Rock Salt (Saindhava Lavana) is mined from the Himalayan range. This is an unrefined salt, naturally pink in colour. No additives are added to this salt. Ayurvedic Pharmaceutics, Rasashastra, considers saindhava lavana as the best of salt.
It can be used as a healthy substitute of common salt as it is rich in minerals and does not pose health problems like high blood pressure, puffiness in the body or eyes.
