What is Manuka honey used for? Benefits, uses, and scientific evidence

What is the use of Manuka honey? A scientific overview

Manuka honey is generating increasing interest for its therapeutic benefits and everyday uses. Originating in New Zealand and southeastern Australia, this specific honey is renowned for its unique antibacterial properties, linked to components such as methylglyoxal (MGO) and the Unique Manuka Factor (UMF). In this article, we explain in detail what Manuka honey is used for, what scientific evidence supports its benefits, and how to choose and use it safely.

What is Manuka honey?

Manuka honey is produced by bees that forage on the flowers of Leptospermum scoparium, commonly known as the manuka shrub. Unlike regular honeys, it contains specific organic compounds—primarily methylglyoxal (MGO)—responsible for its higher antibacterial activity. Manufacturers often use indices such as UMF or MGO to certify the product's antibacterial potency.

Active components and quality indices

The two most commonly used reference points are:

• MGO : indicates the level of methylglyoxal. The higher the value, the stronger the antibacterial activity.
• UMF : Proprietary scale which includes MGO and other markers such as leptospermone; it guarantees authenticity and traceability.

Manuka honey labeled UMF 10+ or ​​MGO 250+ is considered active for common health uses, while higher indices are suitable for more targeted therapeutic applications.

Main uses of Manuka honey

Manuka honey has several uses, supported by studies or clinical experience:

1. Antibacterial properties and wound healing

Manuka honey is used in medical settings and at home to promote wound healing. Its ability to inhibit the growth of many bacteria, including resistant strains, facilitates tissue repair. It is found in medical dressings and specific products for wounds, ulcers, and minor burns.

2. Treatment of skin infections

When applied topically, it can reduce inflammation and limit bacterial growth in superficial infections (acne, minor cuts, interdigital infections). Some clinical studies show improved healing compared to conventional treatments in certain cases.

3. Oral Health

Manuka honey has antibacterial properties that can help reduce plaque and gum inflammation. Mouthwashes or gels containing Manuka are sometimes offered to improve oral hygiene, but they are not a substitute for regular dental care.

4. Digestive problems

Some people use Manuka honey to soothe mild digestive issues (reflux, gastritis, H. pylori). In vitro studies suggest activity against Helicobacter pylori, but clinical evidence remains limited and requires caution and should be used in conjunction with medical advice.

5. Relief from coughs and sore throats

Like other honeys, Manuka honey can soothe the throat and reduce the frequency of nighttime coughs in children and adults. Its texture and antibacterial compounds make it a popular natural remedy for relieving mild respiratory symptoms.

What does the research say?

Scientific literature shows that Manuka honey possesses superior antibacterial activity compared to many other honeys, primarily attributed to MGO. In vitro studies and controlled clinical trials have demonstrated positive results in wound healing and reducing local bacterial load. However, efficacy varies depending on the concentration (UMF/MGO), product quality, and the nature of the condition being treated.

How to choose your Manuka honey?

The choice is based on objective criteria:

• UMF index or MGO level : choose according to the use — UMF 5-10 for daily food consumption, UMF 10+ or ​​15+ for health uses, and UMF 20+ for specific therapeutic needs.
• Traceability : favour certified labels (UMF, Active MGO) and producers who are transparent about origin.
• Purity : check that it is pure honey, without mixing or excessive heating, as heat damages the active compounds.
• Packaging and storage : an opaque jar and storage away from heat preserve the quality.

Dosage and instructions for use

For internal use, one teaspoon per day of UMF 10+ Manuka honey is generally considered safe for an adult. For topical use (wounds, skin), apply a thin layer and then cover according to medical recommendations or the product instructions. In case of severe infection, follow medical advice and do not use honey as the sole treatment.

Precautions and side effects

• Do not give honey to children under 12 months (risk of infant botulism).
• Monitoring in diabetic individuals: honey contains sugars and can impact blood glucose levels.
• Allergies: rare but possible in people sensitive to bee products.
• Drug interactions: generally low, but in case of specific treatment, seek the advice of a healthcare professional.

FAQ

Does Manuka honey heal wounds better than conventional treatments?

Several studies show that Manuka can accelerate healing and reduce bacterial load in certain types of wounds. However, it does not replace medical treatment when the wound is deep, infected, or requires specialized care.

What is the difference between UMF and MGO?

UMF is a global label that takes into account several markers, while MGO specifically indicates the concentration of methylglyoxal. Both help to assess antibacterial potency.

Can I use Manuka honey every day?

Yes, in moderate dietary intake (one spoonful per day) to benefit from potential anti-inflammatory and digestive effects. Adjust the quantity according to your metabolic state (diabetes) and consult a professional if in doubt.

Is it possible to store supplies at home?

Store Manuka honey in a dry, dark place at room temperature. Avoid refrigeration, which makes it more solid and less convenient to use.

Summary and practical recommendations

Manuka honey is primarily used as a natural antibacterial agent, a wound-healing aid, and a complementary remedy for certain minor skin, digestive, and ENT (ear, nose, and throat) conditions. For daily use, choose a certified UMF/MGO product; for medicinal purposes, opt for higher concentrations and consult a healthcare professional.

Conclusion

What is Manuka honey used for? It provides superior antibacterial and healing properties compared to ordinary honeys, making it useful in both cosmetics/skincare and for moderate internal use. While the evidence is encouraging, caution is advised: choose certified products, respect contraindications, and consult a professional when necessary. Use it as a natural supplement, not as a systematic replacement for medical treatments.
