Acupuncture improves the body’s functions and promotes the natural self-healing, by stimulating specific anatomic sites–commonly referred to as acupuncture points. Acupuncture can release blocked qi in the body and stimulate function, evoking the body’s natural healing response through various physiological systems. Modern research has demonstrated acupuncture’s effects on the nervous system, endocrine and immune systems, cardiovascular system, and digestive system. By stimulating the body’s various systems, acupuncture can help to resolve pain, and improve sleep, digestive function, and sense of well-being.
