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
Medical marijuana. It’s promoted as a seeming panacea that can cure whatever ails you. In particular, it's touted, primarily in the form of cannabis oil extract, as a cure for cancer that "they" don't want you to know about. While there are potentially useful medicinal compounds in marijuana, in general the medical marijuana movement vastly oversells the promise. While some cannabinoids do...
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
Medical marijuana. It's promoted as a seeming panacea that can cure whatever ails you. While there are potentially useful medicinal compounds in marijuana, in general the medical marijuana movement vastly oversells the promise. The truth is far more prosaic and nuanced.
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...
