Is manuka honey a wonder cure or another overrated holistic drug?

I was talking to a friend recently about an expensive honey from New Zealand. It’s called manuka honey and it comes from the flowers of the manuka tree. Manuka trees are commonly called New Zealand tea trees and are in the myrtle family.

Raw honey is naturally antimicrobial and has long been used in human and veterinary medicine. My father-in-law used it to treat freshly dehorned cattle. I was shocked when I first saw it.

He removed the horns, which many would consider a brutal process. It really isn’t, because horn removal lessens injury when animals are kept in close quarters.

After removing the horns, he tied off bleeding blood vessels and cleaned the area. Finally, he coated the wound with a thick layer of honey. I can’t recall any surgical sites becoming infected.

I don’t know how much he knew about microbiology. I think he was more concerned about keeping flies from laying eggs. They would die in the sticky honey.

He used local raw honey because it was available and cheap. Raw honey is important since a large percentage of honey in stores has been processed and blended to such a degree that most antimicrobial properties have been lost.

Manuka honey is not cheap. Some medical grade stuff can sell for well over a hundred dollars for an eight-ounce jar. This honey has a high MGO content. MGO stands for methylglyoxal, which is much higher in manuka honey than any other types. This chemical has strong antimicrobial properties.

Pollen from the manuka plant is high in methylglyoxal. However, there is considerable variability. In addition, much honey is mixed from other pollen sources.

Manuka honey that is marketed as medicinal quality is graded on its antibacterial strength called its Unique Manuka Factor (UMF). Values of 15 or greater are much more valuable for medicinal use. Price is much greater, too.

Manuka honey is used to treat acid reflux disease and other digestive system problems like stomach ulcers and irritable bowel syndrome. It also is used to treat tooth decay and gingivitis and it also has been used to combat strep throat.

Not all use is internal. Manuka honey is employed topically to treat skin infections like eczema and acne. Research even shows its effectiveness in controlling MRSA and other serious staph infections.

Burn and wound treatment are other topical uses. Numerous sources also indicate it helps with skin ulcers caused by diabetes. Even ear infections have been treated with Manuka honey. Honeys with higher UMF levels are most often used topically.

Like all honey, manuka is high in sugar and could be a problem for diabetics when consumed internally. In addition, it could pose problems for folks allergic to honey, even with topical treatment.

There are hundreds of articles about manuka honey on the internet. Some promise such superlative results that they are too much for my inner skepticism. Still, due to the sheer volume of research, the product must have some merit. I still suggest contacting your medical professional before jumping headlong into the manuka phenomenon.

About tedmanzer

I grew up in Old Town Maine and got a B.S. at the University of Maine in Plant Sciences/ minor in Botany. From there I moved to West Virginia and earned a M.S. in Agronomy at WVU. I also met my wife there. She grew up in rural WV as the daughter of tenant farmers who raised cattle and hogs. Their lifestyle at times was one of subsistence and I learned a lot from them. I've always been a foraging buff, but combining my formal botanical knowledge with their practical 'Foxfire-type' background opened up my eyes a little more. I recently retired from teaching high school agriculture after 25 years teaching with my wife. Until recently I wrote a weekly nature/foraging column for the local paper ( I also have written several Christian nature/adventure novels that can be purchased on Amazon in Kindle format. One is a five book family saga I call the 'Forgotten Virtues' series. In the first book, Never Alone (presently out of print), a young boy comes of age after his father dies in a plane crash, and he has to make it alone. The second book, Strange Courage, takes Carl from his High School graduation to his recovery from a nasty divorce. The third book, Second Chances, takes Carl from his ex-wife's death and the custody of his son to his heroic death at age 59. The fourth book, Promises Kept, depicts how his grandchildren react and adjust to his death (this one is not yet published). In the final book, Grandfather's Way, his youngest and most timid granddaughter emerges from the shadow of her overachieving family and accomplishes more in four months than most do in a lifetime. I use many foraging references with a lot of the plants I profile in these articles in those books. I also wrote a romance novel titled Virginia. It is available on Amazon and is a different type of romance from a man's perspective.

    That is fascinating, and I have heard about how some honey benefits from the flowers who provided the pollen. I have also heard about ‘mad honey’ that is made from rhododendron pollen. That sort of concerns me since we grow rhododendrons!
