Ginkgo Biloba Extract

Ginkgo biloba extract comes from the fan-shaped leaves of the Ginkgo tree, one of the oldest living tree species on Earth (over 200 million years old!). In both traditional Chinese medicine (TCM) and modern herbalism, Ginkgo is best known as a brain tonic that supports memory, concentration, and circulation.

Most standardized extracts are concentrated to 24% flavone glycosides and 6% terpene lactones, which are the compounds responsible for its therapeutic benefits.
