A placebo can also have bad effects. If patients expect a bad reaction to medicine, then they will also show a bad reaction to the placebo. This would seem to show that a lot of how you react to medicine is in your mind rather than in your body. 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. And yet, the use of the placebo has been well known for hundreds of years in other countries. Tribal doctors in some African countries have known for a long time that patients will get better if they think they are going to. Many of the "treatments" they use do not seem able to make a sick person better, and yet such treatments work. 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.
