THE IMPORTANCE OF
CLINICAL EVALUATION
Natural Products
Clinical
trials and studies are rarely found in natural or nutritional
products. This is primarily due to the fact that these
natural occurring compounds already exist in nature
and
there is nothing new or novel to patent. Due to this,
companies will not incur this massive expense to run
trials
as they do not have the exclusivity protection of a patent,
in which to recoup their investment. This has unforeseen
consequences as certain important criteria are therefore
never determined.
1. Is the product toxic
2. Does it work
3. Does it interact with other compounds.
Qina has clinical trials that prove all the above and
more.
Problems facing Natural Products
There are
some major problems with natural or nutritional products
and that is the lack of clinical data supporting efficacy,
toxicology, interaction and processing quality.
As natural
and nutritional medicines cannot be patented,
manufacturers may patent the extraction
process or use terms like "proprietary blend"
to hide the exact composition of the ingredients to protect
their formulation. This unfortunately opens this market
to all forms of abuse with many product duplications
and pricing discrepancies, depending on whether the
marketer
is basing their product on quality or pricing.
Efficacy
or does it work.
There are daily allowance guidelines for vitamins and
minerals that were detailed back in the 1930's and to
date have changed very little. Many believe that the criteria
in determining these maximum allowable quantities was
to circumvent a healthy adult male from developing Rickets.
Another report states that these daily allowance guidelines
were set so low in order to perpetuate disease thereby
ensuring the growth of the pharmaceutical industry and
providing a constant flow of patients into an ever increasing
pool of doctors.
We know
that good nutrition from food can help prevent many
diseases, but can these natural occurring components
generate the same result after being processed. Vitamin
C for example has undergone 17 chemical changes from
its original form to ascorbic acid.
Calcium plays a major role in bone density. But does
calcium supplementation offer an effective alternative.
Marketers embarked on a major advertising
drive to prevent Osteoporosis by supplementing
with calcium.
The two misleading facts here are that osteoporosis is
not as big a problem that has been portrayed and only
affects 3-4% of people in their old age. Secondly there
are so many forms of calcium, most of which have
never been proven to penetrate into the cell in
order to affect change. So what you have is high levels
of calcium
floating in the blood stream that will eventually develop
into calcification of the joints.
Toxicity
This is more apparent when taken in high doses. A misunderstanding
is the thinking
that because a substance is natural, it is safe without
side effect... this is untrue.
High dose medication especially
herbal
products
can,
and
do lead to liver toxicity. A newly discovered ingredient
in weight loss products saw a flood of patients arriving
at Canadian hospitals ....
Interaction
Heart patients on Warfrin to thin their blood, should
avoid taking White Willow bark extract which is the natural
form of aspirin which also thins the blood. Insufficient
studies have been done on the interaction of natural medicines
and drug interactions.
Processing
This area is where there is great concern in the quality
of the product or extract. Aloe Vera is a product
that
is open to abuse. Firstly there is the terminology "aloe
vera" which is derived from the plant Aloe Barbadensis
Miller. Products use the the picture of the plant
and
state it contains aloe, but is not aloe vera. Concentrations
come in 1:1 up to 200:1 and one never knows the exact
content the product contains. And perhaps the most important
is the processing of the leaves. One never knows if
the
particular processing method used was able to keep all
the original symbiotic elements intact. If a manufacturer
runs short of stock and has to use a different supplier,
the reality is that the product has now changed, as the quality and
bio
availability from a different source has not been checked. The efficacy of plants
is dependant on many factors. Where they were grown,
when
they are picked, from which part of the plant. How were
they transported and stored and how they were processed.
In
conclusion
Qina has satisfied all the criteria to ensure a safe
and effective product proven by clinical and scientific
studies
Pharmaceutical
Drugs
Pharmaceuticals
on the other hand or synthetic compounds which
do not occur naturally. For these a patent is available
and clinical studies are imperative due to safety and
efficacy concerns.
To explore all the variables and designs of all the clinical
studies and trials available is a huge undertaking, and
the depth and scope of them is a subject in themselves.
The first step starts with a pre clinical laboratory study,
to determine efficacy and pharmacokinetics (what the body
does to the drug). 90% of drug trials fail this stage.
If successful they move onto animal studies usually in
rats or mice. The failure rate at this stage is also
very high. And finally they move onto human trials. This is
where the highest failure rate is and is also the most
costly.
Due to these high costs, which can run into millions
of dollars, the drug manufacturer is assured of a patent
protecting them for the next 20 years. When the patent
runs out the drug can be made by other companies, and
is called a generic. If manufactured in the original
manner
the only difference between a generic and the original
is the brand name.
All pharmaceutical
drugs have adverse side effects, primarily because these
synthetics are not supposed to be in our system. This
has become more evident of late. In the USA
the 4th leading killer is "Adverse Drug Reaction",
in other words,
the medicine is killing the patient. However the
doctor patient trust factor remains firmly intact.
Interestingly enough in the last 13 years only 6% of
new drugs coming onto the market are novel and new,
the other
94% are reformulation's of the older drug. This in
no way means that the revised version is better, in
fact
in many cases they have added side effects, but the
drug companies want to ensure market share and continue
making
unrealistic profits. At the end of the day drug companies
are not owned by loving caring people, they are owned
by investors and shareholders who demand improved profits.
If they do not perform, their investment will shift
elsewhere.
The
war between natural and pharmaceutical products
Kava Kava was taken off the market due to one person showing
signs of liver toxicity. On close examination he was taking
10 times the daily dose, but this did not affect the resulting
world wide ban. When one takes a look which product Kava
Kava was in competition to, it's Prozac, no guess who
was behind that.
Another excellent naturally occurring compound called
Policosinol, which is derived from sugar cane. It competes
with a statin drug called Lipitor which posted profits
of $16.8 Billion in 2006. All of a sudden a new study
is done showing that Policosinal does not work, and this
information is posted to every medical practitioner
world
wide. Now most doctors have absolutely no understanding
of natural medicines, so when you as the patient, ask
if
it is safe to take, he will reply "you're wasting
your money." This is based on the information he
receives from peer reviewed medical journals. What was
never told to the doctor is that the original trials
undertaken used sugar cane as their source and the
new debunked trial
source was from Yams or beeswax. The end result is that
the damage has been done.
This type if disinformation campaign is evident whenever
a natural medicine competes with a profit making pharmaceutical
drug.
