Effectiveness of Ginkgo biloba in treating tinnitus
This study does not support the use of Ginko for treating ringing in the ears (tinnitus). This study does include a large number of patients, which will always improve the quality of a study. I do read these results with regret, but a few things need to be kept in mind. First, it is only one study, and one study does not establish or refute effectiveness. Next, we have to accept that herbs may not always be effective for the conditions that anecdotal cases suggest.
