Effective disease prevention and treatment depend on the delivery of phytochemicals, and innovative drug delivery methods based on nanotechnology have been created for the delivery of herbal medicines. The potential of lipid-based carrier systems, such as vesicular systems, lipid particulates, and nanoemulsions, to boost the stability and bioactivity of phytochemical substances has drawn attention. Drug solubility, effectiveness, and bioavailability can all be enhanced by liposomes because of their excellent biocompatibility and biodegradability. Nevertheless, liposomes exhibit stability problems and self-leakage when exposed to specific medications. A common stabilizer used to preserve liposome stability is DSPE–MPEG 2000 (DP). Micelles, polymersomes, and dendrimers are examples of structures that can be formed using polymers as phytochemical transporters. Poly(glycolide-co-lactide) (PGLA), alginate, albumin, chitosan, starch, and polylactic acid are a few examples of synthetic and natural polymers that are employed.
