0.7% of U.S. adults (1.6 million) used
ginkgo biloba

Use of ginkgo biloba by adults in the United States fell by about 46% between 2007 and 2012. Nearly 1.4 million fewer adults used ginkgo biloba in 2012 than in 2007.

The extract from the leaves of the ginkgo tree has a long history in traditional Chinese medicine. People have long used it for senility, asthma, bronchitis, and kidney and bladder disorders. However, there’s no strong evidence that ginkgo biloba is helpful for any health condition. Side effects of ginkgo may include headache, stomach upset, and allergic skin reactions, and some people may have a risk of excessive bleeding. Its raw seeds can be poisonous.
