As the name suggest Ginko BIloba has leaves that resemble the two lobes of the human brain. The leaf is a cross section of the human brain taken from the centre left to right. It even includes a reference to the brain stem in the leaf's own stem. The ancient herbalist called this divine nomination.

As a result Ginko has been traditionally used to maintain cognitive function and improve memory. It contains Ginkosides that enhance cerebral circulation.
