Today we present 20 new placebo and nocebo research papers, book chapters, comments and abstracts identified during September 2023. As usual, they are based on new PUBMED publication using the search terms „placebo“ and „nocebo“ and are hand-selected from more than 724 new publications during the preceding month. Previously published monthly updates can be found in our archive. Todays selection as well as all previously identified papers will also go into our placebo research library that currently contains nearly 5,000 relevant papers.
