Five Reasons Why Honey Heals

Honey is good, natural "medicine" for everyone - inside and out. So take it daily or rub it on and treat your body well and bee healthy...

Honey’s ‘healing powers’ can be summarised into 5 main ingredients or activities of the components of honey

Scientific American, 2012, March 21

Hydrogen peroxide – Honey contains an enzyme called glucose oxidase which breaks down glucose sugars and generates hydrogen peroxide, a kind of bleach, when there is free water available. In case you missed the antimicrobial component it was friggin BLEACH IN YOUR HONEY. I can feel you wondering why bees would bleach their own food supply and it turns out that is very simple. Any available water can cause the honey to spoil so the presence of glucose oxidase in the honey is an inbuilt anti-spoiling mechanism, pretty smart huh?

Sugar – The hydrogen peroxide control mechanism is a back up as very little free water exists in honey. The lack of free water is due to the vast amount of sugar dissolved into honey which gives it a low water activity. This essentially means that honey is more likely to take up water from its surroundings than have water removed from it and if you are a micro-organism it makes it very difficult to survive.

Methylglyoxal or MGO – This compound is an incredibly interesting and powerful antibacterial compound but, it is only found in certain natural honeys (Manuka honey from New Zealand) although it can be made in artificial greenhouses as well. This is the stuff that is making honey a potentially very useful topical salve (with the possibility of other forms of treatment being considered) in medical honey treatments such as MediHoney.

Bee Defensin 1 – Bee Defensin is an antimicrobial peptide (AMP) that for a long time was thought to be exclusively found in the Royal Jelly (The food worker bees make for potential Queen larve). But fairly recent discoveries have found it in the honey, but more on AMPs in a second.

Acidity – Finally, honey is fairly acidic and remains so even when diluted holding a pH of approximately 3.5. Nothing that likes eating you particularly likes living in acid so this property is very important.

No single property is more important than the others and the multifactorial nature of honey’s activities is probably the key to its amazing antimicrobial nature. Having said this, Bee Defensin 1 and other identified AMPs in honey such as Apidaecin may have much more involved roles that are only recently being uncovered...

Interestingly,apidaecins seem to also have the ability to alter the host immune system bymodifying chemotaxis (movement of cells in the immune system), apoptosis(induced cell death), cytokine/chemokine production (the production ofsignalling chemicals which direct the immune response), antigen presentationand the Th1/Th2 balance (whether you fight the nasty with B cells or T cells).

In mostcases the ability of apidaecins (and their homologues) to modulate the immunesystem has been done in the the organism the AMP was originally recovered frombut some recent work sugests the potential for insect apidaecin to have acrossover effect on a mammalian system. While apidaecin is insect derived itappears to be sufficiently similar in shape to human AMPs that it can interactwith and modify the activity of our immune system. When macrophages inparticular were incubated with apidaecin they started pumping out chemokinesand cytokines that promote increased antimicrobial activity in these cells...

While onlypreliminary, it seems honey and its various components might have more secretsto unveil which will further develop our understanding of the anti-microbialnature of this environmental product and at the same time its pro-immuneresponses elicited when we use it.
