Acupuncture is one of the oldest healing practices in the world. It is part of the Traditional Chinese Medicine, a medical system that originated in China.
Acupuncture is based on the concept that disease results from disruption in the flow of qi (energy) and imbalance in the forces of yin and yang (the two opposed energetic forces). Acupuncture seeks to aid healing by restoring the yin-yang balance and the flow of qi. This is achieved by stimulation of specific points on the body by a variety of techniques, including the insertion of thin metal needles though the skin. It is intended to remove blockages in the flow of qi and restore and maintain health.
In the western culture and practice, acupuncture is considered part of complementary and alternative medicine. According to acupuncture theory, the acupuncture points lie along meridians along which qi, the human vital energy, is said to flow. There is no generally-accepted anatomical or histological basis for these concepts, and modern acupuncturists tend to view them in functional rather than structural terms.
There are about 400 acupuncture points found on the "twelve main meridians" and eight extra meridians which are described in classical and traditional Chinese medical texts, as pathways through which Qi and "Blood" flow. There also exist "extra points" not belonging to any meridian. Although there is no scientific evidence on how acupuncture works, a lot of studies had proved that it provides a consistent benefit and improvement to the patient’s health.
