肝色青，宜食甘，糯米、牛肉、枣、葵皆甘。心色赤，宜食酸，小豆、犬肉、李、韭皆酸。
肺色白，宜食
苦，麦、羊肉、杏、薤皆苦。脾色黄，宜食咸，大豆、豕肉、栗、藿皆咸。肾色黑，宜食辛，
黄黍、鸡肉、桃、葱皆辛。
咸走血，血病毋多食咸。苦走骨，骨病毋多食苦。辛走气，气病毋多食辛。酸走筋，筋
病毋多食酸。甘走肉，肉病毋多食甘。
五味入胃，各归所喜攻。酸先入肝，苦先入心，甘先入脾，辛先入肺，咸先入肾。久而
增气，物化之常；气增而久，夭之由也。盖阴之所生，本在五味；阴之五官，伤在五味。故味
过于酸，肝气以津，脾气乃绝。味过于咸，大骨气劳，短肌肤黑，心气抑。味过于甘，心气喘满，
色黑，肾气不衡。味过于苦，脾气不濡，胃气乃浓。味过于辛，筋脉沮弛，精神乃央。（与殃同。）
是故谨和五味，骨正筋柔，气血以流，腠理以密，则长有天命矣。
多食咸，则脉凝泣而变色。多食苦，则皮槁而毛拔。多食辛，则筋急而爪枯。多食酸，则
肉胝胸而唇揭。多食甘，则骨痛发落。
枳壳、陈皮与半夏，茱萸、野狼毒及麻黄。六般之药宜陈久，入用之时仔细详。
本草明言十八反，逐一从头说与君。人参、芍药与沙参，细辛、玄参及紫参，苦参、丹参并
前药，一见藜芦便杀人。白芨、白蔹并半夏，栝蒌、贝母五般真，莫见乌头与乌喙，逢之一反疾
如神。大戟、芫花并海藻，甘遂以上反甘草。若还吐蛊用翻肠，寻常犯之都不好。蜜、腊莫与
葱相睹，石决明休见云母。藜芦莫使酒米侵，人若犯之都是苦。
肝脏的颜色属青，适宜食用甘味食物，如糯米、牛肉、大枣、冬葵菜都属于甘味。心脏的颜色属赤，适宜食用酸味食物，如小豆、犬肉、李子、韭菜都属于酸味。
肺脏的颜色属白，适宜食用苦味食物，如小麦、羊肉、杏子、薤白都属于苦味。脾脏的颜色属黄，适宜食用咸味食物，如大豆、猪肉、栗子、大豆叶都属于咸味。肾脏的颜色属黑，适宜食用辛味食物，如黄米、鸡肉、桃子、葱都属于辛味。
咸味入血分，患有血病时不要多吃咸味食物。苦味入骨分，患有骨病时不要多吃苦味食物。辛味入气分，患有气病时不要多吃辛味食物。酸味入筋分，患有筋病时不要多吃酸味食物。甘味入肉分，患有肉（肌肉）病时不要多吃甘味食物。
五味进入胃中，各自趋向于它所喜好的脏腑进行攻治。酸味先入肝，苦味先入心，甘味先入脾，辛味先入肺，咸味先入肾。长期食用会使相应脏腑之气偏盛，这是事物变化的常规规律；但如果气偏盛的状态持续久了，就是导致早夭的原因。大概阴精的化生，根本在于五味；但阴精所属的五脏，损伤也在于五味。所以，味道过于酸，会导致肝气过盛溢满，脾气就会衰竭。味道过于咸，会导致大骨受损劳伤，肌肉短缩枯槁，面色发黑，心气受抑。味道过于甘，会导致心气喘促胀满，面色发黑，肾气失去平衡。味道过于苦，会导致脾气不能濡润，胃气变得浓滞。味道过于辛，会导致筋脉松弛败坏，精神受到损害。（“央”与“殃”同义，意为灾祸、损害。）因此，谨慎地调和五味，使骨骼端正、筋脉柔和，气血流畅，腠理致密，就能享有完整的自然寿命了。
多吃咸味，则血脉凝涩而面色改变。多吃苦味，则皮肤干枯而毛发脱落。多吃辛味，则筋脉拘急而指甲枯槁。多吃酸味，则肌肉生出硬皮且嘴唇干裂揭起。多吃甘味，则骨头疼痛且头发脱落。
枳壳、陈皮与半夏，山茱萸、野狼毒以及麻黄。这六种药物宜陈放久用，在入药使用时需仔细详察。
《本草》明确记载了十八反，我逐一从头对你说明。人参、芍药与沙参，细辛、玄参及紫参，苦参、丹参与前面的这些药，一旦遇到藜芦就会致死。白芨、白蔹并半夏，栝楼、贝母这五种真品，千万不要见到乌头与乌喙，遇到它们就会产生剧烈的相反作用。大戟、芫花并海藻，甘遂等以上药物都反甘草。如果还用吐蛊法使用翻肠草，平时犯了这些禁忌都不好。蜂蜜、蜂蜡不要与葱相遇，石决明不要见云母。藜芦不要让酒和米去侵染，人若犯了这些禁忌都是痛苦不堪。
The liver corresponds to the color green and is suited for consuming sweet-flavored foods; glutinous rice, beef, jujube, and Malva verticillata (Okra) are all sweet. The heart corresponds to the color red and is suited for consuming sour-flavored foods; adzuki beans, dog meat, plums, and Chinese chives are all sour.
