Acupuncture began in China thousands of years ago. It involves inserting fine needles at certain strategic points on the body, known as acupuncture points. According to traditional Chinese medicine, your body has more than 2,000 of these points. They are connected by pathways, called meridians, which are channels through which energy (called Qi) flows. Practitioners of Chinese medicine believe that stimulating these points is the key to correcting imbalances of Qi, and improving the flow of energy through the body.
