The Editor has retracted this article [1] due to concerns about the scientific validity and reproducibility of the findings. Post-publication peer review has concluded that there is no information on or plausible molecular mechanism which explains what the External Qi of Yan Xin Qigong is, how it is produced, and how it could be reproduced by others.

All authors disagree with this retraction.
