Ginseng and Ginkgo Biloba

There are many nutritional supplements that claim to provide benefits to the mind and body. Ginseng and Ginkgo Biloba are two of the more popular supplements.

Ginseng
Ginseng is an herb that comes from the root of the ginseng plant. It has been used in China, Japan, and Korea for centuries and has been shown to improve memory and mental performance, especially if taken in combination with ginkgo biloba. Additionally, ginseng may help increase the body's resistance to stress [ For more on 'stress' go here: http://www.braingle.com/mind/534.html ].

Ginkgo Biloba
Ginkgo biloba is an extract taken from the leaves of the ginkgo tree. Many studies have shown it to have beneficial effects. Its most important benefit is that it increases blood flow to the brain, which improves short and long-term memory as well as reaction time and mental clarity. In addition, ginkgo biloba may help regulate neurotransmitters [ For more on 'neurotransmitters' go here: http://www.braingle.com/mind/690.html ] and oxygen levels in the brain. Ginkgo can be found in pill form and is sometimes used as an ingredient in energy drinks. Some studies also suggest that ginkgo biloba can somewhat benefit people with Alzheimer's disease [ For more on 'Alzheimer's disease' go here: http://www.braingle.com/mind/361.html ].

If you have blood circulation problems or are taking anti-coagulants such as aspirin, you should probably stay away from ginkgo. People taking anti-depressant drugs known as MAOIs and pregnant women should also stay away from ginkgo biloba.
