Herbs or medicinal plants
have a long history in treating disease. In traditional Chinese
medicine, for example, the written history of herbal medicine goes back
over 2000 years and herbalists in the West have used “weeds” equally
long to treat that which ails us. We are all familiar with the virtues
of Garlic, Chamomile, Peppermint, Lavender, and other common herbs.
Interest in medicinal herbs is on the rise again and the interest
is primarily from the pharmaceutical industry, which is always looking
for ‘new drugs’ and more effective substances to treat diseases, for
which there may be no or very few drugs available.
Considering the very long traditional use of herbal medicines and
the large body of evidence of their effectiveness, why is it that we
are not generally encouraged to use traditional herbal medicine,
instead of synthetic, incomplete copies of herbs, called drugs,
considering the millions of dollars being spent looking for these
seemingly elusive substances?
Herbs are considered treasures when it comes to ancient cultures
and herbalists, and many so-called weeds are worth their weight in
gold. Dandelion, Comfrey, Digitalis (Foxglove), the Poppy, Milk
Thistle, Stinging nettle, and many others, have well-researched and
established medicinal qualities that have few, if any, rivals in the
pharmaceutical industry. Many of them, in fact, form the bases of
pharmaceutical drugs.
Research into the medicinal properties of such herbs as the humble
Dandelion is currently being undertaken by scientists at the Royal
Botanical Gardens,
in Kew, west London, who believe it could be the source of a
life-saving drug for cancer patients.
Early tests suggest that it could hold the key to warding off cancer, which kills tens of thousands of people every year.
Their work on the cancer-beating properties of the dandelion,
which also has a history of being used to treat warts, is part of a
much larger project to examine the natural medicinal properties of
scores of British plants and flowers.
Professor Monique Simmonds, head of the Sustainable Uses of Plants
Group at Kew, said: "We aren't randomly screening plants for their
potential medicinal properties, we are looking at plants which we know
have a long history of being used to treat certain medical
problems.
“We will be examining them to find out what active compounds they contain which can treat the illness."
Unfortunately, as is so often the case, this group of scientists
appears to be looking for active ingredients, which can later be
synthesized and then made into pharmaceutical drugs. This is not
the way herbs are
used traditionally and their functions inevitably change when the
active ingredients are used in isolation. That’s like saying that the
only important part of a caris the engine – nothing else needs to be
included.
So, why is there this need for isolating the ‘active ingredients’?
As a scientist, I can understand the need for the scientific
process of establishing the fact that a particular herb works on a
particular disease, pathogen or what ever, and the need to know why and
how it does so. But, and this is a BIG but, as a doctor of Chinese
medicine I also understand the process of choosing and prescribing
COMBINATIONS of herbs, which have a synergistic effect to treat not just
the disease, but any underlying condition as well as the person with
the disease. That is a big difference and not one that is easily tested
using standard scientific methodologies.
Using anecdotal evidence, which after all has a history of
thousands of years, seems to escape my esteemed colleagues all
together. Rather than trying to isolate the active ingredient(s), why
not test these herbs,
utilizing the knowledge of professional herbalists, on patients in
vivo, using the myriad of technology available to researchers and
medical diagnosticians to see how and why these herbs work in living,
breathing patients, rather than in a test tube or on laboratory rats and
mice (which, by the way, are not humans and have a different, although
some what similar, physiology to
us)?
I suspect, that among the reasons for not following the above
procedure is that the pharmaceutical companies are not really
interested in the effects of the medicinal plants as a whole, but rather
in whether they can isolate a therapeutic substance which can then be
manufactured cheaply and marketed as a new drug - and of course that’s
where the money is.
The problem with this approach is, however, that medicinal plants
like Comfrey, Dandelion and other herbs usually contain hundreds if not
thousands of chemical compounds that interact, yet many of which are
not yet understood and cannot be manufactured. This is why the
manufactured drugs, based on so-called active ingredients, often do
not work or produce side effects.
Aspirin is a classic case in point. Salicylic acid is the active
ingredient in Aspirin tablets, and was first isolated from the bark of
the White Willow tree. It is a relatively simple compound to make
synthetically, however, Aspirin is known for its ability to cause
stomach irritation and in some cases ulceration of the stomach wall.
The herbal extract from the bark of the White Willow tree
generally does not cause stomach irritation due to other, so called
‘non-active ingredients’ contained in the bark, which function to
protect the lining of the stomach thereby preventing ulceration of the
stomach wall.
Ask yourself, which would I choose: Side effects, or no site effects? It’s a very simple answer. Isn’t it?
So why then are herbal medicines not used more commonly and why do
we have pharmaceutical impostors stuffed down our throats? The answer
is, that there’s little or no money in herbs for the pharmaceutical
companies. They, the herbs, have already been invented, they grow
easily, they multiply readily and for the most part, they’re freely
available.
Further more, correctly prescribed and formulated herbal compounds
generally resolve the health problem of the patient over a period of
time, leaving no requirement to keep taking the preparation – that
means no repeat sales. No ongoing prescriptions, no ongoing problem.
Pharmaceuticals on the other hand primarily aim to relieve
symptoms – that means: ongoing consultations, ongoing sales, ongoing
health problems.
Which do you think is a more profitable proposition?
Don’t get me wrong, this is not to say that all drugs are
impostors or that none of the pharmaceutical drugs cure diseases or
maladies – they do and some are life-preserving preparations and are
without doubt invaluable. However, herbal extracts can be similarly
effective, but are not promoted and are highly under-utilized.
The daily news is full of ‘discoveries’ of herbs found to be a
possible cure of this or that, as in the example of Dandelion and its
possible anti-cancer properties. The point
is that these herbs need to be investigated in the correct way.
They are not just ‘an active ingredient’. They mostly
have hundreds of ingredients and taking one or two in isolation
is not what makes medicinal plants work. In addition, rarely are herbal
extracts prescribed by herbalists as singles (a preparation which
utilizes only one herb). Usually herbalists mix a variety of
medicinal plants to make a mixture, which addresses
more than just the major symptoms.
In Chinese medicine, for example, there is a strict order of
hierarchy in any herbal prescription, which requires considerable depth
of knowledge and experience on the
physician's part. The fact that the primary or principle herb has
active ingredients, which has a specific physiological effect, does
not mean the other herbs are not necessary in the preparation.
This is a fact seemingly ignored by the pharmaceutical industry in
its need
to manufacture new drugs that can control disease.
Knowing that medicinal plants are so effective, that these plants
potentially hold the key to many diseases, are inexpensive and have
proven their worth time and time again over millennia, why is it that
herbal medicine is still not in the forefront of medical treatments,
and is considered by many orthodox, medical professionals and
pharmaceutical companies as hocus-pocus,
hmmm?
