Herbal Nano-Formulations for Topical Delivery

The document is a comprehensive review of the development and application of herbal nano-formulations for topical drug delivery, focusing on various nano-carriers such as liposomes, ethosomes, lipid nanoparticles, phytosomes, nanoemulsions, transferosomes, ß-cyclodextrin complexes, niosomes, and polymeric nanomicelles. These formulations aim to enhance the delivery of herbal medicines through the skin by improving permeability, solubility, bioavailability, therapeutic activity, stability, tissue distribution, and sustained delivery. The review also discusses the importance of nanoparticle imaging techniques, surface charge, and formulation methods. It highlights specific studies, such as the formulation of a vaginal contraceptive with copper and curcumin, and a formulation containing 3-acetyl-11-keto-boswellic acid for enhanced skin permeability and anti-inflammatory activity. Safety and toxicity considerations are emphasized, with the conclusion that while nanoformulations show promise in effectively delivering herbal constituents through the skin barrier, the research is still in the early stages and requires further detailed studies. The document does not provide specific data on the number of people involved in any studies, as it is a general review rather than a report on a specific study.
