Reflexology is a treatment system that uses reflex zones that have been mapped in the feet, hands, and ears. The feet are the most common area that practioners are trained in. The therapist will use the mapped reflex zones to treat conditions throughout the body by applying very specific pressure to the correct spot on the foot, hand, or ear. The reflex points are believed to use nerve pathways to create affects in corresponding areas of the body. The earliest references to reflexology are almost 5000 years old. Reflexology can be done as a stand-alone therapy or integrated with other treatment modalities.
