Ginkgo biloba extracts for tinnitus: More hype than hope?

Abstract:

:The investigation into the effects of Ginkgo biloba extracts on tinnitus has suffered from a dearth of effective animal models as well as systematic clinical trials employing double-blind and placebo-controlled designs. Some clinical trials have yielded positive results, however, these studies are few and have been limited either by design flaws, the small size of the significant effects, or else the results have not been published in peer-reviewed journals and therefore the quality of the research is not assured. By contrast, the two most systematic clinical trials, both double-blind and placebo controlled, and published in respected peer-reviewed journals, have yielded negative results and suggest that Ginkgo biloba extracts are of little more use in the treatment of tinnitus than a placebo. Treatments for tinnitus that do not have therapeutic efficacy not only waste money but can potentially prevent patients from seeking therapy that is efficacious. Furthermore, the unsupervised use of Ginkgo biloba extracts with other medications could lead to adverse side effects which are unnecessary and not justified in terms of therapeutic benefit.
