Better to prevent now than to regret later

Melipona Honey is twice as nutritious as ordinary honey. Melipona bees feed on native plants whose flowers, rich in alkaloids and flavonoids, give the Melipona Honey its highly medicinal properties.

Honey is appreciated the world over as one of nature’s most delicious foods, but did you know it may have potent anti-flu properties as well?

A study published in the Archives of Medical Research, titled “Anti-Influenza Viral Effects of Honey In Vitro: Potent High Activity of Honey,” reveals that honey may actually provide a natural drug alternative to anti-flu drugs, but without the notorious side effects associated with this drug class.

The study tested a commonly researched H1N1 influenza strain by infecting Madine-Darby canine kidney (MDCK) cells with the virus and then exposing them to various forms of honey.

Potent AntiViral Properties

The anti-influenza effects of the honey samples were evaluated by growing MDCK cells in 48-well plates and infecting them with influenza virus in the presence of two-fold serially diluted honey samples. Two days after infection, the cells were fixed and stained in order to ascertain the degree to which they prevented the cytopathic effect (that is, the degree to which infection caused the cells to die and detach from the plate) of influenza virus.

All tested honey samples suppressed viral infectivity in a dose-dependent manner, indicating their antiviral activity.

The study also tested whether honey is able to directly inhibit influenza virus growth through what is known as the plaque inhibition assay, as determined through the following four methods:

  • Pretreating the cells, adding honey to the cells for one hour and subsequently washing them out before viral infection.
  • Pretreating the virus, mixing honey with influenza virus suspension for one hour before viral infection  
  • Treating cells during viral infection, adding honey during virus adsorption for one hour and subsequently washed out
  • Treating cells after viral infection, adding honey to the agarose gels

The most potent effect was exhibited with pretreatment of the virus itself, indicating honey has potent virus-killing properties. Moderate reductions in plaque numbers were observed in cells treated with the honey during and after infection. The only method that did not demonstrate a growth inhibition was the pretreatment of cells.

Synergistic Effect With Conventional Drugs

The study also looked at honey synergistic properties in combination with conventional anti-viral drugs in the neuraminidase inhibitor class, such as Relenza (zanamivir) and Tamiflu (oseltamivir phosphate).

The researchers said, “A combined use of synergistically active anti-viral compounds that have different mechanisms of action may provide advantages over single-agent treatments.”

The plaque-inhibition assay protocol was reproduced, but this time the drugs were added to the honey mixture, with the result that honey significantly increased the antiviral effectiveness of both drug compounds.

How Honey Works and Further Implications

In the discussion section of the paper, the researchers pointed out that the antiviral activities of the honeys tested are likely attributable in some part to the presence of a wide range of phytochemicals contained within them, especially phenolic acids and flavonoids.

Independent research has already confirmed the anti-microbial properties of rutin and chrysin, which are found in relevant concentrations in most honeys. Honey, on the other hand, contains a compound known as methylglyoxal, which is found at concentrations 20 to 160 times higher than in any other honey yet tested and which has already been verified to have antiviral properties in foot-and-mouth disease virus.

The study authors commented that we live in a time when there is an urgent need for new anti-influenza medicines. They pointed out that, in Japan, Tamiflu-resistant flu increased from 2.6 percent in 2007–2008 to over 99 percent in 2008–2009, illustrating a disturbing trend of increased drug resistance.

The authors point out that “because compounds or plant extracts that exhibit virucidal activity have broad spectrum, it is possible that the virucidal activity of honey is effective against H5N1 and H7N9 viruses,” which are considered highly pathogenic viruses.

The researchers concluded their study on a promising note:

“In conclusion, the results obtained showed that honey, in general, has potent inhibitory activity against influenza virus, demonstrating a possible medicinal value. Further investigations are required to identify the active antiviral components in honey and to determine its synergistic effects with known antiviral drugs.”

Natural Alternatives Abound

This study is one of hundreds in existence today on the potential role of natural compounds in preventing infection by influenza. A few highlighted interventions include the following:

Vitamin D: Sunlight exposure is of fundamental importance in supporting natural immunity against influenza. In fact, according to the seasonal stimulus hypothesis, seasonal influenza may be triggered each year during the fall and winter months (especially in higher and lower latitudes) due to lower sunlight availability and a subsequent crash in immune factors dependent on sunlight-induced vitamin D production. To this point, a 2010 study found that the simple addition of a vitamin D supplement is effective in preventing seasonal influenza A in schoolchildren, reducing risk by 59 percent. There is also evidence that lower solar ultraviolet-B radiation (and vitamin D) levels were significant contributing factors in reducing case-fatality rates from the 1918–1919 influenza pandemic in the Unites States.

Elberberry: Something as simple as a purple berry may improve your chances of both preventing and fighting off influenza. A 2004 study found that elderberry was a safe and effective treatment for both influenza A and B strains, improving recovery time from influenza in 93.3 percent of the elderberry treated group within two days, and in 91.7 percent of the control group within six days. Another 2004 study found elderberry relieved symptoms of influenza four days earlier on average than those receiving a placebo. Cell research has also demonstrated that elderberry flavonoids bind to and prevent H1N1 infection.

Green Tea: Drinking green tea has been found to reduce the incidence of influenza infection in Japanese school children. It has also been found safe and effective in healthy adults (aged 18–70) for preventing flu symptoms and for enhancing T cell function. Green tea has also been found to contain compounds that inhibit the two primary molecular means by which influenza gains entry into the cell to infect it.
