Many people are asking us about the type of salt we use in salt therapy, so we decided to write about this.
Salt comes in many types but people are most familiar with the regular table salt and not as much with other types. Beside the regular table salt, there is a huge market with sea salt. Table salt and sea salt are highly processed and they contain lots of additives as flowing agents and not our best options. Sea salt may also contain pollutants depending on the places where it was harvested. However, many people are not aware of this.
Table salt is mainly sodium chloride combined with iodine such as potassium iodide or cuprous iodide, stabilizers for the iodine to prevent the potassium iodide from breaking down into iodine, and anti-caking agents. The anti-caking agents includes: calcium silicate, ferric ammonium citrate, magnesium silicate, aluminum calcium silicate, calcium phosphate, to name a few. Salt is hygroscopic, meaning it has the property to absorb water from the air. This water dissolves the salt, making the salt granules to stick together into a solid mass. An anti-caking additive, such as calcium silicate has the property of absorbing moisture from the air better than salt, and it does not dissolve in the water it absorbs. This help in protecting the salt from caking, and ensures it flows freely.
Usually all salt used in industry have these additives in different concentrations.
In salt therapy we use grey rock salt extracted using classical mining technology; the rock salt is only crushed preserving all the natural minerals in it. Sodium chloride together with the natural occurring minerals in rock salt have a synergetic effect on the respiratory system, providing great health results in salt therapy.
