Native to China, the ginkgo biloba tree (of the Ginkgoaceae family) is distinguished by its wide, leathery, fan-shaped leaves and sturdy trunk. The name is derived from the Japanese word ginkyo, meaning "silver apricot." Ginkgos are known for their remarkable longevity; some trees growing in China are over 2500 years old. In the United States, they grow in hardiness zones 3 to 9. Unfortunately, these trees are also notorious for the horrid smell--similar to vomit or rotten eggs--produced by seeds that fall and rot. From a distance, though, ginkgo trees are beautiful.
What is Ginkgo Biloba Extract ?
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. ( 1 of 3 adults in the United States are now taking dietary supplements ).
Gbe is a well defined product, and it or its active ingredients, the ginkgolides, especially ginkgolide B, and bilobalide, have clearly demonstrated biological activity. It can be consumed in rather large doses for an extended period of time. Under the Dietary Supplement Health and Education Act of 1994, Gbe can be sold legally if it is not labeled or accompanied by any therapeutic or health claims. Herbal remedies can be labeled with descriptions of their role in affecting physiological structure or function, but must be labeled with a disclaimer that the product has not been evaluated by the FDA for cure, prevention, or treatment of a disease.
