Saltwater gargles, honey, ice chips, and warm liquids all have clinical evidence behind them as sore-throat soothers, and most work by reducing inflammation, coating irritated tissue, or both. No single home remedy cures a sore throat, since the underlying cause is usually a virus that has to run its course, but several can meaningfully dial down the pain while your body does the real work. The trick is knowing which remedies have genuine support, which are harmless but unproven, and which can actually make things worse.
Saltwater Gargle
A warm saltwater gargle is probably the oldest sore-throat remedy in the world, and it holds up surprisingly well under scrutiny. In a randomized trial of patients with sore throats after surgery, those who gargled with warm saline had significantly lower pain scores at 12, 18, and 24 hours compared with a control group that did not gargle.1Journal of Research Development in Nursing and Midwifery. Effect of Warm Saline Solution Gargle on Sore Throat after Extubation in Open Heart Surgery Patients: A Randomized Clinical Trial – Section: Abstract The researchers described it as a practical, simple, and cheap approach to pain relief.
The mechanism is straightforward. A mildly salty solution draws excess fluid out of swollen throat tissue through osmosis, temporarily reducing the puffiness that makes swallowing painful. The warmth itself can relax tense muscles in the throat and increase blood flow to the area, which may help your immune cells do their job faster. Half a teaspoon of table salt dissolved in a full glass of warm water, gargled for 15 to 30 seconds and then spit out, is the standard approach. You can repeat it several times a day without worrying about side effects, since you are not swallowing the salt.
Honey
Honey is one of the few home remedies that works on multiple fronts at once. Its thick, viscous consistency physically coats irritated throat tissue, forming a protective barrier that reduces the raw feeling you get every time you swallow. Beyond the coating effect, honey has both antimicrobial and anti-inflammatory properties that contribute to its effectiveness in managing viral and bacterial throat infections.2Indus Journal of Bioscience Research. Evaluating the Effect of Honey as a Natural Remedy for the Management of Sore Throat – Section: Results It also promotes hydration of the mucous membranes, which is exactly what dried-out, inflamed tissue needs.
You can eat honey straight off a spoon, stir it into warm tea, or mix it with warm water and a squeeze of lemon. The lemon adds a bit of vitamin C and can help break up the sensation of mucus in the back of the throat. Manuka honey and other specialty varieties are sometimes marketed as superior, but garden-variety honey from the grocery store has the same coating and soothing properties that matter most for a sore throat.
One critical safety point: honey should never be given to children under 12 months old. Honey is the only definitively identified food source of Clostridium botulinum spores, and infants lack the mature gut bacteria needed to prevent those spores from producing toxin.3PubMed Central. The hazards of honey: infantile botulism The CDC recommendation against feeding honey to infants younger than 12 months is based on substantial evidence linking honey consumption to infant botulism cases across the United States.4PubMed. Association between honey consumption and infant botulism For adults and older children, honey is perfectly safe and arguably the single best-supported home remedy for throat pain.
Ice Chips, Popsicles, and Cold Therapy
If warmth is not your thing, cold works too. A study comparing cold vapor inhalation, ice chip absorption, and a combination of the two found that all three cold-therapy groups had significantly lower sore-throat pain scores than a control group receiving no treatment.5ScienceDirect. The Effect of Cold Vapor and Ice Cube Absorption in the Early Postoperative Period on Sore Throat and Hoarseness Induced by Intubation – Section: FINDINGS There was no meaningful difference between the cold-therapy methods themselves, which suggests that the temperature is doing the heavy lifting rather than the delivery method.
Cold numbs nerve endings in the throat, temporarily blunting pain signals. It also constricts blood vessels in inflamed tissue, which can reduce swelling. Sucking on ice chips or eating a popsicle gives you this benefit while also keeping you hydrated. Frozen fruit bars, smoothies, and even plain ice water all count. Some people alternate between warm and cold remedies throughout the day, and there is nothing wrong with that approach. Use whichever temperature feels better to you at any given moment.
Licorice Root Gargle
Licorice root has a long history in traditional medicine, and at least one well-designed trial backs it up for sore throats specifically. In a randomized, double-blind study, patients who gargled with a licorice solution before surgery had a sore-throat rate of about 19% at 30 minutes afterward, compared with 36% in the sugar-water placebo group. At the 90-minute mark, the licorice group’s rate dropped to 10% versus 35% for placebo.6PubMed. A randomized, double-blind comparison of licorice versus sugar-water gargle for prevention of postoperative sore throat and postextubation coughing Those are large differences for a simple gargle.
