A Comprehensive Review of Nanotechnology Based Nanoemulsion Delivery Systems for Targeted Drug Delivery and Enhanced Therapeutic Efficacy

Herbal medicine has been a cornerstone of traditional healthcare for centuries, offering a wide array of bioactive compounds derived from plants. However, its efficacy is often limited by poor bioavailability, instability, and non-targeted delivery. Recent advancements in nanotechnology have provided innovative solutions to these challenges through developing nanoemulsion delivery systems. These systems enhance the solubility and stability of herbal extracts, ensuring targeted delivery to specific tissues or cells. Nanocarriers such as liposomes, solid lipid nanoparticles, and polymeric nanoparticles can encapsulate bioactive compounds, protecting them from degradation and facilitating controlled release. This approach not only improves therapeutic outcomes but also reduces side effects by minimizing exposure to non-targeted areas. Furthermore, nanotechnology allows for personalized medicine by tailoring nanocarriers to individual patient needs, enhancing treatment efficacy and compliance. The integration of nanotechnology with herbal medicine holds significant potential for revolutionizing healthcare by providing more effective and targeted treatments for various diseases, including cancer, neurological disorders, and cardiovascular diseases.
