Coarse salt can stimulate and promote the secretion of sebaceous glands, which helps to discharge the aging matter in the body and remove the dead skin layer on the surface, thus renewing the skin.

1, coarse salt has the role of sweating, it can discharge the body's waste and excess water, promote skin metabolism, but also soften the dirt, supplemental salt and minerals;

2, used to clean wounds can prevent infection;

3, sprinkled on food can be a short-term preservation of food can be used to pickle food can also be prevented from deterioration.

Crude salt is seawater or salt wells, salt ponds, salt springs in the brine by frying and sunshine into the crystals, that is, natural salt, is unprocessed large-grained salt, the main component of sodium chloride, but because of the presence of magnesium chloride and other impurities, in the air is more susceptible to deliquescence, and therefore should pay attention to the humidity when stored.

Expanded Information:

Salts are categorized into single and combined salts; single salts are categorized into normal, acidic, and alkaline salts; and combined salts are categorized into complex and complex salts.

Acid salts contain hydrogen ions in addition to metal ions and acid ions, and alkali salts contain hydroxide ions in addition to metal ions and acid ions, compound salts dissolved in water can generate the same ions as the original salt salt of the salt; complex salts dissolved in water can be generated with the original salt is not the same as the complex salt-complex ions.

Usually, insoluble salts are solid under standard conditions, but there are exceptions, such as molten salts and ionic liquids. Solutions of soluble salts and molten salts have electrical conductivity and therefore act as electrolytes. Many different salts are found in the cytoplasm of cells, blood, urine and mineral water.
