All five substances are interdependent. However Qi is central to each of them since it is both the prime activator as well as the recipient of other functions. Chinese medicine describes invisible Qi circulating along a system of conduits. This Qi is the vital energy which gives life to all living matter, in a way Qi conduits resemble those of a vascular nervous system. Then there is one midline meridian called, ventrally in the front, conception vessel and one posterior on the midline called governor vessel.
Acupuncture is a method of promoting natural healing and improving function within the body.
Chinese explain acupuncture as Qi or energy traveling through channels in the body surfaces. These channels called meridians are like rivers that run through the body and nourish the tissue. Any obstruction of movement of this energy is like a dam which backs up the flow in one part of the body and restricts the flow in other parts. Meridians can be influenced by acupuncture needling, unblocking the obstruction of the dams within the meridian circulation releasing the regular flow of Qi, blood and fluid, moisture through these meridians. Acupuncture treatments can be helpful for internal organs, connective tissue and promoting digestion absorption and energy production.
