Ayurveda the age-old science of life has contributed as a major system in maintain and fulfilling the health-related needs of human society. This science has witnessed drastic changes in environments, lifestyle and so on. This had been possible because of strong, universal, unchanged principles of Ayurveda. The epitome of Ayurveda science and utility is firmly standing on fundamental principles of Ayurveda Ojas literally means “vigor”. The Ojas is one of the tools for the achievement of this aim. Acharaya Sushruta describes Ojas as the Paramateja of the Saptadhatus and as the Bala or biological strength of an individual. Ojas act as resistance to Roga which prevents abnormalities in body and acts as protection against various antigens & foreign bodies. It is the quite essential for our life, energy and exists on a subtle level in the body. Disease strikes at the location where there is derangement of Ojas. The diseases such as AIDS, Diabetes, Pandu, Rajaykshma, Ghrahani etc, can manifest features of decreasing immunity or rather Ojakshaya. Vyaadhiksamatva, literally means "resistance (Ksamatva) against disease (Vyadhi).

Ayurveda also mentioned a number of methods to encourage Ojas & Vyadhikshamtva. Factors which contribute for Vyadhikashamatva are normal Dosa, equilibrium state of Dhatu, normal Agni, and patency of Srotasa etc. Protection of health and maintenance of Arogyata is the main aim of Ayurveda. The Physical and mental resistance to disease is of enormous significance to all living beings; it regulates both, prevention against and rapid recovery from diseases. Ojas is located in Haridya (heart) & infiltrates all over the body.
