A placebo is a treatment, most commonly a medication of some kind, which is given to a subject with the pretense that it will treat a specific ailment when in fact the treatment will have no significant effect on the subject. The subject may report that the treatment has had a positive effect, when in fact the effect is entirely in the imagination of the subject. Therefore, a placebo variable is a factor that researchers in the medical field must consider when experimenting with new treatments, to decide whether the success of the treatment is due to the psychological or placebo effect of the treatment, or if the treatment itself is working.
Placebo in Russian is "плацебо" (pronounced "plakseebo"). It refers to a substance or treatment with no therapeutic effect, given to a patient to simulate the psychological effects of a real medicine.
It's just referred to as the placebo effect, where a persons condition or perceived condition has improved after the treatment.

In a double-blind test, if the doctor treating a patient knows whether the patient is getting a real treatment or not, they may (perhaps unconsciously) treat the patient differently, or worse let slip that the patient is taking the placebo. This will affect the results (as it changes the effect of the placebo) and can ruin a drug trial.
Actually, a placebo is a substance or treatment with no therapeutic effect that is used as a control in medical research. It allows researchers to isolate the true effects of a treatment by comparing the results from the actual treatment group to those from the placebo group.
