Honey for Sore Throat and Cough: What Science Says
Studies confirm what grandmothers have known for generations: honey really does help sore throats and coughs. Here's the research and the best ways to use it.
When you wake up with a scratchy throat or a nagging cough, reaching for honey is not just an old wives' tale—it is backed by serious science. Multiple peer-reviewed studies have found that honey performs as well as, or better than, many over-the-counter cough suppressants. Major health organizations including the World Health Organization now recommend honey as a first-line treatment for coughs.
This comprehensive guide examines what researchers have discovered, explains why honey works, and provides practical protocols for using it effectively.
The Research: What Studies Actually Show
The Landmark Penn State Study (2007)
A groundbreaking study published in the Archives of Pediatrics & Adolescent Medicine compared three treatments for children with upper respiratory infections: honey, dextromethorphan (DM, the active ingredient in most cough syrups), and no treatment.
Study design:
- 105 children ages 2-18 with upper respiratory infections
- Random assignment to honey, honey-flavored DM, or no treatment
- Parents rated cough frequency, cough severity, and sleep quality
Results:
Honey outperformed both alternatives across all measures:
- Cough frequency: Honey provided the greatest reduction
- Cough severity: Honey was most effective
- Sleep quality for children: Honey produced the best improvement
- Sleep quality for parents: Honey again performed best
The researchers concluded that honey "may be a preferable treatment for the cough and sleep difficulty associated with childhood upper respiratory tract infection."
The Cochrane Review (2012, 2018 updates)
Cochrane Reviews are considered the gold standard for medical evidence. Their systematic review of honey for acute cough examined multiple randomized controlled trials.
Key findings:
- Honey probably reduces cough symptoms more effectively than no treatment
- Honey may be more effective than diphenhydramine (Benadryl)
- Honey performs comparably to dextromethorphan
- No serious adverse effects were reported
The review noted that while evidence quality varied, the consistent direction of results across studies supported honey's effectiveness.
The BMJ Evidence-Based Medicine Review (2020)
A more recent systematic review and meta-analysis examined 14 studies with nearly 1,800 participants. Published in BMJ Evidence-Based Medicine, this comprehensive analysis concluded:
- Honey was more effective than usual care for improving cough symptoms
- Effects were particularly significant for cough frequency and cough severity
- Honey provided a safe, widely available, and cheap alternative to antibiotics
The researchers specifically noted honey's potential as an alternative to antibiotic prescriptions for upper respiratory infections, which often receive antibiotics despite being viral (and thus unresponsive to antibiotics).
WHO Recommendation
The World Health Organization includes honey in its guidelines for treating coughs in children. The WHO states that honey can be used as a demulcent (soothing agent) for cough relief in children over one year of age.
This official recognition from a major global health organization reflects the accumulated evidence supporting honey's effectiveness.
Additional Supporting Research
Numerous other studies support honey's efficacy:
Malaysian study (2010): Found honey significantly more effective than a placebo for nocturnal cough in children.
Israeli study (2012): Compared three types of honey (eucalyptus, citrus, and labiatae) to placebo and found all three improved cough symptoms and sleep quality.
Iranian study (2013): Found honey combined with coffee more effective than prednisolone (a steroid medication) for persistent post-infectious cough.
Why Honey Works: The Mechanisms
Honey's effectiveness against coughs and sore throats stems from multiple complementary mechanisms:
Demulcent Effect
Honey's thick, viscous texture physically coats and soothes irritated throat tissue. This mechanical barrier:
- Protects nerve endings from irritation
- Reduces the tickling sensation that triggers coughing
- Provides immediate (though temporary) relief
- Lubricates dry, inflamed tissue
The demulcent effect explains why honey provides near-instant relief—within seconds of swallowing, you feel the soothing coating.
Antimicrobial Properties
Raw honey contains multiple antimicrobial compounds that may help fight infection:
Hydrogen peroxide: Produced by the enzyme glucose oxidase, this provides broad-spectrum antibacterial activity.
Methylglyoxal: Found in varying amounts depending on floral source (highest in Manuka honey), this compound has potent antibacterial effects.
Bee defensin-1: An antimicrobial peptide bees add to honey during production.
Low water activity: Honey's high sugar concentration and low moisture create an environment hostile to bacteria.
Acidic pH: Honey's pH of 3.2-4.5 inhibits many bacterial species.
While honey will not cure a viral infection (the cause of most coughs), its antimicrobial properties may:
- Help prevent secondary bacterial infections
- Reduce bacterial load in the throat
- Support the body's natural immune response
Anti-Inflammatory Action
Chronic inflammation in throat tissue worsens cough symptoms. Honey contains:
Flavonoids: Including chrysin, pinocembrin, and pinobanksin
Phenolic acids: Such as caffeic acid and ferulic acid
Other antioxidants: That reduce oxidative stress
These compounds reduce inflammation in irritated tissues, decreasing swelling and pain. Studies have shown honey's anti-inflammatory effects comparable to some pharmaceutical agents.
