What the research says

Most research on the use of ginkgo for certain conditions shows that it helps little to none. More study is needed. Conditions include:

• Dementia. Some research shows that ginkgo may ease symptoms of dementia. But it doesn't prevent or slow the progress of dementia.
• Claudication. Some small studies show that ginkgo may help people walk longer without pain. But large studies haven't shown that ginkgo helps.

Some studies on ginkgo's effect on memory suggest that ginkgo extract might improve memory slightly in healthy adults. But most studies show that ginkgo doesn't improve memory, attention, or how the brain works.
