Acupuncture is a system of diagnosing and treating pain and disease according to traditional Chinese medicine. Acupuncture is the gentle insertion of hair-fine needles into specific points on the body to stimulate the immune system and the flow of one Qi or natural healing energy. The stimulation of acupoints on the body as a means of treating disease is likewise transmitted through the meridians by regulating the Qi to influence physiological, emotional and psychological functions in the mind and body and to cure the disease. A person's health is influenced by the flow of Qi in their body. If that flow is insufficient, unbalanced or interrupted, illness may occur. Acupuncture is said to restore the balance.
