The HOLOSAN Bioresonanz, which was developed in Austria, is a modern method for the effective holistic therapy of health issuses.

For the first time in energy medicine, HOLOSAN not only treats the organs but in addition also treats energy blocks in the autonomic nervous system and the central nervous system . The self regulation of the body is decisively activated, enhancing the ability of the body to heal itself. The causes of any illness are treated, rather than the symptoms or the individual organs.

The word “holosan”  first used by it’s inventors, the Doz.Ing. Johann Schreyer and Mag. Christof Ruby. It stands for the therapy goal of treating the whole person (greek holos = whole). Holosan Bioresonance works with a special Software and Hardware, a new diagnosis- and therapy machine of the energy medicine, which links the traditional complementary-medical system and modern results of research in one Synthesis.
