足太阴脾经图
脾脏之图
遗篇《刺法论》说：脾是谏议之官，智慧周遍由此产生。滑寿（滑氏）说：脾覆盖在胃（太仓）之上。华佗（华元化）说：脾主管消化五谷，滋养身体四周。中梓说：脾胃属土，都从“田”字而来，胃居于正中，“田”字也是居中，脾位于右侧，“田”字的撇也偏向右边。
《难经》说：脾重二斤三两，宽扁三寸，长五寸，还有一块半斤重的散膏，主要功能是包裹血液，温煦五脏。
足太阴脾经·脾：脾是仓廪之官，五味由此化生，是营气居住的地方。脾主藏意与智，主管全身的肌肉，是五脏的根本。心火为脾之母，肺金为脾之子。脾克制肾水，脾被肝木所贼（乘）。脾的精华中显露于口唇四周，其充养组织在肌肉。脾位居中央，对应的时间是长夏，脉象缓，颜色黄，音律为宫，成数为五，气味香，声音表现为歌，味道甘，厌恶湿气，体液为涎。在五行中属土。脾的外窍通于口，形态宽三寸，长五寸，覆盖并候察于胃（太仓），附着于脊柱第十一椎，与胃互为表里。脾经多气少血，巳时气血灌注于此。脾经气不足则气短，有余则胀满。平人脉象缓，病脉弦。脾病死于甲乙日。对应的牲畜是牛，对应的谷物是稷，天上对应的是镇星（土星）。
脾经的证候表现有：五种泄泻，大小便闭塞，面色黄，舌根强硬，口中有甜味，进食后呕吐，胃脘痛，腹胀肠鸣，容易嗳气且易饥；排便后余气排出则感觉舒畅，身体四肢倦怠，食物难以下咽，心烦，心下急痛，寒疟，溏瘕泄（大便稀薄夹杂未消化食物或肿块），小便不通，黄疸，不能平卧，强行站立，大腿和膝盖内侧肿胀，足大趾活动不利。饮食不节和劳倦会损伤脾。实证时梦见欢乐歌唱快乐，虚证时梦见因饮食而争斗。思虑过度伤脾，愤怒可以克制思虑；湿邪伤肌肉，风邪可以克制湿邪；甘味伤肌肉，酸味可以克制甘味。甘味走肌肉，肌肉有病不要多吃甘味食物。多吃酸味，则肌肉角质增厚而嘴唇掀揭。
脾经的经脉，起始于足大趾末端的隐白穴，接受足阳明胃经的气血交接。从此沿着大趾内侧白肉际的大部穴，经过核骨后方，依次经过太白、公孙、商丘穴，上行至内踝前缘的二阴交穴，再上行至小腿内侧，沿胫骨后方的漏谷穴，上行两寸，出于足厥阴肝经中都穴的前方，到达地机、阴陵泉穴；从阴陵泉穴向上沿膝骨内侧前缘，经过血海、箕门穴蜿蜒进入腹部，经过冲门、府舍穴，与任脉的中极、关元穴交会，又沿腹结、大横穴，与任脉的下脘穴交会；经过腹哀穴，经过足少阳胆经的日月穴、足厥阴肝经的期门穴，又沿本经腹哀穴的内侧，下行至任脉的中脘、下脘穴之间，归属于脾并联络于胃。再从腹哀穴向上穿过膈肌，沿食窦、天溪、胸乡、周荣穴，从周荣穴向外，曲折向下至大包穴，从大包穴向外曲折向上，与肺经的中府穴交会，上行至胃经人迎穴的内侧，挟持咽喉连接舌根，散布于舌底而终止；其支脉，沿腹哀穴行至胃部，与任脉的中脘穴外侧交会，向上穿过膈肌，注入任脉膻中穴的内侧，并与手少阴心经交会，接续自极泉穴下行而来的经脉。

The lost chapter "Ci Fa Lun" (Treatise on Acupuncture Methods) states: The Spleen is the official of admonition and discussion, from which wisdom and comprehensive knowledge arise. Hua Shou (Shi Shi) stated: It covers the Tai Cang (Stomach). Hua Tuo (Hua Yuanhua) stated: The Spleen governs the digestion of the five grains and nourishes the four sides of the body. Zhong Zi stated: The Spleen and Stomach belong to Earth; both characters contain the radical 'field' (Tian). The Stomach is situated in the center, just as the character 'field' is centered; the Spleen is located on the right, just as the stroke in the character 'field' leans to the right.
The Nan Jing (Classic of Difficult Issues) states: The Spleen weighs two jin and three liang, is broad and flat with a width of three cun and a length of five cun, and includes a half-jin of loose pancreas (San Gao). Its main function is to envelop blood and warm the five Zang organs.
