A sore, scratchy, or burning throat can make every swallow painful and every word an effort. Home remedies for throat infection have been passed down through generations, but not all of them are equally effective. Knowing which remedies are supported by evidence can help you find relief faster and avoid wasting time on approaches that do not work.
The good news is that most throat infections are caused by viruses and resolve on their own within five to seven days. During that time, home remedies for throat infection can significantly reduce pain and discomfort. According to the Mayo Clinic, viral pharyngitis accounts for 70 to 95 percent of sore throats in adults. The remaining cases are caused by bacteria, most commonly Group A Streptococcus, which requires antibiotic treatment. Regardless of the cause, the home remedies in this guide can provide meaningful symptom relief.
Saltwater Gargle
Gargling with warm saltwater is one of the most time-tested and well-supported home remedies for throat infections. The practice works through several mechanisms: the hypertonic salt solution draws excess fluid from swollen throat tissues (osmosis), reduces inflammation, loosens mucus, and creates an environment that is less hospitable to bacteria.
To prepare an effective saltwater gargle, dissolve one-half to three-quarters of a teaspoon of table salt in eight ounces of warm water. Gargle for 15 to 30 seconds, spit, and repeat until the glass is empty. The Cleveland Clinic recommends gargling every one to two hours for maximum benefit during acute throat pain.
A randomized controlled trial published in the American Journal of Preventive Medicine found that regular saltwater gargling during cold season reduced the incidence of upper respiratory infections by 40 percent compared to controls. The study suggests that saltwater gargling may have both therapeutic and preventive benefits.
Honey
Honey is far more than a folk remedy for sore throats. Multiple studies have validated its effectiveness as a throat soother and cough suppressant. A systematic review published in BMJ Evidence-Based Medicine concluded that honey is superior to usual care for improving symptoms of upper respiratory tract infections, including sore throat.
The therapeutic properties of honey include its thick, viscous consistency that coats and protects irritated throat tissues; natural antimicrobial compounds including hydrogen peroxide, methylglyoxal (particularly in Manuka honey), and defensin-1; anti-inflammatory effects that reduce swelling; and antioxidant properties that support tissue healing.
For throat infection relief, take one to two tablespoons of honey directly or mix it into warm water, tea, or lemon water. A study published in Pediatrics found that a single dose of honey before bedtime was more effective than dextromethorphan (a common cough suppressant) at reducing nighttime cough and improving sleep in children with upper respiratory infections.
Important safety note: never give honey to children under 12 months of age due to the risk of infant botulism. For older children and adults, honey is considered safe and effective.
Warm and Cold Liquids
Staying hydrated is essential during any throat infection, and the temperature of your beverages can provide additional therapeutic benefit:
Warm liquids. Warm tea, broth, and warm water with lemon increase blood flow to the throat, which promotes healing and helps soothe irritated tissues. Herbal teas offer additional benefits depending on the variety:
- Chamomile tea has anti-inflammatory, antioxidant, and astringent properties. Research in Molecular Medicine Reports suggests it may help reduce throat inflammation.
- Peppermint tea contains menthol, which has a mild anesthetic effect and can temporarily numb throat pain. It also acts as a natural decongestant.
- Ginger tea has anti-inflammatory properties and may help reduce throat swelling. A study in the Journal of Ethnopharmacology found that ginger extract has activity against several respiratory pathogens.
- Slippery elm tea contains mucilage, a gel-like substance that coats and soothes the throat. It has been used in traditional medicine for centuries and is recognized by the NIH as a demulcent.
- Licorice root tea has been shown in some studies to reduce sore throat severity. A study in the journal Anesthesia and Analgesia found that licorice root gargle reduced the incidence and severity of sore throat after surgery.
Cold liquids and frozen foods. Cold water, ice chips, and popsicles can numb throat pain and reduce inflammation, much like applying ice to a sprained ankle. Some people find cold more soothing than warmth, particularly when the throat is severely inflamed. Frozen fruit bars and smoothies provide both cold relief and nutrition.
Humidification and Steam
Dry air is an enemy of inflamed throat tissue. The NIH recommends using a humidifier to add moisture to indoor air during throat infections, particularly during winter when heating systems dry out indoor environments. Aim for a humidity level of 40 to 60 percent.
Steam inhalation offers more direct relief. Breathing in warm, moist air can soothe irritated throat and nasal passages, loosen mucus, and reduce the sensation of dryness. Methods include taking a hot shower and breathing in the steam, leaning over a bowl of hot water with a towel draped over your head, or using a personal steam inhaler. Adding a few drops of eucalyptus or menthol oil to the water may enhance the soothing effect, though this should not be done with young children due to the risk of airway irritation.
Anti-Inflammatory Foods and Supplements
Certain foods and supplements may support your body’s ability to fight infection and reduce throat inflammation:
Garlic. Fresh garlic contains allicin, a compound with antimicrobial and anti-inflammatory properties. Research published in Advances in Therapy found that a garlic supplement containing allicin reduced the frequency and duration of colds. While eating raw garlic may be uncomfortable with a sore throat, adding it to warm broth or soup provides a gentler delivery method.
