Reflexology is an alternative therapy based on massage of the feet.
The idea is that parts of the body can be mapped onto areas of the
feet. There is no known mechanism by which massaging the feet can
affect other parts of the body (other than the simple soothing and
relaxing effect that any massage gives) and no evidence that it
actually works.
Iridology is a remarkably similar notion. Diseases are detected and
diagnosed by examining the iris of the eye. A good critique of
iridology: Russell S. Worrall, “Iridology: Diagnosis or Delusion?”و
