Abstract: Immunomodulatory treatment is usually needed under the conditions of impaired immune responsiveness and when the defense mechanisms of host have to be activated. Though conventional immunomodulatory chemotherapy is available it costs a huge expense and is not usually affordable to ordinary people with low socio economic status. Therefore the modulation of immune system by traditional medicinal plant products has become a subject matter for current scientific investigations worldwide. A wide number of medicinal plants have been indicated in Siddha classical literature towards the management of several diseases that results in immune deficiency. Hence the present literature analysis was performed to have a scientific perspective on some of the selected traditional herbs with immunomodulatory action.
