（里寒而停水 方见阳明虚证） 干呕旋惊口吐涎，时时头痛入于巅，胃停水饮寒尤盛，汤用吴萸病可痊。
（里寒而呕厥） 呕而脉弱病情危，小便适当复利时，身热虽微偏见厥，汤煎四逆尚堪医。
白头翁汤
（证附 阳回而里热） 厥阴泄利水频思，肝热旋惊下重时，连柏双清君相火，白头翁更合秦皮。
（阳回而里热 方见阳明实证） 下利阳回谵语生，肠中有粪燥难行，小承气用方真妙，胃热消除患自平。
（阳回而里热 方见太阳坏病） 利后阳回实病无，痞消心下按之濡，烦生终是因虚得，栀子煎汤效可图。

（里寒而停水，方见阳明虚证）干呕伴眩晕、口吐涎沫，头痛时常发作并直达头顶，因胃中停留水饮且寒气尤盛所致，服用吴茱萸汤即可痊愈。
（里寒而呕厥）呕吐且脉象微弱，病情危重，若小便能够适当恢复通畅，虽然身体有轻微发热但四肢却出现厥冷，煎服四逆汤尚可医治。
（证附 阳回而里热）厥阴病泄利，患者频繁思饮冷水，肝经有热导致眩晕及肛门下坠感时，黄连、黄柏双清君火与相火，白头翁汤再合秦皮使用。
（阳回而里热，方见阳明实证）下利后阳气回复却产生谵语，肠中有燥屎难以排出，此时使用小承气汤方为真妙，胃热消除后病患自然平复。
（阳回而里热，方见太阳坏病）下利后阳气回复，实邪已去，痞满消散，心下部按之柔软，烦闷的产生终究是因为虚损所致，服用栀子汤疗效可期。
我少年时只读儒家书籍，而不精通医术。恰逢家母患病，缠绵数年之久，省内名医，几乎遍请诊治，但病终未除。后来延请一位医生，用猛药攻伐，病情更加严重，岌岌可危。我因此思考，作为儿子却不知道医术，一旦遇到亲人患病，致使遭受庸医毒手，倘若因此长逝，那抱恨将如何呢？从此便毅然立志学医，但未经过名家指点，只是购买通行常见的几种医书阅读，涉猎十年，虽稍知大概，终究未得此道的真谛。等到三十七岁，科举高中，随后进入部里当差，公余闲暇之时，便去书市购买医书，先得到《徐氏八种》、《陈修园十六种》，继而又得到高士宗的《医学真传》，张隐庵的《侣山堂类辨》，后又得到《黄氏八种》，见各位先生的著作都远宗轩辕黄帝和岐伯，近法张仲景，始知《内经》、《伤寒论》、《金匮要略》各书，乃是万世医学之祖。得到这些书后，又研究二十年之久，朝夕揣摩，颇有心得。于是博采各书中纯粹精粹的部分，合辑为一编，命名为《医学摘粹》，意思是美善兼得，即可措施得当。书成之后，我便出任凉州知府，在甘肃滞留十六年，而医书并未离手。等到民国改元，我便由西宁大臣职位卸任回乡。同乡劝我行医以济世救人，我欣然首肯。然而市井医生见我开出的方子，群起嘲笑并非议，说执守古方不能治今病。我听后说道，如果古方不能治病，想必时方能治病吗？于是询问病患，有经市井医生诊治过的，便索取原方查阅，见有治气的方子，便将攻气药全用上；见有治血的方子，便将攻血药全用上，推而广之，无论治何病，每拟定一方，必用药十六味，或二十味，杂药滥投，并不讲究方法。尤其奇怪的是，治伤寒不知通经解表，而先施攻下之方；治温病不知泄卫滋营，而专用苦寒之药；治虚劳只讲滋阴，治中风惟知温补，立方种种支离破碎，所以治病不效，而病家才来求治于我。然而这帮人不知道自己是趋时而误，反而说别人泥古不化而迂腐，岂非甘愿陷入迷途而不知返回者哉！我见医道谬妄如此，眼底杀运宏开，生灵遭劫，而我年已七十有七矣。到了这个时候如果不设法挽救，更待何人？于是邀请志同道合者，将伤寒、杂病各证、各方俱编成歌诀，以便后学诵读吟咏。倘有心求道者，幼而学之，壮而行之，未始不可以挽回气数也，于是作记。

(Interior cold with fluid retention, see Yangming deficiency syndrome) Dry heaving accompanied by dizziness and salivation, frequent headaches reaching the vertex, caused by water-fluid retention in the stomach and severe cold; Wu Zhu Yu Tang (Evodia Decoction) can cure the disease.
(Interior cold with vomiting and cold extremities) Vomiting with a weak pulse indicates a critical condition. If urination appropriately returns to normal, although there is slight body heat but cold extremities are present, Si Ni Tang (Frigid Extremities Decoction) can still be used for treatment.
