Dr. Ian Gawler, a veterinarian, suffered from osteogenic sarcoma (a form of bone cancer) of the right leg when he was 24 in 1975. Treatment of the cancer required amputation of the right leg. After completing treatment he was found to have lumps in his groin. His oncologist at the time was confident this was local spread from the original cancer, which is highly aggressive. Gawler later developed lung and other lesions as well, and was given 6 months to live due to his metastatic disease.
Gawler decided to embark on an alternative treatment regimen, involving coffee enemas, a vegetarian diet, and meditation. Eventually he was completely cured of his terminal metastatic cancer. He has since become Australia’s most famous cancer survivor, promoting his alternative approach to cancer treatment, has published five books, and now runs the Gawler Foundation.
At least, that is the story he believes. There is one major problem with this medical tale, however – while the original cancer was confirmed by biopsy, the subsequent lesions were not. His oncologist at the time, Dr. John Doyle, assumed the new lesions were metastatic disease and never performed a biopsy. It was highly probable Read more »

Vitamins, herbs and other dietary supplements are sold as natural alternatives to pharmaceuticals and many people turn to them in an attempt to improve their health. Others seek supplements to lose weight or after hearing that they can help with serious medical conditions. These products are now used at least monthly by more than half of all Americans—and their production, marketing and sales have become a $23.7 billion industry, according to the Nutrition Business Journal.
What Are Dietary Supplements and How Are They Regulated?
98-year-old Bob Stewart, a retired podiatrist and senior Olympian, credits his use of supplements for his healthy aging. Writer Betsy McMillan, a mother of two now adult children, however, nearly suffered permanent liver damage due to a supplement that contained potentially fatal levels of niacin.
Unlike pharmaceuticals—which must be FDA-approved as safe and effective before they can be marketed—supplements are considered as foods by regulators and assumed to be safe until proven otherwise. Although pharmaceutical manufacturers face inspections to ensure that the right dose is in the right pill without dangerous contaminants, supplements do not undergo such intense government scrutiny.
Despite many reports of health problems, Read more »

Prince Charles is a big supporter of “natural” medicine, which in practice means unscientific and ineffective medicine. He has no particular expertise in this area, and there is absolutely no legitimate reason why he should have any influence over the practice of medicine in the UK. But he is the Prince of Wales, and he has chosen to use that celebrity to promote CAM.
Prince Charles has also recently been criticized for his credulous support for medical nonsense. The Telegraph recently reported that Simon Singh, co-author with Edzard Ernst of Trick or Treatment, and exposer of CAM pseudoscience, spoke about Prince Charles at the recent Hay Festival in India. Singh had some sharp criticism, including:
He only wants scientific evidence if it backs up his view of the natural treatment of health conditions…
We presented evidence that disputes the value of alternative medicine and despite this he hasn’t changed his mind…
Singh’s point is that Prince Charles is Read more »

Ever since I was a teenager, I’ve intermittently read Consumer Reports, relying on it for guidance in all manner of purchase decisions. CR has been known for rigorous testing of all manner of consumer products and the rating of various services, arriving at its rankings through a systematic testing method that, while not necessarily bulletproof, has been far more organized and consistent than most other ranking systems. True, I haven’t always agreed with CR’s rankings of products and services about which I know a lot, but at the very least CR has often made me think about how much of my assessments are based on objective measures and how much on subjective measures.
Until now.
I just saw something yesterday on the CR website that has made me wonder just how scientific CR’s testing methods are, as CR has apparently decided to promote alternative medicine modalities by “assessing” them in an utterly scientifically ignorant manner. Maybe I just haven’t been following CR regularly for a while, but if there’s an article that demonstrates exactly why consumer product testing organizations should not be testing medical treatments; they are ill-equipped to do so and lack the expertise and knowledge. The first red flag was the title, namely Hands-on, mind-body therapies beat supplements. The second red flag was the introduction to the article: Read more »

On Saturday, while thousands of Boston Bruins fans gathered at Government Center to celebrate the team’s recent Stanley Cup victory, a hundred or so true die-hards met a few blocks away at a Massachusetts General Hospital conference to talk about complementary and alternative medicine for psychiatric disorders. While I hated to miss the Bruins parade, I’m glad I attended the MGH conference.
I’ve always been a bit of a skeptic about so-called natural therapies for one simple reason: they don’t have to go through the same rigorous testing in clinical trials that medications do. At the same time, I realize that FDA-approved drugs don’t work for everyone. One in three adults with major depression, for example, can’t completely improve their mood and other symptoms even after trying multiple antidepressants.
Clearly, we need better options for treating mental health disorders. The MGH conference convinced me that some types of complementary and alternative medicine—or CAM, for short—might be worth trying. The presenters, all psychiatrists who treat patients at MGH, backed up their recommendations with scientific evidence. Several of them also contributed to the American Psychiatric Association’s recent report on CAM therapies.
We’ll be doing a story on CAM therapies for psychiatric disorders in an upcoming issue of the Harvard Mental Health Letter. For now, here are some things I learned on Saturday: Read more »
