（足太阴脾经属于脏）
脾属土。中央对应黄色。是后天之本的木气所生（注：此处原文“后天之木也”疑为笔误或特定语境，通常脾为后天之本，属土，受命门火蒸化，此处依原文直译并保留术语）。下受命门之火，以蒸化谷食；上输布谷食之精微液汁，以灌溉脏腑。因此，人生存活命的根本，唯独脾土的功效最为巨大。然而脾的特性喜燥而恶湿，一旦受到湿邪浸渍，则脾土之力衰弱，肝木便会趁机克制并侮辱它（木乘土）。脾位于中焦，眼睑、鼻准及四肢都是其分野所属的部位。脾与胃互为表里，所以治疗脾病的用药大致相同。脾病没有表证，都属于里证。
脾虚的患者，右关脉必然细软。其症状表现为呕吐、泄泻、久痢、腹痛、肢体软弱、面色发黄、浮肿、肌肉消瘦、鼓胀、恶寒、自汗、气喘、积滞不消、饮食停滞化为痰饮、脱肛、肠血。

脾实证的病人，右关脉必然洪大有力。其症状表现为气积、血积、食积、痞积、虫积、痰饮、蛊胀、腹痛、不能进食。
气积者，是气郁结导致胸闷。用沉香降气丸主治。血积者，是蓄血作痛如针刺，有固定部位。用泽兰汤主治。食积者，是坚硬滞涩胀满。用大和中饮主治。痞积者，是血滞形成痞块，瘕癖可以摸到。用太无神功散、和中丸主治。虫积者，是湿热所化生。唇内有白点。用化虫丸主治。痰饮者，有时停聚在心下，潜伏在两胁下有声音，咳嗽时疼痛。用小半夏加茯苓汤主治。蛊胀者，中焦充实有物，不是蛊毒就是瘀血。用和中丸主治。腹痛者，中有滞塞。用香砂二陈汤加山楂、麦芽、厚朴主治。不能进食者，是食物未消化。用保和丸主治。
脾寒的症状，右关脉必然沉迟，嘴唇和舌头必然发白。其症状表现为呕吐、泄泻、白痢、腹痛、身痛、黄疸、湿肿、肢冷、厥脱。
呕吐者，是食物不消化而反胃。用平胃散主治。泄泻者，是脾失职守。用六君子汤加炮姜主治。白痢者，是积寒损伤正气。用六君子汤加木香主治。腹痛者，疼痛绵绵不断。用香砂理中汤主治。如果夹杂食积且拒按，用木香丸。身痛者，拘急为风邪，沉重坠胀为湿邪。风邪用香苏散，湿邪用苍白二陈汤。黄疸者，是被湿邪制约，有阴寒之象，熏黄色黯。用茵陈五苓散主治。湿肿者，不烦渴，喜热饮。用五苓散主治。肢冷者，是阳气不能营卫于四肢末端。用附子理中汤主治。厥脱者，是气衰火熄。用附子理中汤加大剂量人参主治。
脾热的症状，右关脉必然数，舌苔薄而黄，嘴唇赤红。其症状表现为热吐、流涎、洞泄、泻渤（水样便）、赤痢、腹痛、目胞肿痛、酒疸、眩晕、阳黄胆。
热吐者，是食物不得入胃。用橘皮竹茹汤加姜汁炒黄连主治。流涎者，睡觉时流出口水沫，是脾热蒸腾湿气。用黄芩芍药汤主治。洞泄者，是暑湿胜过脾土，一泻如水注。用四苓散加益元散主治。泻渤者，是暑湿内搏，利下像蟹渤一样稀薄，将要变成痢疾。用黄芩芍药汤主治。赤痢者，是暑热伤及血分。用治痢奇方主治。或者用葛根治痢散。如果噤口不食，用开噤散。腹痛者，疼痛乍作乍止。用芍药甘草汤加黄连清解。目胞肿痛者，是火气上升。用柴芩煎主治。酒疸者，是酒湿积聚而成黄疸。用加味枳术汤加茵陈、葛根主治。眩晕者，是酒湿生热向上蒸腾。用葛花清脾汤主治。阳黄胆者，黄色像橘子皮且有光泽，眼睛和小便都黄。用栀子柏皮汤主治。如果大便闭塞，用茵陈大黄汤。
(Foot-Taiyin belongs to the Zang organs)
Spleen belongs to Earth. The center corresponds to yellow. It is the Wood of the Post-Heaven (Note: Textual ambiguity, literally "Post-Heaven Wood"). Below, it receives the fire of the Gate of Life (Mingmen) to steam and transform grain and food; above, it transports the fluids of grain and food to irrigate the Zang-Fu organs. Therefore, the root of life and survival for humans lies primarily in the great merit of Spleen Earth. However, its nature prefers dryness and dislikes dampness. Once soaked by dampness, the power of Earth weakens, and Liver Wood will take the opportunity to overcome and insult it (Wood overcoming Earth). Located in the Middle Jiao, the eyelids, the tip of the nose, and the four limbs are all its domains. It forms an interior-exterior relationship with the Stomach, so its medicinal prescriptions are roughly similar. Spleen diseases have no exterior syndromes; all belong to the interior.
