Sulphide water used to treat has a concentration of sulphide ions of 103 mg/litre and is the strongest in Poland and one of the best in Europe. The diseases treated here include rheumatoid arthritis and osteoarthritis, ankylosing spondylitis, soft tissue rheumatism, post-traumatic conditions, discopathy, radiculitis, neuralgia, gout, skin diseases, respiratory diseases, cardiovascular diseases, poisoning by heavy metals and osteoporosis.
