ABSTRACT
The agents which cure body and mental diseases, delay old age, increase mental power, generating power, vital energy, eyesight, impart intelligence, memory, aid proper digestion and clear complexion are Rasayana (Shastri, 1979). These nourish the whole body by strengthening the primordial tissue Rasa, the essence of all food we take, and which the body can assimilate. If this essence is well distributed in all systems, the body remains healthy. By their physico-chemical action Rasayana purify and promote dhatus (tissue). They augment the body’s disease resistance capacity, as well as the ability for restorative reaction and counteract all the deleterious effects including that of ageing.
