Herbal therapeutics have long been valued for their diverse pharmacological properties, biocompatibility, and reduced side effects. However, the clinical translation of herbal bioactives remains challenging due to poor aqueous solubility, limited membrane permeability, rapid metabolism, and degradation in physiological environments. Recent advances in nanotechnology have revolutionized the formulation and delivery of herbal compounds by enabling improved solubility, targeted transport, and controlled release of active constituents. Nanotechnology-enabled systems such as liposomes, polymeric nanoparticles, solid lipid nanoparticles (SLNs), nanoemulsions, dendrimers, and nanomicelles have demonstrated significant potential in enhancing the bioavailability and therapeutic performance of herbal medicines. These nanocarriers not only protect unstable phytoconstituents from degradation but also facilitate site-specific delivery, reducing systemic toxicity and improving pharmacokinetic and pharmacodynamic profiles. Current research emphasizes the integration of green synthesis approaches, biocompatible polymers, and surface-engineered nanostructures for efficient and sustainable herbal drug delivery. Despite promising advancements, challenges remain regarding large-scale production, reproducibility, toxicity evaluation, and regulatory compliance. Future efforts should focus on standardized characterization methods, in vivo pharmacological validation, and translational studies to ensure clinical applicability. Overall, nanotechnology-enabled delivery systems represent a transformative platform for the modernization of herbal therapeutics, bridging traditional knowledge with contemporary pharmaceutical innovation.
