Ginkgo Biloba Spiegazione
has been known as the oldest living species of trees with
its roots as far as 270 million years in the world. Even
the single living tree can be as old as 3000 years or so,
one is reported in Shandong province in China. They can
be as tall as 165 feet.
The Ginkgo Biloba
tree has long angular branches, with strong deep rooted
roots which make it stable in extreme snow and windy conditions.
A combination of resistance to disease, insect-resistant
wood and the ability to form aerial roots and sprouts makes
ginkgos very long-lived.
The tree is not ever green, the leaves turn deep yellow
during winters and fall considerably, in winters it is no
more than bare branches but in spring and summers it is
in full bloom and have the pollination
as well. The leaves are fan shaped which have dichotomous
The leaves are usually 5-10 cm (2-4 inches), but sometimes
up to 15 cm (6 inches) long. The trees have separate sexes,
male and female. They fertilize through pollination.
Though the birth rate is very slow, but their long living
property has been able to make it survive through thick
and thin. Their strength and resistance came in notice specifically
in Hiroshima, Japan where four specimens of trees were found
even after the drastic blast of an atom bomb.
The general dosage in adults is 80 to 240 milligrams of
a 50:1 standardized leaf extract taken daily by mouth in
2 to 3 divided doses has been used and studied (standardized
to 24% to 25% ginkgo flavone glycosides
and 6% terpine lactones).
Other forms used include tea (bags usually contain 30 milligrams
of extract), 3 to 6 milliliters of 40 milligrams per milliliter
extract daily in three divided doses, and "fortified"
foods. Ginkgo seeds are potentially toxic and should be
avoided. Like seeds the intra venous solution is also harmful.
Tebonin is a german
product of Ginkgo Biloba that was given intravenously and
had severe side effects and hence has been banned.
