When seeing the doctor, you feel better to know you will get some medicine. But the doctor knows that medicine is not always needed. Sometimes all a sick person needs is some reassurance that all will be well. In such cases the doctor may prescribe a placebo.

A placebo is a sugar pill, a harmless shot, or an empty capsule. The patient thinks it is medicine and begins to get better. How does this happen?

The study of the placebo opens up new knowledge about the way the human body can heal itself. It is as if there was a doctor in each of us. The doctor will heal the body for us if we let it. But it is not yet known just how the placebo works to heal the body. Some people say it works because the human mind fools itself. These people say that if the mind is fooled into thinking it got medicine, then it will act as if it did, and the body will feel better.

Placebos don’t always work. The success of this treatment seems to rest a lot with the relationship between the patient and the doctor. If the patient has lots of trust in the doctor and if the doctor really wants to help the patient, then the placebo is more likely to work. So in a way, the doctor is the most powerful placebo of all.

A placebo can also have bad effects. If patients expert a bad reaction to medicine, then they’ll also show a bad reaction to the placebo. Some doctors still think that if the placebo can have bad effects it should never be used. They think there is still not enough known about it.

The strange power of the placebo does seem to suggest that the human mind is stronger than we think it is. There are people who say you can heal your body by using your mind. And the interesting thing is that even people who swear this is not possible have been healed by a placebo.
