Ginkgo biloba may have modest positive effects when used to treat tinnitus, reports the American Academy of Family Physicians. These findings reflect a body of inconclusive evidence. As of 2015, there is no FDA-approved treatment for tinnitus, says Harvard Medical School.
Ginkgo is used in Europe to treat tinnitus of vascular origin. Ginkgo appears to improve circulation, which might support the healthy functioning of eyes, ears, brain and legs, according to MedlinePlus.
The largest and best-executed trial conducted to assess the efficacy of ginkgo at treating tinnitus found no associated benefits, according to New York University Langone Medical Center. Smaller studies have produced conflicting results, with some finding no benefit and others finding the opposite.
Though exposure to loud noise is widely perceived to be the cause of tinnitus, ear obstructions, ear infections, head injuries, blood vessel disorders and abnormal bone growth in the ear are other potential causes, according to NYU Langone Medical Center. Treating the underlying cause may alleviate tinnitus.
As of 2015, weak evidence from a variety of studies suggests other potentially helpful therapies, such as CoQ10 supplementation, repetitive transcranial magnetic therapy, massage therapy, biofeedback and hypnosis, notes NUY Lagnone Medical Center.
Zinc deficiency is common in people with tinnitus, according to one double-blind, placebo-controlled study cited by NYU Langone Medical Center. Zinc supplements appeared to be of benefit to study participants.
