Flora Mānuka Honey is licensed by the Unique Mānuka Factor Honey Association™ in New Zealand. This is an internationally recognized, third-party verification system that ensures the identity, potency and quality of mānuka honey. UMF™-certified products have been tested for three signature compounds that are all needed to ensure the honey is real mānuka honey made from Leptospermum scoparium flowers: Leptosperin, DHA (Dihydroxyacetone) and Methylglyoxal (MGO). The higher the UMF™ grading number on the product, the higher the concentration of signature compounds found in mānuka honey. UMF™ is a quality trademark. The UMF™ grading system appraises natural markers found in Mānuka honey and assures purity and quality. For more information, please visit www.umf.org.nz.
