Ginkgo biloba not useful in preventing dementia

Still think they know what an effective supplement is?

"Although often billed as a memory and cognition enhancing product, the medicinal herb Ginkgo biloba does not stave off cognitive decline or help prevent dementia and Alzheimer's disease, according to a report in the Journal of the American Medical Association this week."

Oh, and by the way, it may not be safe, either.

"Compared with placebo, Ginkgo use was associated with a slightly increased risk of dementia and Alzheimer's disease."

Perhaps the true test of dementia is whether you take ginkgo.

If you do, maybe you got it.
