If reflexology does not treat disease, what can it do for me? Medical doctors agree that over three fourths of our health problems can be linked to nervous and physical tension. By reducing stress and tension, reflexology improves blood and lymph circulation, strengthens the functioning of the immune system, improves assimilation of nutrition and elimination of toxins, and calms the nervous system. In these ways, reflexology facilitates the body's natural healing processes and thereby enhances the body's health and vitality.
