六腑之华在唇。经云∶脾胃大肠小肠三焦膀胱者，仓廪之本，荣之居也，其华在唇四白是也。胃脉肝脉督
脉皆环唇。经云。胃足阳明之脉，挟口环唇。又云；肝足厥阴之脉环唇。《内经》云∶督脉上颐环唇是也。冲脉
任脉皆络唇。经云∶冲脉任脉别而络唇口是也。
唇反者死。经云∶唇舌肌者，肉之本也。唇反者，肉先死是也。
阳主四肢。经云∶四肢者，诸阳之本也。又云∶阳受气于四肢是也。阳实则肢肿。经云∶结阳肿四肢是也。
阳虚则肢满。经云∶冬气病在四肢是也。脾主四肢。经云∶四肢皆禀气于胃，而不得至经，必因于脾乃得禀者
是也。脾实则四肢不举。经云∶脾脉太过为病，在外则令人四肢不举者是也。脾虚则四肢不用。经云∶脾藏肉，
形不足，则四肢不用。又云∶四肢懈惰，此脾精之不行是也。（治见痿及中风。）五脏有邪，留在支节。经云∶
肺心有邪，其气留于两肘；肝有邪，其气留于两股；脾有邪，其气留于两髀；肾有邪，其气留于两膝是也。（治

六腑的精气外荣于口唇。《内经》说：脾胃、大肠、小肠、三焦、膀胱，是饮食仓廪的根本，营气所居之处，其精气外荣于口唇四周的白肉处，说的就是这种情况。足阳明胃经、足厥阴肝经和督脉都环绕口唇。经文说：足阳明胃经，夹着口部环绕嘴唇。又说：足厥阴肝经，环绕口唇。《黄帝内经》说：督脉上行至面颊并环绕口唇，说的就是这种情况。冲脉和任脉也都联络口唇。经文说：冲脉和任脉分支后联络口唇，说的就是这种情况。
口唇翻卷者主死证。经文说：舌和肌肉，是脾土之本。口唇翻卷，意味着脾土先败亡，说的就是这种情况。
阳气主宰四肢。经文说：四肢，是诸阳经的根本。又说：阳气受纳于四肢，说的就是这种情况。阳气实盛则肢体肿胀。经文说：阳气结聚于上部则四肢肿胀，说的就是这种情况。阳气虚衰则肢体胀满。经文说：冬季寒气致病多在四肢，说的就是这种情况。脾脏主宰四肢。经文说：四肢都禀受胃中的水谷精气，但精气不能直接到达经脉，必须通过脾脏的转输才能布达，说的就是这种情况。脾脏邪气实盛则四肢不能举动。经文说：脾脉太过导致的疾病，在体表表现为让人四肢不能举动，说的就是这种情况。脾脏精气虚衰则四肢不能使用。经文说：脾脏主管肌肉，形体虚弱不足，则四肢不能使用。又说：四肢懈怠懒惰，这是脾精不能运化的表现。（治疗方法见痿证及中风章节。）五脏若有邪气滞留，会停留在四肢关节。经文说：肺心有邪气，其气滞留在两肘；肝脏有邪气，其气滞留在两股；脾脏有邪气，其气滞留在两大腿根；肾脏有邪气，其气滞留在两膝，说的就是这种情况。（治疗方法见痛痹章节。）
五运六气方面：四肢不能举动，都属于湿邪所致。经文说：土运太过称为“敦阜”。敦阜之年，其病症为腹部胀满、四肢不能举动，说的就是这种情况。
〔《针灸甲乙经》〕风邪逆乱导致四肢肿胀，取复溜穴主治。
脾脏主管肌肉。经文说：脾脏主管肌肉，在形体表现为肌肉，在脏腑对应脾脏。又说：邪气侵犯脾胃，就会发生肌肉疼痛，说的就是这种情况。脾病的病位在溪。经文说：北方属黑色，内通于肾脏，所以疾病发生在溪。所谓“溪”，是指肌肉之间的小交会处。
〔《黄帝内经·素问》〕黄帝问：希望听听溪谷交会的情况？岐伯回答：肌肉的大交会处称为“谷”，肌肉的小交会处称为“溪”。在肌肉分理之间，溪谷交会之处，用来运行营卫之气，汇聚大气。如果邪气充溢、正气壅滞，脉道发热、肌肉败坏，营卫之气运行不畅，必将化生脓液，向内侵蚀骨髓，向外破溃大肌腠，留滞在关节节凑，必将导致败坏。若寒邪积聚停留，营卫之气无法安居，会导致肌肉卷缩、筋脉拘挛，胁肋和肘部不能伸展，在内形成骨痹，在外表现为肌肤麻木不仁，这被称为“不足”，是大寒邪气留滞在溪谷所致。全身三百六十五个穴位交会于溪谷，也对应一年的天数。对于轻微的风湿痹症，邪气淫溢，沿着经脉往来流动，微针可以触及治疗，其法则与此相同。（出自《气穴论》）
形体安逸、情志愉悦，疾病产生于肌肉，用针石治疗。（全文详见治疗方法章节。）
湿邪伤害肌肉，甘味过度也会伤害肌肉。经文说：湿邪伤害肌肉，风胜湿，甘味伤害肌肉，酸味胜甘味。又说：甘味走肌肉，患有肌肉病时不要多吃甘味食物。又说：多吃酸味食物会导致肌肉角质增厚且口唇干裂揭皮，说的就是这种情况。久坐伤肉。经文说：久坐伤害肌肉。又说：形体安逸、情志愉悦，疾病产生于肌肉，用针石治疗，说的就是这种情况。
(Entered into the Middle Xiao Section)
(Entered into the Mouth Ulcer Section, Lip Sour Entry)
The brilliance of the Six Fu Organs manifests in the lips. The Classics state: The Spleen, Stomach, Large Intestine, Small Intestine, Sanjiao (Triple Burner), and Bladder are the root of the granary and the residence of Ying Qi (Nutritive Qi); their brilliance manifests in the white flesh around the lips. This is what is meant. The Stomach Meridian of Foot-Yangming, Liver Meridian of Foot-Jueyin, and Du Mai (Governing Vessel) all circle the lips. The Classics say: The Foot-Yangming Stomach Meridian runs alongside the mouth and circles the lips. It also says: The Foot-Jueyin Liver Meridian circles the lips. The *Neijing* states: The Du Mai ascends to the chin and circles the lips; this is what is meant. The Chong Mai (Penetrating Vessel) and Ren Mai (Conception Vessel) both connect with the lips. The Classics say: The Chong Mai and Ren Mai branch off to connect with the mouth and lips; this is what is meant.
