He stated the effects of the Sea and that many travelers in the region take as much of the salt from this mainly because of its healing and medicinal powers.

If you want to buy these products, make sure that you check the labels which indicate the place where it was made. It should be "made in Israel" or "made in Jordan". These are the only two countries that are nearest to the Sea and the only ones who have access to it.
