（饱气也，俗作嗳气）
〔仲〕上焦竭，善噫，何谓也？师曰∶上焦受中焦气未和，不能消，是故能噫耳。（经云∶卫
出于上焦。）上焦不归者，噫而酢酸。（经云∶不归不至也。上焦之气不至其部，则物不能传化，
故噫而酢吞。）噫属心脾，及二阳一阴。经云∶心为噫。又云∶太阴所谓上走心为噫者。阴盛
而上走于阳明，阳明络属心为噫，故曰上走心为噫也。又云∶二阳一阴发病，主惊骇背痛，善噫

三曰，风攻脾虚而噫。又云∶厥阴在泉，风淫所胜，腹胀善噫是也。
针灸噫独取脾。经云∶脾足太阴之脉，是动则病腹胀，善噫，视盛虚热寒陷下取之也。
〔仲〕寸口脉弱而缓，弱者阳气不足，缓者胃气有余，噫而吞酸，食卒不下，气填于膈上。
〔《脉》〕寸脉紧，寒之实也。寒在上焦，胸中必满而噫。趺阳脉微而涩，微无胃气，涩即伤脾，
寒在膈而反下之，寒积不消，胃微脾伤，谷气不行，食已自噫，寒在胸膈，上虚下实，谷气不通，
为闭塞之病。趺阳脉微涩，及寸脉紧而噫者，皆属寒。（全文见诊条。）太阴中者，腹胀闭，
噫气呕逆。
( Yi, referring to belching after fullness, is commonly written as "Ai Qi" in vernacular usage.)
[Zhang Zhongjing] When the Upper Jiao (Upper Burner) function declines, frequent belching occurs. What is the reason? The Master said: The Upper Jiao receives Qi from the Middle Jiao (Middle Burner). If the Qi of the Middle Jiao is not harmonized and cannot digest food, belching ensues. (The Classic states: Wei Qi (Defensive Qi) originates from the Upper Jiao.) If the Qi of the Upper Jiao does not return to its proper place, one will belch and experience acid regurgitation. (The Classic states: If it does not return, it does not arrive. When the Qi of the Upper Jiao fails to reach its designated area, food transmission and transformation are hindered, leading to belching and acid swallowing.) Belching is associated with the Heart and Spleen, and involves the Yangming and Jueyin meridians. The Classic states: The Heart governs belching. It also states: In Taiyin disorders, when Qi moves upward to the Heart causing belching, it is because Yin excess moves upward to Yangming; the collaterals of Yangming connect to the Heart, thus causing belching by moving upward to the Heart. Furthermore, it states: When Yangming and Jueyin disorders occur, the main symptoms include fright, back pain, frequent belching, and yawning.
[Zhang Zhongjing] Xuanfu Daizhe Tang (Inula and Hematite Decoction) treats palpitations accompanied by belching. (See this formula in the Palpitations section of Shanghan Lun.)
[Ben Cao Yan Yi or related texts] Accumulation and stagnation in the epigastrium causing distension or pain, often accompanied by belching with a smell of rotten eggs, is primarily treated with Zhike San (Citrus Aurantium Powder).
Zhike (Aurantium Fructus), Baizhu (Atractylodis Macrocephalae Rhizoma) (each 0.5 liang), Xiangfu (Cyperi Rhizoma) (1 liang), Binglang (Arecae Semen) (2 qian).
Grind into fine powder. Take 2 qian each time, mixed with rice water for administration. Take three times daily, without restriction on timing. (Formula from Old Man Pang.)
[Zhu Danxi] A patient from Xuanzhou had all symptoms resolved by the previous formula but felt Qi rushing upward to strike the heart and diaphragm region, with slight relief after belching. His pulse was weak and short at the Right Guan position, while the Left Guan and Left Chi positions were long, surging, large, and rapid. This indicates Heat in the Liver; treatment should involve draining Liver Heat and tonifying the Spleen.
Qingpi (Citri Reticulatae Pericarpium Viride) (1 qian), Baizhu (Atractylodis Macrocephalae Rhizoma) (2.5 qian), Mutong (Akebiae Caulis), Gancao (Glycyrrhizae Radix et Rhizoma) (2 fen).
Decoct and take with Baohé Wan (Preserve Harmony Pill) fifteen pills and Yiqing Wan (Suppress Green Pill) twenty pills.
Belching is caused by Fire and Phlegm in the Stomach.
Zhì Nánxīng (Prepared Arisaematis Rhizoma), Banxia (Pinelliae Rhizoma), Ruǎn Shí Gāo (Gypsum Fibrosum), Xiangfu (Cyperi Rhizoma).
Equal parts, decoct in water and take orally.
According to the Theory of Five Movements and Six Qi, there are three types of belching:
First, Heat assists Heart Excess causing belching. The Classic states: When Shaoyin Fire rebounds, belching and hiccups occur.
Second, Cold attacks Heart Deficiency causing belching. The Classic states: When Taiyang governs the year, excessive Cold leads to frequent belching. It also states: When Taiyang rebound occurs, clear fluid is spat out, along with hiccups and belching.
Third, Wind attacks Spleen Deficiency causing belching. It also states: When Jueyin is in the lower position, excessive Wind causes abdominal distension and frequent belching.
For acupuncture treatment of belching, exclusively select points from the Spleen meridian. The Classic states: When the Foot-Taiyin Spleen Meridian is disturbed, it causes abdominal distension and frequent belching; treat according to the excess or deficiency, heat or cold, and sinking conditions observed in the pulse.
[Zhang Zhongjing] The Cun Kou (Radial artery at the wrist) pulse is weak and slow. Weakness indicates insufficiency of Yang Qi; slowness indicates excess Stomach Qi (stagnation). Symptoms include belching, acid regurgitation, sudden inability to swallow food, and Qi blocking above the diaphragm.
[Mai Jing] A tight pulse at the Cun position indicates an Excess of Cold. With Cold in the Upper Jiao, the chest must be full and accompanied by belching. A faint and choppy pulse at the Fuyang position (posterior tibial artery) indicates no Stomach Qi (faint) and injured Spleen (choppy). If purgatives are incorrectly used when Cold is in the diaphragm, Cold accumulation persists, Stomach Qi becomes weak, and Spleen is injured. Grain Qi fails to circulate, leading to belching after eating. This is due to Cold in the chest and diaphragm, upper deficiency and lower excess, and blocked Grain Qi, resulting in a condition of obstruction. Both a faint and choppy Fuyang pulse and a tight Cun pulse with belching belong to Cold patterns. (Full text see Diagnosis sections.) In mid-stage TAIYIN disease, abdominal distension and constipation occur, accompanied by belching and vomiting/rebellious Qi.
