补肾水，润三焦
咸温。滋肾水，润三焦，养丹田，安五脏，退骨蒸，软坚块。治虚劳咳嗽，白浊遗精，
为滋阴降火之圣药。若煎炼失道，多服误服，反生燥喝之患（咸能走血，且经 炼，中寓暖
气，使虚阳妄作，则真水愈亏。）《蒙筌》曰∶每月取童便，每缸用石膏七钱，桑条搅澄，
倾去清液，如此二三次，乃入秋露水搅澄（故名秋石）如此数次，滓秽净，咸味减，以重纸
铺灰上晒干，刮去在下重浊，取轻清者为秋石。世医不取秋时，杂收人溺，以皂荚水澄晒为
阴炼，火 为阳炼，尽失于道，安能应病？况经火炼，性却变温耶（秋石再研入罐，铁盏盖
定，盐泥固济升打，升起盏上者名秋冰。味淡而香，乃秋石之精英也。《保寿堂方》∶用童男
童女小便，各炼成秋石，其色如雪，和匀加乳汁，日晒夜露，取日精月华，干即加乳。待四
十九日足，收贮配药。《摘玄》曰∶肿胀忌盐，只以秋石拌饮食佳）。
泻热
甘寒入胃。清痰火，消食积，大解五脏实热。治天行热狂，痘疮血热，黑陷不起。纳甘
草末于竹筒中，紧塞其孔，冬月浸粪缸中。至春取出洗，悬风处阴干，取甘草用（亦有用皂
荚末者，竹须削去青皮）。一云即粪缸多年黄 ， 存性用。
一名金汁
泻火热
主治同人中黄。用棕皮棉纸，上铺黄土，淋粪滤汁，入新瓮，碗复埋土中一年，清若泉
水，全无秽气用。年久者弥佳（野间残粪下土，筛敷痈疽，如冰着背）。
【秋石】
能够补益肾水，滋润三焦。
其味咸，性温。具有滋补肾阴、滋润三焦、养护丹田、安定五脏、退除骨蒸潮热、软化坚硬肿块的功效。用于治疗虚劳咳嗽、小便浑浊、遗精滑泄，是滋阴降火的圣药。如果煎炼方法不当，或者多服、误服，反而会产生燥渴的祸患（因为咸味药物能走血分，且经过炼制后，其中蕴含暖气，会使虚阳妄动，从而导致真阴更加亏损）。《蒙筌》记载：每月收集童便，每缸使用石膏七钱，用桑条搅拌澄清，倒去上层清液，如此重复两三次，然后加入秋季露水搅拌澄清（因此得名“秋石”）。像这样反复多次，直到杂质污秽洗净，咸味减轻，将重纸铺在灰上晒干，刮去底部沉重浑浊的部分，取轻清的部分作为秋石。后世医生不选取秋季采集，而是混杂收集人尿，用皂荚水澄清晾晒称为“阴炼”，用火炼称为“阳炼”，都完全失去了正确的道法，怎么能符合病情呢？况且经过火炼，药性却变成了温性。（将秋石再次研磨装入罐中，用铁盏盖紧，用盐泥密封加固，进行蒸馏升华，升起附着在盏上的物质名为“秋冰”。味道淡而香，这是秋石的精华部分。《保寿堂方》记载：使用童男童女的小便，分别炼制成秋石，颜色如雪，混合均匀后加入乳汁，白天日晒夜晚露置，吸收日精月华，干燥时就再加乳汁。等到四十九天期满，收藏起来配制药物。《摘玄》说：肿胀病忌食盐，只用秋石拌和饮食效果佳）。
【人中黄】
具有泻热功效。
味甘，性寒，入胃经。能清除痰火，消除食积，大幅解除五脏的实热。用于治疗时行热病导致的狂躁、痘疮血热、痘色黑陷不起。将甘草末纳入竹筒中，紧紧塞住孔口，在冬季浸泡在粪缸中。到春季取出清洗，悬挂在通风处阴干，取出甘草使用（也有使用皂荚末的，竹子需削去青皮）。另一种说法是即粪缸中多年的黄色沉淀物，保留药性使用。
【粪清】
又名金汁。
具有泻火热功效。
主治与人中黄相同。使用棕皮棉纸，上面铺设黄土，淋下粪液过滤出汁水，倒入新瓮中，用碗覆盖埋入土中一年，清澈如同泉水，完全没有秽气时使用。存放时间越久越好（野外残留的粪便下沉至土中，筛出敷于痈疽之上，感觉像冰贴在背上一样凉）。
[Qiushi (Refined Human Urine)]
Nourishes Kidney Water, moistens the Sanjiao (Triple Burner).
