Dead Sea salt
The Dead Sea's mineral composition varies with season, rainfall, depth of deposit, and ambient temperature. Most oceanic salt is approximately 85% sodium chloride (the same salt as table salt) while Dead Sea salt is only 30.5% of this, with the remainder composed of other dried minerals and salts. Major ion concentrations in the water of the Dead Sea have given the following results (which do not necessarily reflect those of Dead Sea salt):
|Chloride and Bromide||230,400|
- Expressed in equivalent oxides, as appropriate; for example the neutral sodium sulfate (Na2SO4) would be analyzed as basic sodium oxide (Na2O) and acidic sulfur trioxide (SO3), neither which occur in free form in this mud.
Dead Sea salts have been claimed to treat the following conditions:
Common skin ailments – for treating skin disorders such as acne and psoriasis which may be relieved by regularly soaking the affected area in water with added Dead Sea salt. The National Psoriasis Foundation recommends Dead Sea and Dead Sea salts as effective treatments for psoriasis.  High concentration of magnesium in Dead Sea salt may be helpful in improving skin hydration and reducing inflammation, although Epsom salt is a much-less-expensive salt that also contains high amounts of magnesium and therefore may be equally as useful for this purpose.
