Acupuncture has been studied in western countries for more than 50 years. Some of the researchers concluded that the acupuncture therapy is simply a kind of placebo effect. We have had several individual books and articles checked the reasons for how these researchers come to such a conclusion. In my opinion, their wrong conclusion is mostly due improper ways of acupuncture research design and practice. However we noticed that there is indeed a special kind of "acupuncture' system that might indeed mostly depends on such placebo effect. This acupuncture system is the Nora Five-element Acupuncture system. The presence of such acupuncture in practice might be one of the reasons that make some acupuncture researchers believe that acupuncture as a whole also a placebo effect. This book specifically discusses the reasons why this kind of acupuncture system might be more depending on placebo effect.
