胃者，脾之腑也，又名〔水〕谷之海，与脾为表里。胃者，人之根本，胃气壮，
则五脏六腑皆壮（也），足阳明是其经也。胃气绝，五日死。实则中胀便难，肢节痛，
不下食，呕逆不已。虚则肠鸣胀满，滑泄。寒则腹中痛，不能食〔冷〕物。热则面
赤如醉人，四肢不〔收〕持，不〔得〕安眠，语狂HT 乱，便硬者是也。病甚则腹胁胀满，
呕逆不食，当心痛，（下上）不〔通〕，恶闻香臭，嫌人语，振寒，善欠伸。胃
中热，〔则〕唇黑；热甚，则登高而歌，弃衣而走，颠狂不定，汗出额上，鼽〔衄〕
不止。虚极则四肢肿满，胸中短气，谷不化，中满也。胃中风，则溏泄不已；胃不
足，则多饥，不消食。病患鼻下平，则胃中病，渴者可治。胃脉搏坚而长，其色
〔黄赤者，当病折髀〕。其脉弱而散者，病食〔痹〕。右关上浮而大者，虚也；
浮而短涩者，实也；浮而微滑者，亦〔实〕也；浮而迟者，寒也；浮而数者，热也。
此胃〔腑〕虚实寒热，生死逆顺脉证之法也。
《主治备要》云∶是动则病〔凄沧〕振寒，善〔呻〕数欠，颜黑，病至则恶人与
火，闻木声则惕然而惊，心欲动，〔独〕闭户〔塞牖而〕处，甚则登高而歌，弃衣而走，
贲响腹胀，是为 厥。《脉诀》云∶右关上，脾胃脉之所出也，先以轻手得之，是胃，
属表；后以重手得之，是脾，属里。脾合肌肉，脾脉循肌肉而行，持脉指法，如九菽之
重，按至肌肉，脉道如微风轻扬柳梢者为缓；又稍稍加力，脉道敦实者为大，此为缓
大，脾家不病〔脉〕之状也。脾脉本部在肌肉，若出于肌肉之上，见于皮毛之间者，
是其浮也；入于肌肉之下，见于筋骨之分者，是其沉也。
胃，是脾的腑，又被称为“水谷之海”，与脾互为表里。胃，是人的根本，胃气强壮，那么五脏六腑都强壮（也），足阳明胃经是其所属经脉。胃气断绝，五日后死亡。胃实证表现为腹部胀满、大便困难、肢体关节疼痛、不能进食、呕吐逆气不止。胃虚证表现为肠鸣、腹胀满、滑泄（腹泻）。胃寒证表现为腹中疼痛、不能吃冷物。胃热证表现为面色红赤像喝醉的人、四肢无力支撑、无法安睡、言语狂妄错乱、大便干硬等。病情严重时出现腹部和胁部胀满、呕吐逆气不能进食、心窝部疼痛、上下不通畅、厌恶闻气味、讨厌别人说话、发冷颤抖、喜欢打哈欠伸懒腰。胃中有热，（则）嘴唇发黑；热势严重，则爬上高处唱歌、扔掉衣服奔跑、癫狂不定、额头出汗、鼻出血不止。极度虚弱时出现四肢肿胀、胸中气短、食物不消化、脘腹胀满。胃受风邪，则腹泻不止；胃气不足，则容易饥饿但食物不消化。病人鼻子下方平坦，说明胃中有病，口渴的可以治疗。胃脉搏动坚实而长，面色黄赤的，应当患髋部骨折痛（折髀）。脉象弱而散的，患饮食停滞之痹证。右关部脉浮而大的，是虚证；浮而短涩的，是实证；浮而微滑的，也是实证；浮而迟缓的，是寒证；浮而数快的，是热证。这是判断胃腑虚实寒热及生死顺逆的脉证法则。
《主治备要》说：本经发生病变则出现寒冷战栗、喜欢呻吟、频繁打哈欠、面色发黑，发病时厌恶人和火，听到木器声音就惊恐不安，心中悸动，（独自）关门闭窗居住，严重时爬上高处唱歌、扔掉衣服奔跑、腹中雷鸣胀满，这称为厥证。《脉诀》说：右关部是脾胃脉发出的部位，先用轻手触诊得到的是胃脉，属表；后用重手触诊得到的是脾脉，属里。脾合肌肉，脾脉沿着肌肉运行，切脉指法，如九颗豆子的重量，按至肌肉，脉道像微风轻轻吹动柳梢那样柔和为缓脉；再稍稍加力，脉道敦实有力为大脉，这就是缓大脉，是脾家没有生病的脉象状态。脾脉的本部在肌肉，如果脉象出于肌肉之上，显现在皮毛之间，这是浮脉；如果脉象进入肌肉之下，显现在筋骨之间，这是沉脉。
The Stomach is the Fu-organ of the Spleen, also known as the "Sea of Water and Grain," and stands in exterior-interior relationship with the Spleen. The Stomach is the root of human life; when Stomach Qi (Vital Energy) is robust, all Zang-fu organs are robust. The Foot-Yangming Meridian belongs to it. If Stomach Qi is exhausted, death occurs after five days. In excess conditions, there is abdominal distension, difficult defecation, pain in limbs and joints, inability to eat, and incessant vomiting and regurgitation. In deficiency conditions, there is borborygmus, abdominal fullness, and loose stools. In cold conditions, there is abdominal pain and inability to consume cold foods. In heat conditions, the face is red like a drunkard, limbs are weak and unable to support the body, sleep is restless, speech is delirious and chaotic, and stool is hard. When the disease is severe, there is distension of the abdomen and hypochondrium, vomiting and regurgitation with inability to eat, pain in the epigastrium, obstruction of upper and lower passages, aversion to odors, dislike of people's