Dead Sea black mud has been used as a facial mask and skin curative since ancient times. Its therapeutic powers are associated with the names of the Queen of Sheba and Cleopatra, the Queen of the Nile. King Herod the Great came down to the Dead Sea seeking relief to the body and rest in the soul more than 2000 years ago. The dark color of the mud absorbs sunlight, thus heating the skin to which it is applied.
