Therapeutic properties of water and mud indications and counterindications

Natural therapeutic properties of water

The water of the Istrian thermal resort is sulphurous, thermal, with natural radiation and important contents of sodium, calcium, chlorine and other minerals. The temperature of the water is 32-34°C. The content of sulphur is 33-38 mg H2S/kg and radioactivity is 623 Bg/L. Such composition of water has been maintained for years with minor variations depending on the rainfall. Sulphur and natural radioactivity in the water have a beneficial effect to inflammation, reduce pain and improve circulation and metabolism.

Its extraordinary therapeutic properties distinguish the Istrian thermal resort from other thermal springs and place it at the third position of the European rank-list. Because of its strong therapeutic properties it is recommended one bath per day no more than half an hour.

Curative mud

Curative mud is prepared by long-term maturing in a particular manner using thermal and mineral water and mud. It is applied directly to the skin (thickness of layer is 3-4 cm, temperature about 40°C) and then washed out under strong jet of the mineral water. Total time of the peloid therapy is about 40 minutes. Its main effect is thermal owing to the thermal properties of the curative mud, and chemical as a result of the effects of sulphur and other minerals.



The healing effect of sulphur fumes on the respiratory system has been known since ancient times, and inhaling sulphuric vapour can be considered as one of the most ancient forms of inhalation therapy. Certain sulphur compounds have a beneficial effect on allergic reactions by increasing the body’s resistance, while radon has a beneficial effect on inflammatory processes in the sinuses and upper and lower respiratory tract.
