Limitations include data gaps in multi-omics validation and herbal standardization, with future directions leveraging AI-driven predictions for personalized pharmacotherapy.</p>","PeriodicalId":7259,"journal":{"name":"ADMET and DMPK","volume":"14 ","pages":"3281"},"PeriodicalIF":5.1,"publicationDate":"2026-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13499659/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148786888","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
