Many studies have been done on the natural herb, Ginko Biloba, it was even used by the ancient Chinese. It enhances the cognitive abilities by opening the blood vessels in the brain, thereby enabling an individual to receive more oxygen and think more clearly... I myself have taken it from time to time and it has seemed to help me remember things better when studying or preparing for a test. You can do online searches and come up with numerous information on this. I would encourage some of you to at least give it a try for a short period of time and remember that it is totally natural, it is not a drug...
Wow, that is interesting. In Physiology class, we have been studying some of the herbs that hel with certain conditions and gingko biloba seems to be pretty popular. It increases the time it takes to form a clot, which is good for people with high blood pressure and high cholesterol.
