Ginkgo Leaf Pin
If you have been to the Maryland Historical Society, you would have noticed the ginkgo trees lining one side of the Meyerhoff Courtyard on Park Avenue. The ginkgo tree is not native to North America, but comes from China. The tree is prized for its ability to withstand the hardest of environments, like a city sidewalk. Ginkgo extract has been used in China and Japan against asthma and severe allergic inflammations.
