The ginkgo leaf comes from the ginkgo tree, known scientifically as Ginkgo biloba. This tree is one of the oldest living tree species, dating back over 200 million years. Ginkgo leaves are fan-shaped and have a unique, vibrant green color in spring and summer, turning a bright yellow in autumn. Ginkgo leaves are often used in traditional medicine and are believed to have various health benefits, including improving memory and circulation. They contain antioxidants and other compounds that may help protect cells from damage. Ginkgo supplements are popular in many parts of the world for these potential benefits.
