凡是人到了十岁，五脏的功能开始稳定，血气已经通畅。此时正气主要运行于下部，所以喜欢奔跑。二十岁时，血气开始旺盛，肌肉骨骼正在生长，这是人体气血最盛盛的阶段。但此时腠理开始变得疏松，容颜逐渐衰退，鬓角头发出现斑白，气血相比盛期有所减退，不再剧烈活动，所以喜欢静坐。五十岁时，肝气开始衰退，肝脏叶片变薄，胆汁分泌减少，眼睛视力变得模糊不清。六十岁时，心气开始衰退，情绪容易悲伤忧郁，血气懈怠懒惰，所以喜欢多卧睡。七十岁时，脾气开始衰退，皮肤肌肉干枯萎缩，饮食食量减少。八十岁时，肺气开始衰退，魄与魂开始离散，说话经常出错。九十岁时，肾气枯竭，根本萎弱枯败，经脉空虚，所以听力下降甚至失聪。到了百岁，五脏功能全部衰竭，神气不能守舍，魂魄都离去，只剩形骸独自存在而死亡。又有的人未能享尽天年，不到一百岁就去世了，这都是因为脏腑不坚固，肌肉不充实，屡次遭受风邪侵袭，导致气血不通，真气与邪气相互攻伐，根基与枝叶混乱，因此不能长寿而终。
凡是女子七岁时，肾气开始充盛，更换牙齿，头发生长。到十四岁（二七），天癸（促进生殖机能成熟的物质）到来，任脉通畅，冲脉旺盛，月经按时来潮，所以能够生育。
凡是男子八岁时，肾气充实，头发生长，更换牙齿。到十六岁（二八），肾气旺盛，天癸到来，精气满溢而泄出，阴阳交合，所以能够生育。到二十四岁（三八），肾气平均，筋骨强劲，智齿生长，身体发育达到顶峰。到三十二岁（四八），筋骨隆盛，肌肉满壮。到四十岁（四九），肾气衰退，头发开始脱落，牙齿干枯。到四十八岁（五八），上部阳气衰微，面部焦枯发黑，鬓角头发斑白。到五十六岁（六八），肝气衰退，筋脉运动不利，天癸枯竭，精气少，肾脏功能衰弱，形体极度疲惫，头发牙齿脱落。到六十四岁（七八），牙齿和头发进一步脱落。
至于制定处方治疗疾病，应当先诊断知晓病源，观察其盈虚状态，然后施行补泻手法。辨别土地气候的寒暑差异，观察男女体质的盛衰变化，深入明白草木石药性味的甘苦酸辛咸等特性，根据时令气候进行损益调整。对于风气湿痹之证，病邪在表里之间游走不定，居无定处，应当先用散剂以平复病情，其次再用丸剂。丸药能够驱逐风冷，破除积聚，消除各种坚硬症结，增进饮食，调和营卫。能够综合参合这些方法并加以运用的人，可以称为上工（高明的医生）。所以说“医者意也”（医生的诊疗依赖于意念与悟性）。大抵而言，用来保养生命的药物多以君药为主，用来调养性情的药物多以臣药为主，用来治疗疾病的药物多以使药为主。审慎地选用药物，就能百无一失。
治疗寒证用热性药物，治疗热证用寒性药物，饮食不消化用催吐或泻下药物，鬼疰蛊毒用解毒杀虫药物，痈肿疮瘤用专治疮疡的药物……（原文此处中断）
When a person reaches ten years of age, the functions of the five Zang organs (Five Viscera) begin to stabilize, and the flow of Xueqi (Blood and Qi) is already smooth. At this stage, Zhengqi (Upright Qi) operates primarily in the lower part of the body; therefore, they enjoy running. At twenty years of age, Xueqi begins to flourish, and muscles and bones are growing. This represents the peak period of human vitality. However, at this time, the Couli (interstitial spaces and pores) begin to become loose, the complexion gradually declines, and gray hair appears on the temples. Compared with the peak state, Xueqi has diminished, and vigorous activity ceases; thus, they prefer sitting. At fifty years of age, Liver Qi begins to decline, the liver lobes become thinner, bile secretion decreases, and vision becomes blurred. At sixty years of age, Heart Qi begins to decline, leading to frequent sadness and melancholy; Xueqi becomes sluggish and lazy, resulting in a preference for lying down. At seventy years of age, Spleen Qi begins to decline, causing the skin and flesh to wither and dry up, and food intake to decrease. At eighty years of age, Lung Qi begins to decline, the Po (Corporeal Soul) and Hun (Ethereal Soul) begin to scatter, and speech becomes erroneous. At ninety years of age, Kidney Qi dries up and exhausts, the root becomes withered and枯 (dry), and the meridians become empty, leading to deafness or loss of hearing. Upon reaching one hundred years of age, the functions of all five Zang organs fail completely, Shenqi (Spiritual Qi) cannot remain within, and both Hun and Po depart, leaving only the physical form to perish. Some individuals do not live out their natural lifespan and die before the age of one hundred. This is due to the lack of solidity in the Zang-Fu organs and the lack of firmness in the muscles. Frequent exposure to Wind pathogens leads to obstruction of Xueqi, where True Qi and Evil Qi attack each other, and the roots and branches become chaotic, resulting in premature death.
