Coarse Granulated Culinary Salt contains 84 trace minerals in almost identical ratios to what exist in our blood. The structure of the crystals is so perfect and size of the particles so small that they can be absorbed into the cell and metabolized by the body. This salt is the healthiest and tastiest salt on the market. We recommend you use only a ceramic salt grinder or salt mill to preserve the inherent vibrational pattern of these crystals. Exposure to metal for prolonged periods may alter the frequency pattern of salt.
