（俗谓之肚，中脘穴分，即中焦也）
统属足太阴脾经（《灵枢》曰∶足太阴之脉，循膝股内前廉入腹。是动则病腹胀善噫，得后与气，则快然如
衰。又曰∶太阴终者，腹胀闭，不得息，善噫善呕；呕则逆，逆则面赤，不逆则上下不通；上下不通则面黑，
皮毛焦而终矣。又曰∶足太阴之别，名曰公孙，去本节之后一寸，别走阳明，其别者入络肠胃。厥气上逆则
霍乱；实则肠中切痛，虚则鼓胀，取之所别也。又曰∶腹胀满，食不化，腹响响然不能大使，取足太阴。《
素问》曰∶阴中之至阴，脾也。腹者，至阴之所居。又曰∶脾病内舍心腹，外在肌肉四肢。又曰∶黄脉之至
也，大而虚，有厥气在腹中。厥气，名曰疝厥，女子同法。得之疾使四肢汗出当风。又曰∶中气不足，谓之
脾虚，则腹满肠鸣，飧泄，食不化。又曰∶伤寒十日，太阴病衰，腹减如故，则思饮食。又曰∶太阴之厥，
则腹满 胀，后不利，不欲食，食则呕，不得卧。又曰∶脾疟者，令人寒则腹中痛，热则肠中鸣，已汗出。
李东垣曰∶中脘痛者，太阴也，理中汤或建中汤，及草豆蔻丸之类主之）。又属足阳明胃经（《灵枢》曰∶
足阳明之脉，其支者起于胃口，下循腹里。所生病者，大腹水肿。《素问》曰∶腹中鸣者，病本于胃也。薄
脾，则烦不能食，食不下者，胃脘膈也。又曰∶胃疟者，令人善饥而不能食，食而支满腹大。杨上善曰∶足
阳明脉，从鼻起，下咽，分为四道，并正别脉六道，上下行腹，纲维于身）。兼属手太阳小肠经、少阳三焦
经之会。（《素问》曰∶腹暴满，按之不下，取手太阳经络者，胃之募也。注∶胃募，中脘穴也，居蔽骨与
脐之中，手太阳小肠、足阳明脉所生也）。又属足少阴肾经、厥阴肝经（《灵枢》
曰∶腹满，大便不利，腹大，亦上走胸嗌，喘息渴渴然，取足少阴。又曰∶足之三阴，从足走腹。《素问》曰∶
肾病者，腹大胫肿，虚则胸中痛，大腹、小腹痛。又曰∶肝热病者，小便先黄，腹痛多卧，身热）。又属冲脉、
任脉之会（《灵枢》曰∶冲脉、任脉之浮而外者，循腹右上行，会于咽喉。又曰∶任脉之别，散于腹。实则腹
皮痛，虚则瘙痒，取之所别也。《素问》曰∶冲脉挟脐上行，至胸中而散。故冲脉为病，则逆气里急也。沈承
之曰∶腹分四行，中行脐上五寸，名上脘穴，属足阳明胃经、手太阳小肠经、任脉之会。脐上四寸，名中脘穴，
又谓之上纪，属手太阳小肠经、少阳三焦经、足阳明胃经、任脉之会。脐上二寸，名下脘穴，属足太阴脾经、
任脉之会。第二行去中行左右各开五分，属足少阴肾经、冲脉之会。第三行去中行左右各开二寸，属足阳明胃
经。第四行去中行左右各开三寸五分，属足太阴脾经、阴维脉之会）。
主要归属于足太阴脾经（《灵枢》记载：足太阴脾经的经脉，沿大腿内侧前缘进入腹部。该经发生病变会出现腹胀、容易嗳气等症状，若大小便通畅或排气后，症状就会缓解减轻。又说：足太阴脾经气机终绝时，会出现腹部胀满闭塞，呼吸不畅，频繁嗳气和呕吐；呕吐则气机上逆，气逆则面色发红，若不逆则上下气机不通；上下不通则面色发黑，皮肤毛发枯焦而死亡。又说：足太阴脾经的别络，名叫公孙，位于本节后一寸处，别行走向阳明经，其分支联络肠胃。若厥气上逆则导致霍乱；实证表现为肠中剧烈疼痛，虚证表现为鼓胀，治疗应取该别络。又说：腹部胀满，食物不消化，腹部发出响声且不能大便，应取足太阴脾经穴位。《素问》记载：阴中之至阴，指的是脾。腹部，是至阴之气所居之处。又说：脾病在内则影响心腹，在外则影响肌肉四肢。又说：脾脉（黄脉）搏动大而空虚，是因为有厥气在腹中。这种厥气，称为疝厥，女子发病规律相同。这是由于急于活动四肢，汗出当风所致。又说：中气不足，称为脾虚，会导致腹部胀满、肠鸣、完谷不化的泄泻、食物不消化。又说：伤寒病第十日，太阴病衰退，腹部胀满消退恢复常态，开始想吃东西。又说：太阴经气厥逆，会导致腹部胀满，二便不利，不想吃东西，吃了就呕吐，无法安卧。又说：患脾疟的人，发冷时腹中疼痛，发热时肠中鸣响，并且已经出汗。李东垣说：中脘部位疼痛，属于太阴病，可用理中汤或建中汤，以及草豆蔻丸等方剂主治）。
同时归属于足阳明胃经（《灵枢》记载：足阳明胃经的支脉，起于胃口，向下沿腹腔内运行。该经所生的疾病，有大腹水肿。《素问》记载：腹中鸣响，病根在于胃。邪气迫近脾脏，则心烦不能进食，食物难以下咽，这是胃脘膈阻的症状。又说：患胃疟的人，容易感到饥饿但不能进食，进食后则胸胁支满、腹部胀大。杨上善说：足阳明经脉，从鼻部起始，下行至咽喉，分为四道，连同正脉和别脉共六道，上下行走于腹部，维系全身）。
兼属手太阳小肠经、少阳三焦经的交会之处。（《素问》记载：腹部突然胀满，按压不凹陷，应取手太阳小肠经络穴，即胃的募穴。注：胃募是中脘穴，位于剑突与脐之间，是手太阳小肠经、足阳明胃经所生之处）。
又归属于足少阴肾经、厥阴肝经（《灵枢》记载：腹部胀满，大便不利，腹部膨大，气甚至向上走到胸部和咽喉，喘息口渴，应取足少阴肾经穴位。又说：足部的三条阴经，从足部走向腹部。《素问》记载：肾病的人，腹部肿大、小腿肿胀，虚证则胸痛、大腹和小腹疼痛。又说：患肝热病的人，小便先变黄，腹痛嗜卧，身体发热）。
又归属于冲脉、任脉的交会之处（《灵枢》记载：冲脉、任脉浮行于体表的分支，沿腹部右侧上行，会合于咽喉。又说：任脉的别络，散布于腹部。实证则腹皮疼痛，虚证则瘙痒，治疗应取该别络。《素问》记载：冲脉挟脐上行，至胸部而散开。所以冲脉发病，会出现气机上逆、腹中拘急疼痛的症状。沈承之说：腹部经脉分为四行，中间一行在脐上五寸，名为上脘穴，属足阳明胃经、手太阳小肠经、任脉的交会处。脐上四寸，名为中脘穴，又称上纪，属手太阳小肠经、少阳三焦经、足阳明胃经、任脉的交会处。脐上二寸，名为下脘穴，属足太阴脾经、任脉的交会处。第二行距离中间一行左右各五分，属足少阴肾经、冲脉的交会处。第三行距离中间一行左右各二寸，属足阳明胃经。第四行距离中间一行左右各三寸五分，属足太阴脾经、阴维脉的交会处）。
(Commonly known as the belly, divided by the Zhongwan (CV12) acupoint, which belongs to the Middle Jiao (Middle Burner))
