What makes Manuka Honey So Special
For thousands of year honey has been used both orally and topically as a natural remedy. All honey has the enzyme glucose oxidase – which releases hydrogen peroxide. The enzyme is secreted into the honey by the bee when regurgitating nectar from the floral source. As a result all honeys have hydrogen peroxide present. The native New Zealand Manuka bush (Leptospermum Scoparium) is known to contain a special property that distinguishes it from all other honeys.
These unique properties were discovered by New Zealand scientist Prof Peter Molan, who began his honey investigation in 1982. The numbering system 10+ 16+ 20+ 25+ was used to show the antibacterial efficacy of the honey when applied topically – 5+ was added later to show honey with some Manuka in it. This level does not have significant antibacterial strength.
Why you need the right sort of activity in Manuka Honey.
