Sendha Namak (Rock Salt)- Uses, Benefits and Side Effects

Sendha Namaka

When saltwater from a sea or lake evaporates, leaving behind colored sodium chloride crystals, sendha namak is created. It is also known as rock salt, halite, or saindhava lavana. Although Himalayan pink salt is one of the most well-known forms of rock salt, there are several more. Sendha namak is great for keeping your skin and hair healthy. 

Sendha namak is beneficial to one’s health since it lowers nail yellowing, relieves stress, battles respiratory ailments, digestive issues, purifies the air, boosts metabolism, and treats sinusitis. 

Sendha Namak can come in a variety of colors, including grey, yellow, orange, red, pink, dark blue, and light blue, depending on the impurities present. Borates, halides, and sulfides are common companions. Sendha Namak, also known as halites, may be found in almost every country. The one discovered in France appeared to be filled with purplish fibrous vein filling. 

Sendha Namak crystallizes swiftly in rapidly evaporating lakes, resulting in modern artifacts with halite encrustations or coatings.

Although there are no special medical benefits to pink salt, the human body requires salt in its diet for a variety of reasons. For example, preventing dehydration is not a major concern for the average westerner because food and water are plentiful, and we are exceedingly unlikely to die of thirst in our daily lives.

How is Sendha Namak made?

Sendha namak is, without a doubt, India’s purest rock salt. Because it is not chemically treated like table salt and lacks iodine, it is only offered in limited quantities and is highly expensive.

Furthermore, table salt is ground into a fine powder, whereas sendha namak has a granular texture, consisting of large, rough crystals with a milder saline flavor. 

Sendha Namak is made from salt domes found in the United States, Pakistan, the United Kingdom, India, Romania, the Netherlands, Spain, Germany, and France. They are found in large beds of evaporated sedimentary minerals that form when confined seas, playas, lakes, and other bodies of water dry up. 

It is generated by the evaporation of dissolved sodium and chloride ions in salty water (such as seawater). Dry lake beds, places once covered by the sea, inland peripheral seas, enclosed bays, and other locations are common. Salt piles form and are buried in regions where there was once an ocean. 

Salt, which is light in weight, tends to rise, whereas hard rocks and other ores, which are heavy, tend to sink. The salt beds “punched up” through the deposits to form dome-like structures as a result of this.

Rock Salt Vs. Normal Salt

Salt is an essential component of our diet that provides flavor to food, but too much of it can lead to a variety of health issues, including high blood pressure, obesity, inflammation, and more.

Though you should limit the amount of salt you consume each day, you should also consider which type of salt is best. Although most of us use table salt daily, many people believe that rock salt is a healthier alternative.

  • Table salt is a white or colorless powder that we use to season our food. Rock salt, on the other hand, has a pinkish hue and is frequently found in crystals. It is the mineral form of sodium chloride and is also known as halite. Table salt is refined to remove contaminants and is treated with additions and chemicals such as anti-caking agents.
  • On the other hand, rock salt does not go through this process. Although, both salts have a nutritional value that is more or less comparable before the ordinary salt is processed further.
  • When this transpires, the majority of the salt’s naturally occurring minerals are eliminated. Furthermore, natural salt is not quite white, but common salt gets too white due to chemical processing. 
  • This may fulfill our desire for purity in everything white, but the fact is that this is precisely what causes us suffering. Not to mention the fact that table salt is made by heating a flaky residue of crude oil to a high temperature of 1200 degrees Fahrenheit, where it loses its minerals as a result of the heat. 
  • To make it more appealing, several fake manufacturers may add synthetic compounds and iodine. Plus, preservatives like aluminum hydroxide (which can injure the brain over time) and anti-caking compounds like sodium aluminosilicate or magnesium carbonate (which prevent clumping) weaken it even more
  • Rock salt, on the other hand, is made from the evaporation of seawater or water from saltwater lakes and is not as processed as table salt.

Nutritional Value of Sendha Namak

The unprocessed variety, i.e. rock salt, has more minerals than table salt since calcium, potassium, and other minerals are lost during the refining process. 

Table salt, on the other hand, contains more iodine than rock salt, which helps to avoid goiter, a disease caused by a lack of iodine.

Sodium chloride is the most common constituent, accounting for up to 98 percent of the total. It has a lot of valuable minerals and elements in it.

Iodine, Lithium, Magnesium, Phosphorus, Potassium, Chromium, Manganese, Iron, Zinc, Strontium, and other elements are also present. The iodine content of table salt is higher than that of rock salt. 

If you’ve been told to eat a low-iodine diet, rock salt is a preferable choice. Iodine is found in raw milk, cheese, yogurt, potatoes, seafood, prunes, eggs, and other foods. 

These essential components help the body perform a variety of tasks, including increasing metabolism, maintaining electrolyte balance, ensuring regular blood circulation, strengthening bones and muscles, and ensuring smooth nerve signaling between organs and tissues. This ensures optimum health and protects against a variety of illnesses and deficient conditions.

Uses of Sendha Namak

1. It is used for making salt lamps:- A light bulb is placed inside big chunks of pink Himalayan salt to create salt lamps. They believe the lamps can improve mood, sleep, allergies, asthmatic patients’ breathing, and purify the air, among other things. 

2. It is commonly used as a gritting salt for ice and, to a lesser extent, snow management in both home and municipal settings. It can help prevent snow from settling, but it’s best used after the snow has been plowed to keep walks, roads, driveways, and steps from icing. It operates by producing brine, which is a salt-water solution. This has a lower freezing point than regular water, thus adding salt over ice, whether white or rock salt, can melt it.

3. It can also be used as a powerful weed killer. When applied in tiny amounts, sodium chloride is perhaps the most environmentally friendly chemical weed killer available.
