This branch of Ayurveda deals with diseases and illnesses related to aging, as well as science of longevity and rejuvenation. It deals with preventive healthcare, tips, treatments, herbal medicines (rasayana) to enhance quality of life and lead a healthy, happy life full of vitality and vibrancy. Jara chikitsa (jara meaning degeneration) also deals with degenerative disorders irrespective of one’s age. This Ayurveda branch talks about different types of rasāyanas like Ausadha Rasāyana (drug based), Āhāra Rasāyana (dietary), and Achara Rasāyana (behavioral discipline). Jara Chikitsa includes healing modalities to achieve longevity, better memory, youthfulness, brightness, positive emotions and virtues, strength, immunity and vitality. Rasayana works to improve dosha imbalances, rekindle digestive Agni and restore health with use of diet and herbal medication.
The focus of Ayurveda is not just to mitigate symptoms but it also focuses on keeping illnesses away and rasayana chikitsa or rejuvenation therapy is one way Ayurveda achieves this goal of preventive care.
There are three sub branches of Rasayana Chikita—Naimittika Rasayana (curative rejuvenation), Ajasrika Rasayana (promotion of health and a healthy lifestyle) and Kamya Rasayana (longevity, fertility and memory enhancement).
Naimittika Rasayana is a curative discipline that examines and uses herbal drugs, formulations and their potency to speed up recovery from existing diseases or illnesses.
Ajasrika Rasayana is dedicated to the science of wellness and includes everything from diet, herbs, dairy, exercise and practices to lead a spiritually, mentally and physically optimal life. It details the goodness and benefits of everything that the nature provides for enhancing human health.
Kamya Rasayana is the discipline that deals with the biochemistry of desire (kama), it also talks about the science of prana or life force, memory and intellect and how these can be improved along with increasing lifespan.
According to Ayurveda, all life is made out of the five great elements called the Panchamahabhutas that form the three fundamental bio energies governing multiple life functions. These three bio energies are called Doshas-pitta dosha (fire and water), vata dosha (air and ether) and kapha dosha (earth and water). In an individual usually any one or two of them predominate and form the basis of our unique physio mental constitution called Prakruti. Rasayana therapy aims to address the imbalances in these doshas to restore and rejuvenate our body and mind.
