🔶 1. Introduction to Rasayana

In Ayurveda, Rasayana is a specialised branch of therapeutics designed to promote longevity (Deerghayush), memory (Smriti), intelligence (Medha), immunity (Vyadhikshamatva), and tissue regeneration. While general Rasayanas (Ajasrika) aim at maintaining the wellness of a healthy individual, Naimittika Rasayana is administered for a specific purpose (Nimitta) — particularly to support disease management and recovery.
