Acupuncture is the insertion of very fine, sterile needles into specific pressure points of the body. Each needle is about as thick as a single strand of hair and the insertion is generally completely painless. Energy circulates throughout the body along well-defined pathways. If the natural flow of this energy circulation is disrupted, then the result can be pain or even disease. Acupuncture points are intentionally stimulated in order to balance the circulation of energy and to promote healing within the body and the mind.
