Ayurveda has two main aims - one is to maintain the health of a healthy individual and the second is to treat a diseased person. Rasayana Chikitsa has a significant role in meeting Ayurveda's first goal. Rasayana Chikitsa is also a part of Ashtanga Ayurveda which presents its importance. Rasayana is any herb, food, or activity that confers youthfulness and cures diseases. If taken properly, the Rasayana prevents early aging and keeps you young and active both physically and mentally. Rasayana primarily refers to nourishment on all scales, from the macro to the micro-cellular level. All Rasayanas are nutrition promotores in general but there are certain target-specific Rasayana Medhya Rasayana for the brain, Hridya Rasayana for the heart, Chakshusya Rasayana for the eye, etc. It accelerates the formation of new Dhatus and retards aging. This way, it comprehends our body's vital energy and boosts immunity. A good intellectual power acts as a catalyst in all aspects of life. Ayurveda provides a list of herbs known for nootropic activity and their multi-dimensional utility in various conditions. Yashtimadhu, Guduchi, Shankhapushpi, and Mandookparni are the four Medhya Rasayana that Acharya Charaka briefly explained. It is said that Shankhapushpi is the best among all Medhya Rasayana Dravya. These drugs enhance one's capacity for acquiring knowledge (Dhi), retention (Dhriti), and memory (Smriti). Medhya Rasayana medications are used to promote health and prevent and treat mental illnesses in people of all ages. Recently there has been a tremendous urge to explore medicinal plants globally for improving cognitive function owing to their less adverse effects. Throughout the Nighantu period, more cognitive enhancers were occasionally introduced to classical literature under the label Smritikara Dravya and in folk practice.
