Policosanol is
an interesting chemical
constituent, as it
is derived from several different
types of plants. It is
primarily used for
treating irregularities in blood
lipids, such as cholesterol and
elevated triglycerides.
Moreover, because of its benefits for
the cardiovascular system,
policosanol is used by people
with heart disease, intermittent
claudication, elevated blood lipids,
and for preventing atherosclerosis.
Policosanol is
derived mainly from sugar cane and
wheat germ oil. It is a mixture of
the wax-like alcohol chemicals found in these
plants. Biologically, these are
typically long carbon chains, being comprised of such compounds as
octacosanol, tetracosanol,
hexacosanol, heptacosanol,
nonacosanol, triacosanol,
dotriacontanol, and tetratriacontanol.
[1,
2] The main waxy
alcohol ingredient, octacosanol,
makes up roughly 60 to 70% of
policosanol. Oftentimes, policosanol is incorrectly referred
to as octacosanol. A proprietary
form of policosanol has also been
developed using beeswax as the
source; it is purportedly more
stable than other forms of
policosanol.
Policosanol is
used mainly for treating elevations
in cholesterol. It works by slowing
the synthesis of cholesterol in the
liver and by hastening the breakdown
of low-density lipoprotein (LDL, or "bad")
cholesterol. [3,
4] Policosanol is also useful for
lowering platelet aggregation due to
certain clotting stimuli. [5,
6] When
compared to the abilty of aspirin to
decrease platelet aggregation,
policosanol was deemed as effective.
[7]
In treating high blood levels of
lipids (fats), policosanol is
effective at lowering cholesterol
and LDL as previously mentioned,
and can increase the "good"
cholesterol, or high-density
lipoprotein (HDL) levels. In several
studies, policosanol decreased LDL
cholesterol by 11% to 31% and raised
HDL cholesterol by 7% to 9%. [8-10]
Also, policosanol's
cholesterol-lowering effect was
compared to two pharmaceutical drugs
and was shown to be just as
effective as these prescription
medications. [11,
12]
For treating intermittent
claudication, policosanol was
shown to improve the distance which
those affected were able to walk
(this is a common efficacy
measurement in this condition)
without experiencing pain. [13]
For treatment of
hypercholesterolemia and
intermittent claudication, the
average dose is 10 to 20 milligrams
per day. [13,
14]

Policosanol
Deficiencies and
Toxicities |
Policosanol
Deficiencies
There are no known states of
deficiency; policosanol is not a
substance that occurs normally in
humans.
Policosanol Toxicity
Policosanol is considered safe when used in
accordance with proper dosing
guidelines. [15,
16] Some
reported side effects from taking
policosanol include: insomnia,
daytime sleepiness, irritability,
dizziness, stomach upset, skin rash,
nose bleeds, and increased appetite.
[7]
Because this substance harbors the
ability to inhibit
platelet aggregation, it may
theoretically increase risk of
bleeding in those already taking a
pharmaceutical anticoagulant
medication. Caution should be
exercised when taking this and any other blood-thinning
medications.
