Ginkgo biloba leaf extract (EGb) is a standardized botanical preparation derived from the dried leaves of Ginkgo biloba L., a relict tree species belonging to the family Ginkgoaceae. The extraction process typically involves harvesting mature leaves during the autumnal senescence phase, followed by a multi-step purification protocol to concentrate bioactive constituents. Modern industrial production employs solvent extraction (e.g., acetone-water mixtures) coupled with chromatographic enrichment to yield a refined extract standardized to contain 22-27% flavonoid glycosides (primarily quercetin, kaempferol, and isorhamnetin derivatives) and 5-7% terpene lactones (ginkgolides A, B, C and bilobalide).

Ginkgo biloba leaf extract been used in China for medicinal purposes for hundreds of years. Research performed during the past 15 years suggests that ginkgo may be of value in the treatment of age-related physical mental deterioration, dementia, peripheral vascular disease. Ginkgo may also reduce the severity of depression in individuals with cerebral dysfunction. Preliminary or uncontrolled studies suggest that ginkgo may benefit some patients suffering from tinnitus, vertigo, acute cochlear deafness, macular degeneration, cyclic edema and asthma.
