Honey has been used for thousands of years for wound healing and it is known to have anti-microbial properties. What is the evidence that manuka honey does actually improve wound healing?
Tan et al; 2009
Tan et al (1) have shown that manuka honey and Malaysian tualang honey have a range of antibacterial properties against a number of bacteria found in wounds. However, this was an ‘in vitro’ study that did not look at clinical activity (the effects of the honey on actual symptoms in patients).
But studies have been carried out that show that honey (‘medihoney’ and manuka honey) can have a beneficial clinical effect in the treatment of leg ulcers, infected wounds and burns on actual patients.
Molan (2), in a review published in 2006 reported a total of 22 different clinical studies (17 of them fully randomized controlled studies) involving over 2000 patients, that have demonstrated a positive clinical effect for the use of honey to assist wound healing.
However, while some fully randomized studies show a beneficial effect, there are others which appear to suggest that it seems to depend on the precise organism associated with the infection.
Gethin and Cowman; 2008
Gethin and Cowman (3) showed a significantly better reduction of MRSA in leg ulcers by use of manuka honey compared to the usual treatment (hydrogel). Other studies also indicate a positive effect of Manuka Honey on MRSA.
However, in the same study they showed that manuka honey was not as good at reducing Pseudomonas infection.
Karamatos et al; 2014
Karamatos et al (4) showed a significant clinical advantage to using manuka honey impregnated dressings for the treatment of diabetic foot ulcers when compared to their normal treatment using conventional dressings.
Robson et al; 2009
Robson et al (5) showed a significantly better clinical outcome for honey dressings in wounds compared to normal dressings.
Other research investigating manuka honey & wound healing have shown
Jull et al; 2007
Jull et al (6) were unable to demonstrate any significant difference in the rates of leg ulcer healing when comparing use of honey impregnated dressings and the normal dressings use in the units involved in the study. In actual fact, the ‘honey’ treatment group performed had better healing than the usual treatment group, but the researchers note that the difference was not significant.
The study states:
Johnson et al; 2014
Johnson et al in The Lancet (7) showed no beneficial effect of using ‘medical honey’ to prevent catheter –related infections in peritoneal dialysis over their normal therapy (mupiracin). Unfortunately,11.6% of the group using honey experienced some local infections, and there was an increased risk of peritonitis in part of the ‘honey group’ which had diabetes.
Bardy et al; 2011
Bardy et al (8) in the British Journal of Maxillofacial Surgery investigated the effect of manuka honey in radiotherapy-induced mucositis (that is painful inflammation of the mouth caused by radiotherapy to the head and neck.
They concluded that active manuka honey did not improve mucositis.
There have also been a number of individual case studies reported in the medical press:
Natarajan et al (9) reported a single patient case study in which manuka honey eradicated a MRSA leg infection. Other studies have found manuka honey to be effective against MRSA, so perhaps it’s no surprise if manuka honey is effective in wounds where MRSA is a key factor.
Visavadia et al (10) report successfully using manuka honey impregnated dressings on their maxillofacial unit.
Blaser et al; 2007
Blaser et al (11) reported full wound healing in seven patients with MRSA infected wounds – infections that had previously not responded to treatment with antibiotics.
Robson & Cooper; 2009
Robson & Cooper (12) report successful use of manuka honey in patients with damaged skin due to radiotherapy. The authors reported complete healing of damaged skin areas.
