一、医事本吾儒之余事，可以济物，患难中可以防身。古人云，养道而已。切不可恃意
妄为
穿凿，与人为治，误人生命，不惟祸及自身，殃堕九祖尔。但以活人之心为心，本于因民之
所利而利之，一则生意自有，二则祸患自无也。
一、吾宗累世簪缨名门右族，吾父橘泉翁始从丹溪朱彦修学此术，患难中实得济。余又
得从
乡先生冯庭干、许宗鲁、丘克容数君子印正，方始道明艺精。但以因虚名，多受权要捃摭。
后吾子孙，遇道行时，仍守儒业可也。
一、此集本求古人为治之法，如指诸掌，可以见法例之变无穷，病证之机不一，谆谆求
究，藏为家宝，切不可示人，传诸不道不义之士。
一、伤寒证候，宜熟读《伤寒论》、《明理论》、《百证 》及《吴蒙斋指掌图》。大
抵紧要，在表里虚实寒热二字。况一证有兼证，看于着紧处先之。如结胸，身热发黄俱见，脉沉
而实，宜陷胸合茵陈急下之，后看次第调之。是以不可执一，当看证例约之。
一、杂证，看形气实者，宜以刘、张大法治之。形气虚，脉虚，或老幼羸弱脱荣者，宜
以东垣之法治之，药亦不可太杂。是以丹溪云∶吾每治病，用东垣之药，效仲景处方，庶品味数
少，药力专精也。又云以某药治某病。以某药监某药，以某药为引经。此得人之心法也。
一、行医本是儒家学者的余事，可以用来救助万物，在患难之中可以保全自身。古人说，修养道义罢了。切不可依仗主观臆断妄自作为，穿凿附会，为人治病，误人性命，这不仅祸及自身，还会殃及九代祖先。只应以救活人的心为心，基于顺应百姓利益而使其得利，一方面自然会有生机，另一方面祸患自然就没有了。
一、我家世代是戴冠缨的名门望族，我的父亲橘泉翁开始跟随丹溪朱彦修学习这门医术，在患难中确实得到了救济。我又得以向乡里的前辈冯庭干、许宗鲁、丘克容几位君子请教指正，这才使道理明了、技艺精湛。但因为虚名，多受到权贵们的挑剔和攻击。后来我的子孙，如果遇到道术盛行、时机适宜的时候，仍应坚守儒业即可。
一、这部文集本意是探求古人治疗的方法，如同指着手掌一样清楚，可以看到法则例证的无穷变化，病证机理的不尽相同，恳切地要求深入探究，珍藏作为家宝，切不可展示给别人，传给那些不道德、不正义的人。
一、伤寒（外感热病）的证候，应该熟读《伤寒论》、《明理论》、《百证》以及《吴蒙斋指掌图》。大抵紧要之处，在于表里、虚实、寒热这八个字。况且一个证候有兼夹证候，要看顾到关键之处先处理。比如结胸（邪热与水饮互结于胸膈），身体发热、发黄都出现，脉象沉而实，适宜用陷胸汤合茵陈蒿汤急下之，之后再按次序调理。因此不可固执一端，应当根据证候条例来约束判断。
一、杂病，看形体气力充实的，适宜用刘完素、张从正的治疗方法。形体气力虚弱，脉象虚弱，或者是老幼瘦弱、气血脱失的，适宜用李东垣的治疗方法，药物也不可以太杂乱。所以丹溪说：我每次治病，使用东垣的药物，效法仲景的处方，大概品味数量少，药力专精吧。又说用某药治某病。用某药监制某药，用某药作为引经药。这是得到人心的秘法啊。
1. Medical practice is but a secondary pursuit for Confucian scholars; it can be used to benefit all things and protect oneself in times of hardship. The ancients said, "Cultivate the Dao." One must absolutely not act arbitrarily based on subjective assumptions or force interpretations. When treating others, causing death by error will not only bring disaster upon oneself but also curse nine generations of ancestors. One should take the heart of saving lives as one's own heart, acting in accordance with what benefits the people. In this way, vitality will naturally arise, and disasters will naturally cease.
2. My lineage has been a prominent family of officials for generations. My father, Mr. Juquan, first learned this art from Zhu Yanshou (Zhu Danxi). He truly benefited from it during times of hardship. I further sought correction from several gentlemen, elders of our township: Feng Tinggan, Xu Zonglu, and Qiu Kerong. Only then did my understanding of the principles become clear and my skills refined. However, due to my empty reputation, I suffered much criticism and harassment from powerful figures. For my descendants, if they encounter times when the Dao is practiced and opportunities are favorable, they may still adhere to their Confucian profession.
3. This collection seeks to explore the methods of treatment used by the ancients, making them as clear as pointing at one's palm. It allows one to see the infinite variations in therapeutic principles and the diverse mechanisms of disease manifestations. It earnestly urges deep investigation. Keep it as a family treasure. Do not show it to others, nor pass it to those who are unprincipled and unjust.
4. Regarding the syndromes of Shanghan (Cold Damage), one should familiarize oneself with *Shanghan Lun* (Treatise on Cold Damage), *Mingli Lun* (Treatise on Explaining Principles), *Baizheng* (Hundred Syndromes), and *Wu Mengzhai Zhizhang Tu* (Diagram of Finger and Palm by Wu Mengzhai). Generally, the crucial points lie in the concepts of Exterior/Interior (Biao-Li), Deficiency/Excess (Xu-Shi), and Cold/Heat (Han-Re). Moreover, a single syndrome may have concurrent syndromes; one must attend to the critical aspects first. For example, in Jie Xiong (Chest Binding), where body heat and jaundice appear simultaneously, and the pulse is deep and excess, one should urgently use Xiaoxiong Tang (Chest-Draining Decoction) combined with Yinchen Hao Tang (Artemisia Capillaris Decoction) to purge downward, followed by sequential regulation. Therefore, one must not adhere rigidly to a single approach but should constrain judgment according to the syndrome patterns.
5. For miscellaneous diseases, if the physical constitution and Qi are robust, treat using the methods of Liu Wansu and Zhang Congzheng. If the physical constitution and Qi are deficient, the pulse is weak, or the patient is an old person, child, emaciated individual, or suffering from depletion of Jing (Essence), treat using the methods of Li Dongyuan. The medications should not be too mixed. Thus, Danxi stated: "Whenever I treat diseases, I use medicines from Dongyuan [Li Dongyuan] and follow the prescription style of Zhongjing [Zhang Zhongjing], so that the number of ingredients is small, and the medicinal power is concentrated and specialized." He also said: Use a certain herb to treat a certain disease; use a certain herb to supervise another herb; use a certain herb as a guiding herb (Yin Jing Yao). This is the secret method that wins people's hearts.
