In acupuncture, the nervous system is stimulated by thin, metallic, needles at points known as acupuncture points. It causes the system to increase the release of natural painkillers such as endorphins and serotonin, in the pain pathway of the brain and the spinal cord.
Aside form over 5000 years of empirical study, Acupuncture has now been approved for medical use in over forty medical problems, including allergies, respiratory conditions, gastrointestinal disorders, gynecological problems, nervous conditions, and disorders of the eyes, nose and throat, and childhood illnesses, among others. Its activity in these different symptoms suggests that acupuncture does not have a single mode of action but a range of effects on various functions which increases the complexity of both understanding and researching acupuncture.
Despite medical uncertainty of exactly how Acupuncture can provide so many benefits, there is plenty of evidence that supports its use in nervous system and muscular conditions, immune deficiency, in the management of stress and many other conditions.
