The resorts host many mineral springs with thermal (20-48°C), sulphuric, calcic, sodic, rich in bicarbonate waters known since the beginning of the millennium. The soothing effect of the waters on articular and muscular pain and on various rheumatic neuralgias accounts for the fame of cures in the resort for the treatment of inflammatory rheumatic diseases (rheumatic polyarthritis, rheumatoid spondylitis, conditions after acute articular rheumatism), degenerative and articular rheumatic diseases, central and peripheral neurological disorders, gynecological diseases, post-traumatic conditions, endocrine disorders.
