Placebo Effect

The placebo effect is an observable improvement in health or behavior no treated by a medication or administered treatment. Placebo is a substance that produces and effect similar to the active substance or to an antibiotic. Most common placebos may be , fake surgery and fake therapies .
The idea of the placebo effect originated with the scientist H.K Beecher. Beecher found out that about 35 percent of 1085, patients who took a pill containing no active ingredients experienced an improvement in their condition. 
In ten out of fifteen studies made by Beecher , 67 percent of the patients seemed to improve as a normal course of there illness and not attributable to placebo. In another study, a third of the patient’s symptoms improved with a placebo for treating there colds.  Another of Beecher’s studies was that when he took drug treatment to their patients and change it with placebo , instead of worsen there symptoms it improved them , because the actual drugs caused side effects that the placebo didn’t.
There are a lot of factors that can affect many treatments and the evaluation of those treatments. That make it very difficult to be sure just what it is about an involvement that produces improvement or superficial improvement. An example of these factors is that Beecher only showed the percentage of the patients that improve their conditions not of the percentage that didn’t improved with placebo effect.
Finally I think that the placebos are fake substances that make our minds thinks were improving but we are not , it might be good in some cases , and bad in others. It can be bad , because not always imaginary treatment can treat like a real treatment does , that’s because not all injuries or viruses are easily treated , and more if treated only mentally . “Vitamins and herbs are real. Placebos are only imaginary.”
