I often read claims about honey that I find somewhat dubious, to say the least. Following a comment (see below) from Manuka Honey Health (http://www.manukahoneyhealth.co.uk/), I thought it might be jolly to find out more about manuka.
Manuka is the common name for Leptospermum scoparium, or the tea tree to you and me (see http://en.wikipedia.org/wiki/Leptospermum_scoparium), as in tea tree oil, tea tree shampoo, tea tree tea (OK, I made that one up).
There is no evidence for manuka honey or any monofloral honey (rape? heather?) being better for you, in any way, than multifloral honey. If there is evidence, let's see it.
One last thought: honey is, in so many words, bee-sick, or perhaps bee-spit.