Salivation Stimulation
Honey's sweetness stimulates salivary glands, producing more saliva that:
- Naturally lubricates and soothes the throat
- Helps thin mucus for easier clearing
- Contains its own antimicrobial compounds (lysozyme, lactoferrin)
- Maintains moisture in oral and throat tissues
Central Cough Suppression
Emerging research suggests honey may affect the brain's cough center similarly to dextromethorphan, but through different pathways. The sweet taste appears to trigger neurological responses that dampen the cough reflex.
One theory involves opioid receptors—sweet tastes release endorphins that may suppress cough signaling. This would explain why honey's effectiveness exceeds what its physical properties alone would predict.
Osmotic Effects
Honey's high sugar concentration creates osmotic pressure that:
- Draws fluid from inflamed tissues (reducing swelling)
- May help thin mucus secretions
- Creates an environment difficult for pathogens
How to Use Honey for Maximum Effectiveness
Basic Dosing
Adults and children over 12:
- 1-2 teaspoons (5-10 ml) as needed
- Can be repeated every 2-3 hours
- Take before bed for nighttime cough
Children 6-12 years:
- 1 teaspoon (5 ml) as needed
- Up to 4 times daily
Children 1-5 years:
- ½ teaspoon (2.5 ml) as needed
- Up to 3 times daily
Children under 1 year:
- NEVER give honey to infants due to botulism risk
Method 1: Straight from the Spoon
The simplest and often most effective method:
- Measure honey onto a spoon
- Let it slide slowly down your throat
- Resist the urge to swallow quickly
- Allow the honey to coat throat tissues
- Avoid drinking for 10-15 minutes to maintain coating
This direct approach maximizes the demulcent effect by keeping honey in contact with irritated tissue longer.
Method 2: Honey and Warm Water
For those who find straight honey too sweet:
- Heat water to warm (not hot—below 110°F to preserve enzymes)
- Dissolve 1-2 tablespoons honey in 1 cup water
- Sip slowly, allowing liquid to coat the throat
- Can add lemon juice for additional vitamin C
This method also provides hydration, important during illness.
Method 3: Honey and Lemon
The classic combination:
Ingredients:
- 1 tablespoon raw honey
- Juice of half a lemon
- 1 cup warm water
Instructions:
- Heat water to warm (not boiling)
- Add lemon juice
- Stir in honey until dissolved
- Sip slowly
Why it works: Lemon adds vitamin C for immune support and acidic compounds that may enhance antimicrobial effects. The combination is more palatable than honey alone for many people.
Method 4: Honey Ginger Tea
For additional soothing and anti-inflammatory benefits:
Ingredients:
- 2-inch piece fresh ginger, sliced
- 2 cups water
- 2 tablespoons raw honey
- Optional: lemon juice
Instructions:
- Bring water and ginger to a boil
- Reduce heat and simmer 10 minutes
- Strain into cups
- Let cool to warm temperature
- Stir in honey
- Add lemon if desired
Ginger provides additional anti-inflammatory compounds and helps settle nausea that sometimes accompanies illness.
Method 5: Honey and Herbal Tea
Combine honey with throat-soothing herbs:
Best herbs for sore throats:
- Marshmallow root: Additional demulcent effect
- Slippery elm: Coats and soothes
- Licorice root: Anti-inflammatory and soothing (avoid with high blood pressure)
- Chamomile: Calming and mildly anti-inflammatory
- Peppermint: Cooling sensation, may help with congestion
Method:
- Brew herbal tea according to package directions
- Let cool to drinking temperature
- Add 1-2 teaspoons honey
- Sip slowly
Method 6: Nighttime Protocol
For maximum nighttime relief:
30 minutes before bed:
- Take 1 tablespoon honey straight
- Follow with warm honey-lemon water
- Use a humidifier in bedroom
- Elevate head slightly when sleeping
This protocol addresses cough from multiple angles and often provides significant improvement in sleep quality.
Which Honey Works Best?
Raw vs. Processed
For sore throats and coughs, raw honey offers advantages:
Raw honey provides:
- Active enzymes with antimicrobial properties
- Full spectrum of antioxidants and flavonoids
- Intact bee pollen and propolis compounds
- Maximum antibacterial activity
Processed honey loses:
- Most enzyme activity (destroyed by heat)
- Significant antioxidant content
- Pollen and propolis
- Some antimicrobial effectiveness
For medicinal purposes, raw honey is the better choice.
Darker vs. Lighter Honey
Research indicates darker honeys contain higher antioxidant levels:
Buckwheat honey: Very dark, robust flavor, highest antioxidant content. Multiple studies have specifically used buckwheat honey with excellent results.
Manuka honey: Contains high levels of methylglyoxal (MGO), providing enhanced antibacterial properties. More expensive but may be worth it for stubborn infections.
Wildflower honey: Variable depending on floral sources. Generally good balance of properties and flavor.
