Reflexology practitioners believe that there are major points in the hands and feet, with a rich supply of nerve endings that correspond to each organ and major muscle group in the body, and that stimulation of these points can have far-reaching effects. Reflexology practitioners use thumbs, fingers, and hands on specific points, without the use of oil or lotion. Pressure on these points releases restricted energy flow and improves circulation, resulting in increased oxygen and nutrient supplies to the brain and body. Detoxification is promoted, as well as a normalization of the functions of the organs, glands, and body structures. Energy flow throughout the body is restored to support optimum health. Endorphins are released providing pain relief and a feeling of well-being. People who benefit from reflexology report reduction or elimination of pain and feelings of deep relaxation.
