For prevention of diseases, Ayurveda had advocated the adherence to concepts like dina charya, ritu charya, sadvritta , Na vega dharan  etc.  these measures are useful in preventing the lifestyle related diseases but for preventing the Aupsargik rogas (communicable diseases), Janapada dhwansa rogas (epidemic diseases), Krumij Roga (Infectious diseases), Asatmyaj roga (allergic disorders), the concept of Vyadhikshamtva (Immunity) is propagated by the Ayurvedic science [1]. According to the concept of Ojas or Vyadhikshamatva or Bala (immunity), the body‟s resistance is of tremendous importance in the daily welfare of living beings not only for disease prevention but also for rapid recovery after disease affliction. [2] Ayurveda propounds that prevention is an equally important aspect of disease management as cure and thus, strengthening the immune system, is a natural way to help the body fight against the disease-causing pathogens. Acharyas promoted the use of Rasayana (Rejuvenation) to enhance ojas and vyadhikshamatva (immunity). This article is an effort to present Ayurvedic concepts of Vyadhishamatva.
