Manuka honey is a type of honey which has a high value in the marketplace because it has a special flavour and other medicinal attributes due to it being predominantly from New Zealand where beekeepers set up their hives in wild uncultivated areas in which Manuka bushes grow. While it is true that all honeys have some medicinal value, active manuka honey containing the Unique Manuka Factor (UMF) has been proven to have a higher antibacterial activity than other tested honeys.
Manuka honey has even been used to apply to the skin directly to help with various ailments, but it is recommended that one uses a UMF value of 15 or higher.
