Lavana rasa or the salty taste is made from the water and fire elements.
Lavana rasa is balancing for Vata dosha but aggravating for Pitta and Kapha. Salt is renowned for stimulating the digestion. If it is used wisely it is a medicine but when taken in excess it becomes a poison.
The Ayurvedic properties are: Rasa (taste): salty Virya (potency): heating apart from saindhava which is cooling Vipaka (post digestive effect): sweet Guna (qualities): heavy and wet Dosha: increases Pitta and Kapha, Balancing for Vata
(The Ayurvedic properties vary according to the different type of salt)
Salt aids digestion, increasing the absorption of nutrients from our food. The taste works directly on the taste receptors and clarifies the sense of taste. Higher dose can work as a laxative or emetic.
In the yogic practice of sankharpraksalana utilises the osmotic properties of salt to clear toxins out of the mucous membrane prior to purgation (Swami Satyananda).
Different types of salt
Table salt the kind that is often used for commercial cooking, is highly processed using various chemicals and is the least nutritious form of salt. It also contains a very high sodium concentration, which contributes to high blood pressure, kidney disease, oedema, inflammation, amongst other things. For these reasons, it is not recommended to consume table salt.
Sea salt is processed by evaporation or desalination. Evaporation is a natural process whereby water is simply evaporated from sea water to leave the salt. Sea salt is higher in minerals than table salt. For this reason it is considered to be healthier for us. Always choose a sea salt that is naturally harvested.
Rock salt such as pink Himalayan rock salt, is mined from rocks. Pink Himalayan rock salt is even higher in minerals, which is what gives it it’s pretty pink colouring. Rock salt is called saindhava lavana and this is considered the best among all salts.
Saindhava is of two varieties 1. Shweta saindhava - white in colour 2. Rakta saindhava - red in colour
