Manuka Honey


Dr. Peter Molan of Waikato University in New Zealand started a research team over 20 years ago with the main purpose of finding the difference between regular honey and a special type of Manuka Honey considered by many to have therapeutic qualities.

In addition to Hydrogen Peroxide found in all honeys, Dr. Molan and his research team have discovered, in some strains of Manuka Honey a secondary ingredient with extreme antibacterial properties and resistance to many environmental variations.

He determined that this factor gives Manuka Honey a larger range of uses and effectiveness in healing multiple affections. This factor was named UMF® .

What is UMF®

UMF stands for Unique Manuka Factor, a registered name given by Dr. Peter Molan and his research team at the Honey Research Unit at Waikato University in New Zealand. Dr. Molan discovered that not all Manuka Honey contains the secondary active ingredient with higher antibiotic properties.

The UMF® Guarantee

The UMF® is an industry registered standard that indicates Manuka Honey with special UMF® properties. The name UMF® on a Manuka Honey label, guarantees consumers that the honey purchased has at least the level of activity indicated.
Only Manuka Honey tested and packed in New Zealand can qualify for UMF® and every batch is tested after the Manuka Honey is packed in processing facilities. In order to qualify for the appellative UMF®, Manuka Honey must be packed and tested in New Zealand.

What is the difference between UMF® Ratings

The number that follows UMF® represents the antibacterial strength of the Manuka Honey. Minimum UMF® level accepted is 10+ and any Manuka Honey with UMF® 16+ and higher is known to have high levels of antibiotic, antiseptic and antiviral activities.

How is Manuka Honey tested for UMF®

Samples of Manuka Honey are being sent to a special laboratory where, using techniques laid down by the Honey Research Unit at Waikato University; honey is tested for its antibacterial property.
Two kinds of tests are conducted:

  1. Total Activity Rating which measure the total level of activity due to the hydrogen peroxide present in all honeys. Total Activity level does not include the UMF® activity.
  2. UMF® Activity Rating which measures the non hydrogen peroxide antibacterial level of the Manuka Honey. This test is conducted by adding a catalase to the sample of Manuka Honey with the purpose of removing any traces of Hydrogen Peroxide. All that is measured after the removal of Hydrogen Peroxide is the level of UMF®.

How does the level of UMF® influences the antibacterial qualities of Manuka Honey?

Please note that UMF® below 5+ is not detected.
Honey with UMF® 5+ to UMF® 9+ is not recommended for therapeutic use but it is a great table honey.
UMF® levels between 10+ and 15+ are recognized and endorsed by the Honey Research Unit.
Manuka Honey with UMF® 16+ and above is considered to have very high levels of antibacterial activity and it is recommended in homeopathic treatments.

UMF® Research Conclusions

One of the most important findings of the researches conducted on UMF®, is that no bacteria or virus has been found resistant to the high levels of UMF®.

  1. Studies show that high UMF® properties are effective against several kinds of bacteria. Some bacteria like helicobacter pylori have developed a high resistance to many antibiotics. This bacterium is known to cause most stomach ulcers and duodenal ulcers.

  2. Active UMF® Manuka Honey is proven to have an impact in treating wounds infected with Staphylococcus aureus or MRSA, also called the super-bug for its high level of immunity to most available antibiotics.

  3. Active UMF® Manuka Honey is proven to penetrate deep into skin tissue and body fat effecting deep-seated infections. Research shows that UMF® Manuka Honey has been able to penetrate 1 cm of pig skin and fat in 12 hours.

  4. Research shows that a powerful strait of Escherichia coli has been greatly affected by Manuka Honey with high levels of UMF® activity.

  5. Streptococcus pyogenes, the virus that causes sore throats has also been immune to many classic antibiotic drugs and scientific studies have proved that the high levels of UMF® Manuka Honey is effective in treating this virus.

  6. Research also shows that unlike Hydrogen Peroxide, UMF® is a very stable ingredient being able to remain active even in environments with high heat, humidity, light and body fluids. The PH level of acidity in most honey could be sufficient to inhibit the growth of many bacteria, however in contact with body fluids this quality may be neutralized. The UMF® factor is stable in moisture making it a suitable antidote to many bacterial and viral infections.

  7. The phytochemical in UMF® Manuka Honey is not reliant on Oxygen to be effective unlike the glucose oxidase enzyme which produces hydrogen peroxide. Active UMF® Manuka Honey will remain active even inside wounds or covered by medicinal gauze.

How is UMF® Manuka Honey different than other honeys?

Manuka Honey is produced by bees who gather nectar from the flowers of Manuka Tree (Leptospermum Scoparium). Manuka tree or Manuka Bush grows wildly on undeveloped lands and hills of New Zealand. Not all honey produced from Manuka Flowers has UMF® activity detected.

Some areas of Manuka Bushes do not produce the same kind of honey every year. For this reason every batch of Manuka Honey is tested after packing the honey in jars to ensure and preserve its UMF® properties.

The presence of Hydrogen Peroxide in all honeys is the cause of an enzyme added to the honey by the bees unlike the presence of UMF® which is a phytochemical-derived property (caused by the nectar of the Manuka Flower).

Researchers have yet to prove whether the UMF® factor comes from a subspecies of Manuka Bush or it is caused by some environmental factors such as the quality of the soil. It is also impossible to predict the level of UMF® in Active Manuka Honey from year to year. Every batch is tested and labeled after the honey has been packaged.

The information on this website is not intended to replace medical advise. We do not recommend people to stop taking their prescribed medications or to stop visiting their physician.
Our intention is to increase awareness about the potential healing qualities of the Active Manuka Honey and to make it available to people who are interested in homeopathic ways to regard diseases and who wish to experience the benefits of a product that received the attention of many international researchers.
Please seek medical advise if symptoms persist.
