古今医家谈论方剂的很多，其失误在于多的时候杂乱而不精，少的时候则遗漏而不全，读者难免有遗恨。我在闲暇之日纵观群书，搜集预防养生的良好方法和已验证的名方，参酌自己的见解，区分四季南北的差异，权衡轻重缓急的适宜性，另编为两册，命名为《养生类要》，交给刻工传布四方。或许疾病将要发作时，能在未成形之前进行预防；或者疾病突然产生时，寻找医生不遇，依照此法行事，未必没有帮助。如果说其中的道理就在这里，我吴正伦岂敢当此赞誉？谨此告知。

Physicians of ancient and modern times have discussed prescriptions in great numbers. Their errors lie in that when numerous, they are miscellaneous and imprecise; when few, they are incomplete and omit details. Readers cannot help but feel regret. In my leisure time, I have perused various books, collected excellent methods for preventive care and verified famous prescriptions, incorporated my own insights, distinguished differences between seasons and regions (North and South), and weighed the appropriateness of severity and urgency. I compiled them into two volumes named *Yangsheng Leyao* (Essentials of Health Preservation), entrusted them to printers for dissemination throughout the world. Perhaps when diseases are about to manifest, one can prevent them before they take shape; or if diseases arise suddenly and doctors are unavailable, following these methods may certainly provide some assistance. If one says the Dao lies herein, how dare I, Lun, claim such credit? I respectfully inform you.
