What to know before use
For a gargle, dissolve half a teaspoon in a cup of warm water, gargle and spit — never swallow. Two or three times a day is enough. A sore throat with high fever, difficulty swallowing or breathing, or one lasting beyond a week needs a doctor.
Important cautions
As a gargle in warm water it is one of the safest home measures there is. As a food, it is salt, and everything that applies to salt intake applies here — despite the healthier reputation.
Who should avoid it
- People on a sodium-restricted diet
- Anyone with high blood pressure, heart failure or kidney disease, beyond ordinary dietary amounts
- People with fluid retention
Medicine interactions
- High salt intake can work against blood pressure medicines and diuretics
PregnancyOrdinary dietary use is fine. Gargling is safe. Keep total salt intake moderate, particularly if you have raised blood pressure in pregnancy.
ChildrenGargling suits children old enough to spit reliably — usually around six years and up. Never let a child swallow salt water in quantity, as this is genuinely dangerous.
Quality and buying guidance
Crystals should be dry, clean and pale pink to grey. Note that rock salt is usually not iodised, so it should not fully replace iodised salt in the diet unless a clinician advises it. Store dry and airtight.
What does the evidence say?
This is primarily an established food with a long record of ordinary dietary use; nutritional information is better documented than medicinal claims.
