Ginkgo


Ginkgo biloba
Family: Ginkgoacea

The lovely gingko tree is the oldest living species of tree. Once it may have covered the globe, but it nearly became extinct after the Ice Age and survived only in parts of Asia. Ginkgo was a favorite plant of Chinese monks, who cultivated the tree for food and medicine.

...Ginkgo leaf has been the subject of extensive modern clinical research in Europe. Its most striking clinical effect is its ability to dilate blood vessels and improve circulation and vascular integrity in the head, heart, and extremities. Reduced circulation to the head is responsible for many of the mental and neurological symptoms of aging, including memory loss, depression, and impaired hearing.

...Large quantities of ginkgo may cause irritability, restlessness, diarrhea, and nausea and vomiting. Ginkgo extract is a prescription drug in Europe because most of the conditions that it benefits are not suitable for self-medication. If you have had a stroke or think you are prone to them for any reason, don't take ginkgo without your physician's permission.
