There are so many uses for salt other than just in food!

Salt is formed when acidic and alkaline materials combine and are neutralized. The resulting neutral pH is unique and offers many uses.
Because of its neutral pH, salt is also used purposely to kill off vegetation, and does a better or worse job at this depending on how sensitive the vegetation is to shifts in pH.
Salt also is a good non-abrasive scrubber and provides many uses in the home and for the body for this reason.
