噫醋者，由上焦有停痰，脾胃有宿冷，故不能消谷，谷不消则胀满而气逆，所以好噫而
吞酸，气息醋臭。
恶心者，由心下有停水积饮所为也。心主火，脾主土，土性克水，今脾虚则土气衰弱，
不能克消水饮，水饮之气不散，上乘于心，复遇冷气所加之，故令火气不宣，则心里澹澹然
欲吐，名为恶心也。
宿食不消，由脏气虚弱，寒气在于脾胃之间，故使谷不化也。宿谷未消，新谷又入，脾
气既弱，故不能磨之，则经宿而不消也。令人腹胀气急，噫气醋臭，时复憎寒壮热是也，或
头痛如疟之状。
寸口脉浮大，按之反涩，尺脉亦微而涩者，则宿食不消也。其汤熨针石，别有正方，补
养宣导，今附于后。
《养生方·导引法》云∶凡食讫，觉腹内过饱，肠内先有宿气，常须食前后，两手撩膝
，左右欹身，肚腹向前，努腰就肚，左三七，右二七，转身按腰脊极势。去太仓腹内宿气不
化、脾痹肠瘦、脏腑不和。得令腹胀满，日日消除。
又云∶闭口微息，正坐向王气，张鼻取气，逼置齐下，小口微出气十二通，以除结聚，
低头不息十二通，以消饮食，令身轻强，行之，冬月不寒。
又云∶端坐伸腰，举左手，仰掌，以右手承右胁，以鼻纳气，自极七息，除胃中寒食不
消。
又云∶端坐伸腰，举右手，仰掌，以左手承左胁。以鼻纳气，自极七息。所除胃寒，食
不变，则愈。
又云∶ 行气，低头倚壁，不息十二通。以意排之，痰饮宿食从下部出，自愈。 行气
者，身直颈曲，排气下行十二通，愈宿食。
又云∶雁行气，低臂推膝踞，以绳自缚拘左，低头倚臂，不息十二通。消食轻身，益精
神，恶气不入，去万邪。一本云∶正坐，仰天，呼吸天精，解酒食饮饱。出气吐之数十，须
臾立饥且醒。夏月行之，令人清凉。
噫气吞酸，是由于上焦有痰饮停滞，脾胃有陈寒积冷，因此不能消化谷物。谷物不消化则导致腹部胀满、气机上逆，所以容易打嗝并伴有吞酸，呼出的气息带有醋样的酸臭味。
恶心，是由于心下（胃脘部）有水饮停聚所致。心属火，脾属土，土的属性本应克制水，如今脾虚则土气衰弱，不能制约和消除水饮，水饮之气不散，上乘于心，再加上受到冷气的侵袭，导致心火之气不能宣通，心中悸动不安想要呕吐，这称为恶心。
宿食不消，是由于脏腑之气虚弱，寒气停留在脾胃之间，致使谷物无法消化。未消化的宿食尚未排空，新的食物又进入体内，脾气既然虚弱，就不能磨化食物，因此经过一夜也不能消化。这会导致腹部胀满、呼吸急促、打嗝且气息酸臭，有时还伴有怕冷和高热，或者头痛如同疟疾发作时的症状。寸口脉象浮大，重按反而涩滞，尺脉也微弱而涩，这是宿食不消的脉象。对于此类病症，汤药、熨法、针刺、砭石等治疗另有专门方剂，补养和导引疗法，现附在后面。
《养生方·导引法》说：凡是吃完饭后，感觉腹内过于饱胀，肠道内先有滞留之气，常在进食前后，双手托住膝盖，身体向左右倾斜，腹部向前挺出，腰部用力贴近腹部，左侧做二十一次（三七），右侧做十四次（二七），转身按摩腰脊至极限。这样可以去除太仓（胃）内的宿气不化、脾痹、肠瘦以及脏腑不和。能使日渐消除腹胀满的症状。
又说：闭口微微呼吸，端正坐姿面向王气（方位），张开鼻孔吸气，将气逼至脐下，小口微呼气十二次，以消除气结郁聚；低头屏息十二次，以消化饮食，使身体轻健有力，坚持练习，冬季也不受寒。
又说：端正坐好伸直腰，举起左手，手掌向上，用右手托住右胁，用鼻子吸气，直至极限共七次呼吸，可以去除胃中的寒气和食物不消化。
又说：端正坐好伸直腰，举起右手，手掌向上，用左手托住左胁。用鼻子吸气，直至极限共七次呼吸。所去除的是胃寒，如果食物不变质不消化，通过此法即可痊愈。
又说：行气时，低头倚靠墙壁，屏息十二次。用意念引导，使痰饮、宿食从下部排出，自然痊愈。行气者，身体挺直颈部弯曲，使排气下行十二次，可治愈宿食。
又说：雁行气，降低手臂推膝蹲踞，用绳子束缚固定左脚，低头倚靠手臂，屏息十二次。可以消食轻身，益精神，防止恶气侵入，去除各种邪气。另一版本说：端正坐好，仰视天空，呼吸天地精气，解除酒食饱胀。呼气数十次，片刻之后就会感到饥饿且清醒。夏季练习，使人感到清凉。
Belching with acid regurgitation is caused by the retention of phlegm-fluids in the Upper Jiao (Upper Burner) and chronic cold accumulation in the Spleen and Stomach, which prevents the digestion of grains. When grains are not digested, it leads to abdominal distension and rebellious Qi movement, resulting in frequent belching and acid regurgitation, with breath that smells sour like vinegar.
