Detailed explanation-1: -A placebo (/pləˈsiːboʊ/ plə-SEE-boh) is a substance or treatment which is designed to have no therapeutic value.
Detailed explanation-2: -What is the placebo effect? The placebo effect is when a person’s physical or mental health appears to improve after taking a placebo or ‘dummy’ treatment. Placebo is Latin for ‘I will please’ and refers to a treatment that appears real, but is designed to have no therapeutic benefit.
Detailed explanation-3: -A placebo is an inactive substance that looks like the drug or treatment being tested. Comparing results from the two groups suggests whether changes in the test group result from the treatment or occur by chance.
Detailed explanation-4: -Placebo effect examples After participants take the pill, their blood pressure and pulse rate increases, and their reaction speeds are improved. However, when the same people are given the same pill and told it will help them relax and sleep, they report experiencing relaxation instead.
Detailed explanation-5: -In order to make sure a new drug or vaccine is effective, studies often use a placebo or control group. Placebos are “sugar pills” or “dummy drugs” with no active ingredients and are made to look like the real medicine. A control is a standard treatment (that may be currently used) for the illness.
