Since ancient times, the human outer ear, or auricle, has been considered a tool for healing, corroborated by recent scientific research. Various points on the auricle serve a double function, providing information on the condition of the internal organs and other parts of the body, while at the same time serving as a control panel that makes it possible to "change the settings" when there is a malfunction. Rather like a computer keyboard connected to a computer network, the outer ear is connected to the entire central nervous system, pressing on one of the auricle's "keys" affects the programming of the organism's self-regulatory system.
