Manuka honey is from New Zealand and is from the Tea Tree species called Manuka. Due to scientific & marketing investment, it has proven strength levels of antibacterial properties. Raw honey is comparable to Manuka. It is historically proven that raw honey has been used for thousands of years for various illnesses.
Recent reports have shown that 1700 tonnes of Manuka honey are consumed by the UK each year but only 1600 tonnes are produced. And the UK is not the only country consuming Manuka. In addition, not all Manuka is raw and unpasteurised. That being said, real Manuka honey does have some good properties. We are sure with more scientific investment, raw honey will be known to be just as good.
