Imagine being handed a
fake(假的) pill by your doctor to treat an
illness. You would be pretty mad if you found out the pill was not a real
medication, wouldn't you? Better yet, imagine the doctor tells you the pill is
fake. At that point, you'd probably question whether the doctor even knows his
staff at all. But wait, there's more to the story.
Ted Kaptchuk of
Harvard University conducted an experiment to help treat irritable bowel
syndrome(肠过敏性综合征) pain in 2010, in
which he clearly marked the patients 'pills as "placebo"(安慰剂), or fake. Unbelievably, the group that was aware that it was
receiving the placebo reported significant improvement in their condition.
Many of you probably
know about the placebo effect. It's the idea that giving patients an
ineffective treatment -such as a sugar pill-for their condition might actually
produce beneficial effects.
Why does it work? We
don't really know. One theory is that the placebo causes your brain to have a
response that flows down to other parts of the body. Placebos presented as
stimulants (兴奋剂) tend to increase the
heart rate and blood pressure, and those presented as depressants do the
opposite.
In fact, the placebo
effect can be compared to the experience of watching a horror movie. Although
you know that what you're seeing isn't actually real, you most likely
experience some pretty real effects such as increase in the heart rate and
sweating.
Kaptchuk's work differed
from the traditional placebo effect, in that he told the patients that the pill
they were receiving was not real medicine. When the patients have this
knowledge, the term" open-label placebo" is used. The resulting
improvement' proved that in many cases, patients don't need to be tricked in
order for the desired effects of a placebo to take place. In fact, the fake
medication helped some patients so much that they requested additional pills
after the experiment was over.
Of course, the natural
question is: was this an extraordinary medical phenomenon, or just plain luck?
That's why Kaptchuk and his team are attempting to do a seven-week trial before
introducing the results to cancer survivors to treat severe tiredness caused by
the aftereffects of the disease.
