The most fundamental and important medical treatment is science of acupuncture and moxibution, which is based on twelve channels theory. Meridian is a pathway that conveys material and energy in a human body. Twelve channels are divided into channels of hand & foot, channels of yin & yang. Yang channels are divided into taiyang, yangming, shaoyang, yin channels are divided into taiyin, shaoyin, jueyin. These are referred to twelve channels, and this theory is being used for diagnosis and test in oriental medicine. Meridian-doin-tajiquan is born, combining taijiquan which is recently handed down from China and Korean traditional method for health protection and treatment in ancient times and twelve channels, three yin & yang theory. I report this because meridian-doin-tajiquan which is non-medical and non-invasive way can be used in the treatment of disease, just like three yin & yang theory, the heart of the meridian theory, and Gehapchu theory are adjusted in the clinical science of acupuncture and moxibution. And I report this because I could mater the appropriateness of the traditional theory and I believed this corresponded with it, training myself by meridian-din-tajiquan. It is considered that this will be used in the treatment of pain disease of muscles and joints system and the diabetes, hypertension, obesity caused by stress in the near future.
