Predecessors stated that there are ten types of illnesses considered "incurable." If a patient can engage in self-reflection, even those deemed incurable may still be treatable.
(The ten incurable conditions include:) Indulgence in lust and sexual excess, failing to cherish one's own body; being trapped in destitution and suffering, lacking a free and easy demeanor; blaming Heaven and reproaching others, generating widespread regret and distress; dwelling on the past morning and worrying about tomorrow, planning for a century ahead throughout the year; domestic noise from family members, making everything seen and heard feel like thorns piercing the ears and eyes; believing in shamans and participating in sacrificial prayers, engaging in extensive slaughter of animals; discomfort during sleep and rest, lack of moderation in diet and drinking; taking excessive herbal decoctions, scouring the intestines and stomach, gradually depleting vital Qi (Yuan Qi); concealing the illness and avoiding doctors, leading to incorrect administration of treatments for cold, heat, deficiency, or excess; regarding death as a great suffering, harboring persistent thoughts of reluctance to part with relatives and kin.
Medicine was established by ancient sages to benefit future generations, concerning matters of life and death. To explore its subtleties, one must extensively read ancient and modern texts and devote oneself to deep comprehension.
In ancient times, there were Huangdi (Yellow Emperor) and Qibo; subsequent dynasties have never lacked medical experts. Shennong tasted hundreds of herbs, neutralizing seventy poisons in a single day, thus giving rise to the *Bencao* (Materia Medica). Huangdi engaged in mutual questioning with his teacher Qibo, exploring astronomy above, geography below, and the sufferings of the people in between, resulting in the creation of the *Lingshu* (Spiritual Pivot) and *Suwen* (Basic Questions). These works traced the changes of climatic influences (Yunqi), clarified the root and branch of meridians (Jingluo); discussed diseases by returning to their essentials, and formulated treatments that were appropriate. They were orderly and structured, brilliant and unconfused; their principles were extremely refined and subtle, knowing what others could not know, revealing what others could not reveal, truly serving as a grand classic for preserving life for all eternity.
Bianque inherited these ideas and developed them into the *Nanjing* (Classic of Difficult Issues). Huangfu Mi organized them into the *Jiayi Jing* (Systematic Classic of Acupuncture and Moxibustion), Yang Shangshan compiled them into the *Taisu*, and Wang Shuhe authored the *Maijing* (Pulse Classic). All these works were brilliant and became models of their time. Only Zhang Zhongjing, the Grand Administrator of Changsha during the Han Dynasty, traced origins and explored hidden depths, authoring the *Shanghan Lun* (Treatise on Cold Damage) and *Jingui Yaolue* (Essential Prescriptions of the Golden Cabinet). His formulas utilized variations of size, magnitude, odd, and even numbers, establishing the proper roles of sovereign, minister, assistant, and courier (Jun-Chen-Zuo-Shi) in herb combinations; this is indeed a secret passed down through millennia. However, regarding spring warmth, summer heat, heatstroke, and latent summerheat, there were still incomplete aspects. Fortunately, Liu Wansu wrote four books: *Yaozhi Lun*, *Yuanbing Shi*, *Zhige Shu*, and *Xuanming Lun*, supplementing what Zhang Zhongjing had missed. For instance, he modified Guizhi Mahuang Ge Ban Tang (Cinnamon Twig and Ephedra Half-Dose Decoction) into Shuangjie San (Double-Release Powder), and transformed Shizao Tang (Ten Jujube Decoction) into Sanhua Shenyao Wan (Three-Flower Divine Protection Pill). This can be described as surpassing the original master, truly benefiting the medical field. At the same time, Zhang Congzheng wrote *Rumen Shiqin* (Confucianism Serving One's Parents), categorizing formulas into sweating, vomiting, and purging methods. He stated, "Vomiting contains sweating, purging contains tonification; the Sages had only these three methods, no fourth method," which is an unchangeable truth. Thus, the world came to know the school of Liu and Zhang. Unfortunately, later scholars lacked precision and detail, using these methods improperly, until Li Dongyuan elucidated the principles of *Suwen*, adhered to Zhang Zhongjing's methods, and published ten books including *Jisheng Baci* to transmit to the world. Specifically in the category of internal injury, he established the *Piwei Lun* (Treatise on the Spleen and Stomach), creating formulas such as Buzhong Yiqi Tang (Tonify the Middle and Augment Qi Decoction), offering unique insights from antiquity and enlightening later generations. Later, Zhu Danxi studied cold damage, fire-heat, internal injuries, and miscellaneous diseases with meticulous care. Since people at that time were stuck in the rigid prescriptions of *Ju Fang*, he established various Yin-tonifying methods to correct biases. Although reasons varied, lamenting the lack of good methods to save people from premature death, he employed divine insight and wrote books to serve as standards for the world. As for Chao Yuanfang's *Bingyuan* (Source of Diseases), Sun Simiao's *Qianjin Fang* (Prescriptions Worth a Thousand Gold), and Wang Tao's *Waitai Miyao* (Secrets of the Outer Terrace), with their verbose language and extensive formulas, they deserve recognition as major works of past dynasties. For example, Tao Jian'an's *Shanghan Liushu* (Six Books on Cold Damage) seems superior to Zhu Fengyi's *Huo Ren Shu* (Book on Saving People). Because Tao Jian'an expounded upon what Zhang Zhongjing had not revealed, whereas Zhu Fengyi did not follow Yin-Yang as exterior-interior but interpreted Yin-Yang as cold-heat, a slight error led to a thousand-mile deviation; although he saved many, did he not kill many too? Xue Ji's *Waike* (Surgery) supplemented what Li Dongyuan left unfinished. Dai Yanli's *Zhengzhi Yaojue* (Essentials of Diagnosis and Treatment), Ge Kejiu's *Shiyao Shenshu* (Divine Book of Ten Herbs), Qian Ying's *Xiao'er Fanglun* (Discussion on Pediatric Formulas), Zhang Jingyue's *Dabao Lun* (Treatise on Great Treasure), and Zhao Yangkui's *Shuihuo Lun* (Treatise on Water and Fire) are like lighting a rhino horn at Niuzhu, illuminating everything without exception. Wu Youke's insights on autumn dryness were unique discoveries, and his new theories on plague were innovative creations; both are outstanding figures of recent times. As for the famous masters of our dynasty emerging continuously, inheriting the pulse diagnosis of former sages, all should be purchased and read to broaden knowledge. The writings of famous doctors are numerous enough to fill ox-carts and block paths, impossible to list completely; here we only mention the important ones. Those practicing medicine who explore these various works, combined with clinical judgment and adaptability to changing circumstances, can indeed be considered great men!
