药用燥热其候反阳者反从阳也其脉愈盛其症愈逆故云反也阴阳俱坏实谓难治医工不知其所以

观察那泰山为何曲折，是因为工匠们顺应自然；混沌的名山大川源头，依次形成湍急的溪流，盘旋汇入大海。天地之间自有其运行的规律，即使是极具智慧的人也无法创造这种造化之功。医学探究这一门学问，道理贯通千圣，其中“小方脉”（儿科）乃是众多科室中出类拔萃、议论关键的一科。
凡是进行调理，首先要裁断适宜与否；学习医篇章节，首要考察那些艰难复杂的病症。谁知道救活人的功德？我敬畏医道，通晓如仙般的高深境界，阴阳昭然若揭，施行功业便有所收获。唉！得遇良师传授奥妙宗旨，却未能完全契合真谛；认识本性、领悟机枢，才算达到至妙的境界。前贤著书保护后学，推诚相待，已经阐述了渊源，必须穷究确实的道理。在晦暗的夜晚持灯照明，感叹探索之路漫长；在清晨捧着珍宝的光辉，勇敢地跳跃前行。良工与鉴，汉代医者辄剖疑难之事，目的目略陈述管见之由。共十八章，希望志同道合者阅读，岂敢妄加品评？并非涉及狂妄诬蔑，试详述浅陋之言，必定展开宏大的见解。举一隅再举三反，再次表示钦佩。
议论说：顺症与逆症有别，阴阳不均，症候相加，面色与脉象导致混乱。唯有惊风发作时，按脉察症来比较它。阳证、症候、脉象都得到“阳”，阳就是顺症；阴证、症候、脉象都得到“阴”，阴就是逆症。阳证出现阴脉，说明病势欲传变；阴证出现阳脉，病势则相反。例如急惊风，乃是阳痫，脉象浮数洪弦，属于阳中之阳；又有脉象沉缓，属于阳中有阴。慢惊风，乃是阴痫，脉象沉细迟弱，属于阴中之阴；又有脉象浮大，属于阴中有阳。所谓“逆症似顺”，是指阴证中夹杂阳气，助阳而不能苏醒，回阳而不能生还。其候偏于亏损，虽然阴中有阳，但那阳气并非真阳。脉象使人生疑，不可攻伐，需详细推理而知晓，察辨可否之后才停止。
议论说：小儿伤寒，只需察辨表里而治疗，不以阴阳症候究竟为务，这是因为无关乎前关后之脉。所谓“纯阳之孩”，综合而言，此说中的阴候指的是慢惊风。凡是幼儿吐泻疾病发作引发慢惊，其症候没有反常表现，这大多是由急惊风传来，已成阴痫。用药用寒凉，病势转入慢脾风，药用燥热，其症候反而呈现阳象，这是反从阳也。其脉象愈盛，其症候愈逆，所以称为“反”。阴阳俱坏，实在难以治疗。医生不知其中的原理，只见到抽搐，肆意退热截风，良久却不引动抽搐，只是闭眼聚痰，冥冥之中如同播撒。症候如此，用什么药理来解释？请试着比较一下。
Observing why Mount Tai is winding, it is because craftsmen follow nature; the sources of chaotic famous mountains and rivers form turbulent streams in sequence, swirling into the sea. There are natural laws within heaven and earth; even the most wise cannot create such transformative power. Medicine explores this discipline, where principles connect through a thousand sages. Among all specialties, "Xiaofangmai" (Pediatrics) stands out as the crucial topic of discussion.
Whenever conducting regulation, one must first judge what is appropriate; when studying medical chapters, one must initially examine difficult cases. Who knows the virtue of saving lives? I revere the medical way, understanding profound truths akin to immortals, with Yin and Yang clearly manifest, achieving success through practice. Alas! Receiving the master's profound teachings but failing to fully grasp the true essence; recognizing one's nature and comprehending the mechanism constitutes the utmost subtlety. Former scribes protected later learners with sincerity, having already described the origins, yet one must exhaustively seek the truth. Holding a lamp in the dark night, sighing at the long path of exploration; holding precious light in the morning, leaping forward bravely. Good physicians reflect upon themselves, like Han dynasty doctors dissecting difficult matters, merely stating their humble views. Eighteen chapters in total, hoping comrades will read them; how dare I comment? This is not madness or slander, but a detailed exposition of shallow words, surely expanding grand insights. From one corner, infer three others, expressing admiration again.
It is discussed that there is a distinction between favorable (Shun) and unfavorable (Ni) conditions; Yin and Yang are uneven, symptoms add up, and complexion and pulse become chaotic. Only during the onset of convulsive disorders (Jingfeng), by palpating the pulse and observing symptoms, can we compare them. If Yang syndrome, symptoms, and pulse all exhibit Yang characteristics, Yang indicates a favorable condition; if Yin syndrome, symptoms, and pulse all exhibit Yin characteristics, Yin indicates an unfavorable condition. When a Yang syndrome presents a Yin pulse, the disease tends to transmit; when a Yin syndrome presents a Yang pulse, the situation is reversed. For instance, acute convulsion (Ji Jingfeng) is a Yang epilepsy; a floating, rapid, full, and wiry pulse belongs to Yang within Yang, while a deep and slow pulse belongs to Yang containing Yin. Chronic convulsion (Man Jingfeng) is a Yin epilepsy; a deep, fine, slow, and weak pulse belongs to Yin within Yin, while a floating and large pulse belongs to Yin containing Yang. The so-called "unfavorable condition resembling favorable" refers to Yin containing Yang, where assisting Yang fails to restore consciousness, and restoring Yang fails to generate life. The condition is predominantly deficient; although Yin contains Yang, that Yang is not genuine. The pulse causes doubt, making attack inappropriate; one must reason carefully to understand, ceasing only after discerning what is feasible.
It is discussed that pediatric cold damage (Shanghan) should be treated by examining exterior and interior aspects, without insisting on finalizing Yin and Yang syndromes, because it relates not to the anterior and posterior pulses. The concept of "pure Yang child," generally speaking, refers to the Yin syndrome of chronic convulsion. Whenever infants suffer from vomiting and diarrhea leading to chronic convulsion, the symptoms show no reversal, mostly transmitted from acute convulsion, becoming Yin epilepsy. Using cold-cooling medicines drives the disease into slow spleen wind (Man Pi Feng); using dry-hot medicines results in symptoms reversing to Yang, meaning they follow Yang. The pulse becomes stronger, and the symptoms more adverse, hence termed "reversal." When both Yin and Yang are damaged, treatment is truly difficult. Physicians do not understand the cause; seeing only spasms, they recklessly apply heat-clearing and wind-stopping methods. After a long time, spasms cease, eyes close, phlegm accumulates, and the state becomes obscure like scattering seeds. With such symptoms, what pharmacological principle applies? Please attempt to compare.
