The legendary Rasayana Chikitsa, or Rejuvenation Therapy, is often considered synonymous with rebirth, for it completely revitalizes the body, eliminating the ill-effects of all previous disorders. Its cleansing effect gives a second lease of life by completely decontaminating the body, mind, and spirit.
Rasayana is derived from two separate Sanskrit words: Rasa meaning the "basic essence that nourishes the body," and Ayana meaning "path". Hence, Rasayana stands for a nourishing pathway. Rasayana Chikitsa is a holistic revitalization therapy aimed at treating nutrient deficiencies, with a focus on the constituent elements of the body.
