What is Sulphurous healing mineral hypotonic water?

To explain this, we really have to break down each concept.

  • Hypotonic water: water with a low concentration of ions which helps it penetrate the skin through the mechanism known as osmosis.
  • Sulphurous water: water with a dissolved hydrogen sulphide (H2S) content greater than 1 mg/L. A smell reminiscent of rotten eggs is a typical characteristic of this type of water. This water is clear, soft and unctuous to the touch and has a salty taste. Another exclusive characteristic of sulphurous water is the presence of suspended bacteria from the sulphur cycle, which hugely enhance the therapeutic effects of these types of healing mineral water. This water is usually hot.
  • Sulphur: a mineral that is present in large quantities in the Earth’s crust. It fulfils a number of important functions in the body.

This is the water found in the “Font de la Tartera” spring, one of the 37 springs at the Caldes de Boí Spa.
