Det foreligger ingen overbevisende dokumentasjon for effekt av Ginkgo biloba på kognitiv svikt, demens, akutt iskemisk slag, claudicatio intermittens, tinnitus eller aldersrelatert makulær degenerasjon
I placebokontrollerte, kliniske studier er bivirkninger ved Ginkgo biloba sammenliknbare med placebo
Resultater fra GuidAge-studien vil trolig gi nyttig informasjon om eventuell effekt av Ginkgo biloba på aldersrelatert makulær degenerasjon og eventuelt interaksjonspotensial med warfarin (antikoagulantia)
