Tigerlillies salts are imported from the waters of the Dead Sea. They are unique in that they contain 27% of various salts as compared to 3% in normal seawater. Further, while sodium accounts for approximately 80% of the salt content of normal seawater, it comprises much less of the salt total in water from the Dead Sea. The balance of the salts in Dead Sea water is magnesium, potassium, calcium chloride, and bromides. All Natural.
