Traditionally considered the healthiest form of salt in ayurveda, rock salt pacifies all the three doshas. Rock salt is categorized by some ayurvedic healers as a Sattvic food, helping to nurture the spirit. It contributes the salty taste and is a cooling spice. In ayurvedic medicine, rock salt is used as a laxative and a digestive. It is an ingredient in the Herbal Di-Gest formulation from Maharishi Ayurveda.
It is also an appetizer, especially when a pinch of it is eaten with a slice of fresh ginger before a main meal. It gets the salivary and digestive juices flowing. You can add a pinch of rock salt to digestive lassi along with some crushed mint leaves, some shredded ginger and powdered dry-roasted cumin for a refreshing lunchtime beverage. You can also add it instead of common salt to foods such as Kichari and vegetables.
