Overview
Rock Salt is one of the herbs traditionally used in Ayurveda for heartburn & acid reflux. Saindhava (Rock Salt) is considered the best among all salts in Ayurveda. Unlike common salt (Samudra Lavana), it does not aggravate Pitta. It is recommended for daily use over sea salt. Found naturally in salt mines, especially in Sindh/Punjab region (hence Saindhava — from Sindhu). Contains trace minerals. Recommended as the salt of choice in Ayurvedic diet.
