Ginkgo Biloba
Ginkgo Biloba is perhaps one of the most well-known herbal supplements available these days, and doctors have approved it for use in the treatments of a variety of ailments from tinnitus to bronchitis, and even forgetfulness. It has also been recognized by millennia in Traditional Chinese Medicine. It works primarily by increasing blood circulation to all the tissues of the body, including in the microcirculatory system (the capillaries). That's why ginkgo biloba has a reputation for increasing memory and concentration, because of increased blood flow and increased oxygenation of the blood to the brain. For the same reason, ginkgo biloba can be a powerful male sexual stimulant.
Last but not least, it's a potent antioxidant, and you can never get enough of those. On the negative side it can inhibit blood clots, and so we advise speaking with a doctor before including ginkgo biloba in your nutritional regimen.
