The mineral water unique in Europe bursts to the surface from as deep as 50-70 m, with an average temperature of 62.5°C. Its mineral content is about 1000 mg per litre. From a medical point of view, its most important component is carbon sulphide, which is under pressure, dissolved in water in a gaseous state. When it surfaces and is released from pressure, it begins to decompose into hydrogen sulphide gas – which gives the characteristic scent of the thermal water of Harkány.

The carbon sulphide is very actively absorbed into the body both through the skin and by inhalation: its absorption rate is 150 times that of other, more prevalent sulphuric compounds (sulphates).

Due to its unique properties, it is suitable for treating musculoskeletal, rheumatologic, dermatological and gynaecological diseases.
