According to Ayurveda human body is constituted of seven dhatu (tissues). Which is rasa, rakta, mamsa, meda, asthi, majja and shukra. These dhatu are formed after digestion of ingested food (Ahara). When all the dhatus are formed, the last essences of these dhatus which form is called as Oja or oja. It is the essence of dhatu, which gives strength (bala) to the body, vigour, vitality, improves immunity power and takes care of well-being of the body. It is present all over the body like ghee exists in the milk or honey exists in the flower. Oja in Ayurveda is considered as the resistance to decay and degeneration of the body and immunity against diseases. Chakrapani has previously described immunity in terms of Vyadhikshamatva. In Ayurveda, Immunity as Vyadhikshamatva is defined as a condition of equilibrium of Oja, Bala, and Prakrit Kapha. The concept of immunology as described in ancient Ayurvedic literature is stated as vyadhikshamatva or ojabala of an individual. The sahaja bala may be clinically correlated as natural immunity whereas kalaja and yuktikrita bala as acquired immunity. Its Ayurvedic concept of Karya-Karna Sidhanta, the Aahara is Karya & Karana is Oja. Increase of Oja bestows Tusti (satisfaction), Pusti (good nourishment) and Baladaya (improvement of strength, physical, mental and capacity to resists disease). Ojas Kshaya on the other hand, weaken the body given to many diseases to develop, shortens life span and even kills the person. The following review article conducts a critical analysis of the ancient texts in order to assess the idea of Oja with regard to its Ayurvedic component and to establish how it relates to the Vyadhikshamatva.
