The modern health and wellness landscape is rapidly transitioning from a disease-centric treatment approach to a preventive and holistic healthcare model. This transformation is largely influenced by the growing popularity of nutraceuticals, nutricosmetics, and the innovative application of nanotechnology in herbal medicine. Nutraceuticals combine nutritional and pharmaceutical benefits to support health promotion and disease prevention, while nutricosmetics focus on improving beauty and aesthetic health through internal nutritional supplementation that benefits skin, hair, and nails. Despite their significant therapeutic potential, many herbal compounds used in nutraceutical and nutricosmetic products suffer from limitations such as poor solubility, instability, and low bioavailability. These limitations reduce the effectiveness of plant-derived bioactive compounds when administered through conventional formulations. Nanotechnology has emerged as a promising solution to these challenges. Nano-herbal formulations incorporate herbal extracts into nanoscale delivery systems such as nanoparticles, liposomes, nanoemulsions, and nanocapsules. These advanced delivery systems enhance the stability, absorption, and targeted delivery of herbal bioactive compounds in the human body. Ayurveda, one of the oldest traditional medical systems, provides a vast repository of medicinal plants rich in therapeutic phytochemicals. Integrating Ayurvedic herbal knowledge with modern nanotechnology can significantly improve the efficacy of nutraceutical and nutricosmetic products.
