脊端穷骨（即尾椎骨尽头处）有一个穴位，名叫龟尾。在此处艾灸三壮，可以治疗肠风泻血，症状即可痊愈。施灸时必须让患者身体颠倒才能准确取穴。
对于久患冷症的五痔便血，可在脊中穴艾灸一百壮。（出自《千翼》）
何教授和汤簿都有这种多年积年的疾病，都通过一次艾灸而除根。汤簿因此传授了这个方法。后来查阅灸经发现，这个穴位原本用于治疗小儿脱肛和泻血。这大概是岐伯治疗小儿的方法。后人便沿用此法来治疗大人的肠风泻血罢了。因为大人和小儿的病症起初并没有太大差异。
五痔便血且伴有失屎（大便失禁），可在回气穴艾灸一百壮。该穴位位于脊骨穷骨上方，赤白脉交会的下方。（出自《铜人腧穴针灸图经》）
治疗肠风的药物很多，但大多没有疗效。为什么呢？《本草衍义》说：肠风其实就是肠痔。如果知道它是痔疮并针对痔疮进行治疗，就没有不生效的。
如果要艾灸治疗肠风，长强穴是关键穴位。近来李仓患有肠风，市井医生用拐杖测量脐中位置，在脊骨正对脐中的地方进行艾灸，病立即痊愈。我因此为人艾灸治疗肠风，都能除根。（陆氏方记载可治下血除根。）
复溜穴、（见痢疾章节）束骨穴、会阳穴、（见泄泻章节）主治肠澼。（出自《千翼》）中都穴，治疗肠澼及疝气小腹痛。（出自《铜人腧穴针灸图经》）四满穴，治疗肠澼剧烈疼痛。（见积聚章节）
结积留饮形成的囊状物，导致胸满、饮食不消化，可艾灸通谷穴五十壮。（出自《千翼》）大肠俞穴，主治风邪引起的腹中雷鸣声、大肠病变、肠澼泄痢、食物不消化、小腹绞痛、腰脊疼痛僵硬、大小便困难、无法进食等症状，可艾灸一百壮，分三次施灸。
各种结积留饮形成的囊状物，导致胸满、饮食不消化，可艾灸通谷穴五十壮；另外再艾灸胃管穴三百壮，分三次施灸。第十五椎骨下方的名极俞穴，主治腹中疾病、腰痛、膀胱寒、水饮注下等症，灸量随患者年龄而定。（出自《千翼》）会阳穴，主治腹中有寒导致的泄泻注下、肠澼便血。束骨穴，主治肠澼泄泻。膺窗穴，主治肠鸣泄泻注下。阳纲穴，主治大便失控、小便赤黄、肠鸣泄泻注下。
The bone at the end of the spine, known as the coccyx (the terminal part of the vertebral column), has an acupoint named Guwei (Tortoise Tail). Moxibustion of three moxa cones (Zhuang) at this point cures Changfeng bleeding from the intestines. The patient must be inverted to accurately locate and treat this point.
For chronic cold-induced hemorrhoids (Wuzhi) with rectal bleeding, one hundred moxa cones can be applied at Jizhong. (From *Qianyi*)
Professor He and Clerk Tang both suffered from this condition for years, yet a single application of moxibustion eradicated the root cause. Clerk Tang subsequently transmitted this method. Upon consulting the Moxibustion Classics, it was found that this acupoint was originally used to treat prolapse of the rectum and bloody diarrhea in children. This is likely the method of Qibo for treating pediatric cases. Later generations adopted this method to treat Changfeng bleeding in adults, as the initial pathology in adults and children is essentially the same.
For hemorrhoids with rectal bleeding accompanied by fecal incontinence, apply one hundred moxa cones at Huiqi. This point is located above the coccyx, below the intersection of the red and white vessels. (From *Tongren Shuxue Zhenjiu Tujing*)
Changqiang treats Changfeng with rectal bleeding. (See *Tongren Shuxue Zhenjiu Tujing: Hemorrhoids Section*)
There are many herbs for treating Changfeng, but most are ineffective. Why? *Bencao Yan Yi* states that Changfeng is actually intestinal hemorrhoids. If one recognizes it as hemorrhoids and treats accordingly, there will be no failure.
If using moxibustion for Changfeng, Changqiang is the essential acupoint. Recently, Li Cang suffered from Changfeng. A city physician measured from the umbilicus with a staff and applied moxibustion on the spine opposite the umbilicus, resulting in immediate cure. I have since treated others for Changfeng with moxibustion, achieving permanent remission. (Lu's Formula records treatment for rectal bleeding with permanent cure.)
Fuliu (see Dysentery section), Shugu, and Huiyang (see Diarrhea section) primarily treat Changpi. (From *Qianyi*)
Zhongdu treats Changpi and hernia with lower abdominal pain. (From *Tongren*) Siman treats severe pain from Changpi. (See Accumulation and Collection section)
Accumulated fluid retention forming cysts, causing chest fullness and indigestion, can be treated with fifty moxa cones at Tonggu. (From *Qianyi*) Dachangshu primarily treats wind causing borborygmus in the abdomen, large intestine disorders, Changpi with dysentery, undigested food, severe lower abdominal cramping, stiffness and pain in the waist and spine, difficulty in urination and defecation, and inability to eat. Apply one hundred moxa cones, divided into three sessions.
Various accumulated fluid retention cysts causing chest fullness and indigestion can be treated with fifty moxa cones at Tonggu; additionally, apply three hundred moxa cones at Weiguan, divided into three sessions. Mingjishu, located below the fifteenth thoracic vertebra, primarily treats abdominal diseases, lower back pain, bladder cold, and downward flow of retained fluids. The number of moxa cones should correspond to the patient's age. (From *Qianyi*) Huiyang primarily treats cold-induced watery diarrhea and Changpi with rectal bleeding. Shugu primarily treats Changpi diarrhea. Yingchuang primarily treats borborygmus and watery diarrhea. Yanggang primarily treats uncontrolled defecation, dark yellow urine, and borborygmus with watery diarrhea.
Sanjiaoshu, Xiaochangshu, Xi liao, Yishe, and Zhangmen primarily treat borborygmus, abdominal distension, and impending watery diarrhea. (From *Qianyi*)
