Introduction: A vast and intricate colony of commensal bacteria lives in the mammalian GI tract. Over millennia, this gut microbiota has co-evolved with its host and benefits it in a variety of ways, including but not limited to digestion, nutrition synthesis, detoxification, protection from infections, and immune system control. Numerous methods have been utilised to show that signals from the gut microbiota are essential for the immune system's development. Concept of Swarnaprashana in Ayurveda and its role in immunity can be understand on the basis of theory of effect of gut microbiota on immunity as honey in the Swarnaprashana acts as a source of various micro-organism as it formed as a result of mixture of nectars from various flowers. This honey and clarified butter containing Swarnaprashana acts as a source which maintains microbiota which upon stimulation triggers the immune response at subclinical level without causing any kind of infection and improving the response for the second time infection and also increase the number of immunoglobulins in the immune system.
