Umbilical needling therapy of I-Ching is a new kind of acupuncture therapy conducted by Professor Qi Yong, based on and the comprehension ofZhou Yi, and enormous clinical experiences. It has now been accepted and usedgradually. Umbilical needling treatments of various diseases are with obvious effect. There are few clinical studies on the application of this therapy alone, and it is more combined with other therapies such as acupuncture, moxibustion and Traditional Chinese Medicine (TCM) for the purpose of healing. A wide range of diseases could be traeated by the combination of umbilical needling therapy and acupuncture. Umbilical needling therapy combined with moxibustion is often used to treat gynecological diseases. Internal diseases could be traeated by the combination of umbilical needling therapy and TCM. The umbilical needling therapy still lacks of systematic research and uniformed curative effect standard, and there are some difficulties and risks in practice. Therefore, its development has limitations. Besides, there are few studies on the "preventive treatment of disease" . The future research should base on the original theory, overcome the operational difficulties and carry out systematic research.
