A consumer interest group wants the federal government to pull products that contain the herbal extract Ginkgo biloba from the marketplace, pointing to studies that show it could cause cancer.
The Center for Science in the Public Interest, a nonprofit health advocacy group, is warning that extracts of the plant can cause cancer and are not safe. The group wants the government to make sure that Ginkgo is removed from food and drinks.
Ginkgo, one of the most popular herbal supplements, is often taken to improve memory function and blood circulation, among other uses, but has never been definitively proven to be beneficial. In March, however, a report on studies from the National Toxicology Program found that the extract caused cancer in rats and mice.
