Theories of acupuncture revolve around the idea of the yin and yang energy of the body. Needles are inserted into specific points (known as acupoints) to equilibrate this energy, or qi, which in turn will assist in our body`s own abilities to deal with various conditions. Since ancient times, acupuncture has been documented to be effective in pain control for a wide range of conditions. In addition, it is shown to have an effect in treatment of acne, allergies, anxiety, cosmetics, depression, indigestion, insomnia, migraines, tinnitus, and weight loss. It is a regulated profession in many countries around the world with the common designation associated with a licensed acupuncturist being a Registered Acupuncturist.
