The Gingko or tree of the forty shields, is a unique tree in the world, without living relatives. It contains a single species, Ginkgo biloba. For centuries, if not millennia, it has been used for its therapeutic actions, especially in traditional Chinese medicine, and the leaves of the tree are used in modern herbalism. From its leaves an extract is obtained that has flavonoids (ginkgoloids and heterosides) that when ingested increase central and peripheral blood circulation, and as a consequence irrigation of organic tissues becomes more efficient. Ginkgo is often used for memory disorders that occur, for example, in Alzheimer's disease. How to use Take one to three tablets daily, preferably with food. Warnings: None taking it according to the recommended use
