Salt isn’t just for cooking it has great medicinal purposes and many other uses for around the house.
Salt has been used for centuries for both culinary purposes and for medicinal use.
So what is salt?
Common salt, or sodium chloride, is the chemical compound NaCl. Salt occurs naturally in many parts of the world as the mineral halite and as mixed evaporites in salt lakes. One of the best sources of this natural nutrient is Seawater. Containing lots of salt, it has an average of 2.6% NaCl (by weight), or 26 million metric tons per cubic kilometer. That’s 120 million short tons per cubic mile, an inexhaustible supply (Note: Seawater also contains other dissolved solids; salt represents about 77% of the Total Dissolved Solids). Underground salt deposits are found in both bedded sedimentary layers and domal deposits. Salt deposits have been found to have encapsulated ancient microorganisms including bacteria. Some salt is on the earth’s surface, such as the dried-up residue of ancient seas like the famed Bonneville Salt Flats in Utah. Salt even arrives on earth from outer space, and its presence on the planet Mars has led scientists to think life may exist there (or at least be supportable). Amazingly, surface salt deposits and man-made saltworks can even be seen from space.
Salt was in general use long before history, as we know it, began to be recorded. Some 2,700 years B.C.—about 4,700 years ago—there was published in China the Peng-Tzao-Kan-Mu, probably the earliest known treatise on pharmacology. A major portion of this writing was devoted to a discussion of more than 40 kinds of salt, including descriptions of two methods of extracting salt and putting it in usable form that are amazingly similar to processes used today. Chinese folklore recounts the discovery of salt. Salt production has been important in China for two millennia or more. And the Chinese, like many other governments over time, realizing that everyone needed to consume salt, made salt taxes a major revenue source. Nomads spreading westward were known to carry salt. Egyptian art from as long ago as 1450 B.C. records salt-making.
