Ginkgo
Ginkgo biloba

Interestingly, this "herb of longevity" happens to come from the oldest species of tree in the world today. Ginkgo biloba (a.k.a. "Maidenhair") trees have grown in the Orient for more than 200 million years! One of these stately trees can live well over 1000 years and grow up to 100 feet tall. Chinese have used ginkgo for thousands of years to help cope with aging by supporting mental clarity and memory. Ginkgo supports healthy blood flow, especially to the brain. An antioxidant, ginkgo may also protect against the deteriorating effects of free radicals.
