Reflexology

Reflexology is a complementary, biological, integrative health science, through which an exercise pressure is applied to reflex areas, formed by 7,2000 nerve endings in each hand and foot, encouraging improved instruction to each and every single gland, organ and part of the body, thus persuading the body to biologically correct, strengthen and reinforce itself, to reach balance, normalisation and homeostasis

Thus by working on one part of the body (foot area) there is an effect on another.  The goals of reflexology are to re-educate, re-pattern and recondition the nerves through the electrical system of the body.
