Traditional chineese medicin states that the most important thing about having a healthy body is the "Chi". The chi is life energy and it has an effect on every little cell in the body. If the chi is blocked or out of balance then the body will show signs of this. I my case my vein has been narrowed and this was because I had a blockedge in my "Chi". When my chi has been balanced it will actually effect the cells of my body to open up and my blood will flow better. The flow of the chi is equal to the flow of the blood.
Acupuncture straigtens out the chi and improves circulation.
It is very relaxing and extremely helpfull.
