The mud used at our hotels comes from the famous Hévíz thermal spring in Hungary, or from sediment collected around the hot springs of the Váh River in Piešťany in Slovakia. In Sovata, Romania, the mud is excavated from the Bear Lake (Lacu Ursu) and contains salt. Of the mineral components of mud, iodine and bromine have a soothing effect, calcium, bromine and magnesium have a relaxing effect, and last but not least sulphur boosts local metabolism and suppresses inflammation.
