此由手少阳之络脉虚，为风邪所乘故也。手少阳之脉，起小指次指之端，上循入缺盆，
布中，散络心包。风邪在其经，邪气迫于心络，心气不得宣畅，故烦满；乍上攻于胸，或
下引于胁，故烦满而叉胸胁痛也。若经久，邪气留连，搏于脏则成积，搏于腑则成聚也。
水谷痢者，由体虚腠理开，血气虚，春伤于风，邪气留连在肌肉之内，后遇脾胃大肠虚
弱，而邪气乘之，故为水谷痢也。
脾与胃为表里，胃者，脾之腑也，为水谷之海；脾者，胃之脏也，其候身之肌肉。而脾
气主消水谷，水谷消，其精化为荣卫，中养脏腑，充实肌肤。大肠，肺之腑也，为传导之官
，变化出焉。水谷之精，化为血气，行于经脉，其糟粕行于大肠也。肺与大肠为表里，而肺
主气，其候身之皮毛。春阳气虽在表，而血气尚弱，其饮食居处，运动劳役，血气虚者，则
为风邪所伤，客在肌肉之间，后因脾胃气虚，风邪又乘虚而进入于肠胃，其脾气弱，则不能
克制水谷，故糟粕不结聚而变为痢也。
又新食竟取风，名为胃风。其状，恶风，头多汗，膈下塞不通，食饮不下，腹满，形瘦
腹大，失衣则 满，食寒则洞泄。其洞泄者，痢无度也，若胃气竭者，痢绝则死。
诊其脉微，手足寒，难治也；脉大，手足温，易治。下白沫，脉沉则生，浮则死。身不
热，脉不悬绝，滑大者生，悬涩者死，以脏期之也。脉绝而手足寒者死，脉还手足温者生，
脉不还者死。脉缓时小结生，洪大数者死。悬绝而涩者死，细微而涩者、紧大而滑者死，
得代绝脉者亦死。
《养生方》云∶秋三月，此谓容平。天气以急，地气以明，早卧早起，与鸡俱兴。使志
安宁，以缓秋刑。收敛神气，使秋气平。无外其志，使肺气精。此秋气之应也，养收之道也
。逆之则伤肺，冬为飧泄。
又云∶五月勿食未成核果及桃枣，发痈疖。不尔，发寒热，变黄胆，又为泄痢。
这是因为手少阳经的络脉虚弱，被风邪侵袭所致。手少阳经脉，起始于小指与无名指之间，向上沿行至缺盆穴，分布于胸中，散布并联络心包络。风邪停留在该经脉中，邪气逼迫心之络脉，导致心气不能宣通畅达，所以出现烦闷胀满；邪气有时向上攻冲至胸部，有时向下牵引至胁肋部，因此出现烦闷胀满以及叉按胸部、胁肋疼痛的症状。如果病程迁延日久，邪气滞留不去，搏结于脏则形成积证，搏结于腑则形成聚证。
水谷痢（大便中含有未消化的食物残渣），是由于体质虚弱、腠理疏松，气血不足，春季感受风邪，邪气留滞于肌肉之内，后来又遇到脾胃和大肠虚弱，邪气趁机侵入，从而形成水谷痢。
脾与胃互为表里，胃是脾的腑，是水谷汇聚的海洋；脾是胃的脏，其外在表现反映在身体的肌肉上。脾气的功能主要是消化水谷，水谷被消化后，其中的精华转化为营气和卫气，在中焦滋养脏腑，充实肌肤。大肠是肺的腑，负责传导糟粕，变化排泄物由此产生。水谷中的精微物质化为血气，运行于经脉之中，而剩下的糟粕则运行于大肠内。肺与大肠互为表里，肺主司气，其外在表现反映在身体的皮毛上。春季阳气虽然浮越于体表，但体内的气血尚且虚弱，如果饮食起居不当或过度劳役，导致气血亏虚，就会被风邪所伤，邪气客居于肌肉之间，随后因为脾胃之气虚弱，风邪又乘虚进入肠胃，脾气虚弱则不能制约水谷运化，导致糟粕不能成形积聚而变成痢疾。
另外，刚吃完饭后受风，称为“胃风”。其症状表现为：怕风，头部多汗，膈下堵塞不通，饮食难以下咽，腹部胀满，身体消瘦但腹部膨大，衣着单薄则腹胀加重，食用寒凉食物则发生洞泄（严重的水样腹泻）。所谓洞泄，是指痢疾无节制地发作，如果胃气衰竭，痢疾停止（正气绝）则死亡。
诊察脉搏微弱，手足寒冷，属于难治之症；脉搏洪大，手足温暖，容易治疗。大便排出白色泡沫，脉象沉伏则生，浮取则死。身体不发热，脉搏没有悬绝现象，脉象滑大者生，脉象悬涩者死，这是根据脏腑气机判断预后的方法。脉搏断绝且手足寒冷的死亡，脉搏恢复且手足温暖的生存，脉搏不复发的死亡。脉象缓和但偶尔细小结代的生存，脉象洪大数急的死亡。脉象悬绝且涩的死亡，脉象细微且涩的、紧大而滑的死亡，出现代脉（节律不齐，有规律间歇）且断绝的也死亡。
《养生方》说：秋季三个月，叫做容平（万物成熟收敛）。天气变得劲急，地气变得清明，应当早睡早起，与鸡鸣同时起床。使情志安宁，以缓解秋气的肃杀之刑。收敛神气，使秋气平和。不要使志意外驰，使肺气清精。这是顺应秋气的做法，是养护“收”的原则。违背它则会损伤肺脏，冬季发生飧泄（完谷不化的腹泻）。
又说：五月不要吃未成熟的果实以及桃子和枣子，否则会引发痈疽疖肿。如果不这样做，会引发寒热往来，转变为黄疸病，或者发生泄痢。
This condition arises from the deficiency of the collateral vessels of the Hand-Shaoyang (Triple Burner) meridian, which are invaded by Wind pathogen. The Hand-Shaoyang meridian originates at the tip between the little and ring fingers, ascends along to the Keyhole (Quepen, LI15) acupoint, distributes in the chest center, and scatters to connect with the Pericardium. When Wind pathogen resides in this meridian, the pathogenic qi presses upon the collateral vessels of the Heart, preventing the Heart qi from flowing freely and smoothly; thus, vexation and fullness occur. If the pathogen attacks upward to the chest or pulls downward to the hypochondrium, it causes vexation, fullness, and pain in the chest and hypochondrium that leads the patient to cross their arms over the chest. If the disease persists for a long time, the pathogen lingers and knots with the Zang organs to form "Ji" (accumulation masses), or knots with the Fu organs to form "Ju" (gathering masses).
