The Original FX Mayr is a medical wellness resort located on the shores of Lake Worthersee in Carinthia, Austria. The property was founded in 1976 by German entrepreneur Rolf Deyhle as the first permanent center dedicated to the FX Mayr cure, a therapeutic method developed by Austrian physician Dr. Franz Xaver Mayr beginning around 1901. Dr. Mayr's approach is based on the principle that intestinal health is fundamental to overall health and that most chronic conditions can be traced to digestive dysfunction. The clinic's first medical director was Dr. Erich Rauch, a student of Dr. Mayr.
The resort occupies a hillside position overlooking the southern shore of Lake Worthersee, surrounded by the Carinthian Alps. The core program follows the Mayr diagnostic and therapeutic protocol, which includes intestinal cleansing, dietary modification (beginning with a restrictive 'milk and bread' diet and progressively reintroducing foods), manual abdominal therapy, and supplementation. Modern iterations of the program incorporate blood analysis, food intolerance testing, infusion therapy, and movement programs. Standard program durations range from one to three weeks, with a minimum recommended stay of six days.
The Original FX Mayr maintains its identity as the direct successor to Dr. Mayr's original therapeutic methods, distinguishing itself from other Mayr-inspired clinics through its unbroken institutional connection to the founder's work. The resort has undergone multiple renovations and modernizations while preserving the medical fundamentals of the cure. Accommodations include 60 rooms and suites. Weekly rates for the diagnostic and therapeutic program typically start above 3,500 euros, including medical consultations, treatments, and full board.
