Green Nanotechnology is the study of how nanotechnology can benefit the environment, such as by using less energy during the manufacturing process, the ability to recycle products after use, and using eco-friendly materials. Nanotechnology covers the diverse area of matters at dimensions between approximately 1 to 100 nanometers. Herbal medicines have been widely used all over the world since ancient times and have been recognized by physicians and patients for their better therapeutic value as they have fewer adverse effects as compared with modern medicines. Phytotherapeutics need a scientific approach to deliver the components in a sustained manner to increase patient compliance and avoid repeated administration. This can be achieved by designing novel drug delivery systems (NDDS) for herbal constituents. The integration of the nanoscience as a NDDS in traditional system of medicine enriches the potential of herbal drugs for treating chronic diseases. Ayurveda is thousands of years old holistic system of Indian medicine. Various herbs, metals and non-metal preparations are used as medicine in Ayurveda. This review paper opens door to a completely new dimension in herbal medicine and ayurveda using green nanotechnology.
