COGNITIVE ENHANCEMENT
Research Findings

Alzheimer's Disease (AD)

Amyloid beta-peptide has been found to have a role in the free-radical
oxidative-stress model of neurotoxicity in Alzheimer's disease. Hydrogen
peroxide level was elevated with AD-associated transgenic cells expressing
the amyloid beta-peptide. Treatment of these cells with Ginkgo biloba extract
significantly attenuated the basal as well as the hydrogen peroxide-realted
reactive oxygen species levels.

Alzheimer's disease models can be attenuated by Ginkgo biloba extract

Cognition/thinking-enhancing (nootropic)

Wesnes et al evaluated the effect of a Ginkgo/ginseng combination on
cognitive function of 64 healthy subjects (aged 40-65) in a 90-day, double
blind, placebo-controlled, paralel-group study using. They assessed the
subjects' performance on cycle ergometry and various questionnaires before
and after dosing. They found that a 80-mg dose produced a significant
benefit on the ergometry assessment of heart rate at maximum load.

ginseng combination in health volunteers with neurasthenic complaints.

Memory Effects

Petkov et al studied the effects of the ginseng, ginkgo biloba extracts on
young and old rats using some conditioned-reflex methods. The extracts
were administered orally for 7 days before the study. They found that the two
extracts and their combination improved the retention of learned behavior.
Their combo is particularly promising in geriatric practice.

Blood Pressure Lowering Effect

A preparation containing 60 mg ginkgo biloba and 100 mg ginseng was
administrated to 10 voluntary subjects with a mean age of 26. The
researchers found their systolic blood pressure decreased significantly at a
double dose and single dose. While, diastolic blood pressure decreased
only at the double dose.

Ginkgo Biloba  is best known for its ability to enhance circulation systemically. Its action is directly related to the
vaso-relaxing activity. Thus, Ginkgo Biloba can lower blood pressure and inhibit platelet aggregation. Scientific studies
have shown its promise on cognition-enhancement (booster). If used during the early stages of Alzheimer's disease,
the mental deterioration may slow down. The user can expect results only after taking the product for 3-6 months on a
daily basis. Contra indications include not taking the product before surgery, so you should check with your doctor
before undergoing any procedure.
