Abstract

Among the eight branches of Ayurveda, Rasayana chikitsa is an important branch. The term Rasayana means the proper ayana (path), the footstep of nutritional requirements, which is the basis for a younger and healthy life. Ayurvedic classics explain Rasayana's effect as attaining longevity, memory, intellect, freedom from diseases, youth, excellence of lustre, complexion, voice, etc. Among the various Rasayana yogas mentioned in Ayurveda, Narasimha Rasayana (NR) is a unique formulation mentioned in Ashtanga Hridaya containing ingredients like Khadira, Chitraka, Shimshapa, Vijayasara, Haritaki, Vidanga, Vibhitaki, Bhallataka, Lohashakala, go-dugdha, Bhringaraja, Shatavari which are processed in navaneeta. The indications of the formulation include a strong, swift and steady physique with shining black hair, good complexion, good intellect, digestive power, etc. In the present review, an attempt has been made to analyse the formulation, highlighting the properties of individual ingredients from a classical and modern perspective. The study revealed that the ingredients of Narasimha Rasayana possess antioxidant, immunomodulatory, anti-mutagenic and hemopoietic effects, among other qualities, which point towards a possible rejuvenating impact on the human body.
