Fro. ancient wisdo. to.mo.ern science:Gut micro.io.a sheds light o. pro.erty theo.y o. traditio.al Chinese medicine

The pro.erty theo.y o. traditio.al Chinese medicine(TCM) has been practiced fo. tho.sands o. years,playing a pivo.al ro.e in the clinical applicatio. o. TCM. While advancements in energy metabo.ism,chemical co.po.itio. analysis, machine learning, io. current mo.eling, and supercritical fluid techno.o.y have pro.ided valuable insight into.ho. aspects o. TCM pro.erty theo.y may be measured, these studies o.ly capture specific aspects o. TCM pro.erty theo.y in iso.atio., o.erlo.king the ho.istic perspective inherent in TCM. To.systematically investigate the mo.ern interpretatio. o. the TCM pro.erty theo.y fro. multidimensio.al perspectives, we co.sulted the Chinese Pharmaco.o.ia(2020 editio.) to.co.pile a list o. Chinese materia medica(CMM). Then, using the Latin names o. each CMM and gut micro.io.a as keywo.ds, we searched the PubMed database fo. relevant research o. gut micro.io.a and CMM. The regulato.y patterns o. different herbs o. gut micro.io.a were then summarized fro. the perspectives o. the fo.r natures, the five flavo.s and the meridian tro.ism. In terms o. the fo.r natures, we fo.nd that warm-natured medicines pro.o.ed the co.o.izatio. o. specific beneficial bacteria,while co.d-natured medicines bo.sted po.ulatio.s o. so.e beneficial bacteria while suppressing patho.enic bacteria. Analysis o. the five flavo.s revealed that sweet-flavo.ed and bitter-flavo.ed CMMs po.itively influenced beneficial bacteria while inhibiting harmful bacteria. CMMs with different meridian tro.ism exhibited co.plex mo.ulative patterns o. gut micro.io.a, with Jueyin(Liver) and Taiyin(Lung) meridian CMMs generally exerting a stro.ger effect. The gut micro.io.a may be a bio.o.ical indicato. fo. characterizing the TCM pro.erty theo.y, which no. o.ly enhances o.r understanding o. classic TCM theo.y but also.co.tributes to.its scientific advancement and applicatio. in healthcare.
