To answer this question, we reviewed the original concept of acupoints explained in Oriental medicine, from which acupuncture treatment originated, and examined scientific research on acupuncture and acupoints. We then proposed a perspective on the identity of acupoints and speculated about a possible reason for their elusive nature: qi, which congregates at and flows in and out of acupoints, might be bioelectricity, making these points inherently difficult to measure anatomically or histologically. Consequently, acupoints are suggested to be spaces where bioelectricity congregates, thus inevitably exhibiting electrical characteristics.</p>","PeriodicalId":46854,"journal":{"name":"Journal of Acupuncture and Meridian Studies","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2024-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142113262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
