Participants self-reported herbal and pharmaceutical use, and a targeted literature review was undertaken to assess potential pharmacokinetic and pharmacodynamic interactions between commonly reported herbal products and prescribed medications.</p><p><strong>Results: </strong>Participants reported concurrent use of a wide variety of herbal products (e.g., garlic, ginger, okra, lemon, mango, moringa) with prescription medicines (e.g., metformin, insulin, glibenclamide, hydrochlorothiazide, enalapril, amlodipine). While clinical outcomes were not independently verified, literature review findings, in some cases, indicated meaningful potential for HDIs.</p><p><strong>Discussion and conclusion: </strong>This study provides foundational data on herbal-pharmaceutical co-use in Malawi and highlights the need for expanded research, improved documentation of herbal use in healthcare settings, and improved education for patients and providers. Integrating awareness of herbal product use into clinical care is essential, and the methodology and findings may inform future hypothesis-driven studies across Africa and other regions where traditional and modern medicine use overlaps.</p>","PeriodicalId":19942,"journal":{"name":"Pharmaceutical Biology","volume":"63 1","pages":"877-895"},"PeriodicalIF":6.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12632214/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145557416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
