Placebo effect is defined as any improvement in discomfort or illness resulting from an intervention possessing no physical effect. Historically, the best research techniques always include a placebo control group and double-blinding \u2014 that is, neither the researchers nor the study patients know which group is which until the study is completed.

(Kind of like reading a list of possible adverse side effects from a medicine and thinking you are experiencing some of the symptoms.)<\/p>\n
Both the placebo and nocebo effects can occur as a \u201ctake-away\u201d from the benefit of a traditional therapy, or can stand alone from an inert therapy.<\/p>\n
