Study: Even knowing that the body of a placebo was taken, the body could still have a positive effect.

According tomedia reports, the potential of placebos — “drugs” that do not contain active ingredients — is well known, although the exact cause of their effectiveness remains a mystery. In general, placebos are kept secret from the user, because the positive effects of this disappear if they know that they are eating sugar pills or some other false intervention. However, a new study suggests that this is not the case. The study found that placebos had a “powerful” effect even when the recipient sourced it.

Non-deceptive placebos refer to a placebo that recipients already know they are taking — a placebo that, according to a Michigan State University study, can still effectively relieve a person’s pain. The findings highlight the power of thought to bring change, although the limits of that power are uncertain.

In the study, the researchers divided the participants into two groups and showed each person a batch of “emotional images.” One group was given a non-deceptive placebo for physiological saline nasal sprays.

The placebo group knew they weren’t receiving real medication – they were told it was a placebo, and if they believed it would help them reduce negative emotions. The results were surprising.

Although the nasal spray was not known to contain any active ingredients, the group who took a non-deceptive placebo reported a decrease in negative mood. This is reflected in their eire activity — their eiactivity decreased after the use of the placebo. According to the study, this reduction was observed “within seconds”, suggesting that placebo is actually a potentially effective “therapeutic drug” with no side effects.

“Imagine if someone had taken a side-effect-free sugar pill twice a day and thus reduced stress after watching a convincing short film about the effects of a placebo,” said Darwin Guevarra, lead author of the study and a postdoctoral fellow at Michigan State University. These results raise the possibility. “
