Rock Salt (Sendha Namak)


  • Rock salt (Sodium chloride) is the common name for the mineral ‘halite’ or ‘Land salt’. It is mined from deposits in the ground.
  • Rock salt crystals are larger, less refined, and more discolored than purified ‘table salt’. It can have impurities of gypsum (CaSO4) and sylvite (KCl) but it is very rare to find potassium sulfate as a mineral, although occasionally polyhalite (K2Ca2Mg(SO4)4.2H2O) is found associated with rock salt deposits.
  • It does not contain additives such as iodine or anti-caking agents commonly found in table salt.
  • The salt is sold in most grocery stores or health food stores in either edible/gourmet or inedible forms. The inedible form is not dangerous, however it does contain grit that would make it unpleasant to eat.
  • It is lower in sodium thus it is believed that it helps in checking the blood pressure.
  • Its best known use is to help make homemade ice cream in an electric or hand-crank machine. The salt lowers the freezing point of the ice, which causes it to melt. Melted ice water is much better at absorbing the heat from the ice cream mixture than ice cubes and this makes the ice cream freeze faster.
  • The edible form of rock salt can be used in the cooking and seasoning of the food.
  • The importance of this salt can be realized from the fact it is used in number of Ayurvedic medicines.
  • In India, it is used mainly during 'fasts' and known as ‘Sendha Namak’.

RespectedDr. Razda,
I am trying different salts as chemical reactions to counteract with my allergenes- smoke, scents, perfumes, smells etc. which causes me dullness, if in contact for laong my stomach get upset.By using salt+ lemon + water for abut three months I have found good results. Earlier after coming into contact with these allergens I got affected within about 45 minutes. Now that time has increased to about 200 minutes and effect is also of lower degree.
use of black salt has caused slightly running nose, and cought (mucus) for few days. On 180411 I had started Sendha Namak also it has also caused a bit of watery nose.
Kindly guide me about chemical reactions of salt and other items which can be used as chemical reactions to overcome allergies.
I have also started Aleovera.
