The market for Manuka honey has recently exploded, thanks to the perceived benefits of its natural antibacterial properties. But what evidence is there to support the claims?
In this article, we explore what Manuka honey is, what its properties are, and how it differs from other types of honey.
We also look at the evidence available to assess whether Manuka honey really is the next great superfood.

Historical use of honey
Honey has been used to treat wounds since ancient times, as detailed in a document dating back to 1392. It was believed to help in the fight against infection, but the practice fell out of favor with the advent of antibiotics.
As we face the challenge of a growing worldwide resistance to antibiotics, scientists are examining the properties and potential of honey.
Qualities of Manuka honey
The leaves of the Manuka tree, also known as a tea tree, have been known for centuries among the indigenous tribes of New Zealand and southern Australia for their healing powers.
Bees that collect nectar from this tree make Manuka honey, which harbors some of healing properties.
All honey contains antimicrobial properties, but Manuka honey also contains non-hydrogen peroxide, which gives it an even greater antibacterial power.
Some studies have found Manuka honey can also help to boost production of the growth factors white blood cells need to fight infection and to heal tissue.
Manuka honey contains a number of natural chemicals that make it different:
- Methylglyoxal (MGO): This has been shown to be effective against several bacteria, including Proteumirabilis and Enterobacter cloacae.
- Dihydroxyacetone (DHA): This is found in the nectar of Manuka flowers and converts into MGO during the honey production process.
- Leptosperin: This is a naturally occurring chemical found in the nectar of Manuka plants and a few close relatives.
Manuka honey and wound care
Medical grade honey, used by healthcare professionals as part of a wound dressing, can help some kinds of wounds to heal.
Experts believe that because Manuka honey has added antibacterial and healing properties, it may be even more effective. At the moment, however, there is little evidence to support the theory.