For patients with Spleen Deficiency, the pulse at the Right Guan position must be fine and soft. Their symptoms include vomiting, diarrhea, chronic dysentery, abdominal pain, limb weakness, sallow complexion, edema, emaciation, distension (Gu Zhang), aversion to cold, spontaneous sweating, asthma, stagnation not resolving, dietary retention transforming into phlegm-damp, rectal prolapse, and intestinal bleeding.
Vomiting is due to emptiness in the middle. It is treated with Liu Jun Zi Tang (Six Gentlemen Decoction) plus Wei Jiang (Baked Ginger). Diarrhea is due to Earth failing to overcome dampness. It is treated with Wu Wei Yi Gong San (Five Ingredients to Enrich the Work Powder) plus Mu Xiang (Aucklandiae Radix). Chronic dysentery is due to Qi deficiency sinking downward. It is treated with Bu Zhong Yi Qi Tang (Tonify the Middle and Augment the Qi Decoction). Abdominal pain is due to Liver Wood overacting on Spleen Earth. It is treated with Shao Yao Gan Cao Tang (Peony and Licorice Decoction) plus Mu Xiang. Limb weakness is because Spleen governs the four limbs. It is treated with Wu Wei Yi Gong San (Five Ingredients to Enrich the Work Powder). A sallow complexion is the deficiency manifestation of the true color. It is treated with Liu Jun Zi Tang (Six Gentlemen Decoction). Edema, characterized by shiny skin that pits upon pressure, is treated with Bu Zhong Yi Qi Tang (Tonify the Middle and Augment the Qi Decoction) without Sheng Ma (Cimicifugae Rhizoma) and Chai Hu (Bupleuri Radix). Emaciation is because Spleen governs muscles. It is treated with Shi Quan Da Bu Tang (Comprehensive Great Tonifying Decoction). Distension (Gu Zhang), where the abdomen feels empty but is distended, is due to Qi deficiency. It is treated with Liu Jun Zi Tang (Six Gentlemen Decoction). Aversion to cold is due to Yang deficiency failing to reach the exterior. It is treated with Fu Zi Li Zhong Tang (Aconite Regulate the Middle Decoction). Spontaneous sweating is because Spleen governs muscles, and exterior deficiency fails to secure. It is treated with Wu Wei Yi Gong San (Five Ingredients to Enrich the Work Powder) plus Huang Qi (Astragali Radix) and Wu Wei Zi (Schisandrae Fructus). Asthma is due to Earth failing to generate Metal (Spleen deficiency failing to nourish Lung). It is treated with Wu Wei Yi Gong San (Five Ingredients to Enrich the Work Powder) plus Bei Wu Wei Zi (Schisandrae Fructus) and Niu Xi (Achyranthis Bidentatae Radix). Stagnation not resolving is due to insufficient power to transform grain. It is treated with Liu Jun Zi Tang (Six Gentlemen Decoction) plus Gu Ya (Setariae Germinatus) and Sha Ren (Amomi Fructus Rotundus) plus Rou Gui (Cinnamomi Cortex). Dietary retention transforming into phlegm-damp is due to Earth failing to overcome dampness. It is treated with Liu Jun Zi Tang (Six Gentlemen Decoction). Rectal prolapse is due to Qi deficiency sinking downward. It is treated with Bu Zhong Yi Qi Tang (Tonify the Middle and Augment the Qi Decoction). Intestinal bleeding is due to Spleen failing to control blood. It is treated with Gui Shao Liu Jun Zi Tang (Angelica Sinensis and Peony Six Gentlemen Decoction).
For Spleen Excess patterns, the pulse at the Right Guan position must be surging and solid. Symptoms include Qi accumulation, Blood accumulation, Food accumulation, Pi accumulation (mass), Worm accumulation, Phlegm-fluid retention, Gu distension, abdominal pain, and inability to eat.
Qi accumulation is Qi stagnation causing chest oppression. It is treated with Chen Xiang Jiang Qi Wan (Aquilaria Descending Qi Pill). Blood accumulation involves stasis causing stabbing pain with a fixed location. It is treated with Ze Lan Tang (Lycopus Decoction). Food accumulation involves hardness, stagnation, and fullness. It is treated with Da He Zhong Yin (Great Harmonize the Middle Infusion). Pi accumulation involves blood stasis forming masses, such as Jia and Pi masses that can be palpated. It is treated with Tai Wu Shen Gong San (Tai Wu Divine Power Powder) and He Zhong Wan (Harmonize the Middle Pill). Worm accumulation is transformed from damp-heat, indicated by white spots inside the lips. It is treated with Hua Chong Wan (Expel Worms Pill). Phlegm-fluid retention may stay under the heart or hide in the hypochondrium with audible sounds, causing pain when coughing. It is treated with Xiao Ban Xia Jia Fu Ling Tang (Minor Pinellia plus Poria Decoction). Gu distension involves solidity in the middle, which is either Gu pathogen or blood stasis. It is treated with He Zhong Wan (Harmonize the Middle Pill). Abdominal pain is due to internal stagnation. It is treated with Xiang Sha Er Chen Tang (Costus and Amomum Two Old Decoction) plus Shan Zha (Crataegi Fructus), Mai Ya (Hordei Fructus Germinatus), and Hou Po (Magnoliae Officinalis Cortex). Inability to eat is due to undigested food. It is treated with Bao He Wan (Preserve Harmony Pill).
