Ginkgo biloba – No Effect
Dr Weil may disagree, but this appears to be the consensus...
Another one bites the dust.
The National Center for Complementary and Alternative Medicine (NCCAM) is generally a waste of taxpayer money, but they have sponsored several well-designed large trials of popular herbal supplements.

Ginkgo Biloba Doesn't Work For Anything. It's Just A Tree
Given that the science says this doesn't work, you might wonder how it is that hundreds of gingko biloba products are still on the market, all of them with claims about memory.

The Whispering Leaves of the Hiroshima Ginkgo Trees
How paradoxical, how sad, how stupid, it would be if, more than seven decades after Hiroshima opened the door to the possible suicide of humanity, we did not understand that warning from the past, that call to the future, what the gentle leaves of the ginkgo trees are still trying to tell us.
