No, double blind studies are done so that what we are testing the effectiveness or lack thereof of the drug itself, not other factors, such as psychological factors. It only tries to establish whether or not a drug has a statistically significant effect or not.

The double blind placebo trial was only invented in the 60's and medicine has been used way before then
