Habitat
Perennial deciduous tree, native to eastern China. Ginkgo
Biloba is the oldest
species of tree still living on the earth and can be traced back more than 300 million
years. For this reason, ginkgo is often referred to as "the living fossil." A
species of the family Ginkgoaceae, it is the only one of the family known to have survived
the Ice Age. Cultivate with care, grow in gallon pots for a year or two before
transplanting seedlings to their permanent location in the garden or landscape. Plant one
for your Great, Great, Great, etc. grandchildren. They grow as tall as 70 feet and live
(some say) a thousand years. When male and female trees are grown together, the female
produces yellow plum-like fruits in autumn which when ripe look (strangely) like little
brains! When these fall to the ground and are squashed they give off a truly disgusting
odor (like rancid butter) but contained within the fruit is a seed which is considered a
delicacy in China where it is usually roasted before being eaten. The leaves are green to
gold, fan-shaped, petioled, with many radiating veins and about 4 to 5 inches wide. Gather
fresh green leaves in summer, dry for later use.

Properties
Extracts of the fruit and leaves of the Ginkgo tree have been used in China
for over 5,000 years. Ginkgo Biloba has been historically used in alternative medicine for
Heart disease, Kidney disorders, Alzheimer's, Asthma and as an energy builder. Recently
western researchers have been studying ginkgo biloba as a treatment for senility,
hardening of the arteries, and as a treatment for oxygen deprivation. In over 34 human
studies on Ginkgo it increases the body's production of the universal energy molecule
adenosine triphosphate, commonly called ATP. This activity has been shown to boost the
brains energy metabolism of glucose and increase electrical activity. Scientists also
discovered that ginkgo contains an abundance of useful compounds including the
antioxidants Vitamin C and carotenoids, but it is the flavanoid compounds collectively
known as "ginkgolides" that are the most remarkable. The ginkgo flavonoids act
specifically to dilate the smallest segment of the circulatory system, the
micro-capillaries, which has a widespread affect on the organs, especially the brain.
Researchers have also reported that Ginkgo extracts effectively increase blood circulation
and increase oxygen levels in brain tissues. Ginkgo is also a powerful antioxidant that
prevents platelet aggregation inside arterial walls, keeping them flexible and decreasing
the formation of arteriosclerositic plaque. It
has also been shown to help restore circulation to areas of the brain damaged by stroke.
Ginkgo has a positive effect in Dementia cases, fighting free radicals in the blood
system, protecting against chromosomal damage (proven with Chernobyl workers).
Ischemia-induced spinal cord injury protection, heart muscle ischemia and reper-fusion
injury protection. Protection against retinal damage, helping with tinnitus, headaches,
vertigo, hearing loss, depression, allergies, atherosclerosis, cardiac arrhythmia,
diabetic peripheral disease, eczema, glaucoma, impotency, retinitis, to treat asthma, to
aid digestion, and bring back sexual energy
as well as treating early stages of Alzheimer's disease. The brain is one of
the most metabolically active tissues in the human body. It uses a great deal of energy
which requires a steady supply of oxygen and glucose. Unlike most other tissues, the brain
has very little energy reserve which makes it extremely susceptible to the effects
of poor blood supply. When circulation is inadequate, the brain cannot function at its
full capacity. The big news for ginkgo came in October 1997 when the Journal
of the American Medical Association published the results of a study that confirmed that
ginkgo had a positive effect in cases of dementia. They used only patients whose main
problem was mental impairment, whether someone had termed it Alzheimer’s or not. They
used every control imaginable and rated progress on three different scales to make sure
that their results were accurate. Researchers even went so far as to switch everyone from
the placebo to the real medicine and vice versa in the middle of the study. There is no
doubt about it. Ginkgo stopped the progress of the disease in most cases, and many cases
reversed the damage. A Swedish study showed that ginkgo improved
the distance-vision of people who already showed signs of degeneration in the retina. The
disease macular degeneration, a leading cause of blindness, is strongly related to
hemorrhages in the fine blood vessels in the eye, possibly due to oxidative stress. By
strengthening the tiny blood vessels in the eye, and by acting as an antioxidant, ginkgo
provides a double whammy against eye diseases. It eliminates waste material and inhibits
the clumping of blood platelets and prevents circulating platelets from sticking together,
which contributes to heart problems, strokes and artery conditions. Ginkgo is an
adaptogen herb, which helps the body with stressful situations. It is also helpful in the
treatment of allergies, Alzheimer's disease, anxiety attacks, arthritis, ADD, circulatory
disorders, cancer, coughs, depression, dizziness, equilibrium problems, headaches, heart
& lung problems, memory loss, mood swings, muscular degeneration, tinnitus, toxic
shock syndrome, varicose veins, vascular impotence & vertigo. Studies have shown that
the length of time a person uses this plant leaf is very important. With ginkgo, the
effectiveness may not be felt for twelve weeks. While most people note some improvement in
just two to three weeks, others take longer to respond. Ginkgo biloba extracts are
relatively considered safe and free of side effects, though taking very large doses may
lead to diarrhea, nausea and vomiting, which can be controlled by reducing the amount
consumed. Those taking
blood thinners should consult with their physician before taking ginkgo biloba in high
doses, due to their blood thinning tendencies. It is also advisable to discontinue use
prior to surgery.
Folklore
Ginkgo is strong in legend and lore of China, and has been lovingly adopted
by most cultures in the temperate regions of earth. Darwin called it a living fossil, the
only species remaining of a genus which flourished in the time of the dinosaurs. Gingko is
held or carried to help improve the memory. A mild tea prior to bedtime will help to
remember dreams during sleep.
