Nano-Formulations Of Herbal Medicines: "Recent, Trends, Challenges And Future Prospective".

Herbal medicines have been used for centuries for the prevention and treatment of various diseases because of their natural origin and therapeutic properties. However, many herbal compounds have limitations such as poor solubility, low bioavailability, rapid degradation, and poor absorption in the body. Nanoformulation is an advanced approach that uses nanotechnology to improve the delivery and effectiveness of herbal medicines. Nanoformulations involve reducing herbal active compounds to nanoscale and incorporating them into systems such as nanoparticles, nanoemulsions, liposomes, nanocapsules, and phytosomes. These systems can improve the solubility, stability, absorption, and controlled release of herbal compounds. Recent trends in herbal nanoformulations include the development of targeted drug delivery systems, combination of herbal compounds with nanocarriers, green synthesis of nanoparticles, and use of smart and stimuli-responsive nanocarriers. These approaches may improve therapeutic activity while reducing unwanted effects. However, challenges such as toxicity, stability, large-scale production, high cost, limited clinical studies, and lack of standardized regulatory guidelines remain. Future research should focus on developing safe, stable, cost-effective, and reproducible nanoformulations. More clinical studies are also required to establish their safety and therapeutic effectiveness. Overall, herbal nanoformulations represent a promising approach for improving the delivery and potential therapeutic benefits of herbal medicines.
