Acupuncture is used to encourage natural healing, improve mood and energy, reduce or relieve pain and improve function of affected areas of the body. It is safe and effective and is often successfully used as an alternative to medications. A vast body of scientific literature exists that acupuncture needling induces a chain of events that results in the release into various parts of the nervous system of neurotransmitters and neurohormones that have widespread and measurable effects on pain.