Nausea is caused by the accumulation of water and fluids below the heart (epigastric region). The Heart governs Fire, and the Spleen governs Earth; the nature of Earth is to control Water. However, when the Spleen is deficient, the Qi of Earth becomes weak and fails to control and resolve the water and fluids. The Qi of these accumulated fluids rises upward to affect the Heart. Furthermore, if aggravated by cold pathogenic factors, the Qi of Fire cannot circulate freely, causing palpitations and a sensation of wanting to vomit within the chest, which is termed nausea.
Undigested food retention is due to the weakness of Zang-Fu organ Qi and the presence of cold pathogens between the Spleen and Stomach, preventing the digestion of food. When undigested old food remains and new food enters, the weakened Spleen Qi cannot grind and transform it, leading to retention overnight. This manifests as abdominal distension, shortness of breath, belching with sour-smelling breath, sometimes accompanied by aversion to cold and high fever, or headache resembling malaria. If the Cun Kou pulse (Radial artery at the wrist) is floating and large but feels choppy upon deep pressure, and the Chi pulse (distal radial artery) is also faint and choppy, this indicates undigested food retention. For such conditions, decoctions, moxibustion/warming therapies, acupuncture, and stone therapy have separate specific formulas. Nourishing and Daoyin (guiding and pulling) exercises are attached hereafter.
The *Yangsheng Fang* (Prescriptions for Nurturing Life) · *Daoyin Fa* (Guiding and Pulling Methods) states: After eating, if one feels overly full in the abdomen and there is stagnant Qi in the intestines, one should perform these exercises before and after meals. Place both hands on the knees, lean the body left and right, push the abdomen forward, exert force with the waist towards the abdomen, do 21 repetitions (3 times 7) on the left side and 14 repetitions (2 times 7) on the right side, then turn and massage the lower back and spine to the limit. This removes stagnant Qi from the Tai Cang (Stomach), treats Pi Bi (Spleen Bi syndrome), Chang Shou (intestinal wasting), and disharmony of the Zang-Fu organs. It helps eliminate daily abdominal distension.
It further states: Close the mouth and breathe slightly, sit upright facing the "Wang Qi" direction, open the nostrils to inhale, guide the Qi down to the umbilical region, exhale slightly through small puffs twelve times to resolve Qi stagnation; bow the head and hold the breath twelve times to digest food, making the body light and strong. Practicing this in winter prevents cold.
It further states: Sit upright with the spine straight, raise the left hand with palm up, support the right hypochondrium with the right hand, inhale through the nose until the limit for seven breaths. This eliminates cold and indigestion in the Stomach.
It further states: Sit upright with the spine straight, raise the right hand with palm up, support the left hypochondrium with the left hand. Inhale through the nose until the limit for seven breaths. This resolves Stomach cold; if food is not transformed or digested, this method will lead to recovery.
It further states: During Qi circulation, bow the head and lean against a wall, hold the breath twelve times. Use intention to guide Phlegm-Fluids and undigested food out from the lower part, leading to spontaneous recovery. For Qi circulation practitioners, keep the body straight and neck curved, allowing expelled Qi to descend twelve times to cure undigested food.
It further states: "Goose-like Qi circulation": Lower arms, push knees, squat, bind the left foot with a rope, bow head leaning on arm, hold breath twelve times. This aids digestion, lightens the body, benefits Essence and Spirit, prevents evil Qi from entering, and removes myriad pathogens. Another version states: Sit upright, look up at the sky, breathe in Heaven's essence, relieve drunkenness and food fullness. Exhale dozens of times; soon one will feel hungry and awake. Practicing this in summer brings a cooling sensation.