speech, chills, and frequent yawning and stretching. Heat in the Stomach causes black lips; severe heat causes climbing high to sing, discarding clothes and running, erratic mania, sweating on the forehead, and incessant epistaxis. Extreme deficiency causes swelling and fullness of the four limbs, shortness of breath in the chest, undigested food, and central fullness. Wind invading the Stomach causes incessant loose stools; insufficient Stomach Qi causes frequent hunger but indigestion. If the area below the patient's nose is flat, it indicates disease in the Stomach; if accompanied by thirst, it is treatable. A Stomach pulse that is firm and long, with a yellowish-red complexion, indicates disease of the hip (fracture or pain). A pulse that is weak and scattered indicates Bi-syndrome due to food stagnation. At the Right Guan position, a floating and large pulse indicates deficiency; floating and short/rough indicates excess; floating and slightly slippery also indicates excess; floating and slow indicates cold; floating and rapid indicates heat. These are the methods for determining the excess-deficiency, cold-heat, life-death, and favorable-unfavorable patterns of the Stomach Fu-organ based on pulse and symptoms.
"Zhu Zhi Bei Yao" states: When this meridian is affected, there is shivering chills, frequent groaning and yawning, dark facial color. Upon onset, there is aversion to people and fire, and startle upon hearing wooden sounds. The heart feels agitated, and the patient closes doors and windows to stay alone. Severe cases involve climbing high to sing, discarding clothes and running, rumbling and distension of the abdomen, which is termed Jue syndrome. "Mai Jue" states: The Right Guan position is where the Spleen and Stomach pulses emerge. Light pressure yields the Stomach pulse, which belongs to the Exterior; heavy pressure yields the Spleen pulse, which belongs to the Interior. The Spleen governs muscles, and its pulse runs along the muscles. For palpation technique, using the weight of nine beans, pressing to the muscle level, a pulse that flows gently like willow tips in a breeze is a Slow (Huan) pulse; adding slight force, a solid and substantial pulse is a Large (Da) pulse. This Slow-Large combination represents the normal pulse state of a healthy Spleen. The Spleen pulse originates in the muscles; if it appears above the muscles, between the skin and hair, it is a Floating (Fu) pulse; if it sinks below the muscles, appearing at the level of sinews and bones, it is a Deep (Chen) pulse.
