饮食不节和过度劳累属于内伤，或者因为饥饿、饱食以及房事过度所致。风寒邪气侵袭人体称为外感，只要辨别清楚并加以调理治疗，就不会有妨碍。人迎脉（左寸脉）紧甚且手背发热，寒热症状交替发作没有间歇；如果恶寒无汗且鼻塞不通，这就是外感病症，可以明确区分。内伤的病症表现为气口（右寸脉）洪大，手心发热且轻微怕风；寒热症状间歇性发作，不知食物味道，再加上气息虚弱、言语慵懒。内伤引起的恶寒通过保暖可以缓解，而外感引起的恶寒即使靠近火源寒冷感依然侵袭身体。外感和内伤同时存在的，需要仔细辨别脉象和症状。内伤属于不足之证，急需补益；外感属于有余之证，治法不同。或者先补养正气，或者先发散邪气，在先后顺序的选择上不能草率随意。使用益气汤加入生姜和大枣吞服，调和气血以散微寒；若救肾水亏虚，用酒炒黄柏；若入心养血，增加红花。若有自汗，去掉升麻和柴胡；若夜间失眠，加入姜炒酸枣仁。头痛使用川芎和蔓荆子，口渴干葛根最为灵验。头顶痛时使用藁本，怔忡惊悸使用枣仁、茯神（严重者加远志、柏子仁、石菖蒲等药味）。饮食积滞加麦芽、神曲、山楂来消食实积，腹泻添加泽泻、白芍和云苓。胸闷用黄连和枳实去除，有痰湿则加入半夏、茯苓作为主药。防己和木瓜治疗脚部软弱无力，龙骨和牡蛎治疗遗精。身热使用羌活、防风、川芎、白芷（兼有风寒头痛者加上这些），火热上升使用知母、黄柏、玄参。黄连和黄芩两味药清除内热，菊花和熟地黄治疗眼睛疼痛。
后天之本归属于脾胃，受纳和运化饮食以滋养营卫之气。养生的妙诀在于节制饮食，脾胃受伤会导致身体虚弱。胸腹部饱闷并伴有反酸，嗳气、厌恶进食、腹痛连绵。严重时出现发热和头疼，只是身体不痛，这与伤寒不同。左关脉平和而右关脉紧，香砂平胃散功效显著。川芎、枳实并配合藿香，用水和生姜煎服，服药期间需忌口。消肉食用山楂，消果实用萝卜，消面食用莱菔子，消糯米食使用槟榔、神曲。饭食积滞用神曲兼麦芽，生冷之物用生姜、青皮、栝楼、草果来驱逐。鱼伤食用橄榄、花椒、紫苏，稻草可用于消化牛肉。麝香能消除蔬果积滞，葡萄、梅子、白蔻可解酒伤。挟带痰湿用半夏和生姜，挟带气滞用香附、砂仁、枳壳有益。挟带寒邪用苏梗、葛根、柴胡，吃了冷食则吃草豆蔻、肉桂、厚朴。伤饮（饮水过多或停滞）须配合四苓汤，呕吐时临服加入姜汁。茯苓、泽泻、白术治疗脾虚，泄泻用肉豆蔻、车前子、白术。食积郁久形成湿热，黄芩、黄连、大黄不可缺。再加入白术和泽泻，去掉藿香、砂仁和苍术。丹溪认为受到饮食寒邪，初起时温散和温利适宜。久了则成郁郁之热，热久生火就不能再用温法。宜用辛凉发表的方法，用辛寒之法调理中焦容易驱除邪气。轻症减少饮食，重症逐除积滞，东垣的妙论总不可忽视。
陈氏说：胃主受纳，饮食不下，是胃有病。脾主运化，饮食不消，是脾有病。
Dietary irregularity and overexertion constitute internal injury (Internal Injury), or result from hunger, excessive fullness, and sexual excess. Wind-cold pathogenic factors invading the human body are termed external contraction (External Contraction); once clearly differentiated and treated appropriately, no harm will ensue. A tight pulse at the Renying point (Left Cun position) accompanied by heat on the dorsal hand, with alternating chills and fever without interruption, indicates an external pathogen. Chills, absence of sweating, and nasal congestion distinguish this as an external contraction syndrome. In contrast, internal injury presents with a surging pulse at the Qikou point (Right Cun position), heat in the palms, slight aversion to wind, intermittent chills and fever, loss of taste, weak Qi, and lethargic speech. Chills due to internal injury resolve with warmth, whereas chills from external contraction persist even near fire. When external and internal conditions coexist, both pulse and symptoms must be carefully differentiated. Internal injury is a deficiency pattern requiring urgent tonification; external contraction is an excess pattern with different treatment principles. One may either tonify first or disperse first; the sequence must not be chosen arbitrarily. Yi Qi Tang (Qi-Supplementing Decoction) taken with fresh ginger and jujube harmonizes Qi and disperses mild cold. To rescue Kidney Yin deficiency, use Phellodendri Cortex (Huangbai) stir-fried with wine; to nourish Heart Blood, add Carthami Flos (Honghua). If spontaneous sweating occurs, remove Cimicifugae Rhizoma (Shengma) and Bupleuri Radix (Chaihu); for insomnia at night, add Ziziphi Spinosomi Semen (Suanzaoren) stir-fried with ginger. For headache, use Ligustici Chuanxiong Rhizoma (Chuanxiong) and Viticis Fructus (Manjingzi); for thirst, Puerariae Radix (Gegen) is efficacious. For vertex headache, use Libanodanis Resina (Xben). For palpitations and fright, use Ziziphi Spinosomi Semen (Zaoren) and Poria (Fushen) (for severe cases, add Polygalae Radix (Yuanzhi), Platycladi Semen (Bairen), and Acori Tatarinowii Rhizoma (Changpu)). For food stagnation, add Malto (Maiqu), Crataegi Fructus (Shanzha), and Ziziphi Spinosomi Semen (Shishi - *Note: Text says 'Shishi' likely referring to specific digestion aid or typo for Shenqu/Maiya context, but literal translation used*); for diarrhea, add Alismatis Rhizoma (Zexie), Paeoniae Radix Alba (Baishao), and Poria (Yunling). For chest stuffiness, use Coptidis Rhizoma (Chuanlian) and Immature Bitter Orange (Zhishi); for phlegm, Pinelliae Rhizoma (Banxia) and Poria (Fufu) serve as chief herbs. For weakness in the legs, use Stephaniae Tetrandrae Rhizoma (Fangji) and Saposhnikoviae Radix (Mugua); for seminal emission, use Longgu and Muli. For body heat, use Notopterygii Rhizoma et Radix (Qianghuo), Saposhnikoviae Radix (Fangfeng), Ligustici Chuanxiong Rhizoma (Xiong), and Angelicae Dahuricae Radix (Zhi) (add if wind-cold headache is present); for rising fire, use Anemarrhenae Rhizoma (Zhimu), Phellodendri Cortex (Baiyuan), and Scrophulariae Radix (Yuanshen). Coptidis Rhizoma (Lian) and Scutellariae Radix (Qin) clear internal heat; Chrysanthemi Flos (Juhua) and Rehmanniae Radix Preparata (Shudi) treat eye pain.
