Traditional Chinese Medicine (TCM) has a history of more than two millenniums. It has been a common practice in China, Taiwan, Japan and Korea and is becoming increasingly popular worldwide in recent decades However, there is no general consensus for treatment of many diseases among TCM practitioners. In some specialties, such as neurology, there is not enough well documented case reports for practitioners to make reference with. Different practitioners may give different opinions according to their own experience and patients often feel frustrated about that.
