 Since the 1960s, extensive research has been done on ginkgo which established its importance in improving poor cerebral circulation, aiding memory and concentration, and helping in cases of dementia.Research has shown that ginkgolide can be as effective as standard pharmaceuticals in treating severely irregular heartbeats. It also seems to have the ability to reduce inflammation, and may prove useful in treating such varied conditions as autoimmune disorders, multiple sclerosis, and organ transplants.
 Research into its platelet activating factor (PAF), a substance released by a range of blood cells, has led to the understanding of a new branch of human physiology. PAF causes blood to become stickier and more likely to produce blood clots, but Ginkgo seems to inhibit this from happening. In addition, it also makes various inflammatory and allergenic changes.
 Plantations in the US process the dried leaves, creating a concentrated extract standardized to a potency of 24% flavone glycosides (primarily quercetin, kaempferol, and isorhamnetin) and 6% terpene lactones (about equal parts of bilobalide and ginkgolides A, B, and C). This extract, called GBE (ginkgo biloba extract) is the form now used medicinally and under study for active ingredients and effects.

 How much Ginkgo biloba.Ginkgo Biloba Extract is beneficial?
 Various studies have been conducted using Ginkgo Biloba Extract dosages from 30 mg to 600 mg per day. However, in many studies, there is no reference to the levels of the primary actives such as ginkogosides and terpenes. Obviously, a Standardized Formula would be more effective at lower dosages. For best results use only Ginkgo biloba that has been standardized to contain a content of 24% ginkgosides and 6% terpenes. Non-standardized products may not be effective. As a dietary supplement to enhance brain function and prevent circulatory disorders, begin with a minimum of 60 mg. each day, increasing your daily consumption to 120 mg. For chronic long term conditions, 360 mg per day (6-60mg capsules per day) is the dosage recommended by most herbalists. It is recommended that you take the least amount at which you can see measurable results. Long term studies indicate that there are no toxicity concerns, even at levels of 600 mg. or more. Greater benefits may be obtained when the product is enhanced with other natu-ral herbs such as Aloe Vera Extract.

 Conclusion:
 Ginkgo biloba has been around since the age of dinosaurs. It has survived mass extinctions, ice ages, atomic explosions and environmental pollutants without damage. Visionary healers have tapped the resources of this amazing herb since the beginning of recorded history. Now with the aid of advanced diagnostic equipment and devices, we are able to unlock some of the mysteries of its phytochemical composition and release its secrets to the masses. It may well be the world's oldest "smart drug". To ensure that you obtain the greatest possible benefit, check the label and select only standardized formulas from reputable companies willing to produce a certificate of analysis.

 Basis for Nomination to the CSWG:
 Ginkgo biloba extract (GBE) and two ingredients, bilobalide and ginkgolide B, are presented to the CSWG as part of a review of botanicals being used as dietary supplements in the United States. Herbal products represent the fastest growing segment of the vitamin, mineral supplements, and herbal products industry, an industry expected to top $6 billion in sales by 2001. GBE is an extremely popular herbal supplement; sales in 1996, the last year figures were available, exceeded $100 million.
 Indications are that one in three adults in the United States are now taking dietary supplements. Sweeping deregulation of botanicals now permits GBE to be sold as a dietary supplement to a willing public eager to "improve brain functioning" or "promote radical scavenging activity."

 GBE was selected for review for several reasons. First, GBE is a well defined product, and it or its active ingredients, the ginkgolides, especially ginkgolide B, and bilobalide, have clearly demonstrated biological activity. Second, GBE can be consumed in rather large doses for an extended period of time. Third, some ingredients in GBE are known mutagens; in one case, a suspected high dose carcinogen, quercetin, is intentionally concentrated from the ginkgo leaf to manufacture the final product.

 Adult Dosage of Ginkgo Biloba:
 Initial results often take 4 to 6 weeks, but should continue to accumulate beyond that period. You may not see any dramatic changes for six months.
 GBE: 120 mg daily in two or three divided doses of 50:1 extract standardized to 24% flavone glycosides (flavonoids). If more serious dementia or Alzheimer's disease is present, up to 240 mg daily in two or three divided doses may be necessary.
 Tincture (1:5): 2 to 4 mL three times a day
