Herbal remedies and natural products are being used for an ancient time to cure diseases. Unlike the existing allopathic system, herbal remedies have hundreds and thousands of components that all work together against diseases. Natural products produced by organisms such as fungi, bacteria, animals and plants act as biologically active agents. For the most part, conventional pharmaceuticals or pharmacognostics products on the market rely on natural products and their derivatives with herbal products playing a key role. Throughout the world, research on these herbal remedies has been carried out in the different fields, for example, pharmaceutical chemistry, pharmacognosy, pharmacology and clinical therapeutics. Incorporation of these herbal extracts into new formulation systems in order to have added advantages and to exceed their bulk dose and less absorption which is the main problem they face, attracting the attention of large pharmaceutical corporations. 'Nanotechnology' is the emerging new technology in drug discovery and has the property of self-directed in the sense that without the binding of a specific ligand, these can be used to direct, because of their distinctively small size, to Pathologically infected areas. Some of these formulations are already on the market and are expected to arrive many more in 2020 after their success in ongoing clinical trials. In this review, this new approach is raising the interest of the number of scientists to improve and accelerate the discovery and joint development of new nano delivery systems for herbal extracts.
