[Review on experimental studies on Yin-yang theory of traditional Chinese medicine]

A series of experimental studies on TCM yin-yang theory performed by researchers of integrated western and Chinese medicine was aiming at the seeking of the real objective nature of yin-yang. However, no matter how you exclusively equalize any pairs of life phenomena or materials to yin and yang, you will mix up the relationship between generality and specificity, concrete and abstract, which would torture the real nature of things. The original intention of the researchers failed. However, during the process of experiments, they found the mechanism of medicines for strengthening yang and nourishing yin and its indications, and the obvious mutual restricting action of two agents for strengthening yang, Radix Aconiti lateralis preparata and Cortex Cinnamomi, which was unkown before, and this is even of more significant theoretical and clinical values. The proposal of "Adjustment of the Regular Threshold of yin and yang" will deepen the recognition on the mechanism of human regulation and this should gain positive appraisal.
