Problems Persist With Ginseng Supplements

Alternative Medicine, Men's Health, Woman's Health
Long-time readers know of my fondness for ConsumerLab.com. Their independent testing of natural medications (herbs, vitamins, and supplements) guides my teaching and my prescribing. Now, a review by ConsumerLab.com finds 45% of ginseng products don’t provide the full amount of the ingredient indicated on the label, or worse, are contaminated. ConsumerLab.com is now reporting that five out of eleven of the most popular ginseng supplements in the U.S. were selected for testing and contained less ginseng than expected from their labels or were contaminated with lead and/or pesticides. Problems with the quality of ginseng supplements have been reported by ConsumerLab.com since 2000. Ginseng is a popular herb with U.S. sales last year of $83 million according to Nutrition Business Journal. "Consumers need to be wary of the quality of ginseng…

Stricter government oversight of dietary supplements may be moving closer – thank goodness

Alternative Medicine, Nutritional Health
Whenever I give talks on natural medications (herbs, vitamins, and supplements), whether to healthcare professionals or laypersons, people seem shocked to learn that these substances are virtually unregulated in the United States. I've written about the many problems this causes healthcare professionals and consumers in my book, Alternative Medicine: The options, the claims, the evidence, how to choose wisely. So, I was very happy to read an AP article reporting "Stricter government oversight of dietary supplements is moving closer, thanks to an agreement among senators to include guidelines in" the Dietary Supplement Safety Act. The report says that in a letter sent to Sen. Tom Harkin (D-IA), chairman of the Senate Health, Education, Labor and Pensions Committee, Sens. John McCain (R-AZ) and Byron Dorgan (D-ND) outlined "four key areas of…

Alternative Medicine, Heart Health
The folks at Natural Standard recently sent out a notice of a significant review in the cardiology literature on the potential interactions between herbs and heart medications. A news release on the study can be found here. This new analysis suggests that herbal supplements, such as Ginkgo biloba and garlic, may cause dangerous interactions when combined with heart medications. Some examples of herbs and their adverse effect on heart disease management include: St. John’s wort, which is typically used to treat depression, anxiety and sleep disorders among other problems, reduces the effectiveness of medications contributing to recurrences of arrhythmia, high blood pressure or increase in blood cholesterol levels and risk for future heart problems.

Newly released test show most Milk Thistle supplements are substandard

Alternative Medicine, Nutritional Health
White Plains, New York — December 2, 2009 — A recent review by ConsumerLab.com of ten milk thistle supplements showed that only one met ConsumerLab.com’s quality standards.  Two products failed to properly list the part of the milk thistle plant used -- a FDA requirement.  Among the remaining supplements, only one contained the expected amount of silymarin compounds, which are believed to be the active constituents of milk thistle. Studies suggest silymarin may be helpful in type 2 diabetes and, possibly, certain liver conditions.  While most products claimed that their milk thistle extracts were standardized to 80% silymarin, ConsumerLab.com found actual amounts to range from 47% to 67%.  Sales of milk thistle in the U.S. have climbed for several years, reaching $95 million in 2008 according to the latest figures…

Some herbal supplements associated with dangerous blood lead levels in women

Alternative Medicine
Reuters Health carried a very interesting report indicating that some herbal supplements may boost the levels of lead in the blood of women. A study, published in November showed that among 12,807 men and women age 20 and older, by Dr. Catherine Buettner, at Beth Israel Deaconess Medical Center in Boston, Massachusetts, and colleagues found blood lead levels about 10 percent higher in women, but not men, who used specific herbal supplements. When they examined herbal supplement use among women of reproductive age (age 16 to 45 years old), "the relationship with lead levels was even stronger, with lead levels 20 percent higher overall, and up to 40 percent higher among users of select herbal supplements compared to non-users," they report in the Journal of General Internal Medicine. Lead accumulates…
