Sulfurous springs appear near areas where it still exist volcanic activity more or less intense. It is the case of the sulfur springs around the Balvanyos resort, located in the southern part of the Bodoc Mountains, Romania. Their water continuously stutters and has a distinct odor of “rotten egg”. When the atmospheric pressure decreases (usually, when is rainy weather), it significantly increases the emanation intensity. Since ancient times, the water baths are successfully used for therapeutic purposes – in the treatment of the cardiovascular diseases such as the varicose veins, hypertension, rheumatic diseases and cutaneous mycoses.
