The German Commission E, one of Europe’s most respected herbal standard authorities, has defined the active components of ginkgo biloba extract as 22 to 27% flavonoid glycosides, and 5 to 7% terpene lactones. BioGinkgo is standardized to 27% ginkgo flavone glycosides and 7% terpene lactones, one of the highest levels available in a ginkgo product. This is made possible by a novel extraction process.
