The Claim

Sodium chloride exhibits antiviral activity against multiple virus types, including coronaviruses, in laboratory settings, which may explain the mechanism underlying observed symptom improvements.

Source: Hypertonic saline nasal irrigation and gargling should be considered as a treatment option for COVID-19

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

Salt might help fight viruses like coronaviruses in lab tests, and this could be why people feel better when they use salt-based treatments.

See the scientific wording

Sodium chloride (salt) demonstrates antiviral activity against multiple virus types including coronaviruses in laboratory settings, potentially explaining the mechanism behind observed symptom improvements.

What the research says

1 study

  1. Study: Hypertonic saline nasal irrigation and gargling should be considered as a treatment option for COVID-19

    The study found that salt water can kill viruses like coronaviruses in lab tests and helps people feel better faster when used as a nasal rinse or gargle, which matches the claim about salt's antiviral effects.
