Objectives : This paper compares and analyzes Liu Hejian's kidney fluid nourishing treatment methodology with Zhu Danxi's kidney tonifying treatment methodology. Methods : The two doctors' medical theories and treatment formulas were examined to study how their medical arguments manifested in clinical application. Results : Both doctors emphasized the kidney. Liu pursued the treatment of balance based on the theory of the original qi of the Taiyitianzhen(太乙天眞), while Zhu tried to prevent the frenetic stirring of the ministerial fire by restraining one's desires. In nourishing kidney fluid, Liu sometimes used hot medicinals to treat kidney deficiency patters, where medicinals that tonify the kidney fluid were not defined clearly. Zhu, on the other hand, defined formulas and medicinals that would tonify the kidney yin clearly. Conclusions : The tradition of emphasizing the body's yin qi based on the kidney has been continued from Liu Hejian to Zhu Danxi, during which the pathology of fire and heat were examined thoroughly. In clinical application, various and specific ways of controlling the fire heat were developed.

Objectives : The concept of hidden Yin in summer by Zhu Danxi deals with the relationship between summer heat disease and hidden yin inside of human body. This paper attempts to ponder upon the clinical issues around which the discussions regarding the topic unfolded, and upon the texts on which the doctors of the discussions based their opinions. Methods : First, Danxi's argument as discussed in $G{\acute{e}}zh{\grave{i}}y{\acute{u}}l{\grave{u}}n$ is analyzed to find out his understandings of clinical issues and his textual sources on which he based his new perspective. Moreover, the prescriptions that Danxi thought was problematic and the concept of hidden yin as it existed before the time of Danxi are reviewed, and these findings are used understand Zhangjingyue's ground of criticism against Danxi. Lastly, this paper contemplates how these opposing opinions may be helpful to the general principles of medical theories. Results & Conclusions : There was a trend before the time of Danxi of abusing drugs as prescription based on warm-heat, understanding that a human body has yin-cold during summer. However, Danxi brought forth a new concept of yin deficiency in order to correct people's misunderstanding. Despite his effort, Zhangjingyue and other doctors contemporary to Danxi emphasized on one hand that human body is placed on a state of external heat inside the cold, and on the another, criticized Danxi of failing to fully understand the principle of "Abandon the time and follow the symptoms", a principle which asserts that the cold and warm of medicine should be decided by the symptom itself and not by the season. The value of these contradicting assertions seems to hold true even to this day because it helps us understand that the principles of "Counting Season as a Treatment Factor" and "Abandon the time and follow the symptoms" could be applied with balance in conjunction with each other.

Objectives : Background research on the history of Huangbo's taste being written as 'pungent' was undertaken, after which its clinical meaning was examined from the medical perspective that was behind the medicinal's taste designation. Furthermore, through various understandings on the 'pungent' taste within the process of clinical application, the meaning of 'pungent' in Korean medicinal research was re-evaluated. Methods : Description of Huangbo's taste as 'pungent' as written in medical texts were chronologically examined to determine its origin. The clinical meaning of the pungent taste of Huangbo was examined within the broad medical perspective of doctors who were behind these descriptions. Results & Conclusions : The pungent taste of Huangbo was first described by Zhang Yuansu, followed by doctors of the Yishui School such as Li Dongyuan, Wang Haogu, etc., during which such knowledge was established and contributed to recognition of Huangbo's effect as tonifying Kidney deficiency and treatment of fire within water, after reaching the Kidney. Li Dongyuan understood the meaning of Huangbo's pungent taste as eliminating Yin fire and restoring the upward direction, ultimately restoring the general 'Rising-Falling-Floating-Sinking' mechanism within the context of his inner damage treatment. On the other hand, Zhu Danxi interpreted the pungentness of Huangbo based on his understanding of the nature of fire and action towards it. It seems as Huangbo's effects were understood within a relatively narrow frame, application of its pungent taste became vague, which gave rise to criticism by later period doctors, ultimately leading to an ambiguous understanding of the pungent taste of Huangbo.
