Acupuncture is a treatment modality performed by inserting very fine sterile needles, not much thicker than a human hair, in specific locations on the skin, known as acupuncture points. The depth of needle insertion depends on the disease being treated and the location of the acupuncture point. For example, a shallow insertion is generally used for treating disease at the superficial level, i.e., initial stage of common colds and skin and muscle conditions. By contrast, deeper needle insertion is generally required for treating internal disease, e.g., organs and bones.

Acupuncture stimulation regulates the flow of Qi within the energy pathways, which is referred to as meridian or channel that interconnects throughout the entire body. The practice of acupuncture affects the endocrine and central nervous system, including responses from both the sympathetic nervous system (Yang) and the parasympathetic nervous system (Yin) to achieve equilibrium and promote the body’s innate healing ability.
