Wouldn’t it be great if eating some
sugar could alleviate pain, cure a cold, or even cancer? Recent studies suggest
this may be possible due to a placebo effect.
In Latin the word “placebo” means
“I will please.” In the medical field a placebo is known as a pharmacologically
inert substance which may produce therapeutic results because of the belief in
its efficacy (1). In research, a placebo is an inactive substance or procedure,
which on its own has no effect, used as a control. A placebo effect takes place
when the subject given the placebo demonstrates similar results as the
experimental substance or procedure (3).