Salty and warm. It nourishes Kidney Yin, moistens the Sanjiao, nourishes the Dantian (Elixir Field), stabilizes the Zang organs, alleviates bone-steaming tidal fever, and softens hard masses. It treats consumptive coughing, turbid urine, and seminal emission; it is a sacred medicine for nourishing Yin and descending fire. If the decoction and refining process is improper, or if taken in excess or incorrectly, it may instead cause dryness and thirst (since salty substances enter the blood level, and after refining, they contain warm qi, which causes deficient Yang to flare up recklessly, thereby further depleting True Yin). *Mengquan* states: Collect child's urine monthly; for each vat, use seven qian of gypsum, stir with mulberry branches to clarify, and pour off the clear liquid, repeating this two or three times. Then add dew from autumn to stir and clarify (hence the name "Autumn Stone"). Repeat this several times until impurities are clean and salinity is reduced. Spread heavy paper on ash, dry in the sun, scrape off the heavy and turbid parts at the bottom, and take the light and clear part as Qiushi. Modern physicians do not collect during autumn but mix and collect human urine at any time, clarifying and drying with soap pod water, termed "Yin Refining," or using fire, termed "Yang Refining." This completely loses the correct method; how can it treat diseases? Moreover, after fire refining, the nature becomes warm. (Grind Qiushi again, put into a jar, cover tightly with an iron lid, seal firmly with salt mud, and perform sublimation/distillation. The substance rising to the top of the lid is named "Qiu Bing" (Autumn Ice). It has a faint taste and fragrance; it is the essence of Qiushi. *Baoshoutang Fang*: Use urine from healthy boys and girls, refine separately into Qiushi, color like snow. Mix evenly, add milk, expose to sun by day and moonlight by night to absorb the essence of sun and moon. When dry, add more milk. Wait until forty-nine days are complete, store, and prepare medicines. *Zhaixuan* says: For swelling, avoid salt; mixing diet with Qiushi is excellent).
[Renzhonghuang (Human Middle Yellow)]
Drains Heat.
Sweet and cold, enters the Stomach meridian. Clears phlegm-fire, resolves food stagnation, and greatly drains excess heat from the five Zang organs. Treats epidemic febrile diseases causing mania, blood-heat in smallpox/variolous eruptions, and dark, depressed lesions that fail to rise. Put powder of Licorice Root (*Gancao*) into a bamboo tube, plug the hole tightly, and immerse it in a dung pit during winter. Retrieve it in spring, wash, hang in a ventilated place to dry in shade, and use the Licorice Root (sometimes Soap Pod powder is used; the bamboo must have its green skin shaved off). Another view holds that it refers to the yellow sediment accumulated over many years in a dung pit, used retaining its original nature.
[Fenqing (Feces Clear Liquid)]
Also known as Jinzhi (Golden Juice).
Drains Fire-Heat.
Main indications are the same as Renzhonghuang. Use brown cotton paper, spread yellow earth on top, drip fecal matter to filter out the juice, pour into a new urn, cover with a bowl, and bury in the earth for one year. It should be clear as spring water and completely free of foul odor. The older it is, the better (Residual feces from wild areas settle into the soil; sifted and applied to carbuncles and sores, it feels like ice against the back).
