I've come across a topic only mentioned on this board once before - Manuka Honey! The manuka bush is native to New Zealand, and the only other place it grows is on the Tregothnan estate in Cornwall. I heard this on R4 this morning, although there is plenty of info about it on the web. Tregothnan manuka honey is sold exclusively through Fortnum & Masons, but lesser mortals can get manuka honey from Holland and Barrett, etc.
Here's an article from 2009:
The benefits of Manuka honey
Can Zealand's much-hyped 'superfood' really heal, both inside and out?
By Alice Hart-Davis 7:00AM BST 10 Aug 2009
When a good idea comes along, particularly in the health and wellbeing field, people often pick up on its essence rather than its detail.
Take the "five a day" edict, for example. Everyone knows that it means you should eat five portions of fruit and veg a day, but most of us get a bit hazy on the detail. If you have a huge portion, does it count as two? (No.) And potatoes are a vegetable, aren't they, so do they count? (Again, no.)
It's even more confusing when you take a newer idea like the benefits of Manuka honey, which has become a much-hyped superfood. But what does it do, exactly?
A recent survey of people who bought the stuff showed that 58 per cent of them believed Manuka honey to be better than ordinary honey, but they didn't know why. In addition, 70 per cent of them didn't know what the UMF (Unique Manuka Factor) number on the front of the pots meant.
Manuka honey has long had a reputation as a "healing" honey and, because it comes from bees that have been busy pollinating the Manuka trees that grow almost exclusively in the East Cape region of New Zealand, it has rarity value. This makes it expensive.
Honey has long been seen as one of health's "superfoods" (I use the inverted commas as no food is "super" in isolation), offering a number of benefits. Local honey containing local pollen can help reduce the symptoms of hay fever.
Most honeys contain a naturally occurring active agent, which is thought to support good health but is easily destroyed when exposed to heat and light. Manuka honey contains an extra, naturally occurring active ingredient, which makes it distinct from other honeys. This additional component is stable and doesn't lose its potency when exposed to heat, light or dilution. Its special quality is known as UMF and the higher the UMF, the more potent the honey and its powers (aficionados reckon that you need a UMF of 10 or higher for the honey to be properly effective).
It has antiviral and antibacterial actions, which is a good excuse for scoffing the stuff neat at the first sign of a cold or sore throat.
Most people who buy Manuka honey simply put it on their toast or in their tea, but where it really comes into its own is in treating wounds. In New Zealand, it has long been used in this way and studied extensively. Now, the NHS is doing the same.
According to doctors, Manuka honey's high sugar content creates a waterless environment in which the bacteria that are infecting a wound are unable to survive. Also, thanks to the presence of an enzyme called glucose oxidase, it is acidic, which apparently adds to its unique antibacterial properties.
It seems a shame to confine such a wonder substance to the boring business of healing wounds – hence the proliferation of skincare products containing Manuka honey. Will they really help heal your skin and enhance natural cell renewal better than their non-UMF-bearing competitors? It's a sweet idea, but one that you might have to take with a pinch of salt.

Manuka honey 'could help fight superbugs'
By Michelle Roberts, Health reporter, BBC News
Manuka honey could be used to combat some of the most hard-to-treat infections that are resistant to powerful antibiotics, scientists say.
Lab experiments show it can clear bacteria found in festering wounds and contaminated hospital surfaces.
It works by breaking down the defences bacteria use against antibiotics, making it useful in treating superbug infections such as MRSA.
The results were presented at a Society for General Microbiology meeting.
Professor Rose Cooper from the University of Wales Institute Cardiff found a variety of honey from bees foraging on manuka trees in New Zealand proved effective.
A specially filtered version of this honey, with impurities removed, is already used in modern licensed wound-care products around the world.
Indeed, people have known for centuries about honey's antiseptic powers.
The researchers wanted to gain a better understanding of this honey's bacteria-fighting properties and to see if it might help tackle some of the most stubborn infections encountered in our hospitals.
Professor Cooper's work with two common types of bacteria - streptococci and pseudomonads - revealed that manuka honey can deter the attachment of bacteria to tissue, which is an essential step in the initiation of acute infections.
Stopping attachment also blocks the formation of biofilms, which can protect bacteria from antibiotics and allow them to cause persistent infections.
The latest lab work showed that the honey can make MRSA more sensitive to antibiotics such as oxacillin - effectively reversing antibiotic resistance.
Professor Cooper said: "This indicates that existing antibiotics may be more effective against drug-resistant infections if used in combination with manuka honey.
"What we need to do now is look at more combinations with antibiotics and do some clinical work in patients.
"It could be applied topically to wounds and used in combination with antibiotics to treat resistant infections."
But she warned people not to try the same at home with honey bought from the supermarket. "Not only is it messy, it wouldn't be advisable. We have been using medical grade honey, not the stuff you buy in shops."

Ginando:
On the recommendation of a friend, and after months of steroidal creams which did nothing, I recently tried applying Manuka Honey to a small patch of irritated skin on my hand. I applied it as a poultice which I leave on overnight, and after only a few days it has virtually disappeared. I am very impressed as this is the first time I have ever tried an 'alternative' therapy.
