The curative properties of the Dead Sea have been recognized since the days of Herod the Great over 2,000 years ago.
The Dead Sea is 80km (50 miles) long, approximately 14km (9 miles) wide. The northern and larger part is very deep, reaching at one point a depth of 430m (1320 feet). The southern bay is, on the contrary, very shallow, averaging hardly a depth of 4m (13 feet).
Dead Sea mud, or pelloid, is mineral-rich alluvial sediment, saturated with sulphide components. It holds heat well and can be smeared on the body to cleanse the skin, as well as relieve arthritic and rheumatic pain.
