Author:

Ginkgo biloba, lauded as the "brain herb," according to University of Maryland Medical Center, is one of the oldest living tree species, and the leaves are available in capsule, tablet, liquid extract or dried herb form, reports LiveStrong.com.

The plant can improve mood and increase attention in healthy subjects, according to a December 2010 review article in the Life Sciences Research Organization, Inc. issue of Nutrition Reviews titled "Do Specific Constituents and Supplements Affect Mental Energy?" reported Newswise. The UMMC ginkgo biloba overview states ginkgo shows signs it can enhance memory in older adults and that laboratory studies prove "gingko improves blood circulation by dilating blood vessels and reducing the stickiness of blood platelets."

Among the best-selling herbal medications in Europe and the United States, "it consistently ranks as a top medicine prescribed in France and Germany," states the UMMC ginkgo biloba overview.

LiveStrong.com points out that Anthony J. Cichoke references the "use of gingko in Native American medicine for treating and alleviating depressive symptoms," in his book "Secrets of Native American Herbal Remedies." Gingko contains compounds called flavonglycosides and gingkolic acid, which help to fight depression, Cichoke states, according to LiveStrong.com.
