THE ROLE
OF
GINKGO
LEAVES
ON DISEASE
PREVENTION
The leaves
of
the Ginkgo tree are
well
known to the Chinese.
Recently,
much research have also been done
on
the exlract
of
the
leaves
-
the
main
ingredients
are
the flavonoids
and
the
terpenoids. Relaxation
of
vessels,
im-
proving micro-circulations,
preventing
platelets in
the
blood from clumping,
reducing
blood
viscosity, arterial resist-
ance
(and
the blood
pressure) were
noted.
Coronaries, angina and
high
blood
pressure
may
be
prevented.
Fat
metabolism
is
improved, high-density
lipoprotein
raised
and cholesterol
in
the blood,
reduced.
Since'free
radicals"
in
the body are relaled to ageing
and
cancerous changes, the ability
of
these
extracts
to
enhance
the
action
of
superoxide dismutase
(SOD)
to
get
rid
of
free
radicals in the blood
is
valuable.
A
protective action
on the
heart and the
brain
tissues
is demon-
strated even in areas with vascular
insufficiencies due
to
coronaries or
stroke. Other advantages
studied
were prevention of Parkinson's disease,
senile dementia and enhancement of
immunity. Even
memory improvement
and
liver protection functions
have
been
claimed.Thus, such
leaves have
a great potential in modern
disease
prevention.
