The medicinal water of Bük, surging to the surface from four wells, is considered almost miraculous for those suffering from calcification, cartilage abrasions, lower back pain, inflamed joints and chronic gynaecological diseases. The alkali-hydrogen-carbonated medicinal water, which contains a high level of calcium, magnesium and fluorine, has such a high mineral content that it is considered unique, even by international standards. It has an anti-inflammatory effect, supports bone metabolism, facilitates muscle activity and improves circulation. The medicinal water can even be used internally for water therapy to cure chronic gastritis, ulcer and in digestive disorders.
One of the special services offered by the Bük Thermal Bath is the prevention and treatment of osteoporosis, with traditional therapeutic and pampering spa treatments combined with painless bone density testing. Traditional massages and body treatments are supplemented by modern wellness treatments such the Alpine hay steam chamber or the wellness water bed.
