The immune system is the body's natural defense system. However, at times challenges to the immune system may call for some extra nutritional support. Andrographis paniculata, a common name in Ayurveda medicine is one such immune enhancing herb that confers immunomodulating properties that help stimulate the immune system (Okhuarobo eta l.,2014).
The plants active component, andrographolide is a potent immune system stimulant that works by enhancing cell-mediated immune response. For instance, research shows that natural killer cell mediated target cell lysis is enhanced by the administration of andrographis paniculata extract. Besides, andrographolides promote the production of white blood cells, interferon release and enhance the protective function of the lymphatic system. The macrophages and antibodies produced scavenge for invaders through antibody dependent cell-mediated cytoxicity thus restoring immunity (S. (2013, August 01). They also, reduce the levels of pro-inflammatory cytokines such as IL-1beta, IL-6, GM-CSF and TNF-alpha (Sheeja & Kuttan, 2010). Therefore, it is evident that Andrographis paniculata's immune stimulating ability confer its beneficial biological properties.
