葛根芩连汤作为一种传统中药复方，在治疗代谢性疾病方面展现出显著的疗效。随着中草药现代研究方法的进步，逐渐揭示了葛根芩连汤在代谢性疾病中的治疗作用及其分子机制，包括葛根素、黄芩苷、小檗碱等活性成分的抗炎作用。然而，中草药研究领域的新理论和新机制被不断发现，如影响肠道菌群、产生植物外囊泡、中药汤剂成分自组装等，使得对葛根芩连汤作用机制的理解亟待更新。本文旨在综述葛根芩连汤在代谢性疾病中的作用及机制，并结合最新的研究成果，重点分析其在肠道菌群、植物外囊泡和中药自组装领域的相关发现，探讨其潜在的治疗靶点和未来研究方向，为临床应用和基础研究提供指导。

      Gegen Qinlian decoction（GQD），as a traditional Chinese herbal formula，has demonstrated significant efficacy in treating metabolic diseases．With advancements in modern research methodologies for Chinese herbal medicine，the therapeutic effects and molecular mechanisms of GQD in metabolic diseases have been progressively uncovered，including the anti-inflammatory properties of its active components such as puerarin，baicalin，and berberine．However，emerging theories and mechanisms in the field of herbal research，such as modulation of gut microbiota，production of plant-derived extracellular vesicles，and self-assembly of components in herbal decoctions，continuously refine our understanding，highlighting the need to update insights into GQD’s mechanisms of action．This review aims to summarize the roles and mechanisms of GQD in metabolic diseases，integrating the latest research progress with a focus on findings related to gut microbiota，plant-derived extracellular vesicles，and self-assembly phenomena．It further seeks to explore potential therapeutic targets and future research directions，thereby providing guidance for clinical applications and fundamental studies．
