(The feces of a sow are superior.)

(The juice dried in the shade can also be used to mix with medicines.)

(Pigs are aquatic animals, but their stomach belongs to Earth in the Five Elements theory. Therefore, formulas use the pig's stomach to treat stomach diseases, embodying the principle of "treating the stomach with the stomach.")

(The method for preparing gelatin is the same as that for Deer Antler Gelatin (Lujiaojiao). To obtain horn frost, soak the horn in water for seven days, scrape off the skin and horny debris, place it in a silver vessel, and soak in cow's milk for one day. Add more milk when consumed until no further consumption occurs. Seal the bottle mouth with oiled paper. Place three inches of barley at the bottom of a pot, set the bottle on top, and fill the surroundings with barley. Soak in water for one fu period (approx. two hours), replenishing water as needed until the debris softens like flour. Remove, dry by roasting, and grind into powder/frost for use.)

(Roast until brittle, grind into powder, and take with wine.)

(Roast until crisp and grind. The number of lobes in the livers of various livestock is fixed; only the Otter Liver (Tatan) grows one lobe per month, totaling twelve lobes in twelve months. There are also regressed lobes among them. When using, one must observe the morphology to verify authenticity; otherwise, most are counterfeit.)

(Ointment oil added to plasters can miraculously draw out dampness. It was used in the plasters of the Zhao residence.)

(This item is often counterfeit. There is a sea beast called "Water Black Dragon" (Shuiwulong). Sea people catch and kill it to extract its kidneys for medicinal compounding, which may lead to errors as the substance differs. One identification method: genuine items have two layers of thin skin wrapping a pill-like meat core, with three yellow hairy strands on the skin. If kept in a dark, humid place, it remains fresh year-round. Additionally, if placed on the head of a sleeping dog, the dog will startle and go mad upon touching it; this indicates authenticity. Soak in wine overnight, wrap in cloth, roast over low heat until green, finely chop, and pound alone. Storing with Sichuan Pepper (Hanjiao) and Camphor (Zhangnao) prevents spoilage.)

(When using Sparrow Feces (Quefen), do not use the feces of sparrows with yellow mouths that have not yet mated; this type is called Que Su (Quesu) and is not used medicinally. The feces of male sparrows are pointed and round at both ends. Upon collection, first discard those found near Aconite (Fuzi) growing in rainy areas. Grind in a mortar into powder, soak overnight in Licorice Decoction (Gancao Tang), pour off the supernatant, drain the Licorice water completely, dry by roasting, and use as needed. Ri Huazi stated: Birds that cover their right wing with the left are male, and their feces are pointed and straight at the head.)

(When using, select specimens weighing one jin. First wipe off hairs from the meat, remove claws and intestines, retaining the meat, wings, beak, and feet. Soak in good wine overnight, remove, and coat with five liang of natural juice of Polygonatum Rhizome (Huangjing). Roast until the coating is exhausted and the specimen is dry. Another method retains only the inherent nature of the drug (Cunxing). Modern users mostly retain only the inherent nature. Xian Yunshi considers Shi (Real/Seed) as its guiding herb.)

(It is the feces of the bat (Fuyi), known dialectally as Tian Shu, also named Ye Ming Sha (Night-Shining Sand). When collecting, wash with water to remove ash, soil, and foul odors, take the fine sand, dry in the sun, and roast for use. This sand is actually the eyes of mosquitoes and midges. Avoid using with White Peony Root (Bailian) and Cynanchum Atratum (Baiwei).)
