A Review on Nano Drug Delivery Systems of Herbal Medicine

Herbal medicines are widely used around the world since history. The advancement of phytochemical and phytopharmacological sciences has enabled elucidation of many medicative plant products' composition and biological activities. The effectiveness of the many species of medicative plants depends on the provision of active compounds. Most of the biologically active constituents of extracts, like flavonoids, tannins, and terpenoids, are extremely soluble in water; however, have low absorption, as a result of their unable to cross the lipoid membranes of the cells, have enormous molecular size, or poorly absorbed, leading to loss of bioavailability and effectiveness. Some extracts are not used clinically due to these obstacles. It has been wide planned to mix seasoner medication with herbal, resulting from nanostructured systems that may be ready to enhance plant extracts' action, reduce the specified dose and facet effects, and raise activity. Nanosystems will deliver the active constituent at a spare concentration throughout the whole treatment amount, directional it to the required web site of action. Typical treatments do not meet these necessities. This study aimed to review nanotechnology-based drug delivery systems and herbal medicines.
