Increasing scientific research on traditional Chinese medicine and acupuncture provides science-based explanations like deqi.
However, most of the research focuses on diseases instead of following TCM and acupuncture theories about pattern identification.
Timing is closely connected with therapeutic effects and surely plays a key role in the clinical efficacy that is often ignored. On the
other hand, whether or not timing-related efficacy can be influenced with age, gender, and the processing of materia medica in
Chinese herbs and acupuncture needs more attention and research.
