Ginkgo Biloba: Nature’s Brain Tonic
Ginkgo biloba has gained a reputation as a brain tonic, to help improve memory. New studies indicate Ginkgo biloba may even be helpful in the treatment and prevention of Alzheimer's.
Nicknamed as a "living fossil", the Ginkgo biloba is a unique tree that remains unchanged through the passage of time. It has been in existence since the time of the dinosaurs and therefore considered as the sole living link between the lower and higher plants.
The Chinese, and later the Japanese, who called it Ginkyo, meaning "silver apricot" referred to it as a symbol of longevity because of its history.
The Plant
The Ginkgo biloba is classified under gymnosperms (meaning "naked seeds") for its seeds are not enclosed in a ripened fruit but are protected only by a fleshy seed coat. The Ginkgo biloba is distinguished from other gymnosperms by its fan-shaped foliages. Its leaves are bi-lobed, hence the name "biloba."
The Ginkgo biloba has branches that may be long or short growing at nearly right angles. Because of the highly variable branches of the Ginkgo, older trees are usually irregular in form. The buds of are mounded with distinct form and leaf scars.
The short leaf shoots clustered near the tip of the branch produce the seeds and the pollen.
The leaves of the Ginkgo biloba are its most recognizable feature. They are 5-8 cm wide and sometimes even twice as broad as that. They also resemble the leafshape of a Maidenhair fern (Adiantum), hence it is often referred to as the "Maidenhair tree."
During fall, the leaves turn a brilliant gold making the people in the olden times think it precious; so much so that they called it "tree of forty gold crowns" for that was how much it cost in former times.
A Ginkgo biloba tree can grow up to about 30 or 40 meters (100 ft.) in height and spread its foliage across 9 meters of space. The trunk can be as wide as 4 meters (13 ft.) in diameter and in open areas, can even become wider than that. The girth of Ginkgo bilobas that grow on temple grounds are about 10 meters in diameter.
Health Benefits
Ginkgo biloba has the ability to increase blood flow to the brain and throughout the body's network of blood vessels. These vessels are very important since they supply the blood and oxygen to the organs. Because of this ability of the Ginkgo biloba tree, it promotes increased metabolic rate, regulates neurotransmitters, and boosts oxygen levels in the brain.
In the last three decades, Ginkgo biloba has been proven to prevent many problems and ailments throughout the entire body. It is gaining recognition as a brain tonic, enhancing the memory as it positively affects the vascular system, especially the cerebellum. Ginkgo biloba is also used as treatment for vertigo, tinnitus (ringing in the ears), and a variety of neurological disorders and circulation problems.
Because of its strangely soothing effects on the neurological aspects of the body, it is also believed to help counteract the effects of aging, including mental fatigue and lack of energy.
Preparation Tips
Ginkgo biloba was used in the ancient times as a water-based herb so it may be effective as a tea. However, some studies have suggested that Ginkgo biloba doesn't break down in water. Fortunately, the herb is available in capsules, tinctures, or powdered form. As a tea, it blends well with sage, rosemary, and Gotu kola.
Seeds from the ginkgo biloba tree are also used in cooking. However these seeds can lead to poisoning if taken in large quantities. Other side effects of ginkgo biloba include increased risk of bleeding, nausea, vomiting, diarrhea, headaches, and dizziness.
