Ginkgo biloba does not halt or slow memory loss, nor does it prevent cognitive decline, according to research funded by the National Center for Complementary and Alternative Medicine. Known as the Ginkgo Evaluation of Memory study, research was conducted over the course of seven years and involved more than 3,000 people between the ages of 72 and 96. It’s the largest and longest ginkgo biloba-related study, according to USA Today.

Initial results from the study showed that a twice-daily 120 milligram-dose of a ginkgo biloba supplement did not reduce the incidence of Alzheimer’s or general dementia. Later research, using the same results, found that ginkgo biloba had no effect on cognitive decline in older adults. Chinese medicine has used ginkgo extract for more than 500 years; sales in the U.S. were $99 million in 2008.
