What is Acupuncture? Acupuncturists insert tiny hairlike needles into the skin to promote blood circulation to specific areas. This activates your body’s immune and nervous systems to reduce inflammation and release endorphins to alleviate pain. The history of acupuncture spans more than 2,000 years. Acupuncture helps to correct imbalances in the body caused by trauma, toxins, and stress. Once the body is in proper balance, the body will begin to heal itself.