Licorice root contains glycyrrhizin, a compound with anti-inflammatory and mucous-membrane-soothing properties. You can buy licorice root tea bags at most grocery stores and gargle with the cooled tea, or find licorice root powder and dissolve it in warm water. A word of caution, though: people with high blood pressure should be careful with licorice, because glycyrrhizin can cause the body to retain sodium and lose potassium when consumed in large amounts over time. Occasional gargling is unlikely to cause problems, since you spit most of it out, but daily consumption of licorice supplements or large quantities of real licorice candy is a different story.
Marshmallow Root and Slippery Elm
Both of these herbs belong to the “mucilage” family of remedies. They contain complex carbohydrates that form a gel-like coating when mixed with water, and that coating physically soothes and protects irritated mucous membranes in the throat and respiratory tract.7IntechOpen. Utilization of Medicinal Herbal Plants in the Management of Respiratory Conditions – Section: Herbal preparations for treating respiratory conditions Think of it as a natural version of what a cough drop tries to do, but in liquid form.
Marshmallow root tea is widely available in health-food stores and online. You steep it in cold or warm water and drink it slowly, letting the thick liquid linger on your throat. Slippery elm comes as a powder, lozenge, or tea. Both are generally well tolerated, though it is worth noting that one European clinical guideline found the evidence for herbal sore-throat treatments to be inconsistent overall.8Wiley Online Library. Guideline for the management of acute sore throat The coating effect is real and many people find relief from it, but controlled trials specifically on marshmallow root and slippery elm for sore throats are limited. They are safe enough that trying them costs you little beyond the price of the tea.
Menthol and Throat Lozenges
Menthol is the active ingredient in most throat lozenges and cough drops, and it works by a clever bit of sensory misdirection. Menthol activates a cold-sensing receptor in your throat’s nerve endings, which creates a cooling sensation even at room temperature.9International Journal of Aromatherapy. Menthol: A review of its thermoreceptor interactions and their therapeutic applications – Section: Therapeutic activity of menthol Your brain interprets that signal as relief from the burning, scratchy feeling of inflammation. The effect is temporary, lasting maybe 20 to 30 minutes per lozenge, but it can get you through a difficult afternoon at work or help you fall asleep.
The act of sucking on any lozenge also stimulates saliva production, which keeps the throat lubricated. Some lozenges add pectin or honey for an extra coating effect. Zinc lozenges deserve a separate mention: while zinc can inhibit the replication of respiratory viruses in laboratory settings,10PubMed Central. The effectiveness of high dose zinc acetate lozenges on various common cold symptoms: a meta-analysis – Section: Discussion a European guideline on acute sore throat specifically does not recommend zinc gluconate for sore-throat treatment.8Wiley Online Library. Guideline for the management of acute sore throat Zinc lozenges may help with the overall duration of a cold, but their effect on throat pain specifically is not well established. Standard menthol lozenges are a more reliable bet for targeted throat relief.
Chicken Soup
Your grandmother was not wrong. A lab study found that chicken soup significantly inhibited the movement of white blood cells called neutrophils in a concentration-dependent manner, suggesting a mild anti-inflammatory effect that could help reduce upper respiratory tract symptoms.11PubMed. Chicken soup inhibits neutrophil chemotaxis in vitro Neutrophils are part of the immune response that causes the inflammation and swelling you feel in your throat, so slowing their rush to the scene could theoretically ease symptoms without impairing your body’s ability to fight the infection.
That said, this was a laboratory study, not a clinical trial in actual sick people, so take the mechanism with a grain of salt (and maybe a grain of pepper). What is undeniable is that hot soup delivers warmth, liquid, salt, and calories all at once, and all four of those things help when you are sick. The steam from a hot bowl can also temporarily open congested nasal passages, which takes pressure off your throat if you have been mouth-breathing due to a stuffy nose. Broth-based soups of any kind offer similar benefits. The chicken itself is not magic, but it makes the soup taste good enough that you will actually eat it, which matters when your appetite has vanished.
Garlic
Garlic contains allicin, a compound with documented antibacterial, antifungal, and antiviral activity in lab settings.12PubMed. Antimicrobial properties of allicin from garlic This has led to a longstanding folk belief that eating raw garlic can help fight off colds and sore throats. However, a Cochrane review on garlic for the common cold found that the evidence base is thin. Laboratory evidence of antibacterial and antiviral properties exists, but robust clinical trial data showing that eating garlic actually shortens or prevents illness in humans is lacking.13PubMed Central. Garlic for the common cold – Section: Plain language summary
If you enjoy garlic and can tolerate it when your throat is raw, adding it to soups or warm dishes will not hurt and may offer marginal antimicrobial benefits. Chewing raw garlic cloves, which some wellness sites recommend, is hard to stomach when your throat is already irritated and can cause heartburn or nausea. It is not a frontline sore-throat remedy, but it is a reasonable ingredient in the hot meals and soups you should be eating anyway.
