Zhang Zhicong Six By Gasification Doctrine

Based on the Yunqi theory (doctrine on medical meteorology corresponding to seasons' alternation in acient China) form Huangdi Neijing (The Yellow Emperor's Canon of Internal Medicine), advocated by medical scholar Zhangzhichong in Qing dynasty, the physiology and pathology changes manifested in Shang Han Lun(Treatise on Cold Damage) should be mostly ascribe to Qi activity, which is classified into six categories with the title'Liu Jing(Six Channels)'.Henceforward this view named'Liujing Qihua theory'was supported by the majority of later medical scholars and Zhang's opinion is considered to be an important item in the study of Cold Damage, which is significance to the treatment of various diseases caused by both internal and exogenous pathogenic factor, such as cold damage disease,plague and so on.Furthermore, the academic achievement of Dr. Zhang Zhichong is comprehensive.He was versed in the study of TCM classic, like Huangdi Neijing, Jinkui Yaolue (Synopsis of Prescriptions from the Golden Chamber), Shennong Bencao Jing (Shennong's Classic of Materia Medica) and was skillful in materia medica.However, it's regretfull that modern reaserch on him is ordinary and abbreviated, so more attention and further study should be paid to his academic viewpoint.Founded on the literature reviews and historical records, the material relative to culture, society status and historical condition in Zhang Zhichong'time was collected and a further analyze could be deduced on this special background information, which was favourable to the innovation of his opinion mentioned above. Besides, a trace on the previous discussions by researchers of Qi activity and Yunqi Thoery in different dynastys was also done.With the comparison to these associated viewpoints, the content of Liujing Qihua theory was systematicly elucidated and the achievement or diavantage of this theory would be summarized. Thus, the content of this thesis could be divided into 4 parts as follow:Partâ… . Base on the background information associate with Zhang Zhichong, such as climate condition, society status, culture, academic school viewpoint, and some factors could be considered to be in the promation of Liujing Qihua theory:the Neo-confucianism in Song and Ming dynasty, a great importance was attached to the medicial Classic, the cold climate and plague in Ming and Qing dynasty.Partâ…¡. Leaded by the Yunqi theory in Huangdi Neijing, founded on previous discussions by researchers of Qi activity in different dynasty, with the comparison to these associated viewpoints,the content of Liujing Qihua theory was systematicly elucidated.Some medical cases were also attached in this part to exemplify this theory for the clinical treatment.Partâ…¢. In this part, form Zhang'study on the property, usage, pharmacological action of materia medica,25 herbs were selected form Shang Han Lun as auxiliary research of Liujing Qihua theory.Part IV. In order to exemplify its significance to the clinical usage,12 formulas were chosen form Shanghanlun Jizhu (The Variorum on Shanghanlun, which is the masterpiece of Dr.Zhangzhi Chong) to analyse the correlation between materia medica and correspoinding syndrome in Zhang Zhichong's view.In conclusion, based on the medical classics and previous scholars'study, Zhang's 'Liujing Qihua theory'is a profound viewpoint which is benefical to both clinical practice and academic development of Shang Han research.His remarkable contribution should be own to his comprehensive knowledge on Confucianiasm and strictly follow an factualistic and observational way to pursue academic investigation.His experience could be serve as a case to manifest TCM characteristic named as "Corresponding between Human and Nature", "Unity between Medicine and Pharmacology",and illuminated to the discussion of TCM original thinking style.
