Many people
put their faith on homeopathy to cure their ills, but that is all it is –
faith. Homeopathic remedies are pseudo-medicines that can have no physical
effect on the human body whatsoever.
Does
homeopathy really work?
There are
really two questions here, one being whether homeopathic medicines and
treatments produce clinical benefits for patients, but the other being whether
patients feel better after having been treated by such medicines and
treatments. This may sound like two ways of saying the same thing, but it is
not. I am quite prepared to give a “No” answer to the first question but a
“Yes” answer to the second.
What is
homeopathy?
If we examine
the clinical claims of homeopathy, they do indeed sound extraordinary. Working
on the “hair of the dog” principle (that to cure a hangover you need to drink a
small quantity of what it was that made you drunk in the first place),
homeopathic medicines consist of highly diluted doses of the substance that may
have caused your disease.
The principle
is known by homeopaths as “like cures like”. In itself, this sounds highly
unlikely, but the degree of dilution is so extreme that it becomes very hard to
believe that the substance in question can have any effect on the body at all.
Indeed, some of the claims of dilution would require a single molecule of a
substance to be surrounded by more atoms than exist in the entire Universe!
On the face
of it, this sounds to be nothing short of absurd. How could a treatment
prepared on this basis (if it were indeed possible to create such a medicine,
which is clearly not the case) have any effect at all? But that is not the
whole story. What turns a dilution into a homeopathic remedy is another
principle of homeopathy, namely that “water remembers”. The fact that the water
you ingest has been in contact with the active substance is what gives rise to
the cure. This is an enormous claim, especially when you consider that water
gets around a lot, and the water that comprises my cup of coffee has been drunk
and excreted countless times before, and been in contact with any number of
substances, both benign and not. Just which of those millions of memories is
supposed to effect my cure?
It gets even
more ridiculous than that!
We must not
forget “succussion” either. A homeopathic medicine only acquires its power if
it undergoes a process that involves the vessel containing the remedy being
struck ten times against “a hard but elastic object”. This practice goes back
to the founder of homeopathy, the 18th century German doctor Samuel
Hahnemann, and is still at the heart of homeopathy today. Without the ten
strikes, the remedy does not work.
So, if you
ask yourself how homeopathy can work, in purely clinical terms, the answer must
surely be that it cannot. Nothing is being done to the body that can possibly
have any effect on it whatsoever.
If it works,
what is going on?
Countless
people claim to have had their illnesses cured by homeopathy, and it would be
perverse to claim that they must all be either lying or deceiving themselves. I
am quite prepared to accept what they say. However, I do not believe that it is
the physical nature of the treatment that is doing the trick as much as the
psychological effect of actually being treated.
The
psychology of “mind over matter” takes many different forms. Many fascinating
studies have been performed over the years into the “placebo effect”, namely
how a patient’s condition is improved when they believe that they are being
treated with real medicine when it is in fact only a harmless sugar pill (or
equivalent) that they are being given. It has also been shown, for example,
that when the same pills are packed in plain boxes and in colourful ones with
brand names all over them, the latter produce better results.
Proper clinical
trials, carried out with all necessary precautions by independent scientific
institutes, have shown consistently that homeopathic remedies perform no better
than placebos, but that is not the same as saying that they entirely useless,
because placebos often work remarkably well in any case.
Don’t
discount placebos
Medical
practitioners have always known that a patient with a positive attitude towards
their condition will often do better than someone who is pessimistic, whatever
treatment is offered. Doctors know that the time spent talking with a patient
and discussing their illness is frequently more effective than any medicine
that is prescribed. They also know that when a patient insists on leaving with
a prescription in their hands, it is usually better to give in to their demand,
because if someone really believes that a medicine is what they need, then even
a box of sugar pills will be better than nothing.
One problem
with the health system, at least in the United Kingdom, is that regular
medical practitioners cannot give as much time to their patients as they would
like, with seven minutes being the average time of a consultation. However, people
working in alternative medicine, such as homeopaths, are free to give as much
time as they want to discussing a patient’s needs, going into their family
background, social circumstances, medical history, and much more besides. All
this focused attention on the patient is far more effective, psychologically,
than any pill that is prescribed.
Another factor,
hinted at above, is the self-belief of the patient. Very often, a patient goes
to a homeopath after having been, as they see it, let down by conventional
medicine. The homeopath is not seen as the last hope, but as a beacon of hope.
The patient wants the treatment to work; they are, after all, paying good money
for this consultation, and most people do not throw good money after bad by
spending it on causes that are lost from the start. Many first visits to a
homeopath come after a recommendation by a friend who reports good results;
this again is likely to inspire hope and a positive attitude.
Can
homeopathy always be trusted?
Homeopathy
does not always work, and I would personally be very reluctant to trust a
serious condition to homeopathic treatment. Although “miracle cures” are
sometimes reported, it must be remembered that “miracles” do sometimes happen
and, by definition, the cause of a miracle cannot be determined with certainty.
I am referring here to the statistical evidence of the 1% of terminal cancer
patients who are still alive five years after 99% have died; there is no single
factor that distinguishes the survivors from the deceased.
We should not
be swayed by the claims for potentially miraculous cures due to homeopathy,
because there is no way of knowing that it was the homeopathy that did the
trick. We must beware of falling into the logical trap of “post hoc ergo
propter hoc”, meaning that because A happened after B, then B must be the cause
of A.
It is
disturbing to read of patients being persuaded by homeopathic practitioners to
abandon conventional treatments for such conditions as advanced heart disease
and cancer, and dying much sooner than they should have done. Having faith in a
treatment can only take you so far, and, in such circumstances, I would prefer
on balance to favour science against irrational belief.
That said,
and for the reasons advanced above, I do think that homeopathy and other
alternative therapies have a role to play, and that they can produce positive
outcomes in certain circumstances, but by no means all. The psychological
aspects of medicine are of considerable importance, because the human being is
not just a machine.
It all seems
to be summed up very well by the words of the famous song by Oliver and Young:
“It ain’t what you do, it’s the way that you do it; that’s what gets results”.
