Ginkgo Biloba

Herbal Supplements

The Basics
Ginkgo biloba is often referred to as GBE (Ginkgo Biloba Extract). Much is known about GBE due to extensive research. Although ginkgo biloba is a tree, the leaves are used to make standardized GBE preparations.

This herb benefits circulation by strengthening blood vessels and reducing blood platelet stickiness. Improved circulation promotes oxygenation and benefits the brain (nervous system), limbs, and may help impotence due to impaired blood flow. GBE's antioxidant properties help to protect the body from the effects of aging.

More specifically, GBE helps memory loss, vertigo, tinnitus (ringing in the ears), headaches, depression, leg cramps, asthma, eczema, and some heart and kidney disorders. Researchers are investigating the benefits of GBE in treating Alzheimer's disease.

While I have had some patients that describe improvement of their symptoms from various dietary supplements, there is little scientific evidence that they work. In small amounts, I do not believe they are harmful, but I am not convinced they are any more effective than adhering to a healthy, well-balanced diet. On the contrary, there is strong scientific evidence showing that patients with a poor overall nutritional status have higher complication rates from surgery.
