I’m only a monthly contributor here, but between being a Science Based Medicine (SBM) reader and having my own blogs, I often grow weary of the blind criticism that researchers and drug companies couldn’t care less about traditional folk medicines as drug products. My laboratory spends every single day working on natural product extracts in the search for compounds that may have selective effectiveness against cancer. So this is a bit of a sore spot for me.
Two [recent] papers from Cancer Prevention Research on the potential anticancer effects of a diabetes drug (see Nathan Seppa’s story here) remind me to tell the story of a Middle Ages European herbal medicine used to treat polyuria that gave rise to one of the most widely prescribed drugs in the world, metformin (Glucophage in the U.S.). Metformin, known chemically as a biguanide, dimethylguanide to be precise, traces its roots to the plant Galega officinalis. Known as goat’s rue, French lilac, or professor weed, this plant was shown to be a rich source of guanidine and a less toxic compound later called galegin or galegine (isoamyline guanidine).

The news wasn’t good this week for women concerned about breast cancer.
First came the story that some women were diagnosed with breast cancer, very early stage, had treatment –- including disfiguring surgery -– and then found out they never had cancer in the first place. The pathologist goofed, maybe even a second pathologist also misread the biopsies.
How does this happen? Not surprisingly it comes back to the clinical experience of the doctor. Properly diagnosing breast cancer, whether through radiology scans or pathology biopsies is not always easy. And in many communities the general radiologists and pathologists just don’t have enough specialized experience. This leads to mistakes, especially when the suggestions of possible cancer are subtle and minute. Read more »

They have a tough job, those government doctors, scientists, and bureaucrats who are charged with assessing the safety and effectiveness of proposed new medical products. As you know, they rely largely on studies presented by the applicants.
The Food and Drug Administration (FDA) has the power to not approve a new drug or product or even pull it off the market. Right now it is considering limiting or pulling GlaxoSmithKline’s (GSK) diabetes drug, Avandia, because of newly discovered data that it may have caused heart attack in some patients –- data mysteriously not shown in GSK’s own studies. If the drug is pulled it will cost GSK billions of dollars in lost revenue but, from the FDA’s point-of-view, it will be protecting the public. And, after all, there are safer diabetes drugs on the market as alternatives. Read more »
