Evidence

Research on ginkgo use for specific conditions shows:

• Dementia. There isn't enough evidence to support the use of ginkgo to prevent dementia or treat people with mild cognitive impairment.
• Claudication. A review of the research suggests that taking ginkgo has no significant benefits for people with this condition.

Ginkgo's effect on memory enhancement has had conflicting results. While some evidence suggests that ginkgo extract might modestly improve memory in healthy adults, most studies indicate that ginkgo doesn't improve memory, attention or brain function.
