Manuka Honey has antimicrobial properties, making it antibacterial, antifungal and antiviral as well as having anti-inflammatory, antioxidant and immune-modulatory properties. These properties make the honey great for digestion, immune function and skin-care. Containing over 2,000 individual natural compounds, which is 20 times more than some conventional honeys.
Both Australia and New Zealand produce this incredible honey. They both boast the high levels of MGO. In New Zealand, to be able to call the product manuka honey, it can only be derived from the Leptospermum scoparium. In Australia, it is derived from multiple species of the Leptospermum plant as the plants often grow side by side. So the difference stems from the plants the honey is made. The Australian Manuka honey is slightly darker than New Zealand. Both have high antibacterial properties. It seems like the biggest problem is that New Zealand would like to have sole rights to sell the product in China, where a single bottle can be sold for many hundreds of dollars.
