凡古今病名率多不同，缓急寻检，常致疑阻。若不别判，何以示众？自如世人呼阴毒伤寒为
剧病，实阴易之候，命一疾而涉三病。以此为治，岂不甚远！殊不知阴毒、少阴、阴易自是三候，
为治全别。古有方证，其说甚明。今乃混淆，害人最急。又如肠风、脏毒、咳逆、慢惊，遍稽方
论，无此名称。深穷其状，肠风乃肠痔下血，脏毒乃痢之蛊毒，咳逆者，哕逆之名，慢惊者，阴
痫之病。若不知古知今，何以为人司命？加以古人经方，言多雅奥。以痢为滞下，以 为香港脚，
以淋为癃，以实为秘，以天行为伤寒，以白虎为历节，以膈气为膏肓，以咳嗽为咳逆，以强直为
痉，以不语为喑，以缓纵为痱，以怔忪为悸，以痰为饮，以黄为瘅。诸如此类，可不讨论，况病
有数候相类，二病同名者哉？宜其视伤寒、中风、热病、瘟疫通曰伤寒，肤胀、鼓胀、肠覃、石
瘕率为水气。疗中风专用乎痰药，指带下或以为劳疾。伏梁不辨乎风根，中风不分乎时疾。此今
天下医者之公患也。是以别白而言之。（《千金方》）
太史公曰∶凡人所生者神也，所托者形也。神大用则伤形，大劳则敝形，神离则死，故圣人
重之。由是观之，神者，生之本也；形者，生之具也。不先建其神，而曰我有以治天下，何由哉？
（秦汉文）
Generally, ancient and modern disease names are mostly different. In urgent situations, searching for them often leads to doubt and obstruction. If not distinguished and judged, how can one demonstrate to the public? Since people call Yin-Du Cold Damage (Yin-Toxin Cold Damage) a severe disease, it is actually the manifestation of Yin-Yi (Post-illness Sexual Transmission Syndrome), using one disease name but involving three diseases. Treating based on this, isn't it far off! One should not know that Yin-Du, Shao-Yin (Lesser-Yang), and Yin-Yi are originally three different manifestations, with completely different treatments. Ancient texts have prescriptions and syndromes, and the explanation is very clear. Now they are confused, harming people most urgently. For example, Chang-Feng (Intestinal Wind), Zang-Du (Visceral Toxin), Ke-Ni (Coughing Upwards/Reverse Qi), Man-Jing (Slow Convulsion), after checking prescriptions and theories everywhere, do not have these names. Deeply exploring their conditions, Chang-Feng is bleeding from intestinal hemorrhoids, Zang-Du is the gu-toxin in dysentery, Ke-Ni is the name for Yue-Ni (Hiccup/Reverse Qi), and Man-Jing is the disease of Yin-Xian (Yin Epilepsy). If one does not know the past to understand the present, how can one be the master of life for others? Furthermore, ancient classic prescriptions use elegant and profound language. Calling dysentery "Zhi-Xia" (Stagnant Downward Flow), calling podagra/jam-jiao "Xiang-Gang Jiao", calling Lin-Syndrome (Dysuria) "Long", calling Excess "Mi" (Constipation), calling Tian-Xing (Epidemic Disease) "Shang-Han" (Cold Damage), calling Bai-Hu (Tiger Stride/Joint Pain) "Li-Jie" (Perforating Joint Disease), calling Ge-Qi (Diaphragmatic Qi Stagnation) "Gao-Huang" (Deep-Seated Disease), calling cough "Ke-Ni", calling stiffness "Jing" (Spasm), calling muteness "Yin", calling flaccidity "Fei" (Atrophy), calling palpitations "Ji" (Palpitation), calling phlegm "Yin" (Fluid Retention), calling yellowing "Dan" (Jaundice). All such cases, how can they not be discussed, let alone situations where several manifestations are similar or two diseases share the same name? It is appropriate to refer to Shang-Han (Cold Damage), Zhong-Feng (Wind Strike), Re-Bing (Heat Disease), and Wen-Yi (Plague/Epidemic) all as Shang-Han; and Fu-Zhang (Skin Distension), Gu-Zhang (Drum Distension), Chang-Qin (Intestinal Mass), and Shi-Jia (Stone Mass) generally as Shui-Qi (Water Qi). Treating Zhong-Feng specifically uses phlegm-resolving medicines; pointing out Dai-Xia (Leukorrhea) sometimes considers it Lao-Ji (Consumption Disease). Fu-Liang (Hidden Beam Tumor) is not distinguished from Feng-Gen (Wind Root); Zhong-Feng is not distinguished from Shi-Ji (Epidemic Disease). This is the common malpractice of doctors throughout the world today. Therefore, I clarify and explain separately. (From *Qianjin Fang*)
The Grand Historian said: What man generates is Shen (Spirit/Mind), what he entrusts is Xing (Form/Body). If Shen is used excessively, it injures Xing; if labor is excessive, it ruins Xing; when Shen departs, death occurs. Thus, the sages value it highly. From this perspective, Shen is the root of life; Xing is the vessel of life. Without first establishing Shen, how can one say they have the means to govern the world? (Qin-Han Text)
