Ginkgo Biloba Extract

Active Substances: Ginkgo flavoglycosides
(kaempferol, quercetin, isorhamnetin, proantho-cyanidins), terpenes
Standard: 24% ginkgo flavoglycosides, 6% Terpene Lactones

Description:
The main active compounds in Ginkgo leaves are the flavo-glycosides: 
kaempferol, quercetin, isorhamnetin, and proantho-cyanidins. 
These compounds have  anti-oxidant and free radical properties. Also 
important are the terpenes: ginkgolides and bilobalides. One way these 
agents decrease inflammation   is by inhibiting the Platelet Activating 
Factor (PAF) and reducing the stickiness of platelets, which can result in 
decreased circulatory flow.  PAF has been implicated in a wide variety of 
diseases including asthma, heart arrhythmias, myocardial infarction, and 
atherosclerosis.


Numerous studies have detailed the efficacy of Ginkgo biloba extract (GBE) for a
wide variety of conditions. GBE has been reported to increase circulation to the
brain and thus help with cases of dementia, Alzheimer's disease, memory loss,
 concentration problems, vertigo, tinnitus, and dizziness. Peripheral vascular 
diseases such as Raynaud's syndrome, intermittent claudication, numbness and 
tingling have been helped by GBE. Studies have also reported that GBE was 
helpful in cases of head injuries, macular degeneration, asthma, and impotence.
