What are meridians?

Meridians are the channels that run qi and blood, connecting zang-fu organs, body surface and various parts of the body, and are the regulation system of human body functions. Meridian is also the basis of human acupuncture and massage and an important part of Chinese medicine. ? Meridian theory is one of the cores of the basic theory of traditional Chinese medicine, which originated in ancient times and serves today. In the long medical history of more than two thousand years, it has been playing an important role in safeguarding the health of the Chinese nation.

Meridian is the channel through which the human body runs qi and blood. It includes two parts: meridians and collaterals, in which the longitudinal trunk is called meridians and the branches of the network divided by meridians are called collaterals. The main contents of channels and collaterals are: the twelve meridians, the twelve meridians, Eight Meridians of Strange Meridians, Fifteen Collateral Meridians, the twelve meridians and Twelve Skin Branches. Among them, twelve meridians are the main meridians and fifteen meridians are the main meridians. They intersect vertically and horizontally and spread all over the body, connecting the inside and outside of the human body, viscera and limbs into an organic whole.

Extended data:

In the mid-1980s, the study of meridians was highly valued by the state, and the first national-level meridian project in China was born, that is, the "Seventh Five-Year Plan" national key project-"objective detection of routes along the Fourteenth Meridian". At this time, scientists are not satisfied with using simple means such as subjective perception to explain the existence of meridians, but try to prove the objective existence of meridian routes by more scientific means. The most important discovery in this period is that the trajectory of isotopes moving along the meridian line was photographed by γ camera.

Using biophysical means to study meridians has become a major feature of meridian research. Researchers have found that meridians have physical characteristics such as low resistance, high-pitched vibration, good acousto-optic heat conduction and isotope migration. These works are summarized in an important book on the study of meridians, Acupuncture and Biophysics of Meridians, which is a milestone in objectively confirming the existence of meridians.
