The balneological analysis of the University of Graz confirms that the iron–chloride–iodide thermal brine of the thermal salt spring Speltenbach has a scientifically recognized curative effect or that such an effect is anticipated.

The total mineralization of the water is just above 40 g/kg and the value determining substances are 94.0 equiv.% for sodium and 96.1 equiv.% for chloride. The concentration of iron is 11.1 mg/kg and 7.6 mg/kg for iodide. The Speltenbach curative water can be described as a high-level brine due to its high mineralization (15g/kg sodium; 23 g/kg chlorine).

The curative brine has an iodide concentration of 7.6 mg/kg (a minimum concentration of 1mg/kg is used to define iodine springs). During bathing, the iodine reabsorption by the intact epidermis is comparably low. A very high amount of iodine, however, is stored in the skin within storage areas in the so-called horny skin, which provide an effective post-reabsorption for hours or even days.

1000 g of HEALING SALT are produced from 24 litres of thermal water through the process of vacuum evaporation and contain:

The HEALING SALT extracted with the aid of vacuum evaporation is a very stable product and is suitable for both shipping and storage. Its chemical and physical properties are – in comparison to the brine – not altered in a manner which significantly influences the medicinal benefit.