The lungs correspond to the color white and are suited for consuming bitter-flavored foods; wheat, mutton, apricots, and Allium macrostemon (Buckbean) are all bitter. The spleen corresponds to the color yellow and is suited for consuming salty-flavored foods; soybeans, pork, chestnuts, and soybean leaves are all salty. The kidneys correspond to the color black and are suited for consuming pungent-flavored foods; yellow millet, chicken, peaches, and scallions are all pungent.
Salty flavor enters the blood; in cases of blood diseases, one should not consume excessive salty food. Bitter flavor enters the bones; in cases of bone diseases, one should not consume excessive bitter food. Pungent flavor enters the qi; in cases of qi diseases, one should not consume excessive pungent food. Sour flavor enters the sinews; in cases of tendon/sinus diseases, one should not consume excessive sour food. Sweet flavor enters the flesh; in cases of muscle/flesh diseases, one should not consume excessive sweet food.
The five flavors enter the stomach and each tends toward its preferred organ to exert its effect. Sour flavor first enters the Liver; bitter flavor first enters the Heart; sweet flavor first enters the Spleen; pungent flavor first enters the Lungs; salty flavor first enters the Kidneys. Long-term consumption increases the qi of the respective organ, which is the normal law of transformation; however, if this excess of qi persists for a long time, it becomes the cause of premature death. Generally, the generation of Yin essence originates from the five flavors; yet, the injury to the five Zang organs associated with Yin also stems from the five flavors. Therefore, if the flavor is excessively sour, Liver Qi will become overflowing, and Spleen Qi will cease. If the flavor is excessively salty, the large bones will suffer labor/damage, muscles will shrink and darken, and Heart Qi will be depressed. If the flavor is excessively sweet, Heart Qi will become panting and full, the complexion will turn black, and Kidney Qi will become unbalanced. If the flavor is excessively bitter, Spleen Qi will fail to moisten, and Stomach Qi will become thick/stagnant. If the flavor is excessively pungent, sinews and vessels will become flaccid and ruined, and the spirit will be harmed ("Yang" is synonymous with "Ying," meaning disaster/harm). Thus, by carefully harmonizing the five flavors, the bones remain upright, sinews remain flexible, Qi and Blood flow smoothly, and the interstices (Couli) remain dense, thereby allowing one to enjoy their natural lifespan.
Excessive consumption of salty food causes blood vessels to coagulate and stagnate, leading to changes in complexion. Excessive consumption of bitter food causes skin to wither and hair to fall out. Excessive consumption of pungent food causes sinews to contract and nails to wither. Excessive consumption of sour food causes calluses on the flesh and peeling lips. Excessive consumption of sweet food causes bone pain and hair loss.
Aurantii Fructus Immaturus (Zhi Ke), Tangerine Peel (Chen Pi), and Pinellia Rhizome (Ban Xia); Cornus Officinalis Fruit (Zhuyu), Wild Manroot (Langdu), and Ephedra Herb (Mahuang). These six types of medicines are best used when aged and stored for a long time; one must examine them carefully when administering.
The Materia Medica clearly states the Eighteen Incompatibilities; I shall explain them to you one by one from the beginning. Ginseng Root (Renshen), Peony Root (Shaoyao), and Glehnia Root (Shashen); Asarum Root (Xixin), Scrophularia Root (Xuanshen), and Consolida Root (Zishen); Sophora Root (Kushen), Salvia Root (Danshen), and the aforementioned herbs, if they encounter Veratrum Rhizome (Lilu), they can cause death. Bletilla Tuber (Baiji), Ampelopsis Radix (Bailian), and Pinellia Rhizome (Ban Xia); Trichosanthes Fruit (Gualou), and Fritillaria Bulb (Beimu)—these five true substances, do not see Aconite Lateral Root (Wutou) or Aconite Car root (Wuhui); encountering them creates a rapid contrary reaction. Euphorbia Root (Daji), Genkwa Flower (Yuanhua), and Sargassum Thallus (Haizao); Kansui Root (Gansui) and others above all contradict Licorice Root (Gancao). If one still uses Intestine-Turning Grass (Fanchangcao) for vomiting poison, violating these rules generally yields bad results. Honey and beeswax should not meet with Scallion Stem (Congbai); Concha Haliotidis (Shijueming) should not see Mica (Yunmu). Veratrum Rhizome (Lilu) should not be invaded by wine and rice; if humans violate these, the suffering is great.
