Ginko Biloba has been shown to be more effective than vasodialators (and placebo) as a long term solution to tinnitus. Some improvement noted by 60% of recipients with some permanence indicated. Tinnitus is a fact of aging for many, similar to losing the ability to see detail up close. This is a result reduced vascular health and elasticity in addition to damage from environmental factors. Many cases of tinnitus in response to medications are temporary and resolve (to some degree) over time but by age 60 10% of all people complain of tinnitus as a permanent condition. Mine comes and goes, medication exacerbated it but I feel mostly it's due to damage from my past. Things that seem to help my vascular health overall (and high blood pressure) seem to help the condition.
