Supplementation of ginkgo biloba daily for a period of 8 months was associated with improvements in cerebral blood flow in most tested regions (left frontal, frontoparietal, and parietal and right frontal and parietal lobes).
General systemic blood viscosity was also noted to be reduced with supplementation, and global cognitive scores improved.