Primarily governed by the Foot-Taiyin Spleen Meridian (The *Ling Shu* states: The meridian of the Foot-Taiyin follows the anterior aspect of the inner knee and thigh into the abdomen. When this meridian is affected, it causes abdominal distension and frequent belching; relief is felt after defecation or passage of flatus. It also states: At the termination of the Taiyin, there is abdominal fullness and closure, inability to breathe, frequent belching and vomiting; if vomiting occurs, qi rebels upward, causing redness of the face; if it does not rebel, there is obstruction between the upper and lower parts; such obstruction leads to a black complexion, with dry skin and hair, marking the end of life. Furthermore: The collateral branch of the Foot-Taiyin is named Gongsun (SP4), located one cun posterior to the root of the first metatarsal bone, diverging to connect with the Yangming meridian, with its branches entering and connecting to the intestines and stomach. Rebellious Qi upwards results in Huoluan (cholera-like syndrome); excess conditions manifest as severe cutting pain in the intestines, while deficiency conditions manifest as drum-like distension; treatment should target this collateral branch. Additionally: For abdominal fullness, food stagnation, audible borborygmi, and constipation, points on the Foot-Taiyin should be selected. The *Su Wen* states: The Yin within Yin is the Spleen. The abdomen is the residence of the Ultimate Yin. It further states: Spleen disease internally affects the heart and abdomen, and externally affects muscles and limbs. Also: When the Huang Mai (Yellow Pulse, associated with Earth/Spleen) is large and empty, it indicates Jue Qi (rebellious/cold Qi) residing in the abdomen. This Jue Qi is called Shan Jue (Hernia Jue), following the same pattern in women. It arises from exerting the limbs vigorously while sweating and exposed to wind. Moreover: Insufficiency of Middle Qi is termed Spleen Deficiency, leading to abdominal fullness, borborygmi, undigested stool diarrhea, and food stagnation. It is also stated: In the tenth day of Shanghan (Cold Damage), when the Taiyin disease declines, abdominal distension subsides to normal, and appetite returns. Regarding Taiyin Jue (Jue Syndrome of Taiyin): abdominal fullness and distension, difficulty in bowel movements, anorexia, postprandial vomiting, and insomnia occur. Regarding Pi Nue (Spleen Malaria): chills cause abdominal pain, heat causes intestinal rumbling, accompanied by sweating. Li Dongyuan states: Pain at Zhongwan is a Taiyin condition, treated with Lizhong Tang (Regulate the Middle Decoction), Jianzhong Tang (Build the Middle Decoction), or Caodoukou Wan (Cardamom Pill)).