Foot-Taiyin Spleen Meridian - Spleen: The Spleen is the official of granaries, from which the five flavors emerge. It is the residence of Ying (Nutritive) Qi. It stores Yi (Intellect/Thought) and Zhi (Wisdom), governs the muscles of the entire body, and serves as the root of the five Zang organs. Heart Fire is its Mother, Lung Metal is its Child. It controls Kidney Water, and Liver Wood attacks it. Its brilliance manifests in the four white areas around the lips, and its tissue fillment is in the muscles. Its position is Central, corresponding to the season of Late Summer, pulse is Huan (Slow/Relaxed), color is Yellow, musical note is Gong, number is Five, odor is Fragrant, sound is Song (Singing), taste is Gan (Sweet), and it dislikes Dampness. Its fluid is Xian (Saliva). In the Five Elements, it belongs to Earth. Its external orifice connects to the mouth. Its shape is three cun wide and five cun long, covering and observing the Tai Cang (Stomach), attached to the eleventh thoracic vertebra of the spine, forming an interior-exterior relationship with the Stomach. This meridian has abundant Qi and little Blood; Qi and Blood flow into it during the Si hour (9-11 AM). Deficiency leads to shortness of breath; excess leads to distension and fullness. A healthy pulse is Huan; a pathological pulse is Xian (Wiry). Disease of the Spleen may lead to death on Jia-Yi days. Its associated animal is the Ox, grain is Ji (Millet), and celestial body is Zhen Xing (Saturn).
Manifestations of Spleen meridian disorders include: five types of diarrhea, constipation of stool and urine, yellow complexion, stiffness of the tongue root, sweet taste in the mouth, vomiting after eating, epigastric pain, abdominal distension with borborygmus, frequent belching and hunger; relief felt after passing residual gas, fatigue and lassitude of the body and limbs, difficulty swallowing, vexation, acute pain below the heart, cold malaria, loose stools with undigested food or masses (Tan Jia), urinary obstruction, jaundice, inability to lie down, weakness when standing forcibly, swelling inside the thighs and knees, and dysfunction of the big toe. Improper diet and overwork injure the Spleen. Excess patterns manifest as dreams of joyous singing and happiness; deficiency patterns manifest as dreams of disputes over food. Overthinking injures the Spleen; Anger can overcome Thinking. Dampness injures the muscles; Wind can overcome Dampness. Sweet taste injures the muscles; Sour taste can overcome Sweet. Sweet flavor travels to the muscles; if muscles are diseased, avoid excessive consumption of sweet foods. Excessive consumption of sour flavors leads to thickening of muscle skin (calluses) and peeling of the lips.
The meridian pathway originates at the end of the big toe at Yinbai (SP1), receiving intersection from the Foot-Yangming Stomach Meridian. From there, it follows the medial side of the big toe along the border of white flesh at Dabu (SP2), passes behind the metatarsophalangeal joint (He Gu), and sequentially passes Taibai (SP3), Gongsun (SP4), and Shangqiu (SP5). It ascends to the anterior margin of the medial malleolus at Er Yinjiao (SP6), then ascends the medial aspect of the lower leg, following behind the tibia at Lougu (SP7), ascending two cun, emerging anterior to the Zhongdu (LR6) point of the Foot-Jueyin Liver Meridian, reaching Dijji (SP8) and Yinlingquan (SP9); from Yinlingquan (SP9), it ascends along the anterior margin of the medial knee bone, passing Xuehai (SP10) and Jimen (SP11), winding into the abdomen, passing Chongmen (SP12) and Fushhe (SP13), intersecting with Zhongji (CV3) and Guanyuan (CV4) of the Conception Vessel, then following Fujie (SP14) and Daheng (SP15), intersecting with Xiawan (CV10) of the Conception Vessel; passing Fu'ai (SP16), crossing the Riyue (GB24) of the Foot-Shaoyang Gallbladder Meridian and Qimen (LR14) of the Foot-Jueyin Liver Meridian, then following the interior of Fu'ai (SP16) of this meridian, descending to the area between Zhongwan (CV12) and Xiawan (CV10) of the Conception Vessel, connecting to the Spleen and linking to the Stomach. From Fu'ai (SP16), it ascends through the diaphragm, following Shidou (SP17), Tianxi (SP18), Xiongxiang (SP19), and Zhourong (SP20); from Zhourong (SP20), it curves outward and downward to Dabao (SP21), then from Dabao (SP21) curves outward and upward, intersecting with Zhongfu (LU1) of the Lung Meridian, ascending to the interior of Renying (ST9) of the Stomach Meridian, flanking the pharynx, connecting to the root of the tongue, scattering at the base of the tongue, and terminating; its branch follows Fu'ai (SP16) to the stomach region, intersects outside Zhongwan (CV12) of the Conception Vessel, ascends through the diaphragm, pours into the interior of Tanzhong (CV17) of the Conception Vessel, and intersects with the Hand-Shaoyin Heart Meridian, continuing from the descent of the Ji Quan (HT1) point.
