Based on the prevalence and economic costs and physical- psychological side effects caused by tinnitus and the importance of finding a suitable solution for its prevention and treatment, the need for further studies becomes more obvious in this context. This review article aimed to review studies on the effectiveness of Ginkgo biloba as a medicinal plant on patients with tinnitus. EVIDENCE ACQUISITIONS Google Scholar, Directory of Open Access Journals (DOAJ), PubMed, LISTA (EBSCO) and Web of Science have been searched. RESULTS There are many studies on the therapeutic effect of Ginkgo biloba on patients with tinnitus. Most findings are in contrast with each other so that some of studies reported that Ginkgo biloba is effective in the treatment of tinnitus and other studies referred to it as ineffective herbal medicine. Generally, according to the previous studies and the present study, it can mention that the Ginkgo biloba may somewhat improve tinnitus.
