[Analysis on complex characteristics of traditional Chinese medicine property theory].

The traditional Chinese medicine property theory refers to a concept for medicines and their effects under the guidance of traditional Chinese medicine theories. The traditional Chinese medicine property theory studies the formation mechanism and the application regularity of traditional Chinese medicine properties, including four Qi, five flavors, meridian entry, direction of medicinal actions (upward, downward, outward and inward) and toxicity. Embryologically, the traditional Chinese medicine property theory is closely related to medicines and their effects and heavily influenced by philosophical thoughts such as yin-yang and five elements and comparative state, thereby showing complex characteristics. This mainly reflects in that: first, medical properties are formed from multiple sources, with non-unique determination approach in early stage and non-unique corresponding effects and actions; second, medical properties are expressed in multiple characteristics, with diverse representation indicators and factors influencing actual expressions. The modern studies on the traditional Chinese medicine property theory shall focus on these complex characteristics, give attention to the dialectical unity of medical properties and effects and look for individuality as well as generality.
