Ginkgo biloba is a relic plant of the Cenozoic Quaternary glacial period, known as a living fossil, it is a specialty plant in China, and more than 70% of the world's ginkgo trees grow here. Ginkgo has long been proven to have medicinal properties in China because it is rich in yellow intoxicating compounds and ginkgo lactides. They are powerful free radical scavengers that protect cells and tissues from excessive oxidation by free radicals, thereby prolonging life.
