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).