Lip eversion indicates a fatal condition. The Classics state: The tongue and muscles are the root of flesh. Lip eversion means the flesh (Spleen Earth) dies first; this is what is meant.
Yang governs the four limbs. The Classics state: The four limbs are the root of all Yang meridians. It also says: Yang Qi receives nourishment in the four limbs; this is what is meant. When Yang is excess, limbs swell. The Classics state: Yang qi stagnation causes swelling in the four limbs; this is what is meant. When Yang is deficient, limbs feel full/distended. The Classics state: In winter, diseases affect the four limbs; this is what is meant. The Spleen governs the four limbs. The Classics state: The four limbs all receive Qi from the Stomach, but cannot reach the meridians directly; they must rely on the Spleen to distribute it; this is what is meant. When Spleen is excess, the four limbs cannot move. The Classics state: Excessive Spleen meridian pulse causes disease, manifesting externally as inability to move the four limbs; this is what is meant. When Spleen is deficient, the four limbs lose function. The Classics state: The Spleen stores flesh; when the form is insufficient, the four limbs lose function. It also says: Limb lassitude and inactivity indicate that Spleen Jing (Essence) is not circulating. (Treatment seen in Wei Syndrome and Stroke sections.) When the Five Zang Organs have pathogenic factors lingering, they remain in the branches and joints. The Classics state: If Lung or Heart have pathogens, their Qi remains in the two elbows; if Liver has pathogens, their Qi remains in the two thighs; if Spleen has pathogens, their Qi remains in the two hips/thigh roots; if Kidney has pathogens, their Qi remains in the two knees; this is what is meant. (Treatment methods seen in Painful Bi Syndrome sections.)
Regarding Yunqi (Five Movements and Six Qi): Inability to move the four limbs all belongs to Dampness. The Classics state: Excess Earth movement is called "Dunfu" (Mound-like). In the era of Dunfu, its diseases include abdominal fullness and inability to move the four limbs; this is what is meant.
[From *Jia Yi Jing*]: Wind counterflow causing limb swelling is primarily treated by Fuliou (KI7).
The Spleen governs flesh/muscles. The Classics state: The Spleen governs flesh; in the body it is flesh, in the organs it is the Spleen. It also says: Pathogens in the Spleen and Stomach cause muscle pain; this is what is meant. Spleen disease locates in the "Xi" (valleys/grooves between muscles). The Classics state: North corresponds to Black, entering internally to connect with the Kidney, thus disease occurs in the Xi. Xi refers to the small intersections of flesh.
[From *Suwen*]: The Yellow Emperor asked: I wish to hear about the convergence of Xi and Gu. Qibo replied: The large convergence of muscles is called Gu; the small convergence of muscles is called Xi. Between muscle divisions, at the convergence of Xi and Gu, Ying Qi and Wei Qi (Defensive Qi) circulate, and Da Qi (Great Qi) gathers. If pathogens overflow and Qi becomes stagnant, pulses become hot and flesh decays, Ying and Wei Qi fail to circulate, pus will inevitably form, dissolving marrow internally and breaking large muscle layers externally. Remaining at the joint crevices, it will inevitably lead to decay. If cold accumulates and stays, Ying and Wei Qi cannot reside, muscles curl and tendons contract, ribs and elbows cannot extend, internally forming Bone Bi, externally manifesting as numbness/insensitivity. This is called "Insufficiency," where Great Cold remains in the Xi and Gu. There are 365 points converging in Xi and Gu, corresponding to the days of a year. For minor Bi syndromes with overflowing pathogens moving along meridians, fine needles can reach them, following the same principles. (From *Qi Xue Lun*)
When form is comfortable and mind is joyful, diseases arise in the flesh, treated with acupuncture and stone needles. (Full text seen in Treatment Methods section.)
Dampness injures flesh; Sweet flavor injures flesh. The Classics state: Dampness injures flesh, Wind overcomes Dampness, Sweet flavor injures flesh, Sour flavor overcomes Sweet. It also says: Sweet flavor travels to flesh; for flesh diseases, do not eat much sweet food. It also says: Eating too much sour leads to calloused flesh and peeling lips; this is what is meant. Sitting for long periods injures flesh. The Classics state: Long sitting injures flesh. It also says: When form is comfortable and mind is joyful, diseases arise in the flesh, treated with acupuncture and stone needles; this is what is meant.
