Tskhaltubo is famous for its radon-carbonate mineral springs, having unique physico-chemical and medicinal properties. whose natural temperature of 33-35°C enables the water to be used without preliminary heating.
The wide range of therapeutic effects of the Tskhaltubo mineral water is determined by a favourable combination of it`s physico-chemical components (They fall under the category of lowradon (74-148 Bq/I) chloride-pydrocar-bonate-sulphate sodium-magnesium-calcium weters whith an overall mineral content of 0.7 to 0.8 grammes per litre. the total daily yield of the springs is 18 to 20 million litres).
The resort’s focus is on balneotherapy for circulatory, nervous, musculo-skeletal, gynaecological and skin diseases, but since the 1970s its repertoire has included “speleotherapy”, in which the cool dust-free environment of local caves is said to benefit pulmonary diseases. A study of the physico-chemical and medicinal properties of this natural factor was launched by the Georgian Resort Treatment Research institute in 1970.
