Recently scientists at Seoul National University confirmed the existence of meridians, which they refer to as the “primo-vascular system.” They say that this system is a crucial part of the cardiovascular system. Previously, North Korean scientist Kim Bong-Han proposed that he had found meridians in the early 1960’s. Dr Kim Bong-Han showed over 50 years ago that new tubular structures exist inside and outside of blood vessels and lymphatic vessels, as well as on the surface of internal organs and under the dermis. He believed they were the traditional meridian lines. The meridians were called Bonghan ducts or channels, after his research, but now the existence of this system in various organs has been corroborated by further research.
The current Korean researchers now believe the primo-vascular system is in fact the physical component of the Acupuncture Meridian System. And it has also been suggested that this system is involved in channelling the flow of energy and information relayed by biophotons (electromagnetic waves of light) and DNA.
