A hypertonic sodium chloride spring, salty with a distinct sweet note in the certificate's sensory test. Dissolved solids reach about 14.8 g/kg, so the water is richly mineralized and leaves a salt veil on the skin that keeps warmth in long after the bath. At the wellhead it emerges colorless and clear with visible gas evolution — free CO₂ measures 517.5 mg/kg — and the lab notes the water turns pale yellow and turbid within hours of sampling. The appended indications table documents it for cuts, peripheral circulation disorders, cold sensitivity, and dry skin.
