Traditional Uses: Traditionally used since ancient times as a food preservative and seasoning, for wound cleansing and as a topical antiseptic, in salt therapy (halotherapy) for respiratory conditions, and as a base for preserving foods and promoting electrolyte balance in traditional diets.
Potential Benefits: May help maintain proper hydration, support electrolyte balance, provide trace minerals (magnesium, potassium, calcium) in small amounts, and support thyroid function (due to iodine content if iodized); salt inhalation (halotherapy) may provide mild respiratory relief.
Warnings: Avoid excessive intake (can cause hypertension, fluid retention, kidney damage, and increased cardiovascular risk); use cautiously in individuals with high blood pressure, kidney disease, heart failure, or on a sodium-restricted diet; limit to 2,300 mg of sodium per day (about 1 teaspoon of salt).
