    Ginkgo biloba leave extract is among the most widely sold herbal
    dietary supplements in the United States. Its purported biological
    effects include: scavenging free radical; lowering oxidative stress;
    reducing neural damages, reducing platelets aggregation; anti-
    inflammation; anti-tumor activities; and anti-aging. Clinically, it
    has been prescribed to treat CNS disorders such as Alzheimer's disease
    and cognitive deficits. It exerts allergy and changes in bleeding
    time. While its mutagenicity or carcinogenic activity has not been
    reported, its components, quercetin, kaempferol and rutin have been
    shown to be genotoxic. There are no standards or guidelines regulating
    the constituent components of Ginkgo biloba leave extract nor are
    exposure limits imposed. Safety evaluation of Ginkgo biloba leave
    extract is being conducted by the U.S. National Toxicology Program.
