Phytomedicines have been serving as a crucial source of drugs sinceancient times, their usage has been increased due to their therapeutic activity and less side effects rather than the other medicines. Both developing and developed countries are focusing on the popularity of herbal drugs mainly due to their natural origin and low side effects. Fast-growing nanotechnologies have provided strong support for developing innovative novel herbal drugs. Nutraceuticals are foods and food constituents that provide health benefits beyond basic nutrition, but many nutraceuticals show poor bioavailability. Applications of nanotechnology have granted to overcome the challenges and technical barriers related to the solubility, bioavailability, stability and delivery of bioactives from foods.
The rapid growth of nutraceutical nanotechnology carries great promise to provide new and effective functional foods as a tool for preventing and possible even bringing a cure to some non-communicable diseases. Numerous studies are already reported in different types of preparative methods of nanomaterials in the field of nanotechnology for herbal drug delivery and nutraceuticals. The current review focuses on the introduction of nanotechnology in herbal drugs and nutraceuticals for nanomedicine and functional foods. It is also highlights important and rapid developments in biomedical and food technology.
