Ginkgo biloba, or maidenhair, is a tree native to China that has been grown for thousands of years for a variety of uses. Because it’s the only surviving member of an ancient order of plants, its sometimes referred to as a living fossil. While its leaves and seeds are often used in traditional Chinese medicine, modern research primarily focuses on ginkgo extract, which is made from the leaves. Ginkgo supplements are associated with several health claims and uses, most of which focus on brain function and blood circulation.