Why You Should Skip the Apple Cider Vinegar Gargle
Apple cider vinegar is one of the most commonly recommended “natural” sore-throat remedies on the internet, and it is one of the worst ideas. The logic usually goes that vinegar’s acidity kills bacteria. In reality, vinegar is acidic enough to damage the very tissue you are trying to heal. A case report documented severe corrosive esophageal ulcers in an adolescent who consumed a vinegar beverage daily, with multiple ulcers, mucosal hemorrhage, and denuded mucosa found throughout the esophagus.14PubMed Central. Corrosive Esophageal Injury due to a Commercial Vinegar Beverage in an Adolescent The researchers concluded that vinegar beverages should be considered corrosive agents.
Gargling with diluted apple cider vinegar is less risky than drinking it straight, but you are still swishing acid over inflamed, fragile mucous membranes. Even heavily diluted, it stings, and that sting is not “killing bacteria.” It is irritating tissue that is already struggling to repair itself. There are plenty of remedies on this list that work without the risk of chemical burns. Skip this one entirely.
Humidifiers and Steam
Dry air is an underappreciated aggravator of sore throats. Heated indoor air in winter, air conditioning in summer, and mouth-breathing from nasal congestion can all dry out throat tissue and make inflammation feel worse. A humidifier in your bedroom can help keep your mucous membranes hydrated overnight, which is when many people notice their sore throat is at its worst.
A Cochrane review on heated, humidified air for the common cold did not find strong evidence that it speeds recovery overall, and noted minor adverse events like nasal discomfort or irritation in some studies.15PubMed Central. Heated, humidified air for the common cold – Section: Main results The benefit for sore throats specifically is more about comfort than cure. If your throat feels worse in the morning after sleeping in a dry room, a cool-mist humidifier is a reasonable addition. Clean it regularly to prevent mold growth, which can introduce new irritants into the air.
Inhaling steam from a bowl of hot water with a towel over your head is a time-honored approach that achieves a similar effect in the short term. It can temporarily loosen mucus and soothe inflamed tissue. Just be careful not to burn yourself with water that is too hot, and keep kids away from the steam setup.
When to Reach for Over-the-Counter Pain Relievers
Home remedies are most useful for mild to moderate sore throats caused by common viral infections. But if the pain is sharp enough that you are struggling to eat, drink, or sleep, there is no reason to suffer through it with honey alone. A European clinical practice guideline for acute sore throat recommends ibuprofen or acetaminophen (paracetamol) for symptom relief.8Wiley Online Library. Guideline for the management of acute sore throat These are well-studied, inexpensive, and effective. Ibuprofen has the added advantage of reducing inflammation directly, while acetaminophen handles pain without the anti-inflammatory component.
You can use home remedies alongside over-the-counter pain relievers. A saltwater gargle in the morning, ibuprofen before lunch, honey in tea throughout the afternoon, and ice chips in the evening is a perfectly reasonable rotation. The goal is to keep the throat as comfortable as possible while your immune system resolves the infection. If your sore throat lasts more than a week, comes with a fever above about 101°F (38.3°C), produces visible white patches on the tonsils, or makes it very difficult to swallow liquids, see a doctor. Those symptoms can point to strep throat or another bacterial infection that may need antibiotics.
Remedies for Children
Most of the remedies discussed here work for older children too, with some important adjustments. Saltwater gargles are great once a child is old enough to gargle without swallowing the water, usually around age six or seven. Ice pops and cold fruit bars are popular with kids for obvious reasons and provide the same cold-numbing and hydration benefits as ice chips for adults. Honey is safe and effective for children over 12 months old, but as noted earlier, it must be strictly avoided for infants under one year due to the risk of botulism.16The Journal of Pediatrics. Honey and other environmental risk factors for infant botulism
For very young children who cannot gargle or suck on lozenges safely, warm broth, cold fluids, and age-appropriate doses of acetaminophen or ibuprofen are the main options. Throat sprays and lozenges are choking hazards for toddlers and should not be given to children under about four years old. If a young child refuses to drink because swallowing hurts too much, that is a reason to call the pediatrician, since dehydration can become a problem fast in small bodies.
