Answer: something you can take to place of an actual medication...\n\nexample: the 4th week you take on your birth control pills is a placebo so that you stay in the routine of taking the pills but it is actually jsut a sugar pill...\n\n\nand often in research studies someindividuals are given a real medication and others are given a placebo, this way the researchers can determine if the medication makes a difference on the persons health, but the individual doesn't know if they are actually on  the medication or taking the placebo..
