Honey for Sore Throat and Cough: What the Research Says

Honey Is a Clinically Proven Cough Remedy

Reaching for honey when you have a cough is not just a folk remedy — it is backed by a substantial body of clinical research. A 2020 systematic review published in BMJ Evidence-Based Medicine analyzed 14 studies and concluded that honey was superior to usual care for improving upper respiratory tract symptoms, particularly cough frequency and severity.

The World Health Organization (WHO) has recommended honey as a first-line treatment for cough in children over one year old since 2001. The American Academy of Pediatrics also endorses honey for nighttime cough relief in children aged 1 and older. For adults, multiple randomized controlled trials have found honey performs as well as or better than dextromethorphan (the active ingredient in most OTC cough syrups) — without the drowsiness or other side effects.

How Honey Works Against Cough and Sore Throat

Honey relieves cough and sore throat through several mechanisms working together. Understanding these helps explain why honey is effective and why not all honeys perform equally.

• Demulcent coating — Honey's thick, viscous texture coats the irritated mucous membranes of the throat, creating a protective barrier that reduces the tickle sensation triggering the cough reflex
• Osmotic effect — Honey's high sugar concentration (about 80%) draws water from inflamed throat tissues, reducing swelling and discomfort
• Antimicrobial action — Hydrogen peroxide produced by the enzyme glucose oxidase, plus low pH (3.2-4.5) and low water activity, inhibit bacterial growth in the throat
• Antioxidant properties — Flavonoids and phenolic compounds in honey reduce oxidative stress and inflammation in irritated airways
• Salivation stimulation — Honey's sweetness triggers saliva production, which naturally soothes and lubricates the throat

Which Honey Is Best for Cough and Sore Throat?

Not all honey is equally effective for throat relief. Research consistently shows that darker honeys have higher antioxidant content and stronger antimicrobial properties, making them better choices for medicinal use.

• Buckwheat honey — The standout performer in cough studies. A landmark 2007 Penn State study found buckwheat honey outperformed dextromethorphan for nighttime cough in children. Its dark color indicates high antioxidant content
• Manuka honey — Contains methylglyoxal (MGO), a unique antimicrobial compound not found in other honeys. UMF 10+ or MGO 263+ is recommended for therapeutic use. More expensive but has the strongest evidence for antibacterial activity
• Wildflower honey — A good middle-ground option that is widely available, reasonably priced, and contains diverse plant compounds from multiple nectar sources
• Eucalyptus honey — Contains trace amounts of eucalyptol, which has natural decongestant properties. Particularly good when congestion accompanies the cough
• Raw honey (any variety) — Always choose raw over processed. Pasteurization destroys the beneficial enzymes and reduces antioxidant content that make honey medicinally effective

Dosing: How Much Honey to Take

Clinical trials have used fairly consistent dosing, making it easy to replicate the studied amounts at home. For general daily intake guidance, see our guide on how much honey per day.

• Adults — 1 to 2 tablespoons (15-30 ml) of honey, taken straight or dissolved in warm water or tea. Can be repeated every 2-3 hours as needed
• Children (ages 1-5) — Half a teaspoon (2.5 ml) before bedtime
• Children (ages 6-11) — One teaspoon (5 ml) before bedtime
• Children (ages 12+) — Two teaspoons (10 ml) or adult dose
• For nighttime cough — Take the dose 30 minutes before bed. Most studies showing improved sleep quality used bedtime dosing

5 Honey Remedies for Sore Throat and Cough

Straight honey works well on its own, but combining it with other natural ingredients can enhance the effect. These remedies are backed by traditional use and some clinical evidence.

• Honey and lemon in warm water — The classic combination. Lemon provides vitamin C and citric acid, which helps break up mucus. Mix 1-2 tablespoons honey and the juice of half a lemon in a mug of warm (not boiling) water. Drink 2-3 times daily
• Honey and ginger tea — Ginger contains gingerols with anti-inflammatory and antiemetic properties. Steep 1 inch of fresh sliced ginger in hot water for 10 minutes, let cool slightly, then stir in 1-2 tablespoons of honey
• Honey and turmeric paste (golden honey) — Mix 1 tablespoon of raw honey with 1/4 teaspoon of turmeric powder. Turmeric's curcumin is a potent anti-inflammatory. Take half a teaspoon of the paste every hour during acute sore throat, reducing frequency as symptoms improve
• Honey and apple cider vinegar gargle — Mix 1 tablespoon honey and 1 tablespoon raw ACV in a cup of warm water. Gargle for 15-20 seconds, then swallow. The acidity helps create an inhospitable environment for throat bacteria
• Honey and cinnamon — Mix 1 tablespoon of honey with 1/4 teaspoon of Ceylon cinnamon. Cinnamon has antimicrobial properties that complement honey's. Take directly or stir into warm water

Important Safety Warnings

Honey is safe for most people, but there are critical exceptions and precautions to be aware of.

