Proctoptosis refers to the prolapse of the anus. It is mostly caused by chronic dysentery leading to deficiency-cold of the Large Intestine (Da Chang). The anus serves as an external indicator of the Large Intestine. When the Large Intestine is deficient and injured by cold, straining during dysentery causes qi to rush downward, resulting in prolapse; hence it is called proctoptosis.
Formula for treating prolapse due to deficiency-cold of the Large Intestine: Zhu Gan San (Pig Liver Powder).
Ingredients: Pig Liver (one slice, thinly sliced and dried), Coptidis Rhizoma (Huanglian, 2 liang, remove roots), Ejiao (Donkey-hide Gelatin, 1 liang, crushed and fried until yellow and dry), Chuanxiong Rhizoma (Chuanxiong, 1 liang), Prunus mume (Wumei) flesh (2.5 liang, slightly fried), Artemisia argyi Folium (Aiye, 1 liang, slightly fried).
Preparation and Administration: Grind the above ingredients into a fine powder through a sieve. Take 2 qian before meals, mixed with rice broth.
Formula for treating intermittent prolapse after defecation due to deficiency-cold of the Large Intestine:
Ingredients: Trionycis Carapax et Plastrum (Bie Tou, one piece, coated with vinegar and roasted until slightly yellow/burnt), Ferri Oxidum Rubrum (Tie Jing, 1 liang, finely ground), Datura Semen (Langdang Zi, 1 liang, washed with water to remove floating seeds, soaked in water to sprout).
Preparation and Administration: Grind the above ingredients into a fine powder through a sieve. Take 2 qian before meals, mixed with rice broth. Additionally, apply heat to the anus using an old hemp shoe sole.

Another prescription:
Apply Iron Powder (Tie Fen) to the anus and press it back in. Apply each time it prolapses until cured.