Symptoms of Spleen Cold involve a Right Guan pulse that is deep and slow, and white lips and tongue. Symptoms include vomiting, diarrhea, white dysentery, abdominal pain, body pain, jaundice, damp swelling, cold limbs, and Jue collapse.
Vomiting is food indigestion leading to regurgitation. It is treated with Ping Wei San (Calm the Stomach Powder). Diarrhea is Spleen failing in its duty. It is treated with Liu Jun Zi Tang (Six Gentlemen Decoction) plus Pao Jiang (Prepared Ginger). White dysentery is accumulated cold damaging Qi. It is treated with Liu Jun Zi Tang (Six Gentlemen Decoction) plus Mu Xiang (Aucklandiae Radix). Abdominal pain is continuous and unceasing. It is treated with Xiang Sha Li Zhong Tang (Costus and Amomum Regulate the Middle Decoction). If accompanied by food retention and tenderness upon pressure, use Mu Xiang Wan (Aucklandiae Pill). Body pain: cramping is Wind, heaviness is Damp. For Wind, use Xiang Su San (Aquilaria and Perilla Powder); for Damp, use Cang Bai Er Chen Tang (Atractylodes Macrocephala and Chinensis Two Old Decoction). Jaundice is Earth constrained by Damp, showing Yin-Cold signs, with dark yellow hue. It is treated with Yin Chen Wu Ling San (Artemisiae Scopariae Five Ling Powder). Damp swelling involves no thirst, preference for heat. It is treated with Wu Ling San (Five Ling Powder). Cold limbs are due to Yang Qi failing to nourish the four extremities. It is treated with Fu Zi Li Zhong Tang (Aconite Regulate the Middle Decoction). Jue collapse is due to Qi decline and Fire extinguishing. It is treated with Fu Zi Li Zhong Tang (Aconite Regulate the Middle Decoction) with a large dose of Ren Shen (Ginseng Radix).
Symptoms of Spleen Heat involve a Right Guan pulse that is rapid, thin yellow tongue coating, and red lips. Symptoms include hot vomiting, salivation, severe diarrhea, watery stool, red dysentery, abdominal pain, swollen and painful eyelids, Wine Jaundice, vertigo, and Yang Jaundice.
Hot vomiting is food unable to enter the stomach. It is treated with Ju Pi Zhu Ru Tang (Tangerine Peel and Bamboo Shaving Decoction) plus Jiang Zhi Chao Huang Lian (Ginger Juice-fried Coptidis Rhizoma). Salivation is drooling during sleep, caused by Spleen Heat steaming Dampness. It is treated with Huang Qin Shao Yao Tang (Scutellaria and Peony Decoction). Severe diarrhea is Summerheat-Damp overpowering Earth, flowing like a torrent. It is treated with Si Ling San (Four Ling Powder) plus Yi Yuan San (Benefit Primordial Powder). Watery stool is Summerheat-Damp clashing internally, resembling crab roe discharge, likely to become dysentery. It is treated with Huang Qin Shao Yao Tang (Scutellaria and Peony Decoction). Red dysentery is Summerheat-Heat damaging Blood. It is treated with Zhi Li Qi Fang (Miraculous Formula for Dysentery) or Ge Gen Zhi Li San (Kudzu Root Dysentery-Resolving Powder). If mouth is closed (anorexia), use Kai Jin San (Open the Mouth Powder). Abdominal pain comes and goes intermittently. It is treated with Shao Yao Gan Cao Tang (Peony and Licorice Decoction) plus Huang Lian (Coptidis Rhizoma) to clear heat. Swollen and painful eyelids are due to Fire rising. It is treated with Chai Qin Jian (Bupleurum and Scutellaria Decoction). Wine Jaundice is Jaundice formed by accumulation of Wine-Damp. It is treated with Jia Wei Zhi Zhu Tang (Modified Immature Bitter Orange and Atractylodes Macrocephala Decoction) plus Yin Chen (Artemisiae Scopariae Herba) and Ge Gen (Puerariae Lobatae Radix). Vertigo is due to Heat steaming upward from Wine-Damp. It is treated with Ge Hua Qing Pi Tang (Kudzu Flower Clear Spleen Decoction). Yang Jaundice presents with bright orange-yellow skin luster, yellow eyes and urine. It is treated with Zhi Zi Bai Pi Tang (Gardeniae and Phellodendri Bark Decoction).
