In a review of a recent research, international experts revealed that there is increasing evidence that fake treatments, or placebos, actually poses a biological effect in the body.

"At the core, placebo is about the mind-brain interaction so we know that there's lots of psychological components in placebo therapy, that's patients' beliefs, expectations, desire for improvement in their symptoms", said Australian pain researcher Damien Finniss, from Sydney's Royal North Shore Pain Management and Research Institute.

One of the key conclusions is that there is not just one placebo effect, but a combination of many.

Researchers revealed to have discovered that it is not what sugar pill or fake injection contains that makes patients experience a healthy state, however, the act itself of receiving treatment that switches on the brain to heal.

Pain expert Professor Michael Cousins cited that placebos will play a vital role in treating conditions such as chronic pain.

"We need to be more adept at using placebo as a part of the treatment we provide because placebo has very few adverse effects", he said.
