(Also Yin Guo)
The healing tree Ginkgo biloba is the only surviving representative of its class ( Ginkgoopsida ) related to conifers. It is an ancient and long-lived bivalve tree with edible fruits (ginkgo nuts) and curative effects. Jinan is recommended in combination with other adaptogens to improve mental functions ( nootropic effects ). According to Ihl2012gbe , the ginkgo extract EGb761 is at least as effective as nootropics of memantine, galantamine and donepezil. According to Janssen2010gba, gingival adaptogen is suitable for Alzheimer's disease . But there are also many reviews that completely deny the nootropic effects of ginkgo, for all I 'm going to say Laws2012igb .
