What is the placebo effect?
During almost all clinical drug studies, a certain percentage of volunteers will receive the same looking but chemically neutral pill or inject called placebo. A group of volunteers who receive this placebo can be used as a control group, which means that their reactions will be compared with those volunteers who actually received a real medicine. There is also a possibility that volunteers or testers would have no idea who volunteers took placebo and received a real drug. This scenario is known that there is a controversial phenomenon known as placebo effect . Although the patient or volunteer gets a completely harmless sugar pill or sterilized water injection, the possibility to accept the actual drug creates a placebo effect. According to some researches, a certain percentage of those patients who unknowingly receive placebo, report some signs of improvement, especially in the area of pain treatment and overall energy level.
Most experts consider placebo the effect of a psychosomatic nature because there are no active compounds in placebos. It has been speculated that scientists themselves help to create a placebo by telling volunteers that they may or may not receive an active form of drug. If a motivated volunteer decides to believe that he has actually received a real drug, he can become too sensitive to any change in his condition. Interestingly, many who have experienced a placebo effect report only minor to medium changes in their conditions, not complete medicines or remission.
The effect of placebo could also be related to the release of the natural pain of the body killer body called endorphins, as well as other chemicals designed to combat depression or increase energy levels. While the placebo itself may not have any recognizable effect on the chemistry of the body of the volunteer, some patients may experience a sense of peace or peace of mind after receiving thiso What could be a beneficial treatment. The effect of placebo can be similar to psychological benefits that many people experience after a doctor's test. The obvious improvement in the symptoms caused by the effect of placebo could be the result that the volunteer receives personal attention and assurance of the expert.
However, scientists are not generally recognized. Almost all reported advantages are non -invantifiable diversity, such as reducing pain or improved mental focus, which means that they cannot be easily verified by standard medical testing. A volunteer who received a placebo, specifically how effective it seems to be a test remedy. The effect of placebo, if it is indeed an effect, may be a case of pious thinking by a volunteer who hoped that the real drug was demonstrated safe and effective.
