Primo vascular system

The primo vascular system was first described by Bonghan Kim in the early 1960s and originally referred to as the Bonghan Duct System but later renamed.

Kim himself disappeared in 1965 and his work was neglected for a while but recent work has confirmed many of his claims.

The system consists of small corpuscles connected together by transparent, fluid filled ducts, which form their own circulatory system and connect to all the major organs and almost every cell in the body.
Its precise function is unknown but it has been proposed as the physical organ of the acupuncture system.

Here we see the Bonghan ducts (BHD) and corpuscles (BHC) stained with blue dye alongside blood vessels on the surface of a rat’s intestine.

Without the stain, the ducts are transparent and almost impossible to see, even with a microscope.

  • The ducts cover all the major organs of the body where they will form a local network which is loosely connected to neighbouring networks
  • The vessels and fluid within them are electrically conductive
  • There is no central pump but there exists a pulse which is slower than, and independent of, the heartbeat. The fluid moves very slowly, around 0.2mm per second.
  • The ducts have been found in the middle of the arteries, in the lymph ducts, in the chambers of the heart, in the brain, on the skin and the surface of cancer cells.
  • Disruption of flow towards a cluster of cells results in cellular dysfunction and cell death
  • The fluid contains rod-shaped cellular nuclei aligned longitudinally and DNA that is outside of the nuclei.
  • The DNA is thought to act both as an antenna and a transmitter of light, collecting energy, from a wide range of frequencies, storing it and then emitting it at an appropriate wavelength.

The ducts consist of an outer sheath with several sub-channels.
Experiments suggest that this arrangement will conduct photons (i.e. light) along its length much like a fibre optic cable and that this light is somehow used as a long range communications system

The ducts connect areas on the surface of the skin with the deeper organs, which makes the primo vascular system a good candidate for the physical organ of the acupuncture system, with the Bonghan ducts comprising the meridians and biophotons being the chi energy that flows around the body.
