Abstract: This paper introduces the current research status and existing problems of the theory of traditional Chinese drug properties, as well as the specific meanings and theoretical sources of the "eight methods of discriminating drugs". The "eight methods of discriminating drugs" theory analyzes drugs through the eight dimensions of body, color, qi, taste, form, nature, energy, and power, attempting to find the fundamental composition laws and deconstruction methods of traditional Chinese drug properties. It is believed that the "eight methods of discriminating drugs" theory has established a comprehensive system for evaluating the properties of traditional Chinese drugs at the level of traditional Chinese medicine theory, which can be used as a reference for modern researchers of traditional Chinese drug property theory in explaining the "nature-effect-use" relationship of traditional Chinese drug and establishing a diverse theoretical research system for drug properties.
