胃是六腑之一，又被称为“水谷之海”，与脾互为表里，是人体生命的根本。胃气强健，则五脏六腑都强健；足阳明胃经是其所属的经脉。如果胃气断绝，五天后就会死亡。胃实证表现为腹部肿胀、排便困难、肢体关节疼痛、无法进食、持续呕吐。胃虚证表现为肠鸣、腹胀满、出汗且滑泄不禁。胃寒证表现为腹中疼痛、不能食用生冷食物。胃热证表现为面色红赤像喝醉的人、四肢无力下垂、夜晚睡眠不安、言语狂妄、目光混乱、大便干硬。疼痛严重时出现腹部和胁肋部胀满、呕吐导致无法进食。心窝上下气机不通畅、厌恶食物的气味、讨厌别人说话、发冷颤抖、喜欢伸懒腰打哈欠。胃中有热则嘴唇发黑，热势极盛则登高唱歌、脱衣奔跑、精神错乱不定、额头出汗、鼻出血不止。胃虚则四肢浮肿胀满、胸部气息短促、食物不消化而消瘦。风邪侵入胃则导致腹泻不止，胃气不足则容易饥饿但食物不消化，病人如果胃气不平且伴有口渴症状的，难以治愈。胃脉坚硬而长，面色黄赤，病在腰部折断样疼痛；胃脉软弱而散，病为饮食停滞痹阻。关部脉象浮大的属于虚证，浮而短涩的属于实证；浮而微滑的也属虚证，浮而迟缓的属寒证，浮而数动的属热证。虚实寒热以及生死预后的证候，通过诊察脉理，就能达到神妙境界。
大肠是肺的腑，负责传导功能，号称“监仓之官”。肺病日久会传入大肠，手阳明大肠经是其所属的经脉。大肠受寒则腹泻，受热则便秘结滞，大肠气绝则下利不止而死。热邪极盛则便血。风邪侵入大肠也会导致下血。实热证表现为腹部胀满、大便不通。虚寒证表现为滑泄无度。大肠有时虚有时实，症状时来时去，受寒则大便稀溏，受热则排泄污秽之物，有积滞物则发热战栗并怕冷，发作时口渴像疟疾一样，积冷导致痹痛，不能久站，疼痛停止后则腹泻，这些是有积滞物的表现。虚证表现为喜欢胀满、咳嗽气喘、咽喉中有异物感如核阻塞。
The Stomach is a Fu-organ, also known as the "Sea of Water and Grain," exteriorly-interiorly related to the Spleen, serving as the root of human life. When Stomach Qi is robust, all Zang and Fu organs are robust; the Foot-Yangming Meridian is its channel. If Stomach Qi ceases, death occurs within five days. Excess patterns manifest as abdominal distension and swelling, difficulty in defecation, pain in limbs and joints, inability to eat, and incessant vomiting. Deficiency patterns manifest as borborygmus, abdominal fullness, sweating with slippery incontinence. Cold patterns manifest as abdominal pain and inability to consume cold foods. Heat patterns manifest as a red face resembling intoxication, flaccidity of the four limbs, restless sleep at night, delirious speech, chaotic vision, and hard stools. Severe pain leads to abdominal and hypochondriac distension, and vomiting that prevents food intake. Obstruction of Qi flow above and below the epigastrium, aversion to the smell of food, dislike of people speaking, chills with trembling, and a desire to stretch and yawn. Heat in the Stomach causes black lips; extreme heat leads to climbing high and singing, discarding clothes and running, erratic mania, sweating on the forehead, and unceasing epistaxis. Deficiency leads to edema and fullness of the four limbs, shortness of breath in the chest, and emaciation due to undigested food. Wind invading the Stomach causes incessant loose stools; insufficiency of the Stomach leads to frequent hunger without digestion of food. If a patient has disharmonious Stomach Qi accompanied by thirst, it is incurable. A Stomach pulse that is firm and long, with a yellow-red complexion, indicates disease in the waist resembling a break; a soft and scattered pulse indicates food stagnation Bi-syndrome. A floating and large pulse at the Guan position indicates deficiency; a floating, short, and choppy pulse indicates excess; a floating and slightly slippery pulse also indicates deficiency; a floating and slow pulse indicates Cold; a floating and rapid pulse indicates Heat. By examining the pulse principles, the patterns of excess/deficiency, Cold/Heat, and life/death prognosis can be discerned with divine efficacy.
The Large Intestine is the Fu-organ of the Lung, responsible for transmission, titled the "Official of Surveillance." Long-standing Lung disease transmits to the Large Intestine; the Hand-Yangming Meridian is its channel. Cold causes diarrhea; Heat causes constipation and binding; cessation of Qi leads to incessant purging and death. Extreme Heat causes bloody stool. Wind invading the Large Intestine also causes lower bleeding. Excess-Heat manifests as distension and fullness with obstruction of defecation. Deficiency-Cold manifests as indefinite slippery incontinence. The Large Intestine alternates between deficiency and excess, with symptoms coming and going. Cold causes loose stools; Heat causes foul discharge. Accumulated pathogenic factors cause fever with shivering and aversion to cold, thirst resembling malaria-like attacks, accumulation of Cold causing Bi-pain, inability to stand for long periods, and diarrhea after pain subsides; these indicate accumulated matter. Deficiency manifests as a preference for fullness, coughing and wheezing, and a sensation of a foreign body like a pit obstructing the throat.
