童男（未行房事的年轻男性）的人尿尤其好。
李时珍认为人尿进入胃后输送到脾，再归于肺，向下通调水道进入膀胱，这些都是它原本的通路，因此应当是利水的妙品。然而方书都不主张用它来利水，实在是因为它的味道咸、性质寒凉，主要入血分，不兼走气分，能够滋阴、清热、消瘀，但不能利水。正因为不能利水，所以在滋阴、清热、消瘀方面的功效反而更加显著。寇宗奭说这种药性寒，不宜多服。朱丹溪则极力反驳这一观点，甚至引用一位八十岁的老妇人常服人尿而身体康健作为证据。却不知道人的禀赋各不相同，遇到阳气有余而阴液不足的人，原本能得到益处。如果是阳虚以及血虚而没有热象的人，怎么能适宜服用呢？张仲景的白通加猪胆汁汤中有人尿，是用来平抑呕吐和心烦，泻除阴经中的虚阳。葛洪的葱豉汤中有人尿，是用来防止温邪损伤阴液，或者是阴分的寒邪已经化热，都是取其咸寒清热的功效。只因为是经过脏腑输布转化过的物质，与人身阴气相合，不是其他咸寒性质的药物可以比拟的。所以治疗产妇血晕，以及劳嗽导致血液渗入肺部、吐血、鼻衄等症，（若误用或不当使用），后来反而导致死亡。大概这位妇人本是阳虚体质，等到身体比以前更肥胖时，阳虚也比以前更严重，家人拘泥于之前的疗效而继续使用，恰好招致祸患。寇氏关于性寒的说法，怎么可以忽视呢？
The urine of an unmarried young male is particularly effective.
Li Shizhen stated that human urine, upon entering the stomach, is transported to the spleen, returns to the lungs, and flows downward through the water passages into the bladder; these are its original pathways, so it should be considered a miraculous product for promoting diuresis. However, medical formularies do not primarily advocate its use for diuresis, mainly because its salty and cold nature enters the blood level rather than moving through the qi level. It can nourish yin, clear heat, and resolve stasis, but cannot promote diuresis. Precisely because it cannot promote diuresis, its efficacy in nourishing yin, clearing heat, and resolving stasis becomes more prominent. Kou Zongshi claimed that this substance has a cold nature and should not be taken in large amounts or frequently. Zhu Danxi vigorously refuted this view, even citing an eighty-year-old woman who regularly consumed human urine and remained healthy as evidence. He failed to realize that individuals vary in their innate constitution. For those with excess yang and insufficient yin, it indeed provides benefit. However, for those with yang deficiency and blood deficiency without heat, how could it be suitable? In Zhang Zhongjing's Baitong Decoction with Pig Bile (Baitong Jia Zhudanchi Tang), human urine is included to calm vomiting and irritability, and to drain the false yang within the yin channels. In Ge Hong's Congchi Decoction (Congchi Tang), human urine is included to prevent warm pathogens from damaging yin, or when cold in the yin level has transformed into heat; in both cases, its salty and cold properties are utilized to clear heat. Only because it is a substance that has undergone transformation by the zang-fu organs, harmonizing with the body's yin qi, can it not be compared to other salty and cold substances. Therefore, it is used to treat postpartum blood fainting, as well as laborious coughs where blood infiltrates the lungs, hematemesis, and epistaxis. [However, if misused], it may later lead to death. This was likely because the woman originally had a yang-deficient constitution; when her body became fatter than before, her yang deficiency also worsened. Her family, adhering to previous successful effects, continued to use it, which unfortunately brought disaster. How can Kou's assertion of its cold nature be ignored?
