"The elements in rock salt are not integrated into the salt's crystal grid, but cling to the outside surface and crevices of the crystalline structure. This is the fundamental difference between rock salt and crystal salt. A salt crystal manifests a superior structure. Due to this sublime form, the elements are biochemically available for our cells as are the individual frequencies or vibration patterns. Rock salt is a cheap alternative to table salt , and is at least a natural and wholesome product. Biochemically and biophysically, however, it is of little importance to our organism. We can only recieve the resonant effects of the geometric structure through the superior order or structure of a crystal and our cells can only absorb those elements that occur in an ional form. Only under considerable pressure can the elements be transformed into a specific size, making them ional, which enables them to pass through our cell wall. This is important because our cells can only absorb what is available organically or ionally. Therefore, we cannot absorb the minerals from our mineral water if they're not refined enough to penetrate our cell walls. And what doesn't get into our cells cannot be metabolized. Therefore, the best calcium is useless if it cannot be available to the body's cells. What we need is the organic, or ional state of an element, in perfect natural symbiosis with all it's associated elements, in order for our organism to make any use of it."
I buy it...look at the amazing properties of quartz, or any other crystal for that matter... :)
