What does Ginkgo Biloba do?
Ginkgo biloba extract helps to maintain normal blood circulation and cardiovascular function, particularly normal blood vessel tone and elasticity, and normal blood platelet aggregation. Maintenance of normal blood supply to the brain helps to preserve mental function in the elderly. Ginkgo biloba extract also has powerful antioxidant activity, protecting tissues (particularly brain tissue) from free radical induced damage.

Are there adverse effects from taking Ginkgo biloba?
Ginkgo biloba is generally well tolerated, with no significant adverse effects reported during use; gastrointestinal disturbance or headaches may occasionally occur in susceptible individuals.

Supplements containing Ginkgo biloba extract should be taken with caution by patients prescribed anti-coagulant drugs (e.g. aspirin, warfarin). The toxicity of Ginkgo biloba extract is very low.

Ginkgo Biloba and Alzheimer's disease
Clinical trials have demonstrated the effectiveness of standardised extracts of Ginkgo biloba for the stabilisation or improvement of mild to moderate Alzheimer's disease (using dosages of 120-240mg/day for 3-6months).

This improvement in symptoms is comparable to or greater than that obtained with conventional synthetic drugs such as tacrine, but without the harmful side effects associated with the latter. Chemical substances with powerful antioxidant activity are thought to contribute to the effectiveness of Ginkgo biloba extract in Alzheimer's disease patients.

Ginkgo Biloba and antioxidant activity
Antioxidants counter the damaging effects of toxic molecules produced within the body called free radicals, which have been implicated in a variety of diseases including Alzheimer's disease.

A study by British scientists to compare antioxidant activity in 18 Ginkgo biloba brands has recently been published in the Journal of Alternative and Complementary Medicine. Antioxidant activity was measured using a standard laboratory test, and expressed on a per mg ginkgo basis to enable comparison between tablets of different sizes.

There was a 50-fold difference in activity between the samples, with Pharma Nord Bio-Biloba having the highest level of antioxidant activity. This variability can be partly explained by the type of Ginkgo biloba used- some products are based on dried leaf powder, whilst others use Ginkgo biloba in a more concentrated (standardised extract) form.

However even when comparing the latter products, there is still a considerable variation in antioxidant activity, which presumably must result from differences in manufacturing processes used by different suppliers.
 

The composition of commercially available extracts of Ginkgo biloba may vary; extracts should be standardized to contain 24% flavone glycosides and 6% terpene lactones. Unprocessed leaves should not be used (e.g. in teas), as they contain chemicals (removed during processing) which can trigger allergic reactions.
