（一名小腹，即下焦也）属足厥阴肝经、任脉之会（《灵枢》曰∶足厥阴之脉，过阴器，
抵小腹。又曰∶肝胀者，胁下满，而痛引小腹。又曰∶小腹满大，上走胃至心，淅淅身时寒热，小便不利，取
足厥阴。《素问》曰∶厥阴之厥，则少腹肿痛，腹胀，泾溲不利。又曰∶足厥阴之疟，令人腰痛，少腹满，小
便不利如癃状。李东垣曰∶少腹痛，厥阴也，重则正阳散、回阳汤主之；轻则当归四逆汤主之。王海藏曰∶玄
胡索，治心气痛、少腹痛如神，入足厥阴也）。又属手足太阳小肠、膀胱经（《灵枢》曰∶小肠胀者，小腹
胀，引腰而痛。膀胱胀者，小腹满而气癃。又曰∶小肠病者，少腹满痛，腰脊控睾而痛，时窘之后，耳前热。
若寒甚，若肩上热，及手小指次指间热。膀胱病者，小腹偏肿而痛，以手按之，即欲小便而不得，肩上热。
又曰∶小腹痛肿，不得小便，邪在三焦约。取之太阳大络，视其络脉，与厥阴小络结而血者。顾英白曰∶三焦
约者，即膀胱也，故经又曰∶三焦病者，腹胀满，小腹尤坚，不得小便，时窘急，溢则水溜，此皆小肠、膀胱
病也。盖小肠者，膀胱之源；膀胱者，小肠之委。而心与小肠，实相为表里，故心包与三焦，亦相为表里。而
膀胱、三焦，经文时并称之耳，岂别有所谓三焦之腑哉）。又属足少阴肾、太阴脾经（《素问》∶黑脉之至也，
上坚而大，有积气在小腹与阴，名曰肾痹，得之沐浴清水而卧。注∶清，冷也。又曰∶邪客于足太阴之络，令
人腰痛，引少腹控眇，不可以仰息。《灵枢》曰∶身有所伤，血出多，及中风寒，若有所堕坠，四肢懈堕不收，
名曰体惰，取其小腹、脐、三交结。三交结者，阳明、太阴也）。
（少腹又称小腹，即下焦所在部位）归属于足厥阴肝经与任脉的交会处（《灵枢》记载：足厥阴肝经的经脉，经过生殖器，抵达小腹。又说：肝胀的病证，表现为胁下胀满，疼痛牵引至小腹。又说：小腹胀满肿大，向上延伸至胃部和心窝，身体时常感到寒冷发热，小便不利，治疗应取足厥阴经穴。《素问》记载：厥阴经气逆乱所致的厥证，会出现少腹肿痛、腹胀、大小便不通利。又说：足厥阴经的疟疾，使人腰痛，少腹胀满，小便不利如同癃闭的症状。李东垣说：少腹痛属于厥阴经病，重症用正阳散或回阳汤主治；轻症用当归四逆汤主治。王海藏说：玄胡索治疗心气痛、少腹痛效果如神，因为它入足厥阴经）。又归属于手太阳小肠经和足太阳膀胱经（《灵枢》记载：小肠胀的病证，表现为小腹胀，疼痛牵引腰部。膀胱胀的病证，表现为小腹胀满且气机阻滞导致排尿困难。又说：小肠病的症状，包括少腹满痛，腰脊牵拉睾丸疼痛，时常窘迫急迫地想排便，耳前发热。如果寒气很重，或者肩部发热，以及手小指和次指之间发热。膀胱病的症状，表现为小腹偏侧肿胀疼痛，用手按压时，就想小便却排不出来，肩部发热。又说：小腹痛肿，不能小便，是邪气在三焦约束所致。治疗应取足太阳经的大络，观察其络脉，若与厥阴经的小络结聚而有瘀血者，则予以处理。顾英白说：三焦约束的病证，实际上就是膀胱的病证，所以经文又说：三焦病的症状，表现为腹胀满，小腹尤其坚硬，不能小便，时常窘迫急迫，水液溢出则流淌，这些都是小肠和膀胱的病证。大概小肠是膀胱的源头，膀胱是小肠的末端。而心与小肠互为表里，所以心包与三焦也互为表里。至于膀胱和三焦，经文中时常并称，难道还有另外所谓的三焦之腑吗？）。又归属于足少阴肾经和足太阴脾经（《素问》记载：黑色的脉象出现时，脉搏上部坚实而大，说明有积滞之气在小腹和阴部，这种病名叫肾痹，是因为在冷水中沐浴后睡觉所致。注释：清，指寒冷。又说：邪气侵犯足太阴脾经的络脉，使人腰痛，疼痛牵引少腹并牵及腰骶部，不能仰卧呼吸。《灵枢》记载：身体受到外伤，出血过多，以及中风寒，或者有堕坠伤，四肢懈怠无力无法收持，这种病名叫体惰，治疗应取小腹、脐部、三交结处的穴位。所谓三交结，是指阳明经和太阴经的交会之处）。
(The Shaofu, also known as the Xiaofu or lower Jiao) is the intersection of the Foot-Jueyin Liver Meridian and the Ren Mai (Conception Vessel). (*Ling Shu* states: The meridian of the Foot-Jueyin passes through the genitalia and reaches the Shaofu. It further states: In cases of Liver distension, there is fullness under the hypochondrium with pain radiating to the Shaofu. Additionally, if the Shaofu is full and enlarged, extending upwards to the stomach and heart, accompanied by chills and fever, and difficult urination, one should select points from the Foot-Jueyin. *Su Wen* states: In Jueyin Jue syndrome, there is swelling and pain in the Shaofu, abdominal distension, and difficulty in passing urine and stool. It also states: Malaria affecting the Foot-Jueyin causes lower back pain, fullness in the Shaofu, and urinary difficulty resembling Gong syndrome. Li Dongyuan stated: Pain in the Shaofu belongs to the Jueyin; severe cases are treated with Zhengyang San or Huiyang Tang, while mild cases are treated with Danggui Sini Tang. Wang Haicang stated: Yanhusuo is effective for treating Heart Qi pain and Shaofu pain, as it enters the Foot-Jueyin.) It also belongs to the Hand-Taiyang Small Intestine Meridian and the Foot-Taiyang Bladder Meridian (*Ling Shu* states: Small Intestine distension presents with Shaofu distension and pain radiating to the waist. Bladder distension presents with Shaofu fullness and Qi stagnation leading to urinary retention. Furthermore, Small Intestine disease manifests as Shaofu fullness and pain, lower back and spine pain radiating to the testicles, frequent urgency to defecate, and heat in front of the ears. If the cold is severe, or if there is heat in the shoulder or between the little finger and the ring finger. Bladder disease manifests as unilateral swelling and pain in the Shaofu; upon palpation, there is an urge to urinate but inability to do so, accompanied by heat in the shoulder. It also states: Shaofu pain and swelling with inability to urinate indicates pathogenic factors constrained in the Triple Burner. Treatment involves selecting the large Luo-connecting vessels of the Taiyang, observing the collaterals for blood stasis where they intersect with the small collaterals of the Jueyin. Gu Yingbai stated: Constrained Triple Burner pathology essentially refers to Bladder pathology; thus, the classics state that Triple Burner disease presents with abdominal fullness, particularly firmness in the Shaofu, inability to urinate, and frequent urgency, with overflow causing water leakage. These are all diseases of the Small Intestine and Bladder. Essentially, the Small Intestine is the source of the Bladder, and the Bladder is the termination of the Small Intestine. Since the Heart and Small Intestine are exterior-interior pairs, the Pericardium and Triple Burner are also exterior-interior pairs. The texts often mention the Bladder and Triple Burner together, implying no separate "Triple Burner organ" exists beyond this relationship.) It also belongs to the Foot-Shaoyin Kidney Meridian and the Foot-Taiyin Spleen Meridian (*Su Wen* states: When the black pulse arrives, being firm and large at the upper position, it indicates accumulated Qi in the Shaofu and Yin region, a condition named Shen Bi (Kidney Bi), caused by bathing in cold water and lying down. Note: Qing refers to cold. It also states: Pathogenic factors invading the Luo-connecting vessel of the Foot-Taiyin cause lower back pain radiating to the Shaofu and the lumbar-sacral region, making supine breathing difficult. *Ling Shu* states: Following physical trauma with excessive bleeding, contraction of wind-cold, or falls resulting in limbs that are flaccid and unable to hold themselves, termed Ti Duo (Body Languor), treatment involves selecting points at the Shaofu, umbilicus, and Sanjiao Jie (Three Crossings Intersection). Sanjiao Jie refers to the intersection of the Yangming and Taiyin meridians).
