Ginkgo biloba Extracts Like EGb 761® for Treatment of Non Common Indications – A Selection of Clinical Studies

Abstract

AbstractExtracts of Ginkgo biloba L. are one of the most commonly applied herbal medicines. The active constituents are flavonol glycosides and terpene trilactones in particular. The special extract EGb 761® is mentioned in the German S3 clinical guideline “Demenzen” as treatment option (“kann” recommendation). Some small- and large-scale clinical studies for Ginkgo biloba leaf extracts are summarized in this publication for the indications: Tardive dyskinesia, vitiligo, anxiety/anxiety disorder, visual impairment, mountain sickness, sudden hearing loss, attention deficient hyperactivity disorder (ADHD) in children and fatigue. The studies are of different quality and show variable results. More research is warranted to draw conclusions about the effectiveness of Ginkgo biloba extracts for those indications.
