Modern sources state the therapeutic effects of moxibustion are: The initial effect of moxa causes vasoconstriction and the delayed effect causes vasodilation. This effect can be used to draw blood from one part to another. For example, in cases of congestive headaches or cerebral hemorrhage, moxa is applied to the extremities to cause vasodilation in the peripheral areas and thus the circulation to the head.
Reflexive effect – The heat stimulation of moxa has a reflexive effect which can arouse or sedate the functioning of organs and tissues, and this effect also enhances endocrine function. This reflexive effect is commonly used by stimulating corresponding organ points on the back to treat functional disorders.
Cardiovascular effect – Moxibustion has been shown to increase blood cell count, especially red blood cells (other sources say white blood cells). An increase in red blood cells causes a marked increase in plasma hemoglobin. In addition, moxa can reduce blood clotting time and increase the contractile strength of the cardiovascular system.
Immunological effect – Moxa can produce immunogens which stimulate and strengthen the immunological response. This increases the body’s resistance to disease and helps prevent illness. Moxa was commonly used in ancient times to prevent illness.
