"nThere are two mutually supportive systems in medical profession: modern medicines and traditional medicine. The current status is that although the modern medicine occupies the major position in healthcare system, the therapeutic effect of traditional medicines should not be omitted. If all of them merged and unified as one, it will be beneficial to the development of human medicine. In this paper, the integration of Traditional Chinese Medicine (TCM) and modern medicine was exemplified to elucidate the mutual complements, mutual benefits of traditional medicines and modern medicine to maintain the unification of human medicine via the development of molecular biology, cytology etc. We believed that TCM theory may share the same mechanism with western medicine at some extent which need to be explored in the future research. In our point of view, although the road may twist and turn, the results are promising.
