医道之传，其来尚矣。历代圣君哲辅，靡不留心，自古仁人孝子，咸知注意。人生两间，身缘四大。风寒
暑湿侵蒸，喜怒忧思郁结，苦乐荣悴悉损精神，饥饱逸劳俱伤气血，有生难免，具体皆然，禀受虚实不同，必
有恒心乃济。（非唯医者贵有恒心，虽病者服药及起居饮食，亦必有恒，乃能康济一身） 草木良毒各异，未达
其性勿尝。药无不效，用当极灵，试嚼乌梅，遽齿酸而津溢；才吹皂角，立鼻嚏以气通。啖辣芥则泪垂，啮
花椒而气闭；阴胶知内疸所在，（阴胶，即甑中气垢。点少许于口中，即知脏腑所起。直达至住处，知痛足可医也）
硝末救脑痛欲亡。（硝石末吹鼻中，头痛立止） 囊皴漩多，夜煎萆 ；体寒腹大，全赖鸬 ；龟尿解噤，鼠
骨生牙；磁石引针，琥珀拾芥；鸾胶续剑，獭胆分杯；血投藕而不凝，漆得蟹而自散；葱液可以熬桂作水，
蟾膏乃能软玉如泥。略举数端证验，以明一切殊功。每用单行，则气纯而愈速，或时兼使，乃味杂而效迟。
唯相须佐使配合，则并力以收功；若相反畏恶交参，必争仇而播毒。疾之剧差，休戚所关；方之臧否，安危是
系，必合精详有据，岂宜火裂无稽？对症求药，须裒众善之长；随宜用药，庶获万全之效。

医道的传承，由来已久。历代圣明的君主和贤能的辅臣，无不悉心关注；自古以来的仁人孝子，也都深知重视。人生活在天地之间，身体由地、水、火、风“四大”元素构成。风寒暑湿等外邪的侵袭蒸灼，喜怒忧思等情志的郁结阻滞，无论是苦乐还是荣辱憔悴，都会损伤精神；无论是饥饱还是安逸劳累，都会伤害气血。这是生命过程中难免的现象，具体到每个人都是如此，只是由于禀赋有虚有实，所以必须有恒心才能治愈。（不仅仅是医生贵在要有恒心，即使是病人服药以及起居饮食，也必须有恒常规律，才能使全身康复）。草木药材的良性和毒性各不相同，如果不了解其药性就不要尝试服用。药物没有不生效的，关键在于使用得当极其灵验。试着咀嚼乌梅，立刻牙齿发酸且唾液涌出；刚吹入皂角末，立刻鼻子打喷嚏而气息通畅。吃辛辣芥菜则流泪，咬花椒则气机闭塞；阴胶能知道体内黄疸的位置（阴胶，就是蒸笼中的气垢。在口中点少许，就能知道脏腑病变的起源。直达病灶所在，知道疼痛之处即可治疗），硝石末吹入鼻中可救脑部剧烈疼痛欲死之症（硝石末吹入鼻中，头痛立即停止）。皮肤皴裂、小便浑浊多泡沫，夜晚煎煮萆薢；身体寒冷腹部胀大，完全依赖鸬鹚（此处指鸬鹚油或相关疗法，原文语境为特定偏方，保留原名）；龟尿能解除牙关紧闭，鼠骨能促进牙齿生长；磁石能引导针具（用于针灸定位或吸附），琥珀能吸附芥菜籽；鸾胶能接续断剑，獭胆能分开酒杯（比喻药效神奇）；血液滴入藕汁中不再凝固，生漆遇到螃蟹就会自行消散；葱液可以用来熬制桂枝成为水性制剂，蟾酥膏能使玉石变软如泥。略举这几端验证事例，以说明各种殊异的功效。每次单独使用一味药，则药气纯正而痊愈迅速；有时兼用多种药，则味道杂乱而疗效迟缓。只有相互需要、辅助佐使配合得当，才能合力收效；如果相反相畏相恶的药物交叉参杂，必定互相争斗仇视而播散毒害。疾病的严重与好转，关系到人的休戚与共；方剂的优劣，系于生命的安危，必须结合精细详细且有依据，怎么能像火烧裂纹那样无稽之谈呢？针对症状求取药物，必须汇聚众人的优点；根据适宜情况用药，才能获得万全的效果。

The transmission of the medical arts has existed since ancient times. Sages and wise ministers of successive dynasties have paid close attention to it, and benevolent people and filial sons since antiquity have all known to value it. Humans live between Heaven and Earth, and their bodies are composed of the "Four Elements" (Earth, Water, Fire, Wind). Invasion and steaming by external pathogens such as Wind, Cold, Summer-heat, and Dampness; stagnation and knotting caused by emotional fluctuations such as Joy, Anger, Worry, and Thought; whether experiencing suffering or joy, prosperity or decline—all damage the Spirit (Shen); whether experiencing hunger or fullness, idleness or labor—all injure Qi and Blood. This is inevitable in life, and applies to every individual; however, due to differences in innate constitution (Xu and Shi), one must possess perseverance to achieve healing. (It is not only doctors who need perseverance; patients must also maintain constancy in taking medicine, daily routine, and diet to restore health.)
Herbs vary in their beneficial and toxic properties; do not taste them if you do not understand their nature. There are no ineffective medicines, provided they are used with extreme efficacy. For example, chewing Sour Plum (Wumei) immediately causes tooth sourness and saliva overflow; blowing Soap Bean (Zaojiao) powder into the nose immediately induces sneezing and clears the airway. Eating spicy Mustard seeds causes tears to flow, while biting Sichuan Pepper (Huajiao) obstructs Qi flow. Yin Jiao (Mineral scale from steamers) can locate internal Jaundice (Danzhuang); blowing Nux Vomica/Stone Powder (Xiaoshi) into the nose saves severe headache approaching death. Cracked skin and turbid urine with many bubbles are treated at night with Decoction of Dioscorea Hypoglauca Rhizome (Bixie); a cold body and distended abdomen rely entirely on Cormorant oil (Luchi); Turtle urine resolves Trismus (Jin), and Rat bone promotes tooth growth; Magnetite (Cishi) guides needles, and Amber (Hupo) attracts mustard seeds; Luan Glue reconnects broken swords, and Marten Gall separates cups; Blood thrown into Lotus Root juice does not coagulate, and Lacquer dissolves upon contact with Crab; Scallion juice can be used to decoct Cinnamon Twig (Guizhi) into a water-like form, and Toad Venom paste (Changao) can soften jade like mud. These few examples demonstrate various extraordinary efficacies. When using single herbs alone, the Qi is pure and healing is rapid; when combining multiple herbs, flavors are mixed and effects are slower. Only through proper coordination of Mutual Enhancement (Xiangxu) and Assistant/Envoy (Zuoshi) combinations can efforts be concentrated to achieve success; if Contrary (Xiangfan), Incompatible (Xiangwei), or Hostile (Xiange) herbs are mixed, they will contend like enemies and disseminate toxicity. The severity or improvement of disease concerns our well-being; the merit or demerit of a formula determines life and death. Formulas must be precise, detailed, and evidence-based; how can they be baseless like cracks formed by fire? Seeking herbs for specific symptoms requires gathering the best qualities; applying medications according to appropriateness yields perfect results.
