Neural therapy according to Huneke uses the injection of local anesthetics for diagnosis and treatment. Depending on the situation, a stimulus (and/or the interruption of pathological stress) is given into the areas of the reflector segment or into the so-called "interference fields". This can trigger and maintain a disease or pain symptoms outside of every segmental order. Neural therapy targets autoregulatory mechanisms of the autonomic nervous system (especially the sympathetic nervous system). The theoretical principles for this include knowledge of neurophysiology and modern physics.
