“Salt is essential to life in the right proportion. Saindhava rock salt comes from the open mines inland. It is considered the best of all salts as it is easy to digest, and does not cause water retention as readily as other types. It is classified as netrya and is beneficial to the eyes.” Ayurvedic Medicine by Sebastian Pole
Saindhava is high in minerals, cooling, sweet and easy to digest. As a muscle relaxant, Saindhava is applied in a warm bath.
