PLACEBO effect.

We have always talked about the mind is the most powerful thing that exists and many scientists say that the brain controls our conviction, given the circumstances of our claims, but it can happen that we cure a certain disease just by thinking and wanting to cure ourselves, is it all this possible? We are like the old saying "see to believe", many things that exist in our world and we simply do not know it or we do not put it into practice, I will make a brief summary toto see what it is about and how this called PLACEBO Effect works.

It has happened to us that our head hurts a lot, and we ask for a pill and without caring, without asking what are the chemical components of the pill we take it and sometimes we create a certain doubt and ask what is this pill? and they only tell us "drink the pill and remove the pain", and just wait a while and "puff" we have no pain, it's amazing how our mind works, our positivism just having the desire to heal can occur.

PLACEBO effect

It is the positive and beneficial effect that happens when a person takes medication or substance (PLACEBO) waiting for results that could help, but the elements of the medicine has no curative effect because of the problem being treated, the substance or the treatment is not it contains no quality to produce an improvement in the symptomatology, but it provokes a feeling of belief that it is going to improve, but in a way one way or another with the treatment it receives causes the improvement by itself.

This effect can also be considered in psychological treatments, surgeries or other interventions. The PLACEBOS more common: sugar pills, surgeries and infusions, in some cases it can be any medication or 'false' treatment. It is all that seems to be a real medical treatment but in reality it is not.

The color of the pills also matters in this effect, we human beings let ourselves be carried away by the shapes and colors that happens because it affects a level of the subconscious, the researchers discovered that the pills are more effective than the pills, there are yellow placebos for treat depression red so that the patient is more alert and awake, greens for anxiety and whites to relieve stomach problems, gastritis, ulcers etc.

Is everything in the head?

There are many theories, but one of them is that the PLACEBO Effect works to the illusion of expectation and hope. The person already knows what is the result of taking the medicine, unconscious can modify its reaction could be modified, and produces that same result, simple informs the body of the result of the intake as a consequence.

Another theory called Classical Conditioning by Ivan Pavlov, says that the stimulus would be medicine and the answer is the relief of symptoms.

The investigation of the PLACEBOS

In the major investigations, placebos are used in clinical trials and determine the effectiveness and potential effectiveness of a drug and if it actually works.

In the trial, one that receives the experimental drug and one that receives the PLACEBO is separated into two groups (It can be an ineffective substance or the active drug, it depends on the test).

The trials are usually double-blind, which means that neither the people nor the researchers who are doing the process know which of the groups receives the experimental drug, to avoid any potential bias. If any of the researchers knows that they are administering it, they could convey doubts about its effectiveness to the subject.

Pain studies using brain images, it has been shown that the administration of a placebo to people who thought they were receiving analgesics, activated the endogenous opioid system of the brain, endogenous opioids such as endorphins and enkephalins are natural pain-relieving chemicals produced in the body.

The response to placebo in post-operative patients could be blocked by the opioid antagonist naloxone, central nervous system neurotransmitter, it has been shown that the brain is activated after administering placebo in patients with Parkinson's.

Conclusion

There are many things in life that we do not know, it is impressive the capacity and power that we have when we feel sick wanting to improve and put hope in all possible medicines.

It is a sample of how our brain works and what it is capable of receiving this type of effects, it is a fairly extensive subject with many studies that have proven its acceptability and success, and on the other hand professionals say that it is charlatanism in this effect, we must bear in mind that the effect PLACEBO can be found in treatments of proven effectiveness, an example of this is the recovery or improvement when taking a medication, an antidepressant for example. The treatment can be effective and proven, usually these drugs take weeks to be effective, an improvement of the patient earlier may be due to the placebo effect, this phenomenon as well as the healing produced by the mechanism of efficacy of a drug or psychotherapy can they can be hidden