Turmeric. The active compound curcumin has potent anti-inflammatory effects. Adding turmeric to warm milk (a traditional remedy known as “golden milk”) or to soups provides both the anti-inflammatory benefit and the soothing effect of warm liquids. A pinch of black pepper enhances curcumin absorption by up to 2,000 percent according to research published in PubMed.
Vitamin C. While not a cure, adequate vitamin C intake supports immune function. The NIH notes that vitamin C deficiency impairs immune response, and supplementation in people with adequate levels provides modest benefits for cold duration.
Zinc lozenges. When dissolved slowly in the mouth, zinc lozenges deliver the mineral directly to throat tissues. A meta-analysis in the Open Forum Infectious Diseases concluded that zinc lozenges can significantly reduce the duration of the common cold, including sore throat symptoms, when started within 24 hours of symptom onset.
Throat Coating and Soothing Techniques
Creating a protective barrier over irritated throat tissues can reduce pain and promote healing:
- Marshmallow root. Like slippery elm, marshmallow root contains mucilage that coats the throat. It is available as a tea, lozenge, or supplement. The NIH recognizes its traditional use as a demulcent for throat irritation.
- Baking soda gargle. Mixing one-quarter teaspoon of baking soda in eight ounces of warm water creates an alkaline solution that may help reduce throat acidity and kill bacteria. Some people alternate between saltwater and baking soda gargles throughout the day.
- Apple cider vinegar. One tablespoon of apple cider vinegar mixed into a glass of warm water can be used as a gargle. Its acidity may help break down mucus, though clinical evidence for this use is limited. Dilute it well to avoid irritating the throat further.
Rest and Environmental Optimization
The body heals most efficiently during rest, and creating an optimal recovery environment can accelerate the process. Sleep allows the immune system to function at peak capacity, with research showing that people who sleep fewer than seven hours per night are nearly three times more likely to develop a cold than those who sleep eight hours or more.
Additional environmental strategies include keeping the room at a comfortable temperature, avoiding secondhand smoke and other air pollutants, using an air purifier if available, and sleeping with your head slightly elevated to reduce post-nasal drip that can irritate the throat during the night.

When Home Remedies Are Not Enough
See a healthcare provider if you experience any of the following:
- Sore throat lasting more than seven days
- Fever above 101 degrees Fahrenheit lasting more than two days
- Difficulty breathing or swallowing
- Inability to open your mouth fully
- Blood in saliva or phlegm
- A lump in the neck
- Hoarseness lasting more than two weeks
- Severe pain on one side of the throat
- Drooling due to inability to swallow
- Rash accompanying the sore throat
These symptoms may indicate a bacterial infection requiring antibiotics, a peritonsillar abscess, epiglottitis, or other conditions that need medical treatment. Children who refuse to eat or drink due to throat pain should be evaluated to prevent dehydration.
Frequently Asked Questions
What is the fastest home remedy for a sore throat?
For immediate relief, a combination approach works best. Gargle with warm saltwater to reduce swelling, then take a tablespoon of honey to coat and soothe the throat, and sip warm tea throughout the day to maintain hydration and comfort. Over-the-counter throat sprays containing benzocaine or phenol can provide near-instant numbing. Most people notice meaningful improvement within one to two hours of starting this combined approach. For pain management, ibuprofen or acetaminophen provides systemic relief within 30 to 60 minutes.
Does drinking warm water help a throat infection?
Yes, warm water provides several benefits during a throat infection. It increases blood flow to the throat tissues, which promotes healing and helps deliver immune cells to the area. Warm water also helps thin mucus, making it easier to clear. Staying well-hydrated keeps the throat moist and prevents the drying that worsens irritation. Adding honey, lemon, or a pinch of salt to warm water enhances these benefits. However, avoid water that is too hot, as it can burn already-sensitive tissues.
Can a throat infection go away on its own?
Most throat infections caused by viruses resolve on their own within five to seven days without medical treatment. Home remedies can help manage symptoms during this period. However, bacterial throat infections, particularly strep throat, may worsen without antibiotic treatment and can lead to serious complications. If your sore throat is severe, accompanied by high fever, or not improving after a week, see a healthcare provider for evaluation. A simple rapid strep test can determine whether antibiotics are necessary.
Is it better to rest my voice with a throat infection?
Yes, vocal rest is beneficial during a throat infection. Speaking requires the vocal cords to vibrate, which generates additional friction and strain on already-inflamed tissues. Reducing the amount you talk allows the throat to heal more efficiently. If you must speak, use a normal voice rather than whispering. Contrary to what many people believe, whispering actually creates more tension in the vocal cords than normal speech and can worsen strain. Use written communication, text messages, or gestures when possible until the infection resolves.
Home remedies for throat infection can provide significant symptom relief and support your body’s natural healing process. While most sore throats respond well to these simple interventions, staying alert for warning signs that indicate a need for medical attention ensures that more serious conditions are caught and treated promptly. When in doubt about the nature of your throat infection, a visit to your healthcare provider can provide clarity and appropriate treatment.
