Herbal medicines have been used since antiquity to treat diseases and have
proven to be feasible alternatives. Numerous therapeutic plant species depend on a
supply of active ingredients to function effectively. Since they cannot cross the lipid
membrane, have an excessively large molecular size, or are least absorbed, most plant
extracts containing biologically active components such as tannins, flavonoids, and
terpenes have a lower absorption rate and are therefore less effective and bioavailable.
Additionally, because of these restrictions, certain extracts are not used. It has been
proposed that incorporating plant extract with nanoparticles enhances the solubility and
bioavailability of herbal medicines, allowing for increased uptake. Moreover, using
nanosystems, the active component may be delivered to the intended site of action over
the course of the treatment period at an appropriate concentration. Conventional
therapies do not satisfy them. This chapter discusses herbal medicine's medication
delivery method based on nanotechnology and its future prospects.