Bai Tou Weng Tang (Pulsatilla Decoction)
(Case attachment: Yang recovery with interior heat) In Jueyin disease with diarrhea, if the patient frequently craves cold water, and experiences dizziness due to Liver heat along with tenesmus, Huang Lian (Coptidis Rhizoma) and Huang Bo (Phellodendri Cortex) clear both Ministerial Fire and Sovereign Fire; Bai Tou Weng Tang combined with Qin Pi (Amentotwigs Bark) should be used.
(Yang recovery with interior heat, see Yangming excess syndrome) After diarrhea, Yang recovers but delirium occurs; dry stool is difficult to pass in the intestines. Using Xiao Cheng Qi Tang (Minor Order the Qi Decoction) is truly excellent; once Stomach heat is eliminated, the illness naturally resolves.
(Yang recovery with interior heat, see Taiyang complicated disease) After diarrhea, Yang recovers, excess pathogens are gone, epigastric fullness dissipates, and the area below the heart feels soft upon palpation. The arising irritability is ultimately due to deficiency; Zhi Zi Tang (Gardenia Decoction) promises effective results.
In my youth, I only studied Confucian classics and was not proficient in medicine. When my mother fell ill, it lingered for years. Famous doctors throughout the province were consulted almost exhaustively, yet the illness remained. Later, a doctor was hired who used harsh purgatives, causing the condition to worsen dangerously. I reflected that as a son, not knowing medicine, if one encounters a relative's illness and suffers from quackery, leading to death, what would the regret be? Thus, I resolutely resolved to study medicine. Without guidance from renowned masters, I only purchased and read commonly circulated medical texts. After ten years of reading, although I knew the basics, I had not grasped the true essence of this path. At age thirty-seven, I passed the metropolitan examination and entered the ministry as a clerk. In my spare time, I went to book markets to buy medical books. First, I obtained *Xu Shi Ba Zhong* (Eight Works of Xu) and *Chen Xiuyuan Shi Liu Zhong* (Sixteen Works of Chen Xiuyuan). Subsequently, I acquired Gao Shizong’s *Yi Xue Zhen Chuan* (True Transmission of Medicine), Zhang Yin’an’s *Lv Shan Tang Lei Bian* (Classifications from Lv Shan Hall), and later *Huang Shi Ba Zhong* (Eight Works of Huang). Seeing that these authors revered Huangdi and Qibo in antiquity and followed Zhang Zhongjing in recent times, I realized that *Nei Jing* (Inner Canon), *Shang Han Lun* (Treatise on Cold Damage), and *Jin Gui Yao Lue* (Essential Prescriptions of the Golden Cabinet) are the ancestors of medicine for all generations. After obtaining these books, I studied them for another twenty years, pondering day and night, and gained considerable insight. Therefore, I collected the purest elements from various books into one compilation, naming it *Yi Xue Zhai Cui* (Selected Essence of Medicine), implying that combining beauty and goodness allows for appropriate measures. After completing the book, I served as Prefect of Liangzhou, remaining in Gansu for sixteen years without putting down my medical books. When the Republic of China was founded, I resigned from my post in Xining and returned home. Fellow townspeople advised me to practice medicine to help the times, which I gladly accepted. However, city physicians laughed at and criticized my prescriptions, claiming that ancient formulas cannot treat modern diseases. I asked, if ancient formulas cannot treat diseases, do contemporary formulas succeed? I then examined cases treated by city physicians, requesting their original prescriptions. I saw that for qi disorders, they exclusively used qi-attacking herbs; for blood disorders, they exclusively used blood-attacking herbs. Generally, for any disease, they prescribed sixteen or twenty herbs indiscriminately, without regard for method. Strangely, in treating Shanghan (Cold Damage), they did not understand unblocking meridians and releasing the exterior, but instead applied purgatives first; in treating Wenbing (Warm Diseases), they did not understand venting the defensive level and nourishing the nutritive level, but exclusively used bitter-cold herbs; in treating Xu Lao (Consumptive Disease), they only discussed yin-nourishment; in treating Zhong Feng (Wind Stroke), they only knew warming-tonification. Their prescriptions were fragmented, so treatments failed, and patients came to seek my care. Yet these people, unaware that their trend-following errors caused harm, accused others of being pedantic for adhering to antiquity. Are they not willingly lost in confusion without returning? Seeing medicine deviate thus, with widespread calamity and suffering among living beings, and being seventy-seven years old myself, if I do not now devise a way to save them, whom else shall I wait for? Thus, I invited like-minded colleagues to compile songs and rhymes covering Shanghan, miscellaneous diseases, syndromes, and formulas, to facilitate learning for future generations. If those earnestly seeking the Dao learn in youth and practice in adulthood, perhaps we can reverse the decline. Hence, I record this.
