若要治疗小儿痘疮脱落后的修复，将人齿垢烧制成粉末，用热酒调服吞下。它能托毒外出以治愈豌豆疮（天花），也可用于驱除虫毒和邪气。将人齿垢与黑虱共同研磨成粉，涂抹于箭头造成的伤口或痈肿破溃处，可促进愈合。取清晨初醒时的唾液，涂抹于柔软的疖肿上，也能消除痈肿，效果显著。此外，唾液还能明目、退翳消肿、解毒辟邪。
人爪甲味甘、咸，无毒。孕妇的爪甲，取其细末点入眼中，可去除翳障；普通人的爪甲，可催生下胎衣。它有利小便的作用，兼治尿血，以及调理阴阳易病。且能止住鼻出血，细细刮取爪甲末敷之，立即可愈。
人粪味苦，气寒。对于疔肿导致口张不开的情况，用新鲜粪便敷贴一天，可使病灶根部腐烂脱落；对于伤寒热毒，可用干粪（火烧存性后研末）用水澄清后的汁液饮用，以清除患处的热毒。古法流传的粪清（人粪水），常宜备用。其制作方法如下，但疗效难以迅速达到。选择厕所中不混杂污浊物的粪便为佳，时间须在寒冬腊月才最妙。将竹箩搁在盆上，棕皮铺在箩中。加入数层浓纸，放入五寸厚的新土。将粪便浇在土上，渗出的汁液滴落在下方的盆中。用新瓮储存盛放，用粗碗覆盖。用盐泥密封加固，埋入地下深处。取出时如清泉般清澈，打开闻则无秽气。治疗天行时疫引起的发热尤为适宜，治疗阴虚燥热也特别好。凡百种疮疡皆可驱除，一切毒素均可化解。（另一种方法：截取淡竹削去青皮，浸泡在粪便中，取渗透出的汁液服用。）还有地清（地浆），需在一个时辰内制作，选择阴凉洁净的黄土地。挖五六寸深的小坑，放入二三匙粪末（干粪研细）。汲取新水搅浑，（制作过程如同造地浆一样）。等待片刻澄清后饮用；不要刻意喝太多，也能解除大热狂渴。人中黄性冷，朱丹溪的方剂中常加入。截取竹子削去青皮，两头保留节段。在上端开孔，填入甘草片填满；再塞住孔洞，用桐油灰密封固定。立冬时节投入厕所，立春前取出。竖立在通风处，经过十几天半月后破开。取出甘草晒干，用于治疗疫毒任选用。（另一种方法：冬季取一段竹子，刮去青皮。保留底部一节，其余节段打通，将大甘草放入其中，用木塞塞住上窍。将保留节段的一端插入粪便中，一个月后取出晒干，使用浸泡时间长的效果更好。）若能获得新生婴儿的粪便，患疮蚀息肉即可去除。（也能去除面部的印记文字。）捞起粪蛆，放入容器中，再用稻草做成把柄引蛆升上来，移到另一只容器中，则不洁的粗细杂质都去除了。剖开癞蛤蟆投入其中，两天后使其肥满。）烈日曝晒蒸烤，盖密即死。用文火烘干，研细备用。与白术一起做成散剂，用汤药调服，治疗小儿疳积胀满有神奇疗效。蛔虫也会随粪便排出，其性大寒；大的洗净切断，取汁液滴入。多年的赤眼，滴入后即痊愈。经云：盐能消解蛔虫，功效同蚯蚓。
To treat the recovery after the shedding of smallpox in children, burn the human dental calculus (Ren Chi Gou) into powder, and swallow it mixed with hot wine. It can promote the expulsion of toxins to cure smallpox (Wandou Chuang), and is also capable of expelling worm toxins and evil qi. Grind human dental calculus together with black lice into a paste; applying this to arrowhead wounds or ruptured carbuncles can facilitate healing. Collect saliva at dawn; applying it to soft boils can reduce swelling and inflammation, with verified efficacy. Furthermore, saliva can brighten the eyes, remove nebulae, reduce swelling, detoxify, and ward off evil.
Human fingernails have a sweet and salty taste, and are non-toxic. The nails of pregnant women, when taken as fine powder and applied to the eyes, can remove nebulae; the nails of ordinary people can induce the delivery of the placenta. They promote urination, treat hematuria, and regulate Yin-Yang exchange disease. They also stop epistaxis; scraping them finely and applying them brings immediate cessation.
Human feces have a bitter taste and cold nature. For carbuncles causing the mouth to remain open, applying fresh feces for one day causes the root of the lesion to rot and fall off; for heat toxins from typhoid fever, drinking the clarified water from dry feces (burned until carbonized and ground) clears the heat toxin from the affected area. Ancient traditions recommend keeping fecal liquor (Fen Qing) on hand. The preparation method is as follows, though effects may not be immediate. Select feces from a latrine that are free from impurities; the best time is during the deep winter months. Place a bamboo basket over a basin, line the basket with palm fiber cloth. Add several layers of thick paper, then five inches of new soil. Pour feces onto the soil so that the juice drips through into the basin. Store in a new urn, cover with a coarse bowl, seal tightly with salt mud, and bury deep underground. When retrieved, it resembles clear spring water, odorless upon opening. It is particularly effective for treating epidemic fevers caused by heavenly pathogens, and excellent for treating yin deficiency with dry heat. It can dispel all kinds of sores and resolve all toxins. (Another method: Cut a section of light bamboo, remove the green skin, soak it in feces, and drink the seeping juice.) There is also "Di Qing" (Earth Liquid), prepared within one shichen (two hours). Choose clean yellow earth in a shady place. Dig a small pit five or six inches deep, add two or three spoons of fecal powder (dry feces ground fine). Draw fresh water, stir until turbid (similar to making Di Jiang). Wait for it to clarify briefly before drinking; do not consume excessively, as it also resolves severe heat and thirst. Ren Zhong Huang has a cold nature and is often added to formulas by Zhu Danxi. Cut bamboo, removing the green skin, leaving nodes at both ends. Open a hole at the top, fill it completely with slices of licorice root; reseal the hole and fix it with tung oil putty. Throw it into a latrine on the Start of Winter, retrieve it before the Start of Spring. Stand it in a ventilated place, break it open after ten days to half a month. Take out the licorice root, dry it in the sun, and use it to treat epidemic toxins. (Another method: In winter, take a section of bamboo, scrape off the green skin. Leave one node at the bottom, clear the other nodes, insert a large piece of licorice root inside, and plug the top with wood. Insert the end with the node into feces, retrieve after one month, dry in the sun; longer soaking yields better results.) If fresh infant feces can be obtained, they can remove ulcerative polyps. (They can also remove facial marks/texts.) Scoop up fly larvae, place them in a container, use a straw bundle to guide the larvae upward, transfer them to another container, thereby removing all impurities. Inject dissected toad into them, and they become fat in two days.) Expose to strong sunlight to bake, cover tightly to kill. Dry with gentle fire, grind fine for storage. Mix with Atractylodis Rhizoma (Baizhu) to make a powder, administer with decoction; it is miraculous for treating pediatric malnutrition and abdominal distension. Ascarids may also exit via feces due to its cold nature; wash large ones, cut them, and drip the juice. For chronic red eyes, instilling the juice brings immediate cure. The classics state: Salt can dissolve ascarids, with efficacy similar to earthworms.
