Double-blind procedure


In this procedure, a group of patients are given the real drug and another group with the placebo, or just sugar pills. The patients given the placebo usually get better from their illness by believing that they were given the real drug. This effect is called the placebo effect.
Double blind procedure: used in drug therapies, the patients and group of assistants are given placebo pills instead of the real ones so that patients shouldn't always rely on pills when they get sick. Make believe that positive results will happen because you think it's real.
