Ginkgo biloba is the oldest living tree species with an indestructible nature. A single tree can live as long as 1,000 years. The Ginkgo tree is a symbol of unity of contrasts, hope, love and long life. Because of the natural protection against bacteria, pollution, insects and fire, these trees are planted in urban areas. Ginkgo has a positive effect on memory and thinking, by restoring a better blood flow and allowing improved use of oxygen. Ginkgo increases blood circulation, which is important in maintaining our energy level.