For women, at seven years of age, Kidney Qi becomes abundant, teeth are replaced, and hair grows. At fourteen years of age (two sevens), Tian Gui (the substance that promotes reproductive maturity) arrives, the Ren Mai (Conception Vessel) becomes unobstructed, and the Chong Mai (Penetrating Vessel) becomes flourishing. Menstruation occurs regularly, enabling reproduction.
For men, at eight years of age, Kidney Qi is solid, hair grows, and teeth are replaced. At sixteen years of age (two eights), Kidney Qi is abundant, Tian Gui arrives, Jing Qi (Essential Qi) overflows and is discharged, Yin and Yang harmonize, enabling reproduction. At twenty-four years of age (three eights), Kidney Qi is balanced, sinews and bones are strong, wisdom teeth grow, and physical development reaches its peak. At thirty-two years of age (four eights), sinews and bones are robust, and muscles are full and strong. At forty years of age (five eights), Kidney Qi declines, hair begins to fall out, and teeth become dry. At forty-eight years of age (six eights), Yang Qi in the upper body declines, the face becomes darkened and withered, and hair on the temples turns gray. At fifty-six years of age (seven eights), Liver Qi declines, sinews move poorly, Tian Gui is exhausted, Jing Qi is scant, Kidney function weakens, the body becomes extremely fatigued, and hair and teeth fall out. At sixty-four years of age (eight eights), teeth and hair further deteriorate.
Regarding the formulation of prescriptions to treat diseases, one must first diagnose and understand the source of the disease, observe its excess or deficiency states, and then apply tonifying or reducing methods. One must distinguish the climatic differences of cold and heat in different regions, observe the vitality changes between men and women, and deeply understand the sweet, bitter, sour, pungent, and salty properties of herbs and minerals. Adjustments should be made based on seasonal climates. For conditions involving Wind, Dampness, and Bi syndrome (painful obstruction), where pathogens migrate between the interior and exterior without fixed locations, powder preparations should be used first to pacify the condition, followed by pill preparations. Pills can expel Wind and Cold, break up accumulations, dissolve various hard masses, promote appetite, and harmonize Ying (Nutritive) and Wei (Defensive) Qi. Those who can integrate and apply these methods comprehensively can be called Shang Gong (Superior Physicians). Hence it is said, "The physician's art lies in intent." Generally speaking, medicines for nourishing life contain more Jun (Monarch) herbs; medicines for nurturing nature contain more Chen (Minister) herbs; and medicines for treating diseases contain more Shi (Envoy/Assistant) herbs. If selected judiciously, errors will be rare.
To treat Cold syndromes, use Hot-natured drugs; to treat Heat syndromes, use Cold-natured drugs; for indigestion, use emetic or purgative drugs; for Gui Zhu (Ghost Attachment) and Gu Du (Poisonous Toxins), use antitoxic drugs; for abscesses, sores, and tumors, use specific dermatological drugs...
