Yin Syndrome: This condition is characterized by cold limbs, cyanosis of the fingernails, lips, and tongue, and coma with unconsciousness. The treatment involves steaming a ring made of wheat flour and placing it on the umbilicus (Shenque, CV8). Then, five or six hard-boiled eggs, peeled, are placed upright within the ring. A fine silver hairpin is inserted into an egg; after some time, it is withdrawn, and both the hairpin and the egg are replaced. This process continues until the silver hairpin no longer turns black upon withdrawal. (From *Chuan Jiabao*)
Yin Syndrome Abdominal Pain: Take Mingfan (Alumen), Huoxiao (Saltpeter), Hujiao (Black Pepper) (each 1 qian), and Zhen Huangdan (Litharge) (0.8 qian). Grind them into a fine powder and form pills using aged vinegar. Hold the pill in the left palm for men and the right palm for women, securing it with cloth bandages. Recovery occurs when sweating ensues. (From *Qifang Leibian*)
Another prescription: Use Shexiang (Musk) (0.2 fen), insert it into the umbilicus, cover with cloth, and apply heat using a tin pot filled with hot water. Immediate effect is observed. (Ibid.)
Yin Syndrome Hiccup: Burn Ruxiang (Frankincense) together with Liuhuang (Sulfur) and inhale the smoke. (From *Shanghan Yunyao*)
Yin Syndrome Retraction of the Penis: It is necessary to have someone hold the penis firmly in place. Quickly apply moxa cones the size of mung beans, one application at the glans penis and one at the maokou (urethral meatus). The penis will then extend. (From *Jiuji Fang*)
Yin Syndrome Rectal Prolapse: Take Fulonggan (Dragon's House Earth), Bie Tou Gu (Softshell Turtle Head Bone), and Baiyaojian (Fermented Medicinal Pill). Grind them into a fine powder. For each use, take 1-2 qian, decoct strongly, wash the prolapsed area with warm Perilla Decoction, and then apply the medicine mixed with refined sesame oil to the anus. The prolapse will retract immediately. (From *Jingyue Quanshu*)
Critical Yin Syndrome: Boil more than ten eggs until rolling boil. Remove a small portion of the shell from the pointed end of the egg. Cover the umbilicus with the egg. Replace with a hot egg when the previous one cools down. The illness resolves when the eggs are exhausted. These eggs will turn black and must not be eaten. During treatment, the eggs must never touch the hands of the patient with Yin syndrome. (From *Tongshou*)
Another prescription: Take a large handful of Congbai (Scallion White), roughly the size of a tea cup. Roll it tightly in paper, cut it evenly with a sharp knife into slices as thick as a finger. Place a slice on the umbilicus and apply heat with a hot iron. Continue until sweating occurs. If one slice is ineffective, cut another and apply heat again. (Ibid.)
Another prescription: Take Mustard Seed Powder (Jiecaizi Mo), mix with fresh water to form a paste like a plaster, and apply it to the umbilicus. Effect is achieved when sweating occurs. (Ibid.)
