Health And Wisdom's crystal clear, odor-free Magnesium Oil (Magnesium Chloride) is a concentrated essence of pure sea water. Magnesium Oil does wonders as a foot soak, as a bath additive, and as a body spray to re-establish needed Magnesium in the body. Using Magnesium Oil daily aids in accomplishing the first stage of rejuvenation; raising DHEA & intercellular magnesium.* Although this product is named Magnesium OIL, the viscosity of this actually resembles that of WATER. The name was applied years ago as, once applied to the skin, there is an appearance of oil. When you pour some into the palm of your hand it almost 'rolls around' as oil would. Because of this, it mixes well with other liquids - well, except OILS!! In which case it separates just as water would when mixed with oils. If adding essential oils – shake before applying.