Clover honey: Lighter, milder. Still effective but may contain fewer antioxidants.
For coughs and sore throats, buckwheat honey has the strongest research support, but any raw honey will help.
Local vs. Non-Local
For cough and sore throat relief specifically, local origin matters less than it does for allergy purposes. Any quality raw honey from any region will work for symptomatic relief.
Honey vs. Over-the-Counter Medications

When to Choose Honey
- Children over 1 year (when OTC options have age restrictions)
- When you want to avoid drug side effects
- For nighttime use when you need sleep
- When you prefer natural remedies
- For mild to moderate coughs
- As a first-line treatment before trying medications
When Medications May Be Appropriate
- Severe symptoms not responding to honey
- When specific medication benefits are needed (antihistamine for allergies, etc.)
- As directed by healthcare provider
- When honey is not available
Important Cautions and Contraindications
Never Give Honey to Infants Under 12 Months
This cannot be stressed enough. Honey may contain Clostridium botulinum spores that infant digestive systems cannot handle, potentially causing infant botulism—a serious, potentially fatal illness.
This applies to ALL honey:
- Raw or pasteurized
- Local or imported
- Any variety or source
Pasteurization does not destroy botulism spores. There are no exceptions to this rule.
People with Bee Allergies
If you have known allergies to bee stings, bee pollen, or other bee products, exercise caution with honey—particularly raw, unfiltered varieties. Start with a tiny amount and monitor for reactions.
Diabetes
Honey affects blood sugar. If you have diabetes:
- Count honey toward your carbohydrate intake
- Monitor blood sugar when using honey for illness
- Consider that illness itself affects blood sugar
- Consult your healthcare provider
Not a Cure for Underlying Conditions
While honey effectively soothes symptoms, it does not:
- Kill viruses causing your cold
- Cure bacterial infections (though it may help)
- Replace medical treatment for serious conditions
Seek medical attention if:
- Symptoms persist beyond 7-10 days
- You develop high fever (over 101.3°F)
- You have difficulty breathing
- Symptoms significantly worsen
- You have underlying health conditions
Dental Considerations
Honey is sticky and contains sugars. After using honey for throat relief:
- Rinse with water if possible
- Do not brush teeth immediately (can spread honey to more tooth surfaces)
- Wait 30 minutes before brushing
- Consider dental health in choosing frequency of use
Making It Part of Your Cold Care Routine
At the First Sign of Symptoms
When you notice throat scratchiness or tickling:
- Take 1 teaspoon of raw honey immediately
- Follow with warm honey-lemon water
- Repeat every 2-3 hours
Early intervention often reduces symptom severity and duration.
Throughout the Day
- Take honey before meals to avoid nausea
- Stay hydrated between honey doses
- Use throat lozenges with honey for convenience when out
- Keep a honey jar at your desk or workspace
At Bedtime
The most important dose is before sleep, when coughing typically worsens:
- Take 1 tablespoon of honey 30 minutes before bed
- Use a humidifier
- Elevate your head
- Keep honey by bedside for middle-of-night symptoms
The Recovery Period
Continue honey use even as symptoms improve:
- Residual irritation benefits from continued soothing
- Preventing cough helps tissue heal
- Tapering off gradually is fine
Frequently Asked Questions
How quickly does honey work?
The demulcent (coating) effect is immediate—within seconds. Cough suppression typically begins within 15-30 minutes. Most studies show significant improvement in overnight cough within the first night of use.
Can I use honey with other cold medications?
Generally yes, but:
- Space them out if taking multiple cough suppressants
- Be aware of total symptom medication you're taking
- Consult pharmacist if unsure about interactions
- Watch for additive drowsiness with sedating medications
Is it OK to heat honey for tea?
For cough relief, warm (not hot) temperatures are ideal. Very hot liquids may degrade some beneficial enzymes, but the demulcent and antimicrobial properties largely remain. Warm honey-lemon water is a perfectly valid approach.
How much honey is too much when sick?
There is no strict upper limit, but practical guidelines:
- 3-4 tablespoons daily is reasonable for adults
- More than this adds significant calories without additional benefit
- Monitor for digestive upset at higher doses
- Balance against total sugar intake
Why does my cough get worse at night?
Several factors contribute:
- Lying down allows post-nasal drip to trigger cough
- Decreased swallowing during sleep reduces throat clearing
- Dry bedroom air irritates tissues
- Circadian variations in inflammation
This is why bedtime honey dosing is particularly important.
The Bottom Line
Honey is one of the few natural remedies with strong scientific support for a common health complaint. Multiple high-quality studies demonstrate that honey performs as well as or better than standard cough medicines, with fewer side effects and additional health benefits.
For adults and children over one year, honey is an excellent first-line treatment for coughs and sore throats associated with upper respiratory infections. It works through multiple mechanisms—coating and soothing tissue, reducing inflammation, fighting microbes, and potentially suppressing the cough reflex at a neurological level.
