RASAYANA CHIKITSA AND ITS ROLE IN PROMOTING HEALTH: AN EXTENSIVE REVIEW
Ayurveda, regarded as the world’s oldest system of medicine, encompasses all dimensions of human life. Its fundamental objectives are the preservation of health and the treatment of disease, both of which are effectively supported through Rasāyana Chikitsā (rejuvenation therapy). Rasāyana is specifically aimed at promoting longevity, enhancing memory and intellect, preserving youthfulness, preventing diseases, and improving physical appearance, voice, strength, sensory functions, wisdom, communication ability, and overall vitality. As one of the principal branches of Aṣṭāṅga Ayurveda, Rasāyana focuses on revitalisation and holistic well-being. The formulations and regimens under this therapy act by improving the quality of Rasa Dhātu (nutrient plasma) and other Dhātus (tissues), thereby reinforcing the entire body system. In doing so, Rasāyana enhances immunity, maintains the efficient functioning of vital organs, delays premature ageing, and harmonises the natural processes of growth and degeneration that occur throughout life. Since ageing is characterised by gradual structural and functional decline, Rasāyana therapy plays a pivotal role in slowing these changes. In addition to medicinal preparations, Ayurveda also emphasises Āchāra Rasāyana, a non pharmacological approach that rejuvenates life through proper diet, healthy lifestyle, ethical conduct, and disciplined behaviour. Thus, Rasāyana is not confined merely to herbal remedies but represents a comprehensive system for sustaining health, vitality, and longevity. KEYWORDS: Rasayan, Achar Rasayan, health
