Ginkgo is a circulatory tonic that has been shown to improve circulation by strengthening capillaries, making them more flexible, and allowing more red blood cells to squeeze through tight capillary beds. The effects of Ginkgo upon circulation to the brain and extremities has been particularly well studied.
In numerous studies into improving circulation to brain improvements in cognitive function have been noted including improvements in memory, alertness and overall cognitive performance. These benefits may be particularly felt in individuals suffering senile dementia or age-related cognitive decline.
