*Zhubing Yuanhou Lun* states: Tuogang (prolapse of the rectum) refers to the protrusion of the anus from the body, mostly caused by chronic diarrhea leading to deficiency-cold of the Large Intestine. When the Large Intestine is deficient and injured by cold pathogens, excessive straining during defecation...
*Qianjin Fang* states: For the treatment of Tuogang (prolapse of the rectum), one should avoid lifting heavy objects and wearing tight belts, and abstain from sexual intercourse for a year; this yields the best results.
*Meilue Fang* states: In treating Tuogang (prolapse of the rectum), be cautious about lifting heavy loads, avoid consuming slippery foods, and do not wear tight clothing belts.
*Dujuan Fang* contains an effective prescription for Tuogang (prolapse of the rectum):
Puhuang (Corylinae Pollen, two liang) Zhugao (Porci Cerebrum/Adipose Tissue, three he)
Crush and mix these two substances, apply them to the anus, and manually push it back into place. It will heal within no more than two or three applications.
Another prescription: Take Niwei (Anemarrhenae Rhizoma, one sheng), burn it, and use the smoke to fumigate the anus; this leads to immediate cure.
*Ge Shi Fang* contains a prescription for sudden prolapse of the rectum during defecation:
Moxibustion at the center of the hair whorl on the vertex (Baihui, GV20), 100 moxa cones.
Another prescription: Mix Zhugao (Porci Cerebrum/Adipose Tissue) with Puhuang (Corylinae Pollen), press it into the anus, or simply dust powder externally; both are effective.
Yet another prescription: Heat Duanshi (Hematitum calcined), wrap it in old cotton cloth, and sit on it. Replace when it cools down. Soak it in bean paste, then apply wine to the area.
It also states: If the intestine protrudes along with the anus and expands such that it cannot be reduced, crush fresh Gualua (Trichosanthis Fructus), extract the juice, warm it, add Zhugao (Porci Cerebrum/Adipose Tissue), wash hands, and gently press until it retracts naturally.
Another prescription: Heat Duanshi (Hematitum calcined), wrap it in cloth, and apply hot compresses while pressing the anus back into place.

Crush the earth into a powder, apply it to the protruding part of the anus. Roast Zaojiao (Gleditsiae Fructus) until warm, and alternately apply hot compresses. The goal is reduction of the prolapse.
It also states: Prescription for pressing back using roasted hemp shoe soles:
Juba Malvudi Sole (Old worn Hemp Shoe Sole, one piece) Bie Tou (Testudinis Carapax et Plastrum head, one piece)
Burn both items. Crush the Bie Tou (Testudinis Carapax et Plastrum head) into a powder and apply it to the protruding anus. Hold the shoe sole and press the anus back in; it will stop protruding.
It also states: Prescription for chronic Tuogang (prolapse of the rectum) lasting years without healing:
One dead Bie Tou (Testudinis Carapax et Plastrum head), burn until smoke ceases, grind into fine particles, apply to the anus, push upward, and press with hand. (Note: *Bencao Shiyi* states: There are examples of using similar substances as medicine: such as Woniú (Helix Aspersa/Milk Snail) and Bie Tou (Testudinis Carapax et Plastrum head); burning them into powder and applying them treats Tuogang (prolapse of the rectum), causing natural retraction. This follows the principle of "treating like with like.")
Another prescription: Moxibustion at Guiwei (Weizhong, BL40 / Coccyx area) brings immediate cure; this refers to the tip of the coccyx.
It also states: Prescription for Tuogang (prolapse of the rectum) caused by accumulated cold and diarrhea:
