Not sure where to post this, so mods: feel free to move this thread. Anyway, Ginko Biloba is a much advised herb here on the forum and I'm curious if there's any scientific studies or personal experiences that confirm it actually does the trick. I dug into the herb a few years ago to see if it really is an effective memory enhancer, but scientific studies showed that it actually does not cross the blood brain barrier. How exactly does it help in PE?
