Rasayana is an Ayurvedic rejuvenation therapy which helps in maintenance & promotion of health. It is an unique branch of Ashtanga Ayurveda, and its importance in therapy is reflected in its name. It is human nature to desire long life, and this desire is shared by almost all peoples on the planet. As a result, if longevity is sought, a system of rejuvenation for those who want to stay young must exist (1-2).
Rasayana Chikitsa is reported by several Acharyas in Ayurvedic writings to improve immunity (Vyadhikshamatva bala) and prevent old age. Rasayana Chikitsa is also used for disease prevention, treatment, and promotion. As we get older, we start to lose some of our abilities. At different ages, different rejuvenating medicines are required to replenish these losses. Rasayana also entails escalation of the mind's Satva Guna, which can only be accomplished by combining it with Achara Rasayana (3-4).
It is equally vital in both the treatment and maintenance of health. Different drugs, depending on the condition, are helpful in rectifying Dhatu Vaishamya and achieving Dhatu Samya. (5).
Rasayana has a critical role in problems associated with sedentary lifestyles, work-related stress, poor eating habits, and non-communicable diseases, particularly in this modern era. Rasayana's recognition as a nutraceutical, anti-oxidant, and immunomodulator is based on scientific evidence. Rasayana, on the whole, is beneficial to one's physical and mental health. (5-6).
