Research Findings

Ginseng ginkgo biloba benefit - Alzheimer's Disease
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. [1]

Ginseng ginkgo biloba benefit - Cognition
Wesnes et al evaluated the effect of a ginseng ginkgo 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.

neurasthenic complaints. [2]

Ginseng ginkgo biloba benefit - 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. Ginseng ginkgo biloba
combination is particularly promising in geriatric practice.

Ginseng ginkgo biloba benefit - 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.Hemorrheological and circulatory effects of gincosan (a combination of ginseng and ginkgo biloba). [4]

Ginseng ginkgo ADHD
Does ginseng ginkgo benefits people suffered from ADHD? A combination herbal product containing American
ginseng extract, Panax quinquefolium, (200 mg) and Ginkgo biloba extract (50 mg) (AD-FX; CV Technologies,
Edmonton, Alta.) was tested for its benefits on the symptoms of attention-deficit hyperactivity disorder (ADHD) in
36 children suffered from ADHD. After 4 weeks of treatment, the 44% of subjects exhibiting improvement for the
social problems attribute and 74% for the Conners' ADHD index and the DSM-IV hyperactive-impulsive attribute.
Five (14%) of 36 subjects reported adverse side effects. More studies are needed to clarify ginseng ginkgo
ADHD. [5]

COMMENT
As mentioned in the first section, ginseng and ginkgo biloba have similar biological effects or potential benefits
towards our body. Consequently, their combination potentiates their beneficial effects, however, their
combination theoretically may also potentiate their side effects. Do not take doses more the recommended
dosage. Users should consult with their doctors on the potential benefits and side effects of any supplements,
before taking them.

Ginseng Ginkgo Biloba Extracts
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.        

Ginkgo biloba has been combined with ginseng for a few conditions, and the researchers were excited for the
potential benefits of this combination. Why ginkgo biloba is combined with ginseng? It is because ginseng and
ginkgo biloba have a number of similarities. Firstly, both ginseng and ginkgo biloba has been used in traditional
medicine for thousands of years. Ginseng and ginkgo biloba are both believed to have benefits on memory,
actually, there are a few scientific evidence for their health benefits. Further, ginseng and gingko biloba are
both may benefit or support many conditions. Ginseng and ginkgo biloba both have been studied extensively
about their potential health benefits. Ginseng and ginkgo biloba both may benefits our central nervous system,  
circulatory system and reproductive system. Combining both ginseng and ginkgo biloba proved to be effective
in memory loss particularly those that are brought about by Alzheimer’s disease, and we shall discuss the
research findings on this aspect in the next section:
