Clinical experimental research has concluded that the activities of blood, heart and the blood vessels change after acupuncture stimulation. Acupuncture strengthens the immune system by inhibiting or producing the formation of white and red blood cells, according to the disease being treated.

It controls the production of these cells. Acupuncture, especially electrical, can stimulate chemical components to normalize the blood, impacting cholesterol, globulin, albumin, thrombin and amylase levels in the serum, as well as potassium, sodium and calcium. Cholesterol can be greatly reduced. Acupuncture can regulate heart rate and can decrease the tension by relaxing the walls of the blood vessels in patients with vaso-constriction and vaso-dilation, thus regulating blood pressure.
