You have probably seen these trees lining streets and neighborhoods. The ginkgo is commonly planted as an ornamental tree.

The ginkgo is well known for being a “living fossil.” It is considered one of the oldest tree species in the world and has not changed much from it’s 200 million-year-old ancestor.

There are both male and female ginkgo trees but nurseries usually only sell male trees. The female tree produced a fruit that has an awful smell to it. Female trees are often avoided in cities and neighborhoods because of the smell. A branch from a male tree that is grafted onto a female tree will cause the female to produce fruit.

In China, where the ginkgo tree is native to, it is a symbol of longevity and vitality. Ginkgo trees are often planted near and around temples, though there are many of these trees that predate the temples built around them.

The ginkgo is a very tolerant tree. It is favored in cities because it is easily grown in polluted areas. It can also survive severe damage from lighting and it’s even been said that ginkgos and cockroaches were the first to thrive in Hiroshima and Nagasaki after WWII.

Ginkgo has been used medicinally in China for hundreds of years. In China, the seed is primarily used while in the west the leaf is used instead. It is best known in the west for its ability to aid in circulatory problems.

There have been many studies done on gingko however, there is no strong evidence that ginkgo may improve health or prevent various ailments. Since ginkgo contains flavonoids and terpenoids it is believed that it could potentially help with  Alzheimer’s, anxiety, depression, circulatory problems, and more. More research is being done on ginkgo but there is no conclusive evidence that ginkgo can aid in or prevent health issues.
