Herbal Nanoparticles: A New Perspective of Drug Delivery System-A Review

The nanoparticle is one of the most intensively studied areas in science, ranging from engineering to medical fields and has been a center of attraction that is explored to find new and promising dimensions for its use. These nanoparticles have obtained eminence because of their potential efficacy, shape, and size. In the field of nanoscience, the use of natural resources is an emerging topic of interest that has been taken into consideration due to the presence of a reservoir of a priceless wellspring of novel and new chemical entities that have a therapeutic effect. The system has found its space in the treatment of many diseases, including Diabetes, Neurological disorders, Cardiovascular Disorders, and even cancer. At present, cancer is one of the most common causes of death all over the world. Various drugs are used to treat numerous types of cancers, but at the same time, they are found to be harmful to the patient and produce several side effects. To meet the gap, herbal nanoparticles have been studied and are found to be nonhazardous and environmentally friendly. Herbal nanoparticles are synthesized to target various biological pathways that induce cancer and pieces of evidence have shown comparable efficacy like other drugs that have been used conventionally for cancer treatment. The review highlights the mechanism of action and prospects of the nanotechnological approach using phytochemicals for the treatment of cancer and will help to bridge the gap between herbal nanotechnology and current knowledge related to it.
