This is an ancient Chinese therapy involving the insertion of very fine needles to stimulate vital "energy points", thus regulating the meridians or channels of the body. The goal is to promote the circulation of the blood and to unblock the stagnation of the so called "Qi"(energy)--the "vital force of life", and re-establish this energy balance. When the doctor carefully inserts the fine needles, You may feel a slight tingling and numb sensation, but you will feel very relaxed due to the physiological chemical change. The steel needles are sterile and are used once only, before safe disposal.
