Their degree of tinnitus and overall hearing was assessed at the beginning of the study and then every four weeks. Results: After four weeks of oral supplements, people taking ginkgo supplements had a significant decline in tinnitus volume (an average of almost 6 decibels), whereas those taking placebo had no consistent improvement.

In addition, hearing improved at some frequencies among people taking ginkgo, but not among those taking placebos. |
