The Aussie Difference
Manuka honey comes from the flowers of the Leptospermum scoparium tree, native to New Zealand (with some small stands also found in Australia).
While Jellybush honey is derived from, predominantly, Leptospermum polygalifolium, a small shrub-like tree found extensively throughout the eastern coastal ranges of Australia.
So, while of the same genus (Leptospermum), they are slightly different species. What many may not know is that honey from Jellybush flowers generally contains higher concentrations of the main bio-active compound, methylglyoxal (MGO), than its Kiwi counterpart.
