- Placebos, originating in the 1700s, are utilized in clinical trials to test new treatments without biasing results, although ethical concerns have reduced their use. They are still employed as controls to compare new drugs against existing treatments, emphasizing the continued relevance of the placebo effect in medical research.

The Power of Placebo: A Deceptive Relief
- In 1996, a study involving 56 volunteers tested a new painkiller called Trivaricaine. One index finger of each subject was treated with the new painkiller while the other remained untreated. Despite Trivaricaine being a fake concoction with no pain-easing properties, the subjects reported less pain in the treated finger, showcasing the power of the placebo effect.
- The term "placebo" originated in the 1700s when doctors realized the impact of fake drugs on improving symptoms. Placebos were designed to mimic real treatments, such as sugar pills or sham surgeries, and were later utilized in clinical trials as a standard tool to test new treatments without biasing results.
- While placebos have shown to provide relief for various ailments through the placebo effect, ethical concerns have led to a decrease in their use in clinical trials. However, they are still employed as controls to compare the effects of new drugs against existing treatments, showcasing the ongoing mystery and influence of the placebo effect on the human body.
