Tuogang (Rectal Prolapse) refers to the condition where the anus protrudes outward. It is mostly caused by chronic dysentery leading to deficiency and coldness of the Large Intestine. Furthermore, the anus serves as the external manifestation (Hou) of the Large Intestine. When the Large Intestine is deficient and injured by cold pathogens, and during dysentery, excessive straining causes Qi to rush downward, resulting in the prolapse of the anus; hence it is called Tuogang.
