Correct Answer : C.
Studies support the use of ginkgo biloba for tinnitus, dementia, and intermittent claudication. Those examining its use in patients with dementia are of the highest quality, and consistently demonstrate that ginkgo is more effective than placebo in delaying cognitive decline. The studies examining its use in tinnitus, claudication, and cognitive improvement in people with normal mentation are limited by bias and small numbers of studies with inconsistent results. Ginkgo is not appropriate for the treatment of benign prostatic hyperplasia.
