There is a "vital energy" that is circulating between organs of the human body, that penetrates into every living cell. Whenever this energy is blocked, the zone of blockage will be affected, and the reflex zones such as your hands, can indicate the blockage of energy in different organs. Therefore, if someone has a problem in a particular organ, a reflexologist will press on the corresponding reflex zone or zones, and the person will sometimes experience pain. This pain is claimed to originate from the deposition of crystals in the reflex zone and, with massage, these crystalline structures can be broken down and the pain relieved. Simultaneously, the pressure applied to the reflex zones by the reflexologist is claimed to pass through the nerves to dissipate energy blocks.
