title: Publications on experimental physical methods to investigate ultra high dilutions--an assessment on quality.
abstract: BACKGROUND
  Our first evaluation of fundamental research into the physics and physiology of Ultra High Dilution (UHD) was conducted in 1994. Since then, in 2003, Becker-Witt et al. conducted a more systematic evaluation of the literature and established the Score for Assessment of Physical Experiments on Homeopathy (SAPEH). While this evaluation focused on experimental methodologies, Stock-Schröer et al., in 2009, formulated a detailed guideline for authors on Reporting Experiments in Homeopathic Basic research (REHBaR) to promote a high standard in research as well as in its communication in scientific literature.
  
  
  METHODS
  In this paper, we evaluate publications on basic research into the physics of UHD since the decade following the presentation of the SAPEH score (2004-2014), and present the state of progress in this field.
  
  
  RESULTS
  Fundamental research into the physics of UHD has been reported at a steady rate over the past 60 years. Reported research of high quality as per SAPEH scoring appears to be still the exception rather than standard.
  
  
  CONCLUSIONS
  Considering the importance of a fundamental understanding of what makes a UHD preparation, results of this study suggest that it may be beneficial to this field of fundamental research if grant challenges are approached in strategic way similar to other grant challenges in science.
