肛门，大肠候也。大肠虚冷，其气下冲者，肛门反出。亦有因产，用力努偃，气冲其肛
，亦令反出也。
阴肿者，是虚损、受风邪所为。胞络虚而有风邪客之，风气乘于阴，与血气相搏，令气
血痞涩，腠理壅闭，不得泄越，故令阴肿也。
阴痛之病，由胞络伤损，致脏虚受风邪。而三虫、九虫因虚动作，食阴则痛者，其状成
疮。其风邪乘气冲击而痛者，无疮，但疼痛而已。
阴疮者，由三虫、九虫动作，侵食所为也。诸虫在人肠胃之间，若腑脏调和，血气充实
，不能为害。若劳伤经络，肠胃虚损，则动作侵食于阴，轻者或痒或痛，重者生疮也。
诊其少阴之脉，滑而数者，阴中生疮也。
胞络伤损，子脏虚冷，气下冲，则令阴挺出，谓之下脱。亦有因产而用力偃气，而阴下
脱者。
诊其少阴脉浮动，浮则为虚，动则为悸，故令下脱也。
此由胞络虚损，冷热不调，风邪客之，邪气乘于阴，搏于血气，变而生 肉也。其状如
鼠乳。
此或因带下，或举重，或因产时用力，损于胞门，损于子脏，肠下乘而成 。
痔病，由劳伤经络，而血流渗之所成也。而有五种∶肛边生疮，如鼠乳出在外，时出脓
血者，牡痔也；肛边肿，生疮而出血者，牝痔也；肛边生疮，痒而复痛出血者，脉痔也；肛
边肿核痛，发寒热而出血者，肠痔也。因便而清血出者，血痔也。
Anal prolapse is caused by deficiency-cold of the Large Intestine. When the Large Intestine is deficient and cold, with Qi rushing downward, the anus turns outward. There are also cases due to childbirth, where excessive straining causes Qi to rush upward and impact the anus, also leading to prolapse.
Yin swelling is caused by deficiency and invasion of Wind pathogen. When the Bao Luo (uterine collaterals) are deficient and invaded by Wind, the Wind pathogen attacks the Yin region, battling with Blood and Qi, causing stagnation and涩ness of Qi and Blood, blocking the Cou Li (skin pores and interstices), preventing dispersion, thus causing swelling of the Yin.
Diseases of Yin pain arise from damage to the Bao Luo, leading to Zang deficiency and susceptibility to Wind pathogen. The Three Worms and Nine Worms (parasites) become active due to deficiency; if they consume the Yin, pain occurs, manifesting as sores. If pain is caused by Wind pathogen impacting Qi, there are no sores, only pain.
Yin sores are caused by the activity of the Three Worms and Nine Worms, which invade and consume tissue. Various worms reside in the intestines and stomach; if the Fu and Zang are harmonious and Qi and Blood are abundant, they cannot cause harm. However, if labor and fatigue damage the collaterals and the intestines and stomach become deficient, the worms become active and consume the Yin. Mild cases present with itching or pain, while severe cases develop sores. Palpating the Shao Yin pulse, if it is slippery and rapid, it indicates sores in the Yin.
Damage to the Bao Luo and deficiency-cold of the Zi Zang (uterus), with Qi rushing downward, causes the Yin to protrude, known as "Xia Tuo" (prolapse). There are also cases due to childbirth, where excessive straining disrupts Qi, leading to prolapse of the Yin. Palpating the Shao Yin pulse, if it is floating and moving, floating indicates deficiency, and moving indicates palpitations/restlessness, thus causing prolapse.
Labor and damage to the Bao Luo, and deficiency of the Zi Zang, allow Cold-Damp to invade. Cold attacks the Yin, thus causing a sensation of cold.
This is due to deficiency and damage of the Bao Luo, imbalance of Cold and Heat, and invasion of Wind pathogen. The pathogenic factor attacks the Yin, battles with Qi and Blood, and transforms into flesh growths. The appearance resembles mouse nipples.
This may be due to leukorrhea, lifting heavy objects, or excessive effort during childbirth, damaging the Bao Men (vaginal opening) and the Zi Zang (uterus), allowing the intestine to descend and form hemorrhoids.
Hemorrhoids are formed by labor and fatigue damaging the collaterals, causing blood to leak and seep. There are five types: Sores appearing at the anal margin, protruding outward like mouse nipples, occasionally discharging pus and blood, are called Mu Zhi (Yang Hemorrhoids); Swelling at the anal margin with sores and bleeding are called Pin Zhi (Yin Hemorrhoids); Sores at the anal margin with itching followed by pain and bleeding are called Mai Zhi (Vascular Hemorrhoids); Swollen nodules at the anal margin with pain, accompanied by chills and fever and bleeding are called Chang Zhi (Intestinal Hemorrhoids); Clear blood discharged during defecation is called Xue Zhi (Blood Hemorrhoid).
