Glucosamine and Chondroitin: Do They Really Work?

Glucosamine and chondroitin are widely used for osteoarthritis pain. My daughter even gives them to her elderly horse. Their popularity is puzzling, since the evidence from scientific studies indicates that they don’t work. Wikipedia has a useful survey of the history, studies, criticisms, and systematic reviews (https://en.wikipedia.org/wiki/Clinical_trials_on_glucosamine_and_chondroitin). It includes a long list of references. I

Genius Java: Memory Boosting Coffee

My local newspaper is an unending source of amusement in the form of ads for questionable health products—ads that demonstrate clever marketing tactics aimed at scientifically illiterate and gullible readers. Perhaps it is a waste of time to critique them, but I like to think that consumers can be educated about the deceptive methods these

The Truth About Cancer

Ty Bollinger’s documentary series “The Truth About Cancer” demonizes conventional oncology and promotes alternative cancer treatments. I recently wrote an article for Science-Based Medicine pointing out how very untruthful it is. I showed that it used unreliable sources and was full of lies, distortions, omissions, false claims, myths, fallacies, and frankly dangerous misinformation. The “Truth

Uninformed Consumers Are Treating Their Flu Symptoms with Muscovy Duck Offal (Minus the Duck)

What if you bought a can labeled “beef stew,” and when you got ready to enjoy a hearty dinner you found there was nothing in the can but water? What if you discovered fine print on the label that said “Contains no beef stew”? You would be upset. You might think that anyone would be

Newborn Babies Don’t Have Sex, So Why Do We Vaccinate Them for a Sexually Transmitted Disease?

Vaccination is arguably the greatest accomplishment of modern medicine; vaccines have saved millions from death and disability, and smallpox has been eradicated forever. But vaccines are not without their critics. Since Jenner first experimented with cowpox, there have been people who have rejected vaccinations for various reasons, usually appallingly wrong-headed ones. A strong anti-vaccine movement

Screening Tests and Primum non nocere

Primum non nocere is a Latin phrase meaning “first do no harm.” It is commonly attributed to Hippocrates, but if he ever said any such thing, he certainly didn’t say it in Latin. He lived in ancient Greece from 430 BC to 370 BC and presumably spoke Greek. The phrase, in English and in Latin,

Zombie Criticisms of Conventional Medicine

Alternative medicine, by definition, is medicine that is not supported by good enough evidence to have earned it a place in mainstream medicine. Some people insist that modern medicine is not evidence-based either! Not long ago I got an email from a man who said that and tried to prove it with a series of

“Biomagnetism Therapy”: Pseudoscientific Twaddle

In a television interview, a practitioner of biomagnetic therapy claimed she had cured her own breast lump and the metastatic cancer of another person. I wonder how many viewers believed her. On the “official website” of biomagnetism therapy, http://biomagnetism.net/, they claim it is “the answer to ALL your health problems… an all-natural, non-invasive therapy proven

Traditional Chinese Medicine (TCM) Didn’t Win a Nobel Prize, Scientific Medicine Did

Tu Youyou, a Chinese researcher, was awarded half of the 2015 Nobel Prize in Medicine for her discovery of , a malaria drug. This has been touted as a victory for traditional Chinese medicine (TCM) and herbalism. It is anything but. Treatment of malaria had become problematic; there were a number of effective medications, but