• NEVER give honey to infants under 12 months — Honey can contain Clostridium botulinum spores. An infant's immature digestive system cannot neutralize these spores, risking infant botulism — a potentially life-threatening condition. This applies to all honey, including raw and pasteurized. See our honey during pregnancy guide for more on safety during pregnancy and early childhood
• Diabetics should count honey as sugar — While honey has a lower glycemic index than table sugar (58 vs. 65), it still significantly raises blood glucose. One tablespoon contains about 17g of sugar. Monitor your levels and consult your doctor
• Allergy risk is rare but real — People with severe pollen allergies may rarely react to raw honey containing the specific pollen they are allergic to. If you have a known severe pollen allergy, start with a very small amount
• Honey is not a replacement for medical care — If your cough lasts more than 3 weeks, produces blood, or is accompanied by high fever, difficulty breathing, or unexplained weight loss, see a doctor. Honey treats symptoms, not underlying conditions like pneumonia or asthma
• Drug interactions — Honey may interact with blood thinners (warfarin) due to its vitamin K content. If you take blood-thinning medication, consult your doctor before consuming large amounts of honey regularly

Honey vs. OTC Cough Medicine: How They Compare

One of the most interesting findings in recent research is that honey consistently matches or outperforms common cough medications in head-to-head trials.

A Cochrane review found that honey reduced cough frequency better than diphenhydramine and was comparable to dextromethorphan. Importantly, honey had fewer side effects: no drowsiness, no dizziness, and no risk of accidental overdose that comes with OTC medications, particularly in children.

The American College of Chest Physicians noted that OTC cough suppressants have limited evidence of efficacy in adults and should not be used in children under 6. Honey, by contrast, has positive trial data in children as young as 1 year old.

This does not mean you should never use cough medicine. Productive coughs, bacterial infections, and chronic respiratory conditions need proper medical treatment. But for the common upper respiratory infection — the typical cold or mild flu that causes most coughs — honey is a safe, effective, and evidence-based first choice.

When to See a Doctor Instead of Reaching for Honey

Honey is appropriate for symptom relief during typical upper respiratory infections. It is not a treatment for serious conditions. Seek medical attention if you experience any of these:

• Cough lasting more than 3 weeks
• Coughing up blood or blood-streaked mucus
• Fever above 103°F (39.4°C) or fever lasting more than 3 days
• Difficulty breathing, wheezing, or shortness of breath
• Chest pain when coughing
• Unexplained weight loss alongside chronic cough
• Symptoms worsening after initial improvement (possible secondary infection)

Beyond Honey: Bee Products for Respiratory Health

Honey is the most studied bee product for cough and sore throat, but it is not the only one worth considering. Other bee-derived products offer complementary respiratory benefits that can be combined with honey for a more comprehensive approach.

Propolis — the resinous substance bees use to seal and sterilize their hives — has stronger antimicrobial properties than honey for certain pathogens. A randomized controlled trial found that propolis spray reduced the duration of upper respiratory symptoms by 63% compared to placebo. Propolis throat sprays deliver antimicrobial compounds (particularly CAPE and flavonoids) directly to inflamed throat tissue. Look for propolis extract sprays standardized to flavonoid content.

For coughs accompanied by significant sinus congestion, honey alone addresses the throat but not the nasal passages. Combining a honey-based throat remedy with a honey-enhanced saline nasal rinse targets both the upper and lower respiratory symptoms. A 2014 RCT published in the International Forum of Allergy & Rhinology found that Manuka honey nasal irrigation improved symptoms in chronic rhinosinusitis patients beyond saline alone.

The anti-inflammatory properties of honey explain why it works for the inflammatory component of sore throats, not just the infectious one. Honey's polyphenols inhibit the NF-κB inflammatory pathway — the same pathway targeted by ibuprofen. This is why honey can relieve sore throat pain even when the cause is viral (where antibacterial activity is irrelevant). Pairing honey with cinnamon, which contains its own anti-inflammatory cinnamaldehyde, amplifies this effect.
