Vasodilation Ginkgo promotes vasodilation and improves blood flow through arteries, veins and capillaries. Increases in microcirculatory blood flow occur rapidly and have been confirmed under randomised crossover test conditions 1 hour after administration (Jung et al 1990).
Several mechanisms of action are responsible. Currently, these are considered to be: inhibition of NO release, activation of Ca2+-activated K+ (Kq,) channels, and increased prostacyclin release (Nishida & Satoh 2003).
Reduces oedema Various flavonoids including anthocyanosides and G. biloba extracts have been shown to be effective against experimentally induced capillary hyperfiltration (Cohen-Boulakia etal 2000).
