The book begins with an overview of recent facts and diverse perspectives on the use of nutraceuticals in medicine and proceeds to discuss recent techniques in isolation of nutraceuticals from plants and in solubility enhancement. It looks at innovations and advances in nanoparticles-based nutraceutical delivery, such as in solid lipid nanoparticles (SLNs), fabrication methods of therapeutic nanoparticles, and polymeric nanoparticles-based nutraceutical delivery system. It also discusses vesicular delivery systems and biphasic systems for nutraceutical applications. The book also looks at the challenges in oral delivery and the latest taste-masking techniques.
