Ginkgo biloba fastigiata, Maidenhair tree (Ginkgoaceae)

Gingko biloba is the oldest living tree species with at least a 200 million year history. It was present in the time of the dinosaurs and predates the Mesozoic era. Charles Darwin refered to it as a living fossi in 1859. Ginkgo trees were once widespread in Europe and North America, but were destroyed in most regions during the Ice Age, surviving only in certain regions of China. They would be extinct today had it not been for the preservation efforts of some Buddhist Monks. Ginkgoes are extremely hardy and resistant to environmental pollutants. Their leaves are light green in the spring turning bright yellow in the fall.

The Ginkgo is dioecious - meaning that male and female parts are contained in separate flowers that grow on separate trees. Most ginkgos do not flower until they are over 20 years old. The male flowers are 1" long catkins. The female flowers are grouped in pairs with two green ovules. The female tree produces a fleshy yellow fruit that appears in autumn.

The Chinese have used it in treating asthma and cerebral disorders for at least three thousand years. Though long used as a medicine in its native China, its therapeutic actions have only recently been researched. Traditionally known as an anti-microbial and anti-tubercular action, it has now been shown that ginkgo has a profound activity on brain function and cerebral circulation. This action is useful to prevent dizziness, tinnitus, short-term memory loss, depression and other symptoms related to poor brain circulation. Its effect on poor circulation also used to treat other related disorders like diabetes, hemorrhoids and varicose veins.
