The Dead Sea lies at the bottom of a tectonic trench formed more than two million years ago. Since this trench is more than 400 meters below the Mediterranean, it is, incredibly, the lowest point on Earth. The Dead Sea, actually a lake, has no southern outlet, no flow. Nothing lives in this water; no fish, algae or mollusks. The closest American parallel is the Great Salt Lake, which also features spectacular saline formations. With a greater solid content than any other body of water – 30% compared to about 6% solids in ocean water – a uniquely dense combination of potassium chloride, magnesium chloride, sodium chloride, calcium chloride and bromides has formed. Ocean salt is more than 97% sodium chloride, but Dead Sea Salt has a very low concentration of sodium chloride, and a high proportion of magnesium and potassium. This unique chemistry produces a unique bath treatment: Magnesium Chloride (MC12) 34.0% Potassium Chloride (KC1) 23.0% Calcium Chloride (CaC12) 0.7% Bromides (as Br) 0.4% In the 1950’s, physician studies concluded that authentic salts extracted from the Dead Sea have a proven therapeutic effect on skin ailments such as psoriasis and eczema. Regular bathing in these salts was shown to provide great relief from such psoriasis symptoms as itching, burning, flakiness and muscle and joint aches. Beyond these therapeutic effects for the skin, the University of Jerusalem has provided evidence that Dead Sea Mineral Salts also stimulate circulation and encourage the skin to renew itself. In addition, subcutaneous penetration helps relieve aches and pains in joints and muscles, providing much relief for those whom experience rheumatism and arthritis. A sense of deep relaxation is derived from frequent baths in Dead Sea Mineral Salts.
