Reflexology is also known as zone therapy. It involves massaging, holding, squeezing, and pushing on certain parts of the body, primarily the foot although reflexology may also be used on the hands or ears. In reflexology, certain points on the body are suspected to have beneficial effects throughout other areas of the body when massaged.
In reflexology, there are pressure points on the feet that have direct correlation to the flow of energy through the body, including to your organs. When the flow of your life's energy, or Qi (or more commonly, Ch'i), is flowing properly throughout all the organs in a balanced and fluid manner, then overall health and well-being is present in the body.
For instance, pressure applied to the very center of the sole affects the functioning of the bladder and kidneys. This is why this method is used to help alleviate symptoms for a number of medical conditions as a supplement to other treatments or as alternative care.
