Most sore throats are caused by viral infections and clear up on their own within five to seven days. In the meantime, several home remedies can meaningfully reduce pain, swelling, and irritation while your body fights off the infection. Here’s what actually works and why.
Salt Water Gargle
A salt water gargle is one of the simplest and most effective sore throat remedies. Mix half a teaspoon of salt into one cup of warm water, gargle for 15 to 30 seconds, and spit it out. The salt draws excess fluid out of swollen throat tissue through osmosis, which temporarily reduces inflammation and pain. You can repeat this several times a day as needed.
The warm water also helps loosen mucus and flush irritants from the back of your throat. It won’t cure an infection, but for raw, swollen tissue, the relief is almost immediate.
Honey
Honey coats and soothes irritated throat tissue, and its thick consistency helps it cling to the area longer than other liquids. A large systematic review published in BMJ Evidence-Based Medicine found that honey performed about as well as the active ingredient in most over-the-counter cough suppressants for reducing cough frequency and severity. It’s a reasonable substitute if you’d rather skip the medicine aisle.
You can take honey straight by the spoonful, stir it into warm tea, or mix it with warm water and lemon. One important safety note: never give honey to a child under one year old. Honey can contain bacterial spores that an infant’s immature gut bacteria can’t neutralize, creating a risk of infant botulism. After age one, the risk drops to nearly zero.
Warm and Cold Drinks
Both warm and cold liquids soothe a sore throat, but they work through different mechanisms. Cold drinks and ice pops narrow blood vessels, which reduces swelling and numbs pain in the short term. Warm liquids like broth or tea open blood vessels, improve circulation to the area, and help relax tight throat muscles. Neither option is objectively better. Use whichever feels more comfortable, and if one makes your throat feel worse, switch to the other.
Staying well hydrated matters regardless of temperature. A dry throat intensifies soreness, and when you’re fighting an infection, your body needs extra fluids. Water, broth, diluted juice, and herbal teas all count. Avoid alcohol and very caffeinated drinks, which can dehydrate you.
Herbal Teas Worth Trying
Not all teas are equal when it comes to throat relief. Several have specific properties that go beyond simple hydration.
- Chamomile contains plant compounds that reduce inflammation and may inhibit bacteria. It’s also mildly sedating, which helps if a sore throat is keeping you up at night.
- Peppermint contains menthol, which numbs and cools irritated throat tissue on contact. Even breathing in the steam can open up congested airways.
- Ginger has natural anti-inflammatory compounds that reduce swelling and pain. Fresh ginger slices steeped in hot water work well, and you can add honey for extra coating.
- Licorice root has both anti-inflammatory and antiviral properties. It’s widely available as a bagged tea.
- Green tea is rich in plant compounds with antiviral and antioxidant effects that can reduce inflammation in the throat lining.
Drink these warm rather than scalding hot. Extremely hot liquids can further irritate already inflamed tissue.
Throat-Coating Remedies
Some herbs form a gel-like substance called mucilage when mixed with water. This mucilage physically coats the throat, creating a protective barrier over raw, irritated tissue. Marshmallow root is one of the best-studied options. A 2019 study found it offers quick relief for symptoms related to respiratory conditions by building a protective layer in the mouth and throat that reduces irritation and swelling.
Slippery elm works through the same mechanism. Its bark is rich in mucilage and has been used for centuries as a throat soother. You can find both marshmallow root and slippery elm as teas, lozenges, or powdered supplements that dissolve in warm water.
Humidity and Air Quality
Dry air pulls moisture from your throat’s mucous membranes, making soreness worse. This is especially common in winter when heating systems run constantly. A humidifier can help by keeping indoor humidity between 30% and 50%, which is the ideal range for comfort without encouraging mold growth. A simple hygrometer (available for a few dollars at most hardware stores) lets you monitor the level.
If you don’t have a humidifier, sitting in a steamy bathroom for 10 to 15 minutes works as a short-term substitute. You can also place a shallow bowl of water near a heat source to add some moisture to the air. Clean any humidifier regularly to prevent it from becoming a source of mold or bacteria.
Other Simple Measures
Sucking on ice chips or frozen fruit bars provides localized numbing without needing to drink a full beverage. Hard candies or lozenges (even non-medicated ones) stimulate saliva production, which keeps the throat moist and washes away irritants. Resting your voice also helps. Talking, whispering, and clearing your throat all create friction against inflamed tissue, so giving your vocal cords a break speeds recovery.
Elevating your head slightly while sleeping can prevent mucus from pooling at the back of your throat, which often triggers coughing and worsens irritation overnight. An extra pillow is usually enough.
Signs Your Sore Throat Needs Medical Attention
Home remedies work well for viral sore throats, which make up the majority of cases. But some sore throats are caused by strep bacteria and require antibiotics. Strep throat typically comes on suddenly with fever, severe pain when swallowing, and swollen lymph nodes in the front of the neck. You might see red, swollen tonsils, sometimes with white patches or streaks. Notably, strep throat usually does not come with a cough, runny nose, hoarseness, or red eyes. Those symptoms point toward a virus.
A rapid strep test or throat culture is the only way to confirm a bacterial infection. If you have a high fever, can’t swallow liquids, notice a rash alongside your sore throat, or your symptoms haven’t improved after seven days, it’s worth getting tested. In children over three, a negative rapid test is typically followed up with a throat culture to make sure strep isn’t missed.
