Considering this, how does the placebo effect work in the brain?

Also question is, does the placebo effect work if you know about it?
Traditionally it was thought that sugar pills were only effective when their clinical inefficacy was hidden from the patient. However, an intriguing new trial has shown that people still get the benefits even if they know it is placebo, provided they are told they may experience an effect.
Is the placebo effect getting stronger?
A sugar pill—if not revealed to the patient—can sometimes heal. Over the past two decades, a lot of clinical trials are showing that the sugar pill's effects are getting stronger.
