Acupuncture works by stimulating the body's natural healing process through the insertion of fine needles into specific points along the meridian lines. The acupuncturist will then manipulate the needles to stimulate the flow of qi and promote healing.Acupuncture is one of the oldest forms of medicine practiced today. It is based on the theory that there are energy channels within our bodies, called meridians, which carry life force or Qi. When these channels become blocked due to injury, illness, stress, or other causes, we may experience symptoms such as pain, numbness, tingling, weakness, etc.
