Seven Natural Remedies That May Help Soothe a Sore Throat

A sore throat is one of the most common discomforts people experience, whether from seasonal challenges, dry air, voice strain, or general immune stress. While a sore throat often resolves on its own within a few days, the discomfort in the meantime can be significant. Many people prefer to try natural approaches for comfort alongside any medical care their healthcare provider recommends.

These seven remedies have varying degrees of research support and a long history of traditional use. They are generally considered safe for most adults, though it is important to consult your healthcare provider if symptoms are severe, persistent, or accompanied by high fever.

1. Honey

Honey is perhaps the most well-studied natural remedy for throat comfort. A systematic review published in BMJ Evidence-Based Medicine found that honey was associated with improvements in sore throat symptoms, particularly when compared to usual care alone. Honey's thick, viscous consistency coats and soothes irritated throat tissue, and it contains naturally occurring compounds with antioxidant properties.

How to use it: Stir one to two tablespoons of raw, unprocessed honey into warm (not hot) water or herbal tea. Sip slowly, allowing the honey to coat the throat. Repeat two to three times daily as needed.

Important note: Honey should never be given to children under one year of age due to the risk of botulism.

2. Saltwater Gargle

Gargling with warm saltwater is one of the oldest and most widely recommended remedies for sore throat discomfort. Research published in the American Journal of Preventive Medicine found that regular saltwater gargling was associated with reduced frequency and severity of upper respiratory symptoms. The salt may help draw excess fluid from inflamed throat tissue, potentially reducing swelling and discomfort.

How to use it: Dissolve one-quarter to one-half teaspoon of table salt in eight ounces of warm water. Gargle for 15 to 30 seconds, then spit out the solution. Repeat three to four times daily. The relief is temporary but can be significant.

3. Ginger Tea

Fresh ginger root contains gingerols and shogaols, bioactive compounds that research suggests may have anti-inflammatory and antioxidant properties. A study in the journal Phytomedicine found that ginger consumption was associated with reductions in inflammatory markers. Additionally, ginger tea's warmth provides a soothing sensation for irritated throat tissue.

How to use it: Slice one to two inches of fresh ginger root into thin pieces. Steep in boiling water for 10 to 15 minutes. Strain and add honey and lemon to taste. Drink two to three cups daily.

Pro tip: For a stronger preparation, grate the ginger instead of slicing to release more of the bioactive compounds.

4. Marshmallow Root

Marshmallow root (Althaea officinalis) contains mucilage, a gel-like substance that becomes slippery when mixed with water. This mucilage may help coat and soothe irritated throat tissue. While clinical research on marshmallow root for sore throat specifically is limited, its use for throat comfort dates back thousands of years in European herbal traditions, and preliminary studies support its mucilaginous properties.

How to use it: Marshmallow root tea is widely available in tea bags from brands like Traditional Medicinals. Steep one tea bag in hot water for 10 to 15 minutes (longer steeping releases more mucilage). Marshmallow root lozenges are also available. Drink or use two to three times daily.

5. Apple Cider Vinegar

Apple cider vinegar (ACV) has a long history of use in folk medicine for throat discomfort. While scientific research on ACV for sore throats specifically is limited, its acidic nature may help create an environment less favorable for certain microbes. Some people report that diluted ACV gargling provides subjective relief.

How to use it: Mix one tablespoon of apple cider vinegar with eight ounces of warm water. Gargle for 15 seconds and spit. You can also add the same mixture to warm water with honey as a sipping tea. Use one to two times daily.

Caution: Never gargle or drink undiluted apple cider vinegar, as the acidity can irritate throat tissue and damage tooth enamel. Always dilute thoroughly.

6. Licorice Root

Licorice root (Glycyrrhiza glabra) has been used in Traditional Chinese Medicine and Ayurveda for centuries for throat comfort. Research published in the journal Anesthesia and Analgesia found that licorice root gargling before certain procedures was associated with reduced throat discomfort afterward. The active compound glycyrrhizin may have soothing and anti-inflammatory properties.

How to use it: Steep licorice root tea (available in tea bags) for five to ten minutes. Sip slowly, two to three cups per day. Licorice root lozenges are another convenient option.

Important caution: Licorice root can interact with certain medications and may affect blood pressure and potassium levels with prolonged or excessive use. Individuals with high blood pressure, heart conditions, or kidney issues should avoid licorice root or use DGL (deglycyrrhizinated licorice) forms. Consult your healthcare provider if you take medications.

7. Slippery Elm

Slippery elm (Ulmus rubra) inner bark, like marshmallow root, contains mucilage that forms a soothing gel when mixed with water. This gel is thought to coat and comfort irritated throat tissue. Slippery elm has been used by Native American peoples for centuries for throat and digestive comfort.

How to use it: Slippery elm is available as lozenges, powdered bark (mix one tablespoon with hot water to make a thick tea), or in pre-made tea blends. Throat Coat tea by Traditional Medicinals combines slippery elm with licorice root and marshmallow root. Use two to three times daily as needed.

Supportive Practices

Beyond specific remedies, several supportive practices can help ease sore throat discomfort. Stay well hydrated with warm fluids (water, herbal teas, broth). Use a humidifier to add moisture to dry indoor air. Rest your voice when possible. Avoid irritants like smoke and very dry air. Suck on ice chips or popsicles for temporary numbing relief.

When to See a Healthcare Provider

Natural remedies are appropriate for mild sore throats that accompany common seasonal challenges. However, seek medical attention if your sore throat is severe or worsening after several days, it is accompanied by a high fever (above 101 degrees Fahrenheit), you have difficulty swallowing or breathing, you notice white patches on your tonsils, or you experience a stiff neck along with throat discomfort.

Final Thoughts

While a sore throat is usually a temporary inconvenience, having a toolkit of natural remedies can provide meaningful comfort while your body recovers. These seven options are accessible, affordable, and backed by varying degrees of research and traditional use. Choose the remedies that appeal to you, use them consistently, and do not hesitate to consult your healthcare provider if symptoms are concerning or persistent.
