Nanotechnology Based Drug Delivery Systems of Herbal Medicine

Herbal medicine has been utilized extensively throughout ancient times. Advancements in the fields of phytochemistry and phytopharmacology has made it feasible to better understand the chemical composition and biological functions of certain medicinal plant products. The presence of active compounds is necessary for the efficacy of many species of medicinal plants. Most physiologically active components in extracts, such as tannins, terpenoids, and flavonoids, are highly soluble in aqueous solutions but exhibit poor absorption due to their large molecular size, low permeability, or inability to traverse lipid cell membranes. As a result, their bioavailability and efficacy are reduced, making certain extracts unsuitable for healthcare applications. There has been a lot of research into combining nanotechnology with herbal medicine because of the potential for nanostructured systems to enhance the benefits of plant extracts by reducing dosage requirements, minimizing side effects, and enhancing activity. Nanosystems may deliver a sufficient quantity of the active component to the targeted site of action during the course of the treatment. Conventional therapy fails to meet these requirements. The aim of this study is to review nanotechnology-based medicine delivery systems and herbal remedies.
