The herb ginkgo is the leaf of Ginkgo biloba, also known as the maidenhair tree. Because this tree is the oldest species of plant known with no surviving close relatives, gingko is referred to as a living fossil. Native to China, gingko has been used in food and medicine for centuries. It is said that the elephant’s long memory is due to eating gingko leaves. You’ll enjoy the mildly sweet leaf as tea.
