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 而唇揭。
多食甘，则骨痛而发落。
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。

多吃咸味食物，会导致血脉凝滞不畅且面色改变。
多吃苦味食物，会导致皮肤干枯且毛发脱落。
多吃辛味食物，会导致筋脉拘急且指甲枯槁。
多吃酸味食物，会导致肌肉增厚起茧且口唇翻揭。
多吃甘味食物，会导致骨骼疼痛且头发脱落。
咸味入血分，患有血病的人不要多吃咸味食物。
苦味入骨分，患有骨病的人不要多吃苦味食物。
辛味入气分，患有气病的人不要多吃辛味食物。
酸味入筋分，患有筋病的人不要多吃酸味食物。
甘味入肉分，患有肉病的人不要多吃甘味食物。
各种五味进入胃中，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。长期食用会使该脏之气偏盛，这是事物变化的常规；但气偏盛日久，则是导致早夭的原因。
患有热中（内热炽盛）和消中（消渴重症）的病证，不可服用膏粱厚味、芳草类药物或石药。芳草类药物的气味芳香美好，石药的气味猛烈悍急，这两类药物的药性急疾坚劲，因此如果不是性情平和舒缓的人，不可以服用这些药物。体内的热气剽悍，药物的气性也是如此，两种气相遇，恐怕会内伤脾脏。脾脏属土，而厌恶木气。服用这类药物的人，到了甲乙日（木旺之日）需要重新讨论病情。
海藏（张元素，号海藏先生）说：汤液（煎剂）作为主要药物，最为恰当，其余方论中所记载的杂例，与汤液相比稍有不同，为什么呢？这是因为伊尹和张仲景取其治疗的特长。他们的特长，是神农所注重的。怎么知道呢？《本草》中说：一种药物主治十种疾病，是取其偏长的功效为本。另外应当取洁古（张元素，号洁古老人）《珍珠囊》中的断例作为准则，其中，药物所主治的功效，不必多言，只有一两句，多的也不过三四句。这不是为了追求简略，也是取其主治的特长，所以不写得多。

所以治病的人，必须明白六气化分的治理规律，五味五色所生的关系，五脏适宜的饮食，才可以谈论气血盈虚及疾病发生的头绪。谨慎地观察气候适宜的情况，不要错过疾病的机理。主治的药物取决于采药的年份。顺应岁运来储备药物，就不会遗漏主治的功效。为什么要用前一年的药物呢？因为那是天地精专之气，这种精专之气的药物肥厚浓郁，又在使用时，正值其纯正的气味。五运主岁，运气不足则物产薄弱，运气有余则物产精纯，如果不精专则气散，气散则物不纯。因此质地相同但等级不同，形状质地虽然相同，但效力作用却不同。这就是气味有浓薄，性用有躁静，治疗变化有多少，力化有浅深的道理。
表格一至表格九的内容略。
Excessive consumption of salty foods leads to coagulation and stagnation of the vessels (Mai, 脉) with changes in complexion.
Excessive consumption of bitter foods leads to dryness of the skin (Pi, 皮) and loss of hair (Mao, 毛).
Excessive consumption of pungent foods leads to tension of the sinews (Jin, 筋) and withered nails.
Excessive consumption of sour foods leads to calluses on the flesh (Rou, 肉) and peeling of the lips (Chun, 唇).
Excessive consumption of sweet foods leads to bone pain (Gu Tong, 骨痛) and hair loss.
Salty flavor enters the Blood (Xue, 血); those with Blood diseases should not consume excessive salty foods.
Bitter flavor enters the Bones (Gu, 骨); those with Bone diseases should not consume excessive bitter foods.
Pungent flavor enters the Qi (Qi, 气); those with Qi diseases should not consume excessive pungent foods.
Sour flavor enters the Sinews (Jin, 筋); those with Sinew diseases should not consume excessive sour foods.
Sweet flavor enters the Flesh (Rou, 肉); those with Flesh diseases should not consume excessive sweet foods.
When the Five Flavors enter the Stomach (Wei, 胃), each tends toward its preferred organ for treatment: Sour first enters the Liver (Gan, 肝), Bitter first enters the Heart (Xin, 心), Sweet first enters the Spleen (Pi, 脾), Pungent first enters the Lung (Fei, 肺), and Salty first enters the Kidney (Shen, 肾). Long-term consumption increases the Qi of that organ, which is the normal course of transformation; however, prolonged excess of Qi is the cause of premature death.
Patients with Re Zhong (Internal Heat, 热中) and Xiao Zhong (Severe Xiao Ke/Consumption Disease, 消中) should not consume rich fatty foods (Gao Liang, 膏粱), fragrant herbs (Fang Cao, 芳草), or mineral drugs (Shi Yao, 石药). The Qi of fragrant herbs is beautiful/aromatic, and the Qi of mineral drugs is fierce/han (Han, 悍). Both have urgent, firm, and strong properties; therefore, they should not be taken by individuals who do not have a calm and gentle disposition. Internal heat is swift and fierce, and drug Qi is similar; when these two Qi meet, there is fear of internal injury to the Spleen. The Spleen belongs to Earth (Tu, 土) and dislikes Wood (Mu, 木). Patients taking these drugs should have their condition re-evaluated on Jia-Yi days (Wood-dominant days).
Haizang (Zhang Yuansu, courtesy name Haizang) said: Tang Ye (Decoctions) are the most appropriate primary medicines. The miscellaneous examples recorded in other formula theories differ slightly from decoctions. Why? Because Yi Yin and Zhang Zhongjing utilized their specific therapeutic strengths. Their strengths align with what Shennong emphasized. How do we know this? The Ben Cao (Materia Medica) states: "One substance treats ten diseases," utilizing its specific strength as the basis. Furthermore, one should take the diagnostic rules from Jiegu's Zhen Zhu Nang (Pearl Pocket) as a standard. In it, the main indications of drugs need not be elaborated upon; usually only one or two sentences, at most three or four. This is not for the sake of brevity, but to highlight the specific strength of the drug's indication, hence the lack of extensive description.
Tables 1 through 9 are omitted.
Therefore, in treating diseases, one must understand the governance of the Six Transformations (Liu Hua, 六化), the generation of Five Flavors and Five Colors, and the dietary suitability for the Five Zang Organs, so that one may discuss the threads of Qi/Blood fullness/deficiency and the origin of disease. Carefully observe the appropriateness of Qi (climate/seasonal factors) and do not miss the disease mechanism. The choice of primary medicine depends on the year of harvest. Preparing substances according to the annual Qi ensures no main efficacy is missed. Why use previous year's substances? Because they possess the exclusive essence (Zhuan Jing, 专精) of Heaven and Earth. This exclusive Qi makes drugs plump and rich. When used, they possess their purest Qi. The Five Yun (Movements) govern the years; insufficient Yun results in thin/poor quality produce, while abundant Yun results in refined/pure produce. Without exclusivity, Qi scatters; scattered Qi means impure produce. Thus, although substances may be similar in quality, their grades differ. Although shape and substance are the same, their efficacy differs. This refers to the fact that flavors have richness or thinness, natures/actions have agitation or stillness, treatments have varying degrees of transformation, and powers have shallow or deep effects.
Tables 1 through 9 are omitted.