Shuigu Di (Dysentery with undigested food) occurs due to physical weakness, open interstices (Couli), and deficiency of Blood and Qi. After being injured by Wind in spring, the pathogen remains lingering within the muscles. Later, when the Spleen, Stomach, and Large Intestine become weak, the pathogen takes advantage of this deficiency to invade, resulting in Shuigu Di.
The Spleen and Stomach are exterior-interior paired; the Stomach is the Fu organ of the Spleen and serves as the sea of water and grain; the Spleen is the Zang organ of the Stomach, and its manifestation reflects on the muscles of the body. The Spleen governs the digestion of water and grain. Once digested, the essence transforms into Ying (Nutritive) and Wei (Defensive) Qi, which nourish the Zang-Fu organs in the middle jiao and fill the muscles. The Large Intestine is the Fu organ of the Lung, serving as the official of transmission, where changes and excretion occur. The essence of water and grain transforms into Blood and Qi, circulating through the meridians, while the dregs travel through the Large Intestine. The Lung and Large Intestine are exterior-interior paired; the Lung governs Qi, and its manifestation reflects on the skin and hair. In spring, although Yang Qi floats to the exterior, the internal Blood and Qi are still weak. Improper diet, lifestyle, or excessive labor can lead to Blood and Qi deficiency, making one susceptible to Wind pathogen, which lodges in the muscles. Subsequently, due to Spleen-Stomach Qi deficiency, Wind pathogen invades the intestines and stomach. With weak Spleen Qi, the transformation and transportation of water and grain cannot be controlled, causing the dregs to fail to consolidate and instead becoming dysentery.
Furthermore, contracting Wind immediately after eating is called "Wei Feng" (Stomach Wind). Its symptoms include aversion to wind, profuse sweating on the head, blockage below the diaphragm, inability to swallow food and drink, abdominal fullness, emaciation of the body with a distended abdomen, worsening blooding when clothing is insufficient, and severe watery diarrhea (Dongxie) after consuming cold foods. Dongxie refers to uncontrolled dysentery/diarrhea; if Stomach Qi is exhausted and the dysentery stops (indicating the cessation of Zheng Qi), death ensues.
Diagnostically, a faint pulse with cold hands and feet indicates a difficult-to-treat case; a large pulse with warm hands and feet indicates an easy-to-treat case. Passage of white mucus/froth: a deep pulse suggests survival, while a floating pulse suggests death. Absence of fever and non-hanging-extreme pulse: a slippery and large pulse suggests survival, while a hanging and choppy pulse suggests death, based on the timing of Zang organ decline. Pulse extinction with cold hands and feet indicates death; pulse recovery with warm hands and feet indicates survival; failure of pulse recovery indicates death. A slow pulse with occasional small knotted beats suggests survival; a surging, large, and rapid pulse indicates death. A hanging and choppy pulse indicates death; a fine, minute, and choppy pulse, or a tight, large, and slippery pulse, indicates death. Appearance of Dai Mai (intermittent pulse) with extinction also indicates death.
The *Yangsheng Fang* states: The three months of autumn are called "Rong Ping" (Container and Level/Convergence). The heavenly Qi becomes urgent, and the earthly Qi becomes clear. One should sleep early and rise early, waking with the chickens. Keep the mind peaceful to mitigate the harshness of Autumn Qi. Converge the Shen (Spirit) to maintain balance with Autumn Qi. Do not let desires scatter outward, so that Lung Qi remains pure and refined. This is the response to Autumn Qi and the way of nurturing "Gathering." Violating this injures the Lungs, leading to Sun Xie (undigested stool diarrhea) in winter.
It also states: In the fifth month, do not consume unripe fruits, peaches, or dates, as they may trigger carbuncles and furuncles. Otherwise, they may cause alternating chills and fever, transform into Jaundice, or induce diarrhea and dysentery.
