Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Ginkgo biloba, particularly its flavone glycosides, has been traditionally used in various systems of medicine for conditions related to cognitive function and circulation, including tinnitus. The rationale stems from the belief that Ginkgo improves blood flow, especially to the brain and inner ear, potentially alleviating symptoms like ringing in the ears. This traditional use is most pronounced in European phytotherapy and Chinese herbal medicine, where Ginkgo leaf extracts have been recommended for conditions involving impaired circulation and auditory disturbances.

Scientific studies on Ginkgo biloba for tinnitus have produced mixed results. Some early small-scale trials and anecdotal reports suggested possible benefit, but more recent and larger randomized controlled trials have generally not demonstrated a significant effect of Ginkgo on tinnitus compared to placebo. Systematic reviews and meta-analyses, such as those by Cochrane, conclude that Ginkgo biloba is probably not effective for treating tinnitus in the general population. However, Ginkgo remains widely marketed and used for this purpose based on longstanding tradition and its plausible mechanism of action involving microcirculation.

In summary, while its use for tinnitus is rooted in tradition and supported by historical usage, robust scientific validation is lacking, resulting in a low but not zero evidence rating.