It also belongs to the Foot-Yangming Stomach Meridian (The *Ling Shu* states: A branch of the Foot-Yangming meridian originates from the stomach opening and descends along the interior of the abdomen. Diseases generated by this meridian include massive abdominal edema. The *Su Wen* states: Borborygmi in the abdomen originates from the Stomach. If pathogenic factors encroach upon the Spleen, irritability and anorexia occur; difficulty swallowing food indicates obstruction at the epigastrium. It also states: Patients with Wei Nue (Stomach Malaria) feel hungry but cannot eat; upon eating, they experience chest/flank fullness and abdominal enlargement. Yang Shangshan states: The Foot-Yangming meridian begins at the nose, descends through the throat, dividing into four channels, combined with the main and collateral meridians totaling six paths, traveling up and down the abdomen to regulate the body).
It serves as a confluence for the Hand-Taiyin Small Intestine Meridian and the Shaoyang Sanjiao Meridian (The *Su Wen* states: For sudden abdominal fullness that does not depress upon pressure, select the Luo-connecting point of the Hand-Taiyang Small Intestine Meridian, which is the Mu-Alarm point of the Stomach. Note: The Mu-Alarm point of the Stomach is Zhongwan (CV12), located midway between the xiphoid process and the umbilicus, where the Hand-Taiyang Small Intestine and Foot-Yangming Stomach meridians originate).
It also belongs to the Foot-Shaoyin Kidney Meridian and the Jueyin Liver Meridian (The *Ling Shu* states: For abdominal fullness, difficulty in defecation, abdominal enlargement, and Qi rushing upward to the chest and throat causing panting and thirst, select points on the Foot-Shaoyin Kidney Meridian. It also states: The three Yin meridities of the foot travel from the foot to the abdomen. The *Su Wen* states: Kidney disease manifests as abdominal swelling and leg edema; deficiency presents as chest pain, and pain in the great and small abdomen. It also states: Heat disease of the Liver presents with yellow urine first, abdominal pain, lethargy, and fever).
It is a confluence of the Chong Mai (Penetrating Vessel) and Ren Mai (Conception Vessel) (The *Ling Shu* states: The superficial and external branches of the Chong and Ren meridians ascend along the right side of the abdomen and converge at the throat. It also states: The collateral branch of the Ren Mai scatters over the abdomen. Excess conditions cause pain in the abdominal skin, while deficiency causes itching; treatment targets this collateral branch. The *Su Wen* states: The Chong Mai ascends alongside the umbilicus, dispersing in the chest. Therefore, Chong Mai pathology manifests as rebellious Qi and internal tension/pain. Shen Chengzhi states: Abdominal meridians are divided into four rows. The central row, five cun above the umbilicus, is named Shangwan (CV13), a confluence of the Foot-Yangming Stomach, Hand-Taiyang Small Intestine, and Ren meridians. Four cun above the umbilicus is named Zhongwan (CV12), also called Shangji, a confluence of the Hand-Taiyang Small Intestine, Shaoyang Sanjiao, Foot-Yangming Stomach, and Ren meridians. Two cun above the umbilicus is named Xiawan (CV10), a confluence of the Foot-Taiyin Spleen and Ren meridians. The second row, 0.5 cun lateral to the center on both sides, is a confluence of the Foot-Shaoyin Kidney and Chong meridians. The third row, two cun lateral to the center on both sides, belongs to the Foot-Yangming Stomach Meridian. The fourth row, 3.5 cun lateral to the center on both sides, is a confluence of the Foot-Taiyin Spleen and Yinwei Mai (Yin Linking Vessel)).
