Try liquid choline chloride instead of focusing on herbal stuff. Gingko biloba supposedly helps circulation to the brain, but if it has an effect, it can be pretty subtle, from my experience. I don't even notice it. But I do notice liquid choline chloride, tremendously. It get converted into acetylcholine in the body, a neurotransmitter. Your body's supply can get low, and that can lead to feeling like you're thinking slower. Conversely, resupplying it can feel like a great mental pick me up, much like coffee but without any negative side effects or the chance to make you spacy and diffuse in your attention.
