# Saindhava Lavana

> Saindhava Lavana is a salt or alkali preparation used in Ayurveda. An absence here means we could not identify the source, not that no work exists.

## Names and identification

| Language | Name |
|----------|------|
| English | [Saindhava Lavana](/herb/saindhava-lavana/) Rock Salt |

## Key Phytochemical Constituents

- Sodium chloride (NaCl) - 97-99%
- Up to 84 trace minerals and elements
- [Potassium](/glossary/compounds-o-q/#potassium), [magnesium](/glossary/compounds-l-o/#magnesium), calcium
- Iron (responsible for pink color in some varieties)
- [Manganese](/glossary/compounds-l-o/#manganese), zinc, chromium
- Sulfate, bicarbonate
- [Iodine](/glossary/compounds-g-l/#iodine) (trace, variable)
- [Selenium](/glossary/compounds-q-t/#selenium), copper, fluoride (trace)

## How does it work?

- Digestive stimulation: Stimulates salivary amylase and gastric acid secretion; mineral content activates digestive [enzymes](/glossary/compounds-d-g/#enzymes) and promotes bile flow without causing inflammatory heat
- Electrolyte homeostasis: Balanced mineral profile (Na, K, Mg, Ca) supports cellular osmotic balance, nerve impulse transmission, and muscle contraction without pure sodium overload
- Tridosha balance: Unique cooling virya among salts prevents Pitta aggravation; slight sweetness and unctuousness pacify Vata; light quality prevents Kapha accumulation
- Cardiac support: Balanced mineral profile and lower pure sodium concentration per weight compared to refined salt may support better cardiovascular function

## Which traditional uses are supported by research?

- Agni Deepana (digestive stimulant): Validated by evidence showing rock salt stimulates salivary and gastric enzyme production and bile secretion without inflammatory side effects
- Netra Hita (beneficial for eyes): Traditional eye wash preparations with Saindhava have [antimicrobial](/reference/antimicrobial/) basis; trace minerals support ocular surface health
- Hridya (cardiotonic): Balanced mineral profile and lower sodium-per-weight ratio compared to refined salt provide modest cardiovascular advantage, partially validating the classical claim

## What do recent clinical trials show?



*3 further claims previously listed here could not be traced to a published paper and have been removed. An absence here means we could not identify the source, not that no work exists.*

## Recent safety updates

- Lower iodine content than iodized table salt; populations relying solely on rock salt may need iodine supplementation to prevent thyroid disorders
- Daily intake should be moderated (less than 5-6 g/day); excessive salt intake from any source increases hypertension risk
- Pink Himalayan salt health claims are often exaggerated in marketing; trace mineral amounts are too small for significant nutritional impact at normal consumption levels
- Purity varies by mine source; some commercial products may be contaminated with microplastics or industrial pollutants
