A paper in the JAMA, December 23th, 2009 gives the results of a study testing the effects of a Ginkgo biloba extract, comparatively to a placebo, on memory and the cognitive performances of people between 72 to 96 years. The extract of Ginkgo biloba was used at the dose of 120 mg twice daily. This study which lasted 6 years did not find beneficial or adverse effects of Ginkgo biloba on memory nor on cognitive decline in normal or already impaired people.
This study confirms other negative results. Ginkgo biloba, as it seems to have rather little adverse effects and is not very expensive, can constitute a useful placebo.
