From the Guidelines

Salt water gargles are a recommended remedy for relieving a sore, swollen throat, as they can help reduce swelling and pain through osmosis, loosen mucus, and soothe irritated tissues. To use this remedy effectively, mix 1/4 to 1/2 teaspoon of table salt in 8 ounces (1 cup) of warm water until dissolved. Gargle with this solution for 30 seconds, then spit it out. Repeat this process 3-4 times daily, especially after meals and before bed. Although the provided evidence does not directly address the effectiveness of salt water gargles for a sore throat, the principles of symptom management discussed in the guidelines 1 support the use of supportive therapies that can improve quality of life, such as salt water gargles. The warm temperature of the water additionally soothes irritated tissues, and this remedy is most effective for mild to moderate throat pain when used consistently. If your sore throat persists beyond 5-7 days, is accompanied by high fever, difficulty breathing or swallowing, or severe pain, you should see a healthcare provider as these symptoms may indicate a more serious condition requiring medical treatment.

The guidelines provided focus on the management of acute sore throat and viral rhinosinusitis, emphasizing the importance of symptom relief and the limited role of antibiotics in these conditions 1. While they do not specifically mention salt water gargles, they discuss the use of supportive therapies like nasal saline, which has a similar mechanism of action in providing symptom relief. The use of analgesics, anti-inflammatory agents, and other palliative medications is also recommended for symptom management, highlighting the importance of a multifaceted approach to relieving throat discomfort.

In the context of managing a sore, swollen throat, it is essential to prioritize remedies that are safe, effective, and have a low risk of adverse reactions. Salt water gargles fit this criteria, and when combined with other supportive measures like staying hydrated, resting, and using analgesics as needed, they can play a significant role in alleviating throat discomfort. As always, if symptoms worsen or do not improve with self-care, medical evaluation is necessary to rule out more serious conditions that may require specific treatment, as indicated by the guidelines 1.

  • While salt water gargles are often recommended as a home remedy for sore throats, there is no scientific evidence provided in the studies to support their effectiveness in relieving symptoms.

Treatment of Pharyngitis

  • The studies recommend the use of antibiotics, such as penicillin and amoxicillin, for the treatment of bacterial pharyngitis 2, 3, 5, 6.
