Gesundes Wissen is a naturopathic practice and remedy manufactory in the heart of Heiden. Led by Peter Hämmerle, the practice combines centuries-old empirical knowledge of Traditional European Naturopathy (TEN) with modern scientific findings. The focus is on treating the person as a whole rather than just an isolated clinical picture. In addition to individual therapeutic concepts such as phytotherapy, hydrotherapy, and manual techniques, the practice produces its own house specialties.
