About Ginkgo

EGb 761 is a specific, standardized extract of Ginkgo biloba leaves, developed and trademarked by Dr. Willmar Schwabe Pharmaceuticals. It is one of the most extensively researched botanical extracts worldwide, with a defined chemical profile and consistent pharmacological activity. The extract is standardized to contain 22-27% flavonol glycosides and 5-7% terpene lactones (ginkgolides A, B, C, and bilobalide), with ginkgolic acids limited to less than 5 ppm to minimize allergenic potential. This precise standardization ensures batch-to-batch consistency and reproducible clinical effects, primarily targeting cerebral and peripheral circulatory function, neuroprotection, and antioxidant activity.