The Spleen and Stomach are the foundation of acquired constitution (Acquired Foundation), receiving and transforming food to nourish Ying and Wei Qi. The secret of health lies in dietary moderation; damage to the Spleen and Stomach leads to physical weakness. Symptoms include chest and abdominal fullness, acid regurgitation, belching, aversion to food, and continuous abdominal pain. Severe cases may involve fever and headache, but unlike Taiyang disease (Shanghan), the body does not ache. A normal pulse at the Left Guan position and a tight pulse at the Right Guan position indicate that Xiang Sha Ping Wei San (Fragrant Sand Regulate the Stomach Powder) is effective. Use Ligustici Chuanxiong Rhizoma (Chuanxiong), Immature Bitter Orange (Zhishi), and Pogostemonis Herba (Huoxiang), decocted with water and fresh ginger; dietary restrictions apply during treatment. For digesting meat, use Crataegi Fructus (Shanzha); for fruits, Radish (Luobo); for flour products, Raphani Semen (Laifu); for sticky rice, Arecae Semen (Binglang) and Massae Fermentatae Medicamentosa (Shenqu). For rice stagnation, use Shenqu and Malto (Maiya); for raw/cold foods, use Fresh Ginger (Shengjiang), Citri Reticulatae Pericarpium (Qingpi), Trichosanthis Radix (Gualu), and Tsaoko Fructus (Guoguo). For fish injury, use Olive (Ganlan), Zanthoxyli Fructus (Jiaozhu), and Perillae Folium (Zisu); straw can help digest beef. Musk (Shexiang) can eliminate vegetable and fruit stagnation; grapes, plums, and Amomi Fructus (Baokou) resolve alcohol injury. If complicated by phlegm, use Pinelliae Rhizoma (Banxia) and Fresh Ginger (Shengjiang); if complicated by Qi stagnation, Cyperi Rhizoma (Xiangfu), Amomi Fructus (Sharen), and Aurantii Fructus Immaturus (Zhike) are beneficial. If complicated by cold, use Perillae Caulis (Sugeng), Puerariae Radix (Gegen), and Bupleuri Radix (Chai); after eating cold food, consume Tsaoko Fructus (Caokou), Cinnamomi Ramulus (Guizhi), and Magnoliae Officinalis Cortex (Houpo). For fluid retention (Shang Yin), combine with Si Ling Tang (Four-Poria Decoction); add fresh ginger juice when administering for vomiting. Poria (Fuling), Alismatis Rhizoma (Zexie), and Atractylodis Macrocephalae Rhizoma (Baizhu) treat Spleen deficiency; for diarrhea, use Myristicae Semen (Roukou), Plantaginis Semen (Cheqianzi), and Atractylodis Macrocephalae Rhizoma (Baizhu). Food stagnation lingering long transforms into damp-heat; Scutellariae Radix (Qin), Coptidis Rhizoma (Lian), and Rheum Palmatum Radix et Rhizoma (Dahuang) are indispensable. Add Baizhu and Zexie, while removing Huoxiang, Sharen, and Atractylodis Rhizoma (Cangzhu). Danxi stated that initial exposure to dietary cold requires warm dispersion and warm purgation. Over time, it becomes stagnant heat; prolonged heat generates fire, making warm methods contraindicated. One should use acrid-cool releasing methods; acrid-cold regulation of the Middle Jiao easily dispels pathogens. Mild cases require reducing food intake; severe cases require eliminating stagnation. Dongyuan's profound theories should never be neglected.
Mr. Chen said: The Stomach governs reception; if food cannot go down, the Stomach is diseased. The Spleen governs transformation; if food is not digested, the Spleen is diseased.
