Ayurveda is the oldest system of Medicine in the world, its antiquity going back to the Vedas. It adapts a unique holistic approach to the entire science of life, health and cure. The areas of special consideration in Ayurveda are geriatrics, rejuvenation, nutrition, immunology, genetics and higher consciousness. The Ayurvedic texts describe a set of rejuvenative measures to impart biological sustenance to the bodily tissues. These remedies are called Rasayana which are claimed to act as micronutrients. Some of these Rasayanas are organ and tissue specific. Those specific to brain tissue are called Medhya Rasayana. Such Rasayanas retard brain aging and help in regeneration of neural tissues besides producing antistress, adaptogenic and memory enhancing effect. In addition to the long tradition of textual and experience-based evidence for their efficacy, certain recent studies conducted on these traditional remedies on scientific parameters have shown promising results which have been reviewed in this paper for providing lead for further studies. The popular Medhya Rasayanas are Ashwagandha (Withania somnifera Dunal), Brahmi (Bacopa monnieri Linn), Mandukaparni (Centella asiatica Linn) and Sankhapuspi (Convolvulus pluricaulis Chois).
