Is human life without salt imaginable? Probably not. Salt symbolizes life itself. Basic physiological functions depend on a balance between salts and liquids in the body. When the balance is upset, disease may occur.
Salt has been an essential, virtually omnipresent, part of medicine for thousands of years. It has been used as a remedy, a support treatment, and a preventive measure. It has been taken internally or applied topically and been administered in an exceedingly wide variety of forms.
