The Power of Placebo: "“Placebo” is Latin for “I shall please.”
Placebo trials are used to tell researchers whether a tested drug has any healing effect beyond that which occurs a certain percentage of time when people take an inert pill. A patient’s belief in a pill - a supposed medicine, but chemically innocuous - is thought to activate their body’s healing powers.
Do you believe the power of your mind can heal your body?
For years, scientists have looked at the placebo effect as just a figment of overactive patient imaginations. However, by now researchers have discovered that the placebo effect is not “all in patients’ heads” but rather, in their brains."
