Beyond the flu shot: A closer look at the “alternatives”

Once again, it’s influenza season. The vaccine clinics are open, and the hysterical posts about the vaccine’s danger are appearing in social media. There’s familiarity to all of this, but also a big new change – at least in Canada, where I am. Pharmacists can now administer the vaccine. And it’s completely free to anyone in Ontario (where I am), so the barriers to obtaining the vaccine are pretty much eliminated. There’s no longer a need to drag your kids to their family doctor or line up at a public health clinic. Anyone can walk into a pharmacy, show their health card, and walk out minutes later, vaccinated.  It’s another enabling change that may help improve immunization rates, as uptake rates in the population remain modest.

This year’s flu season is (as of week 47) fairly quiet. Google Flu trends suggests a fairly typical picture, nothing like what we saw in 2009/10, the year of H1N1. My city’s influenza tracker reports only a dozen cases so far this season. Many of us will get our flu shot, continue with our lives, and not think about the flu until next season’s announcements. That’s the hope, anyway. Influenza can kill, and in its more virulent forms, is devastatingly deadly. The worst case scenario (so far) is almost unimaginable today. In 1918/19 an influenza pandemic killed 50 million people worldwide (5% of the population). So among public health professionals, that worry about the next wave is always present. Much has been written at this blog <plug>nicely compiled in the SBM ebook,</plug> on the efficacy and safety of the flu vaccine. In short, the vaccine is effective for both individual and population-level protection, but only modestly so, and its effectiveness varies based on its match with circulating strains. And despite widespread use for decades, there are frustrating limitations with the current vaccine beyond efficacy, including the need to repeat the shot annually. Someone said something about “going to battle with the army you have”. (I thought it was Crislip but he was quoting Rumsfeld.) The quote is apt. It’s not a perfect vaccine, but it does offer protection – if not directly to you, then indirectly to those at greater risk of infection. Hospitals and health facilities have been criticized for demanding health professionals either get the vaccine or wear a mask – and the arguments against vaccination are losing. But even the strongest advocates of influenza vaccine will acknowledge its limitations, which perhaps contributes to the understandable perception that there is more that could be done- beyond reasonable and effective precautions like handwashing and hygiene.

Oil of Oregano

Paradoxically, the less evidence that exists to support the use of of a treatment, the more passionate its supporters seem to be. I learned this early in my career as a pharmacist. One pharmacy I worked at did a steady business in essential oils. And king of the oils was oil of oregano. Not only were there several different brands of the basic oil, they were different forms, including capsules, creams and even nasal sprays. Not aware of any therapeutic benefits, I would ask customers what they were using it for. I rarely heard the same condition described: skin infections, athlete’s foot, head lice, colds, sore throats, “parasites”, “yeasts”, diabetes, allergies and ringworm were apparently no match against the judicious use of oregano oil. Intrigued, I took a closer look.

Long before our scientific understanding of bacteria and antimicrobials, infected wounds were packed with different products in an attempt to minimize the odour, and hopefully speed healing. It’s likely that someone happened upon a fragrant herb and discovered that it seemed to help treat wounds (or at least, cover some of the smell). Given there have been some amazing drugs with powerful effects that have emerged from natural products, it’s certainly plausible that oil of oregano could have biological and therapeutic effects. Oregano (Origanum vulgare) leaves contain a wide variety of chemical compounds, including leanolic acids, ursolic acids, and phenolic glycosides. Phenolic compounds make up to 71% of the oil. Carvacrol, thymol, cymene, and terpinine and are found in oregano leaves and do appear to have biological effects. It’s these chemicals that are proposed to be the parts with beneficial effects.

The claims made by one manufacturer are unambiguous:

Oreganol P73 is the most powerful germ killer with scientifically proven results against almost every virus, bacteria, parasite, and fungi. The complexity of the phytochemical matrix in Oreganol P73 possesses a broad spectrum of antimicrobial properties that are safe for prolonged use. The oil can be used topically and internally. Oreganol P73 is the medicine chest in a bottle, especially since it is proven never to harm the internal organs, even when used daily for health maintenance.

So if we accept the manufacturer’s claims at face value, there should be evidence demonstrating oregano oil is both safe and effective when used internally and externally. There is apparently also adequate long-term safety data to demonstrate that it can be safely used on a daily basis.
