Manuka honey from New Zealand is the only honey that is
tested for its potency. The potency
levels of Manuka honey determine its effectiveness. Below a particular potency, it ceases to be
effective. If it’s overly potent, it
could cause discomfort and be very expensive.
Therefore, a medium potency is usually more desired and appropriate for
most applications.
The potency of Manuka honey is generally represented on
the front label of the jar by a number.
Some people feel that Manuka honey with a potency of 16 is best. In reality, between 10 and 16 is fine. The numbers can be compared to a solution
with the same percentage of phenol. For
example, Manuka honey 16+ is equivalent to a solution that is 16% phenol. Manuka honey 10+ or higher is considered
active.
Some brands may advertise that the numbers representing
the potency should be preceded by a particular three-letter acronym. These acronyms are just registered trademarks
and should not sway consumers into favoring them. What’s most important is that the laboratory
analysis is accurate and truthful.
Reputable brands don’t lie about these levels and the performance of
their honey reflects its quality.
The plus sign (+) following the number allows for some variation in the testing of the honey. For example, Manuka honey 16+ could test as 16.3, etc. It should not have a potency less than 16, but could be slightly higher.
