The main ingredients of herbal medicines, which have been utilized for medical purposes since ancient times, are phytochemicals. Because they are more widely available and have a safe toxicological profile, plants are utilized to treat a variety of illnesses. Physicochemical degradation of phytoconstituents results from these plants’ poorer solubility and bioavailability research, among other drawbacks. Novel medication design based on nanotechnology aims to create drug carriers that increase the phytoactivity, solubility, and bioavailability of herbal remedies.
