Secreted by plant cells, PDEVs facilitate intercellular communication by transporting metabolites. Unlike conventional liposomes and mammalian-derived EVs, PDEVs demonstrate excellent biocompatibility, stability, and the ability to cross biological barriers without inducing inflammatory or cytotoxic effects. Their capacity to encapsulate both hydrophilic and hydrophobic therapeutic agents highlight their versatility as targeted delivery platforms. Areas covered: This review summarizes PDEV biogenesis in comparison with mammalian-derived EVs and emphasizes characterization techniques and the role of lipid components in drug delivery efficacy. Drug loading strategies are critically examined with respect to their efficiency, advantages, and limitations. Advances in engineering, including surface modification and hybrid vesicle formation, are discussed to enhance targeting precision, circulation stability, and controlled drug release. Therapeutic potential and synergetic application in disease prevention and management are evaluated, alongside key considerations such as storage stability, current limitations, and opportunities for clinical translation. Expert opinion: PDEVs represents a promising platform for drug delivery and precision medicine. Although large-scale production, standardization and long-term stability remain challenges, recent innovations in loading strategies and engineering approaches demonstrate significant potential to overcome these barriers and accelerate clinical translation.falsedrug loadingengineered EVshybrid vesiclesPlant-derived extracellular vesiclestargeted drug deliveryreview10.1080/17425247.2025.25939812-s2.0-105023688374
