Abstract
The present study is carried out to evaluate the immuno-modulatory activity of Vacha Dhatryadi Avaleha in albino rats. Vacha Dhatryadi Avaleha was prepared by classical method and evaluated for humoral antibody formation and cell-medicated immunity in established experimental models. Test formulation was administered at the dose of 900 mg/kg and parameters like hemagglutination titer, ponderal changes, histopathology of immunological organs and immunological paw edema were recorded. Vacha Dhatryadi Avaleha significantly enhanced antibody formation and moderately suppressed the immunological edema. The present study concludes that Vachadhatryadi Avaleha has immunopotentiating activity.
