Placebo effect refers to a deceptive treatment with inactive substances that ameliorates patient’s condition through psychological effect. For example, patients who believe that the doctor will be able to treat them well will be able to recover much rapidly than patients who put only minimal belief that the doctor will be able to heal them. This phenomenon occurs because placebo has a high degree of therapeutic effectiveness in treating subjective responses through emotions and expectations of patients. An advantage of the placebo effect is that placebos tend to result in less side effects within the boundaries of the therapeutic relationship than drugs “the value of treatment like those - which have none of the side effects of drugs" (The Power of Nothing, Specter). This is possible because the outcome of the result relies on the patient’s belief of effectiveness of placebo. A disadvantage of the placebo effect is that the result/process of its outcome and how it is processed is very difficult to prove. Thus, it hasn't been proven yet. Unless researchers and scientists succeed to inspect the underlying process of how placebo works, the idea of doctors giving their patients a “fake” medication under false pretenses that involves no method of biology, will be indeed difficult to become accepted. Placebo demonstrates a strong relationship between person’s perception of the pill and the therapeutic outcome; the stronger the feeling, the more likely of positive effects. The benefiting outcome of placebo results from a substance called endorphin that is secreted in the brain, similar to opiates like morphine and heroin. For example, let’s take an account of this study that illustrates the relationship of mindset and the positive therapeutic outcome. During World War II, Lieutenant Colonel Henry Beecher attempted to ease soldiers’ pain from injuries. After the soldiers were given placebo, they were asked if they wanted mo
