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...

Do vitamins prevent cancer and heart disease?

It is a triumph of marketing over evidence that millions take supplements every day. There is no question we need vitamins in our diet to live. But do we need vitamin supplements? It’s not so clear. There is evidence that our diets, even in developed countries, can be deficient in some micronutrients. But there’s also a lack of evidence to demonstrate that...

New concerns about the safety and quality of herbal supplements

If there is one aspect of “alternative” medicine that both critics and fans should agree on, it’s that products should be manufactured to high standards. What’s on the label should accurately describe what’s in the bottle. Product quality standards are essential, whether you’re using herbs or drugs. And when it comes to ensuring the products we buy are of high quality, we’re...

Student Health Professionals and Attitudes about CAM

While I’m now two full decades out of pharmacy school, I am occasionally invited to return to give a lecture or facilitate a workshop. Pharmacy education has changed a lot since the 1990’s. For me, pharmacy was a Bachelor’s degree program you started right out of high school. Today, students must have a few years of university completed before they can apply...

Acetaminophen: Still the pain reliever you should trust?

Recently ProPublica and This American Life (TAL) released the results of an investigation into acetaminophen, the active ingredient in Tylenol. TAL devoted an entire episode to the issue, and ProPublica has published several stories on acetaminophen’s toxicity, how it can cause harm, and how it is regulated. The investigation summarizes the key “Takeaways” as follows: 150 Americans die per year from accidental...

A closer look at Dr. Oz’s 15 Superfoods

I’m sure I’m not the only health professional that bites their tongue whenever a patient starts a question with “I heard on Dr. Oz that…” More often than not, I have expectations to realign, and some assumptions to correct. I could easily devote all my posts to simply correcting  information presented on the Dr. Oz show. But given I’m blogging here biweekly,...

Food Allergies: Facts, Myths, and Pseudoscience

The price of life is eternal vigilance. If you have severe food allergies, that is your reality. Every day, every meal, every bite. Eating is an intrinsic and essential part of what we do and who we are, so the idea that our bodies can rebel violently to everyday foods can be difficult to believe. But it’s real, and the numbers of...

The Trojan Horse called Integrative Medicine arrives at another medical school

Medicine is a collaborative practice. Hospitals are the best example, where dozens of different health professionals work cooperatively, sharing responsibilities for patient care. Teamwork is essential, and that’s why health professionals obtain a large part of their education on the job, in teaching (academic) hospitals. The only way that all of these different professions are able to work together effectively is that...

The facts of the alternative medicine industry

People have been living on earth for about 250,000 years. For the past 5,000 healers have been trying to heal the sick. For all but the past 200, they haven’t been very good at it. – Dr. Paul Offit Twenty years is a long time in medicine. I celebrated my 20th pharmacy class reunion last weekend. Of course reunions are time to...

I’ve been prescribed an antibiotic. Should I take a probiotic?

We are not one organism, we are many organisms. And when we disturb the relationship with our symbiotic partners, we can suffer unpleasant and sometimes life-threatening consequences. One of the most fascinating areas of medical research is the study of how our bodies interact with the the various organisms that we carry around, on us and in us. A focus is the...
