon Powder (Pogostemon San), and astringent and kidney-warming agents should not be omitted.
Pogostemon Powder (Pogostemon San): Treats bedwetting in children at night, caused by cold in the Bladder (Bladder). Night belongs to Yin, leading to urinary incontinence and spontaneous emission during sleep.
Composition: Pogostemonis Fructus (Guzhi, 破故纸) - one ingredient, stir-fried, ground into powder, taken with hot boiled water.
Another prescription:
Alpiniae Oxyphyllae Fructus (Yizhiren, 益智仁) (raw), Poria (Fuling, 白茯苓) (peeled), Poria Cum Radix Polypori (Fushen, 茯神) (peeled), equal parts.
Grind all ingredients into fine powder. Take on an empty stomach mixed with clear tea water. This formula also treats white turbidity.
Yet another prescription:
Chinese Gall (Wubeizi, 五倍子) - half raw, half charred but retaining its nature.
Grind into powder. Form pills using snow sugar. Take thirty pills per dose with rice drink.
Shi Tan said: White urine in children is caused by irregular breastfeeding or weaning, which excessively damages the Spleen (Spleen). Consequently, clear and turbid fluids fail to separate, resulting in urine as white as rice washings. If prolonged, it may develop into infantile malnutrition (Gan syndrome). It may also result from latent heat in the Heart (Heart) and Spleen (Spleen). Treatment should involve regulating Spleen Qi, resolving food stagnation, and promoting urination through the Small Intestine (Small Intestine) and Large Intestine (Large Intestine). Poria Powder (Fuling San) is the primary formula. Sanleng Powder (Sanleng San) and Digestion-Resolving Pills (Xiaoshi Wan) can be selected for use, and Liqing Decoction (Liqing Yin) is also suitable.
Poria Powder (Fuling San): Treats white urine resembling rice washings in children, caused by irregular feeding damaging the Spleen (Spleen), leading to failure to separate clear from turbid fluids.

Sanleng Powder (Sanleng San): Treats white urine in children, caused by irregular feeding excessively damaging the Spleen (Spleen), preventing the separation of clear and turbid fluids.
