According to a prevalent medical view presented in the passage, ----.
"Placebo" is a Latin word which means "I will
please", in medicine it has come to mean a
treatment - a sugar pill or saline injection - that,
in itself, has no physical effect. In spite of this,
placebos have often been found to relieve
physical symptoms such as pain, swelling,
inflammation, or even depression. Apparently,
in such cases, it is the act of treatment rather
than the treatment itself that is effective. Why
there should be such a thing as the placebo
effect remains problematic. Many doctors have
suggested that it was selected by evolution as
a means of managing the resources of the
immune system. Given that placebos seem to
work, in part, by suppressing the immune
response, they may be a way of conserving
the body's energy at critical moments. Patients
may even get depressed to stop them from
being too active and so slowing recovery. It is
a high price to pay, but then evolution is not a
merciful master.
