There is currently no medication that is universally effective for tinnitus. Which treatment may be appropriate depends on factors such as the underlying cause, how long the symptoms have been present, and any accompanying medical conditions. Newly occurring or distressing tinnitus should therefore be evaluated by a doctor. One of the best-known ginkgo medicines is Ginkobil, which contains a standardized Ginkgo biloba extract. Experiences with Ginkobil for tinnitus vary: while some users report a subjective reduction in the sounds they hear, others notice no change.
