Study: placebo can cause healing
American researchers from Boston examined migraine sufferers and showed how much expectations can influence the actual effect of drug therapy. The information provided by the treating therapist played a special role in this.
The researchers demonstrated that patients who received a placebo that they thought was an effective migraine remedy experienced the same pain relief as patients who took the correct medication, which the doctor had explained to them as inactive. It seems that the patient's confidence already has the same effect as the actual active ingredient.
If the migraine drug was described by doctors as highly effective, this doubled the pain-relieving effect. The authors summarize: The placebo effects are responsible for at least 50 percent of the effects. (pm)
