When scientists are carrying out clinical trials for a new medicine they need to have a control group to compare their results. Just in case the act of taking a tablet or pill, for example, has an affect on a patient they use a placebo in the control group of patients. The placebo has no medicinal effect and the control group takes this and can therefore be compared to a test group which are actually given the medicine.
