Types of Salt

Salt is indispensable to one's health, but an excess of salt or eating the wrong kind of salt also gives rise to health problems.

There are many types of salts. Some are mined from the salt deposits left by the dried up lakes and some are procured from the sea water. Some common types of salts are:

  • Table salt. This is the regular refined salt that has added chemicals that we consume daily in our food.
  • Kosher salt. This is a large-grained, irregularly shaped crystal salt mainly used for removing as much blood from meat as possible in order to comply with Jewish dietary laws.
  • Sea salt. Sea salt is produced from sea water.
  • Pickling salt. Pickling is a very fine salt, with no additives, that's used in brines used to pickle foods.
  • Celtic salt. Celtic salt is made by the process of the solar evaporation of water from the Celtic sea.
  • Seasoned salt. This refers to a variety of salts wherein herbs are added. For example, garlic salt, onion salt, and so forth.
  • Sendha namak (Rock salt). A large crystalline salt that's usually used for making ice cream in ice cream machines. Food grade rock salt is also available to use in regular cooking.
  • Kala namak (Black salt). This is a dark, reddish-black colored crystalline salt that turns a pinkish grey color when ground up. It has a distinct sulfurous odor and taste.

According to Ayurveda, Sendha namak or rock salt is the best kind of salt for eating. The next best is Kala namak or black salt.

This article will focus on the last two types of salts — rock salt and black salt.

Sendha Namak (Rock Salt)

Sendha namak is the Indian name for rock salt. It is a large-grained, coarse salt also called halite or land salt that's normally available in large bags in most grocery and health food stores. It dissolves readily in water.

  • Sendha namak is mined from underground deposits of dried up lakes. It is unrefined, non iodized and contains no additional anti-caking agents. It is white, pink, or blue in color.
  • This salt is lower in sodium than regular table salt and contains 94 trace minerals as opposed to just the three that are in common table salt. Since this salt is pure, it is used in religious fasts in India. It does not contain the toxic wastes that sea salt has from the polluted waters.
  • Sendha namak or rock salt is used in Ayurvedic medicines as it treats disorders arising from disturbances in the 3 doshas.
  • Rock salt benefits the heart, is good for diabetics, prevents osteoporosis, reduces depression and stress, prevents and treats muscle cramps, numbness and tingling sensations, regulates blood pressure, keeps the blood vessels flexible, maintains the correct acid-alkaline levels, helps in digestion, relieves a number of skin problems, benefits in relieving arthritic problems etc.
  • This salt is more cooling than sea salt and can be used in small quantities even when other salts have been prohibited.
  • In India, rock salt or sendha namak is used in making chutneys, raita (a variety of yogurts), chaats, snacks, and more.
  • It lowers the freezing point of water and when sprinkled on ice is used in ice cream making machines. Rock salt is also applied on roads to prevent ice formation on roads in winter and even on ice to make it soft for easy removal.
  • Rock salt is the best salt for consumption and replacing the common salt with sendha namak completely for those suffering with arthritis will offer them a lot of relief.
  • Sendha salt (commonly known as rock salt) is more beneficial than other edible salts for patients suffering from chronic kidney disease.

Kala Namak (Black Salt)

Black salt or Kala namak is a dark brown (almost black) colored crystalline salt that changes to a pinkish grey powder once it is ground up. It is also referred to as sanchal.

  • It has a sulfurous smell — much like boiled eggs, from the sulphur in it.
  • Kala namak is rich in iron and many other trace minerals and is cooling in nature.
  • The dark color is due to its iron content. This salt is obtained from the natural salt mines in Northern India and Pakistan.
  • Kala namak or black salt is used extensively in Ayurvedic medicine. It is also used as a condiment in Indian cooking. It's added to chaat, chutneys, and sprinkled on fruits and other Indian snacks before eating. It tastes great on cut vegetables, too.
  • Black salt is low in sodium. It is also much used in Ayurvedic medicine to treat health issues like indigestion, constipation, bloating, gas, flatulence and heartburn. It is also used to treat goiter and hysteria, poor vision, high blood pressure, anemia, and more. It ensures proper sodium/phosphorus balance.
  • Ayurvedic toothpastes also contain Kala namak as one of its ingredients.

      My son told me about a year ago that he had read regular salt was harmful to your health, and switched to sea salt. I'll have to send him this hub, as he may want to switch to rock salt. After reading this, I think I'll try rock salt as well. Voted up, useful and sharing.

      @Carol-thanks and good to know you appreciate the info. Thanks for the vote and shares.

      @Margaret-your son is right. The videos are unfortunately in Hindi, an Indian language and they have sensational info regarding the benefts of rock salt and black salt. Ayurveda emphasizes the useful of these healthy salts and not the normal table salt which it terms harmful to health.

      I hope your son finds this info useful. Thanks for the visit and sharing.

      @Shadaan-you are right. these salts have very useful health benefits.

      @MsDora- glad you liked the hub. Thanks for stopping by.

      Hi Rajan,

      I had no idea that rock salt was so beneficial for human consumption. I had (previous to reading this hub) only known of it for use in making ice cream and for use on roads during icing conditions. Will definitely consider purchasing some after reading this article. I always enjoy learning new things from you. Up votes and happy to share.

      Wow, rock salt looks pretty! It's interesting to learn the positive things about it, too. Thanks for sharing this with us.

      Rajan, I am preparing an article on calorie-free condiments, spices and herbs. I am not going into detail on my hub about any particular type, so I was wondering if you would mind if I put links to some of your spice and salt hubs? Or else just put a link to your page, with some of your hubs listed? You have so many that would be beneficial to anyone looking for more information on a particular type. Feel free to let me know what you think.

      Have a good weekend!

      Rajan Singh Jolly 4 years ago from From Mumbai, presently in Jalandhar,INDIA.

      moonlake, though all salt is harmful in excess, rock salt is the healthiest salt due to the nutrients it contains as opposed to the usual salt that has none.

      Thanks for the votes and sharing.

    • Suhail and my dog profile image

      Suhail Zubaid aka Clark Kent 3 years ago from Mississauga, ON

      Very informative hub Rajan.

      My experience from childhood was that after an hectic exercise or play session, you had to drink water with some salt mixed in it to make up for lost content of it in the body. However, in some books on hiking, I read the advice that after a sweaty hiking session, always drink water without taking any salt.

      Can you please shed some light on this matter as I am a bit confused?

      Just to let you know, since ages, I haven't taken salt with my water no matter how hectic an exercise I come from.

    • rajan jolly profile image

      Rajan Singh Jolly 3 years ago from From Mumbai, presently in Jalandhar,INDIA.

      Suhail, since sweat depletes the body of salts as well as water it would be prudent to include salt or electrolytes in water as this would enable the body to return to normal hydration faster. This is my thinking.

      Thanks for stopping by.

      Sendha Namak 3 years ago

      Doctor Shudh Sendha Namak - Rock salt is another name for the mineral halite which is commonly known as sodium chloride and has a chemical formula NaCl. It is commonly known as table salt or ‘sendha namak’ in India. It is mostly colorless or white though its color may vary from light blue, dark blue, purple to pink, red, orange, yellow or grey depending upon the amount and type of impurities present in it.

In the Indian subcontinent, it is found in the Himalayan region where it known as the Himalayan crystal salt.

      Rajan Singh Jolly 5 months ago from From Mumbai, presently in Jalandhar,INDIA.

      I do not think so. Ayurveda recommends Sendha namak and also till a few decades back no iodine was added to salt sold in India.
