The Proven Benefits and Science of Manuka Honey
Discover how Manuka honey’s unique properties support wound healing, oral health, and more, backed by science and tradition.
What Is Manuka Honey?
Manuka honey is a special type of honey originating from New Zealand, created by bees that pollinate the blossoms of the Leptospermum scoparium, also known as the Manuka bush. Praised for its distinctive flavor and superior antibacterial properties, Manuka honey has gained worldwide attention for its functional health benefits that go far beyond those of regular honey.
- Origin: Made by bees in New Zealand from the Manuka bush.
- Unique Ingredient: Contains high levels of methylglyoxal (MGO), which delivers potent antibacterial effects.
- Traditional Uses: Used for centuries in Maori medicine and global folk healing.
The distinguishing factor in Manuka honey is its methylglyoxal content, verified by a grading system measuring its unique Manuka factor (UMF).
What Sets Manuka Honey Apart?
- Antibacterial Power: Manuka honey’s MGO levels are up to 20 times higher than those found in conventional honey.
- UMF Certification: UMF stands for Unique Manuka Factor; higher UMF = more potent bioactivity.
- Active Compounds: Rich in antioxidants, flavonoids, amino acids, vitamins, and phytochemicals.
Unlike regular honey, Manuka honey has been clinically studied for its ability to support healing, immunity, and other functions due to its unique profile.
6 Science-Backed Benefits of Manuka Honey
Modern research reveals that Manuka honey delivers a range of therapeutic benefits:
- Wound healing
- Promotes oral health
- Calms coughs
- Helps prevent gastric ulcers and supports digestive wellness
- Antibacterial and anti-inflammatory action
- Potential support for cystic fibrosis and skin conditions
1. Aids in Wound Healing
Honey has been used to treat wounds since ancient times, and Manuka honey’s unique antibacterial and antioxidant properties make it especially effective.
- Maintains a moist barrier and prevents infections at wound sites.
- Promotes tissue regeneration and reduces pain from burns and sores.
- Helps heal diabetic ulcers and wounds exposed to resistant bacteria like MRSA.
- Stimulates macrophages (immune cells) to release healing cytokines.
Important: Manuka honey can be used as a complementary remedy for chronic wounds, but should not substitute professional medical care for serious injuries.
2. Supports Oral Health
Studies indicate that Manuka honey can help maintain oral health by reducing harmful bacteria responsible for gum inflammation, plaque formation, and tooth decay.
- Suppresses bacteria implicated in gingivitis and periodontitis.
- Unlike table sugar, Manuka honey does not promote cavity formation.
- Regular use in oral rinses can support overall mouth hygiene.
With built-in antimicrobial action, Manuka honey offers a natural way to boost oral wellness when used responsibly.

3. Calms Coughs and Soothes Sore Throats
Manuka honey’s thick consistency and antimicrobial properties can provide rapid relief from coughs and throat irritation.
- Coats mucous membranes in the throat, reducing irritation and discomfort.
- Reduces bacteria contributing to upper respiratory tract infections.
- Often used in home remedies for children (age-appropriate) and adults.
Though not a substitute for antibiotics, it can be a supportive measure for soothing symptoms and recovering from minor illnesses.
4. Digestive Health and Ulcer Prevention
Manuka honey may promote gut health and help prevent or alleviate ulcers.
- Fights off Helicobacter pylori, a bacterium linked to stomach ulcers.
- Improves tissue healing and may assist in the management of gastric and intestinal ulcers.
- Polyphenols and antioxidants in Manuka honey are linked to positive gut microbiota balance.
Evidence suggests regular consumption of Manuka honey does not disrupt gut microbiota or trigger negative side effects.
5. Antibacterial, Anti-inflammatory, and Antioxidant Properties
Manuka honey’s health-promoting power comes mainly from its high methylglyoxal (MGO) levels.
- Inhibits growth of a variety of pathogens, including Staphylococcus aureus.
- Reduces oxidative stress and inflammation, thanks to its rich antioxidant content.
- Helps modulate immune response, aiding in healing and recovery.
These combined effects make Manuka honey highly prized as both a food and a topical agent.
6. Research in Cancer and Chronic Disease Prevention
Emerging research from UCLA Health and other institutions has shown Manuka honey displays anti-tumor effects in preclinical studies.
- Reduces tumor growth in ER-positive breast cancer models by 84%.
- Targets cancer cells without harming normal healthy cells.
- Enhances the effectiveness of breast cancer drugs such as tamoxifen.
- Contains flavonoids and phytochemicals with potential to block cancer-promoting pathways.
Note: These results are preliminary and require further human clinical trials. They highlight the possible expanded role for Manuka honey in chronic disease management.
How Safe Is Manuka Honey?
Clinical trials confirm that Manuka honey is safe to consume at tested doses for healthy individuals.
- No adverse effects observed in short-term studies of biomarkers (IgE, CML levels).
- Does not disrupt healthy gut microbiome composition.
Exceptions:
- Infants under 12 months should NOT consume any honey due to risk of botulism.
- Diabetics and those sensitive to sugars should moderate intake.
- Check for allergies before use, especially in topical treatments.
How to Choose Authentic Manuka Honey
Not all products labeled “Manuka honey” deliver the same health benefits. To ensure authenticity and efficacy:
- Look for the “UMF” or “MGO” grading on the label. Higher values indicate higher bioactivity.
- Purchase from reputable suppliers in New Zealand or certified international brands.
- Check for a batch number or traceability details.
High-quality options may cost more, but are better for medicinal and culinary uses.
Best Ways to Use Manuka Honey
- Apply a thin layer directly to minor burns, skin wounds, or abrasions after cleaning (ask your doctor first).
- Mix into herbal teas to soothe sore throats or coughs.
- Enjoy a teaspoon daily for digestive health, but don’t exceed recommended serving sizes (often one tablespoon per day).
- Use as a natural sweetener for smoothies, yogurt, or healthy baking recipes.
- Some research supports oral rinses using diluted Manuka honey for gum health.
Potential Side Effects and Precautions
- High Sugar Content: Contains natural sugars—consume cautiously if you have diabetes.
- Infant Risk: Never give honey to babies under one year, due to risk of botulism.
- Possible Allergies: Allergic reactions are rare, but possible—test small amounts at first.
- Pregnancy and Medical Treatments: Consult your doctor before using for wound care or as a supplement if pregnant or on medication.
