金汁：
味甘、苦，性大寒，无毒，归心经。主治时行疫病引起的壮热狂躁，阴虚内燥之热，能解除各种毒素，治疗各种疮疡，埋藏于土中时间越久效果越好。
按语：《素问》说：“浊阴走下窍”，因此它足以制约阳气的亢盛，而心是火的主脏，所以金汁独入心经。制作方法是在冬季取竹箩放在缸上，铺满棕皮，再加几层草纸，将人尿浇在上面，滤出的汁液流入缸中。用新瓮储存，用磁钵盖住，用盐泥封固，埋在地里多年，自然变成像清泉一样的液体，闻起来没有秽气。另一种方法，在腊月取淡竹刮去青皮，浸泡在厕所中取汁也很好。
秋石（白者）：
味甘、咸，性平，无毒，归脾经。主治小儿疳积导致的腹胀满闷，必须在水中漂洗干净，储存在桶中，剖开蛤蟆喂肥后，在烈日下暴晒蒸干，严密覆盖使其死亡，再用文火烘干使用。
按语：蛆本是浊阴下降、流动不拘束的东西，有下行通利的道理，所以专入脾经。用来治疗小儿疳积最为有效。
人中白：
味咸，性寒，无毒，归心、肺二经。主治虚劳发热、吐血衄血，痰喘咳嗽，跌打损伤瘀血，产后败血，生津止渴，能通利大小便，童男的人中白效果更好。积聚在容器上的垢腻，就称为“人中白”，在瓦片上用文火煅烧至存性，用酒和醋炮制，功效与尿液相同，治疗口疮痰结，需露天放置经年者佳。
按语：人尿降火速度最快，朱丹溪说：“气有余便是火”。肺主气，心属火，所以适宜均入这两经，降火而不伤及寒凉，而且补益的功效很大，但本草书中没有提及，可惜啊！褚澄说：“用童便治疗血证，百次治疗不会死一次”，大概才能发挥其作用了。
秋石（黑者/炼者）：
味咸，性微寒，无毒，归肺、肾二经。主治滋养肾水，返本还元，养丹田，归根复命，安和五脏，润泽三焦，消除咳逆稠痰，退除骨蒸劳热，能消除鼓胀，也能软化坚硬积聚，明目清心，延年益寿。
按语：秋石的咸味，本来专入肾经，而肺是肾之母，所以并入肺经。必须使用阴阳双炼的方法，兼而服用，得到坎离既济的含义，苏东坡有炼制方法可供参考。
Jin Zhi (Human Urine Distillate):
Taste is sweet and bitter, nature is greatly cold, non-toxic, enters the Heart Meridian. It primarily treats manic fever caused by epidemic pathogens, dry-heat due to Yin deficiency, resolves all toxins, and cures all sores. Those buried in soil for a long time are superior.
Note: The *Suwen* states: "Turbid Yin exits through the lower orifices," thus it is sufficient to subdue Yang hyperactivity. Since the Heart is the master of Fire, Jin Zhi uniquely enters the Heart Meridian. Preparation method: In winter, place a bamboo basket on top of a vat, cover it fully with palm fiber, add several layers of straw paper, pour urine onto it, and let the filtrate drip into the vat. Store in a new urn, cover with a ceramic bowl, seal tightly with salt mud, bury deep in the ground for many years until it naturally becomes clear like spring water, with no foul odor. Another method: In the twelfth lunar month, take light bamboo, scrape off the green skin, soak it in a latrine to extract juice, which is also good.
Qiu Shi (White):
Taste is sweet and salty, nature is neutral, non-toxic, enters the Spleen Meridian. It primarily treats abdominal distension and fullness caused by pediatric malnutrition (Gan accumulation). It must be rinsed clean in water, stored in a bucket,剖 open frogs fed to fatten them, exposed to the scorching sun until steamed dry, covered tightly to cause death, then dried over gentle fire.
Note: Maggots are substances of turbid Yin that descend and flow without restriction; they possess the principle of descending and purging, hence they specifically enter the Spleen Meridian. They are most effective for treating pediatric Gan syndrome.
Ren Zhong Bai (Calculus Humanis / Urinary Calculus from Vessel):
Taste is salty, nature is cold, non-toxic, enters the Heart and Lung Meridians. It primarily treats heat from consumptive disorders, vomiting blood and epistaxis, phlegm-wheezing and cough, traumatic stasis, postpartum retained blood, generates fluids and quenches thirst, promotes urination and defecation. That from young males is superior. Accumulated scale in vessels is called Ren Zhong Bai. Calcined over gentle fire on tiles until the essence remains, processed with wine and vinegar. Its function is similar to urine. It treats mouth ulcers and phlegm nodules; those exposed to the open air for years are best.
Note: Human urine reduces fire fastest. Zhu Danxi said: "Excess Qi becomes Fire." The Lung governs Qi, and the Heart belongs to Fire, so it appropriately enters both meridians. It reduces fire without injuring with coldness, and its tonifying efficacy is great, yet Materia Medica texts do not mention this, what a pity! Chu Cheng said: "Using child's urine to treat blood disorders, one rarely fails," thereby utilizing its true function.
Qiu Shi (Refined/Dark):
Taste is salty, nature is slightly cold, non-toxic, enters the Lung and Kidney Meridians. It primarily nourishes Kidney Water, returns to the root and restores origin, nourishes the Dantian, returns to the root and restores life, harmonizes the Five Zang Organs, moistens the San Jiao, eliminates thick phlegm with reverse coughing, retreats bone-steaming consumption fever, removes drum-like distension, softens hard accumulations, brightens the eyes and clears the mind, prolongs life and benefits longevity.
Note: The salinity of Qiu Shi originally specializes in entering the Kidney Meridian, and since the Lung is the mother of the Kidney, it enters both. It must be prepared using both Yin and Yang refining methods and taken together, embodying the meaning of Kan and Li achieving balance. Su Dongpo has refining methods available for use.
