The salt is not only healing, but essential for many biological functions. Not any salt though.

Salt is an essential nutrient required for blood pressure regulation, transportation of nutrients and ion exchange. It is important to note that all salts are not equal. Processed (table) salt can indeed be harming as it contains chemicals, such as moisture absorbents, flow agents and sometimes fluoride. The salt processing involves drying the salt on high temperatures which radically alters the chemical structure of the salt.

On the other hand, the natural unprocessed salt is not only healing, but in fact essential for many biological functions.
Himalayan salt mined from ancient sea beds in Pakistan is one of the most appreciated as it is the purest salt available. Note that this salt does not supply iodide.
