Can Gargling With Vinegar Cure a Sore Throat?

No. Gargling with vinegar has not been established as a cure for a sore throat. Vinegar may irritate the throat, especially when concentrated. A warm salt-water gargle may temporarily soothe throat discomfort, but it does not cure every cause of a sore throat either. Vinegar is acidic and may affect microorganisms in laboratory settings, but that does not mean gargling vinegar treats the viruses, bacteria, inflammation, or other conditions that cause sore throats. It should not be used as a substitute for medical evaluation or treatment.

This article explains what vinegar gargling can and cannot do, why it may be uncomfortable, and when a sore throat needs medical attention.

What Can Help Sooth a Sore Throat

Warm salt-water gargling
Drinking fluids
Warm or cool beverages
Soft foods
Ice chips or suitable lozenges
Rest
Avoiding smoke and other irritants
Using a clean humidifier or cool-mist vaporizer

According to the Mayo Clinic, for adults and older children who can gargle safely, common guidance uses approximately ¼ to ½ teaspoon of salt in 4 to 8 ounces of warm water, followed by spitting it out rather than swallowing. Young children may not be able to gargle safely and may swallow the liquid or choke so use caution.

Vinegar Gargling Safety

Do not use vinegar if swallowing is already painful or difficult.
Do not give vinegar gargles to young children.
Do not use vinegar to treat a suspected strep infection.
Do not mix vinegar with other household products.
Keep vinegar away from the eyes.
