The world’s strongest sulfur brine used in our Physiotherapy Center comes from the “Malina” borehole in Solec-Zdrój. Classified as highly mineralized sodium chloride (brine) water, it contains the highest worldwide levels of active sulfur compounds, bromine, iodine, and boron.
The effectiveness of balneotherapy depends on the concentration of active sulfur compounds in the water. Using healing waters with high sulfur content (over 100 mg/L) ensures the best therapeutic results in spa treatments. Like all stimulus therapy, it requires a series of treatments, with effects lasting about a year after.
