UMF 10+ Active Manuka Honey is a highly researched product by Dr. Molan and his team at Waikato University in New Zealand.Manuka honey with the UMF property is gathered from the manuka tree flowers in only a few places in New Zealand. It is also evident that some areas of Manuka bushes do not produce honey with the UMF property every year, and the concentrations of UMF can vary from batch to batch and year to year. For this reason samples of every batch of UMF Manuka Honey are tested after the honey has been packed to ensure the presence of UMF.UMF 10+ brings unique antibacterial activity to you in a natural form that is perfectly safe.
