An Australian study stated that for patients apart from medicines, their doctor’s warmth was also important.
Sydney University's Damien Finniss who led a team of international experts after reviewing scientific papers on the impact of placebos, or dummy pills used in control tests, dating back to the 1700s, said, "Our research reveals that placebo effects can occur in routine medical practice across a wide range of medical conditions -- and these effects can be therapeutically powerful.”

The team found that mere medical practices like giving a drug was comforting for patients.

A finding concluded by one study that was confirmed by brain scans stated that patients whose medicine was replaced with a placebo later on still expressed relief in pain and other discomfort, which means that placebo, had a positive impact.

According to another study it was found that there were many patients who were benefited after they received a drug through injection from their doctor as compared to getting a medicine using a computerized pump.
