I've taken similar herbals expecting the same or better results and not realized any.
I take a 90mg gelcap and the effect lasts for about 3 hours every time.
It's pretty predictable to be placebo.
Again, from what I've learned it's a circulation issue. Ginkgo increases circulation to the brain and other extremities and that helps your cognitive function. I don't have any issues with my extremities so I can't comment about that.
My wife tried some (she is typically very focused already) and she said it had no effect. So I'd agree that it doesn't work for everyone but does for some.
