K2: The Vitamin, Not the Mountain

Science is complicated. Simple concepts that appear at first to be obviously true or untrue usually turn out to be more nuanced than we thought. Newtonian physics was taken as “the truth” until we learned in the 20th century that it didn’t apply on cosmological or subatomic scales. Medicine and human physiology are more complicated than most people realize or want to...

Medical marijuana as the new herbalism, part 2: Cannabis does not cure cancer

About a month ago, I finally wrote the post I had been promising to write for months before about medical marijuana. At the time, I also promised that there would be follow-up posts. Like Dug the Dog seeing a squirrel, I kept running into other topics that kept me from revisiting the topic. However, over the past couple of weeks, the New...

Chiropractic scope of practice includes . . . well, you won’t believe it

Ladies, how would you like a chiropractor to deliver your baby? How about perform your annual well-woman exams, such as breast exam, bi-manual pelvic exam, speculum exam, recto-vaginal exam and Pap smear? Sound out of their league? I thought so too. Way out. But, in some parts of the U.S., the law allows chiropractors to do all of these things and a...

Drinkable Sunscreen Snakeoil

In May, prompted by an uncritical article in the Daily Mail, the internet was buzzing about a company that was offering drinkable sunscreen. This is one of those game-changer health products that immediately garners a great deal of attention. At first the claim seems extraordinary, but it is not impossible. It is theoretically possible to drink a substance that becomes deposited in...

Medical marijuana as the new herbalism, part 1: Science versus the politics of weed in New York and beyond

A while ago, I wrote about how the Cleveland Clinic had recently opened a clinic that dispensed herbal medicine according to traditional Chinese medicine (TCM) practice. As regular readers of the SBM blog might expect, I was not particularly impressed or approving of this particular bit of infiltration of quackademic medicine into a major academic medical center, particularly given some of the...

John Oliver skewers Dr. Oz for his hawking of diet supplements

As regular readers of this blog know, Dr. Mehmet Oz had a very, very bad day last week, in which he received a major tongue lashing from Senator Claire McCaskill (D-MO) for the scientifically unsupported and irresponsible hyperbole he dishes out day after day on his syndicated daytime television show. Personally, I was tempted to pile on myself, but had to content...

Dr. Oz and the Terrible, Horrible, No Good, Very Bad Day

Dr. Mehmet Oz is one of the most well-known, and possibly the most influential medical doctor in America. The Dr. Oz Show is broadcast in 118 countries and reaches over 3 million viewers in the USA alone. When Oz profiles a product or supplement on his show, sales explode – it’s called “The Dr. Oz Effect”. Regrettably, Oz routinely and consistently gives...

Turmeric: Tasty in Curry, Questionable as Medicine

A correspondent asked me to look into the science behind the health claims for turmeric. He had encountered medical professionals “trying to pass turmeric as some sort of magical herb to cure us from the ‘post-industrial chemical apocalypse.’” It is recommended by the usual promoters of CAM: Oz, Weil, Mercola, and the Health Ranger (who conveniently sells his own superior product, Turmeric...

Macular Degeneration and AREDS 2 Supplements

Four years ago I wrote about the premature marketing of a diet supplement for macular degeneration before the results of a trial to test it were available. Now that we know the results of that trial, a follow-up post is in order. Age-related macular degeneration (AMD) is a leading cause of blindness. The incidence increases with age; it affects 10% of people...

VacciShield: Pixie dust for an imaginary threat

I know by now I shouldn’t be, but I am still amazed by how readily so many people buy into the seemingly endless array of bogus sCAM nostrums. Many are marketed and hawked for the treatment or prevention of diseases that are poorly managed by science-based medicine. There are countless examples of dietary supplements that are purported to effectively treat back and...
