For centuries several traditional medical systems have depicted the body’s energetic anatomy or the energetic body in books and charts. Medical traditions from China, India, Japan and Tibet, as well as other countries all have described energy channels, also called meridians (jing-luo) or nadis, along which vital energy of the body (qi, prana) flows. Today many researchers associate life-force with a bio-electrical, bio-magnetic, bio-photon and vibrational energy phenomenon. Life exists because of the life-force and vital energy running through it, animating the body, ensuring we can move, breathe, digest food, think and even feel.
These ancient descriptions of energetic anatomy have been traditionally accepted and used as a basis for acupuncture theory and practice for over 2500 years. Since the early 1950s, researchers have tried to prove the physical existence of these energy channels or meridians. Much of the scientific skepticism of acupuncture has been in part around the unknown anatomical foundation for the existence of meridians. However, recently scientists at in Korea have confirmed the existence what they refer to as the “primo-vascular system.” This ongoing research has begun to help scientifically validate the existence of energetic anatomy and the traditional meridian system.
North Korean scientist Kim Bong-Han proposed that he had found 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 these corresponded to traditional meridian lines depicted in ancient texts. The structures were called ‘Bonghan ducts or channels’, after his research. Now the existence of this system in various organs has been corroborated by further research and is termed the ‘primo-vascular system (PVS)’.
Korean researchers now believe this PVS is in fact a part of the physical component of the acupuncture meridian system. It has also been suggested that this system is involved in channeling the flow of energy and information relayed by biophotons (electromagnetic waves of light) and DNA.
Korean scientists have extensively studied the primo-vascular system with biophysical methods, by injecting a special staining dye which colored the vessels. By injecting the dye into traditional acupuncture points, they were able to see thin lines. These did not show up at non-acupuncture point sites where there are no meridians. The researchers discovered that the meridian lines are not confined to the skin but are in fact a concrete duct system through which liquid flows. According to this research the PVS integrates the features of the cardiovascular, nervous, immune, and hormonal systems. It provides a physical substrate for the acupuncture points and meridians. Announcements of the morphological architectonics and the function of the PVS fundamentally changed the basic understanding of biology and medicine because the PVS is also involved in the development and the functions of living organisms.
The following are selected articles on meridians, the primo-vascular system (PVS) and Bonghan corpuscles and ducts.
