Acupuncture is an ancient form of Chinese medicine which involves the insertion of fine needles at various points in the body to restore the flow of energy and stimulate healing. It is based on the philosophy that the universe, and the body are composed of two opposing energetic forces known as ying and yang. This energy flows through specific pathways in the body known as meridians. The balance of these energies is essential to a healthy body, and any disruption or blockage of energy leads to pain and illness. The safety and efficacy of acupuncture in treating a wide range of ailments has been well documented and publicized by the U.S. National Institutes of Health.
