Rock Salt (Sendha Namak) Benefits & Uses

Rock Salt (also called Sendha Namak in Hindi and Saindhava Lavana in Sanskrit) is naturally occurring mineral form and isometric crystals of Sodium Chloride. Its color can vary according to a variety of impurities present in it.

Ayurveda recommends the regular use of Sendha Namak in your foods. You should not use other types of salts in your cooking.

Ayurveda divides Sendha Namak into two main varieties including White Sendha Namak and Pink or Red Sendha Namak.

  1. White Sendha Namak (also called White Rock Salt).
  2. Pink or Red Sendha Namak (also called Himalayan Pink Salt).

Both are good for health and used in ayurvedic medicine. You can use these varieties. Sometimes, we doubt the white variety of rock salt, which might be adulterated with sea salt. So, we always prefer Himalayan Pink Salt.

All other forms of rock salt including dark or light blue, purple, gray, dark black, orange and yellow are not considered the best form of Sendha Namak.

Black salt or Kala Namak is also a type of rock salt, which contains sulfur content in addition to sodium chloride. According to ayurveda, it is second best salt for using in food after white Sendha Namak and pink Sendha Namak.

  1. I am Shashi Prakash Bhardwaj from India. I am 57 year old. I was hypertensive for 20 years and used to take 50mg of Losar H daily in the morning. I discontinued intake of regular salt (Tata Salt) as it is pure Sodium Chloride and started cooking with sendha namak. I used to consume regular salt only when I eat outside home.

    I regularly consumed it regularly then slowly my medicine reduced to half and then quarter. Finally after 4 years doctor stopped my hypertensive medicine. I still continue to take it regularly and my BP remains 80/130.
