The property theory of traditional Chinese medicine(TCM)has been practiced for thousands of years,playing a pivotal role in the clinical application of TCM.While advancements in energy metabolism,chemical composition analysis,machine learning,ion current modeling,and supercritical fluid technol-ogy have provided valuable insight into how aspects of TCM property theory may be measured,these studies only capture specific aspects of TCM property theory in isolation,overlooking the holistic per-spective inherent in TCM.To systematically investigate the modern interpretation of the TCM property theory from multidimensional perspectives,we consulted the Chinese Pharmacopoeia(2020 edition)to compile a list of Chinese materia medica(CMM).Then,using the Latin names of each CMM and gut microbiota as keywords,we searched the PubMed database for relevant research on gut microbiota and CMM.The regulatory patterns of different herbs on gut microbiota were then summarized from the perspectives of the four natures,the five flavors and the meridian tropism.In terms of the four nat-ures,we found that warm-natured medicines promoted the colonization of specific beneficial bacteria,while cold-natured medicines boosted populations of some beneficial bacteria while suppressing patho-genic bacteria.Analysis of the five flavors revealed that sweet-flavored and bitter-flavored CMMs posi-tively influenced beneficial bacteria while inhibiting harmful bacteria.CMMs with different meridian tropism exhibited complex modulative patterns on gut microbiota,with Jueyin(Liver)and Taiyin(Lung)meridian CMMs generally exerting a stronger effect.The gut microbiota may be a biological indi-cator for characterizing the TCM property theory,which not only enhances our understanding of classic TCM theory but also contributes to its scientific advancement and application in healthcare.
