Rock salt is another name for Halite or sodium chloride (NaCl). In India, it is usually found in the Himalayan region where it is known as the Himalayan crystal salt or Himalayan salt. It is also known as Sendha Namak in Hindi and Saindhava Lavana in Sanskrit. Rock salt is usually obtained from salt mines by the process of dry or solution mining. Pure rock salt is usually colourless or white although its colours may vary from light blue, dark blue, purple to pink, orange, red, yellow or grey depending on the type and amount of impurities present it. The upside of Himalayan salt is that It occurs naturally and therefore is chemical free unlike the other table and common salts. In fact,  according to Ayurveda, rock salt is the best among all the salts available to us.
