Manuka Honey Wounds: A Comprehensive Review of Research Findings
Manuka honey has garnered significant attention in wound care from medical professionals and researchers alike. This article delves into the scientific evidence supporting the use of Manuka honey for wound treatment, exploring its unique properties.

The Science Behind Manuka Honey and Wounds
Manuka honey, produced only in New Zealand, possesses exceptional antibacterial properties. The efficacy of Manuka honey is attributed to its high concentration of methylglyoxal (MGO), which is responsible for its Unique Manuka Factor (UMF).

Antibacterial Properties
Research has consistently demonstrated the potent antibacterial activity of Manuka honey against a wide range of pathogens commonly found in wounds. Studies have shown that Manuka honey is effective against both planktonic bacteria and biofilms, including antibiotic-resistant strains such as Methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE).
In a randomised trial comparing Manuka honey to hydrogel dressings on venous leg ulcers (Gethin and Cowman, Journal of Wound Care, 2008), 70% of MRSA-infected wounds treated with Manuka honey showed complete eradication of the bacteria after four weeks, compared to only 16% in the hydrogel group. This highlights the superior antibacterial efficacy of Manuka honey in managing infected wounds.
Wound Healing
- Rapid Debridement: Manuka honey facilitates the removal of dead tissue and slough, which can impede healing and harbour bacteria.
- Anti-inflammatory Effects: It suppresses prolonged inflammatory responses while stimulating the production of pro-inflammatory cytokines, allowing for normal healing processes. In a lab study, a component of Manuka honey stimulated immune cells to release the cytokine TNF-alpha (Tonks et al., Journal of Leukocyte Biology, 2007).
- Tissue Regeneration: Manuka honey promotes the growth of tissues for wound repair, enhancing granulation tissue formation, angiogenesis, and re-epithelialisation.
Clinical Evidence for Manuka Honey Wounds
A clinical study conducted on 15 patients with chronic non-healing discharging extra-oral wounds provided compelling evidence for the efficacy of Manuka honey in wound care. The study found that Manuka honey dressings, used in conjunction with antibiotic treatment, led to complete cessation of pus discharge within the first week of application. Over four weeks, the average wound depth decreased significantly, with complete wound epithelialisation observed.
Another study focusing on horse wounds (an animal study from the University of Sydney, 2017) found that Manuka honey with a higher UMF rating (UMF 20) healed wounds faster than generic honey or no treatment, with UMF 5 honey in between. This suggests that the concentration of active compounds in Manuka honey plays a crucial role in its wound-healing properties.
The strongest clinical evidence is for burns. A Cochrane review (Jull and colleagues, 2015) found high quality evidence, from two trials with 992 people, that honey dressings heal partial-thickness burns around 4 to 5 days more quickly than conventional dressings.

Unique Manuka Factor (UMF) and Its Importance
Research has shown that higher UMF ratings correlate with increased antibacterial activity.
Manuka Honey Wounds: Comparison with Other Treatments
Studies have compared the efficacy of Manuka honey to other wound treatments, including silver-based dressings. Manuka honey has shown comparable or superior results in many cases, with the added benefits of no known bacterial resistance and low cytotoxicity.
Advantages of Manuka Honey in Wound Care
- Broad-spectrum antimicrobial activity: Effective against a wide range of bacteria, including antibiotic-resistant strains.
- No known bacterial resistance: Bacteria have not developed resistance to Manuka honey.
- Low cytotoxicity: Manuka honey does not harm healthy tissue.
- Autolytic debridement: Promotes the removal of dead tissue and slough from the wound bed.
- Odour neutralisation: Helps reduce unpleasant odours associated with infected wounds.

Safety
Manuka honey has shown particular promise in diabetic foot wounds, where medical-grade Manuka honey debrided wounds faster than a chemical debriding agent. The use of Manuka honey has been associated with reduced inflammation and debridement time.
One thing to know: honey from a jar is a food and isn't sterile, so keep it for eating. Only medical-grade honey is registered as a medical device for wound management (Journal of Community Nursing, 2014).
Future Directions in Manuka Honey Wounds Research
While the current evidence supporting the use of Manuka honey in wound care is promising, further research is needed to fully understand its mechanisms of action and optimise its use in clinical practice. Future studies should focus on:
- Determining the optimal UMF ratings for different types of wounds.
- Investigating the long-term effects of Manuka honey on wound healing and scar formation.
- Exploring potential synergistic effects when combining Manuka honey with other wound care treatments.
- Conducting large-scale clinical trials to establish standardised protocols for manuka honey wound treatment.
Conclusion
The scientific evidence supporting the use of Manuka honey in wound care is compelling.

Frequently Asked Questions
What makes manuka honey antibacterial?
Manuka honey's high concentration of methylglyoxal (MGO) gives it potent antibacterial properties.
Can manuka honey be used on all types of wounds?
It's essential to consult a healthcare professional before using it, especially in severe or chronic cases.
Is there a difference between regular honey and manuka honey for wound care?
Yes, manuka honey has significantly higher antibacterial properties compared to regular honey.
What is medical-grade Manuka honey?
It's Manuka honey made into a wound care product. DermNet describes medical-grade honey as sterilised and laboratory-tested, and notes that medical-grade UMF honey is sterilised by gamma irradiation without losing its antibacterial activity. Only medical-grade honey is registered as a medical device for wound management (Journal of Community Nursing, 2014).
