There are a whole cluster of symptoms to do with both body and brain function that are linked to problems with impaired cerebral circulation. There is scientific evidence from 40 high quality clinical trials that gingko extracts are particularly effective. The recommendation is that Gingko Biloba extract could have a wholly beneficial effect on older people suffering from problems with circulation

Extracts from the leaves of gingko biloba have been used therapeutically for centuries, especially in Chinese medicine. The extracts contain a number of complex organic molecules, including a family of gingkolides. These are know to be platelet-activating factor antagonists (PAF-antagonists), a group of substances with therapeutic potential in a range of clinical conditions.

The main indications for gingko are peripheral vascular disease such as intermittent claudication and "cerebellar insufficiency". This latter is an imprecise term that describes a collection of symptoms, especially in elderly people:-

Difficulties of concentration and memory

Absentmindedness

 Confusion

Lack of energy

Tiredness

Decreased physical performance

Depressive mood

Anxiety

Dizziness

Tinnitus

Headache

All of these are associated with impaired cerebral circulation.

Clinical Trials . 40 clinical trials were found for gingko extract used in cerebral insufficiency. The results were homogeneous - virtually all produced positive results for gingko extract taken at about 120 mg a day for 4 - 6 weeks. Adverse effects are reported as rare.

As the number of elderly people grow, it seems to me that more information should be made available about the beneficial effects of Gingko Biloba, given that it doesn’t seem to have any adverse effects.
