Question

Why do placebos work?​

Answer 1

Answer:

Placebos won't lower your cholesterol or shrink a tumor. Instead, placebos work on symptoms modulated by the brain, like the perception of pain. "Placebos may make you feel better, but they will not cure you," says Kaptchuk.

Answer 2

In drug testing and medical research, a placebo can be made to resemble an active medication or therapy so that it functions as a control; this is to prevent the recipient or others from knowing (with their consent) whether a treatment is active or inactive, as expectations about efficacy can influence results.
