What is Qi in Qigong? Where is it? What are the meridians mentioned?
Qigong's "Qi" exists in all parts of the human body. Because this energy was originally produced by human cells, cells can be regarded as biological factories here. People consume energy when they want to move, and cells produce all kinds of energy according to the needs of the human body, such as bioenergy, heat energy, electric energy and so on. Qigong is one of these energies that have not been really understood by human beings.
There are many inferences about meridians, and the most convincing theory is that meridians are actually the channels of human tissue fluid. As we all know, all cells in human body are immersed in tissue fluid. Here, we can make an analogy. Tissue fluid is equivalent to the sea, and meridians are ocean currents.
Generally, interstitial fluid does not flow, but for some reasons, interstitial fluid channels like ocean currents, that is, meridians, are produced. Because all cells in the human body are immersed in tissue fluid, these channels are responsible for transporting substances and energy to cells. Therefore, once the meridians are blocked, human cells will inevitably be damaged and pathological changes will occur. Acupuncture and cupping in traditional Chinese medicine rely on physical stimulation to dredge meridians.
Now, it seems that the most powerful evidence is that scientists injected a substance blocking the flow of tissue fluid at the location of meridians, and as a result, diseases caused by meridian blockage really appeared. (which meridians are blocked and what diseases will happen are recorded in Chinese medicine books in detail), which indirectly proves that meridians are actually channels in interstitial fluid. Qigong is actually a kind of energy produced by cells, which is transmitted through meridians. Without this energy, cells will lack vitality. Qigong therapy is a process in which one person transfers his energy to another. But what this energy is, there is no conclusion now.
