Ginkgo Biloba
The Ginkgo tree is one of the oldest living species on the planet. It has flourished unchanged for over 150 million years has been used in Chinese medicine for over 5,000 years. The leaves and fruit of the Ginkgo tree contain a variety of phytochemicals that have a wide range of clinically proven benefits. Ginkgo significantly increases blood flow to the brain thereby improving cognitive function, memory, alertness and concentration. It also improves peripheral arterial insufficiency (restriction of blood flow to the legs and other extremities, including the genitals).
