Abstract: The "greater triple energizer" theory is an innovation developed by Professor WANG Yongzhou, the founder of buccal needling, based on his inheritance of the traditional Chinese medicine (TCM) theory of the triple energizer. Through an analysis of the origins,connotations,and characteristics of the "greater triple energizer" theory, as well as its relationship with biological holography and psychosomatic medicine, it is proposed that holism is the compositional feature of the "greater triple energizer,that "ascending,descending,exiting,and entering are its vital characteristics,and that regulating qi movement is the mechanism of buccal needling based on this theory. The greater triple energizer theory, biological holography, and psychosomatic medicine together form a three-level theoretical system, which guides the treatment of diseases from form (limbs and joints), qi (zang-fu organs), and spirit( psychosomatic) respectively,giving rise to the distinctive and effective buccal needling system.
