The Hormone Myth

“Mary is really bitchy today; she must be on the rag.” Comments like this are all too common, and are misguided. In her new book, Robyn Stein DeLuca dispels the myths about how hormones affect women’s moods and mental health, myths that have contributed to unequal treatment of women. Junk science supported the myths; good

Chiropractic Gynecologist Offers Dangerous Treatments and Misinformation

Over a year ago I wrote about escharotic treatments for cervical dysplasia. It is offered not by MD gynecologists but by chiropractors and naturopaths, along with inconsistent and unproven diet recommendations and supplements. A corrosive agent similar to “black salve” is applied repeatedly to the cervix; it works by destroying tissue. There are no controlled studies

Quackery: The 20 Million Dollar Duck

The publisher recently sent me a review copy of Quackery: The 20 Million Dollar Duck, by Tony Robertson. My first thought was “Do we really need another book on this subject? Don’t I know all this stuff already?” I was very pleasantly surprised. Robertson has ferreted out an impressive array of facts and details that I

Prenatal Multivitamins and Iron: Not Evidence-Based

When I was pregnant, I obediently took the iron pills and prenatal vitamins prescribed by my obstetrician. And I prescribed them for every pregnant patient I took care of as a family physician. I never questioned the practice. It seemed intuitively obvious that it was a good thing; we know pregnancy makes extra nutritional demands

Vaginal Birth After C-Section: How Safe Is It?

Doctors used to insist “once a C-section, always a C-section.” Today it is standard practice to allow vaginal births after C-section (VBAC) for appropriately selected patients. The American Congress of Obstetricians and Gynecologists (ACOG) has issued a Practice Bulletin to guide obstetricians in determining which patients are appropriate candidates for VBAC. We frequently hear criticisms of practice

Escharotic Treatment for Cervical Dysplasia: A New Incarnation of Black Salve?

Bloodroot (Sanguinaria canadensis) and black salve (which contains bloodroot) are promoted and sold as a cure for many things, including cervical dysplasia. While it does kill cancer cells, it does so just like a flamethrower – indiscriminately, killing lots of normal cells along the way. Flowers of the bloodroot plant, Sanguinaria canadensis. You’re welcome, I could

The Human Mold: Another Example of Self-Deception

  José Jarimba believes that our bodies are physically molded into an asymmetric form by our mothers’ sleeping positions during pregnancy, that this has lifelong adverse impacts on health, and that shoe inserts can eliminate pain and other health problems by realigning the body. This is a silly untested hypothesis by a single individual. As

Antibiotics vs. the Microbiome

In 1850, one in four American babies died before their first birthday, and people of all ages died of bacterial infections that could have been successfully treated today with antibiotics. Unfortunately, treatments that have effects usually have side effects, and we are seeing problems due to the overuse of antibiotics. They are given to people

Nature vs. Technology

For those who dismiss advocates of the “natural” as ignorant of science and deluded by the logical fallacy that natural = best, Nathanael Johnson’s new book is an eye-opener: All Natural: A Skeptic’s Quest to Discover if the Natural Approach to Diet, Childbirth, Healing, and the Environment Really Keeps Us Healthier and Happier. If nothing else,
