Good defense or immunity is of paramount importance in fighting against microbial infections. Poor immunity, in general, has a huge negative impact on the productivity in school, at work and even within the family. Retaining good immune health is the number one way to prevent illness. Extrammune is a natural immunity enhancer. It helps to stimulate the production and activity of infection-fighting cells, whereby improves host resistance and helps in faster recovery. Haldi (Curcuma longa), Guduchi (Tinospora cordifolia), Tulsi (Ocimum sanctum) and Yastimadhu (Glycyrrhiza glabra) improves the immunity by supporting functions of immune cells. Musta (Cyperus rotundus) is an antipyretic and has antiinflammatory property. Pippali (Piper longum) is immunomodulator, bioavailability enhancer, respiratory tonic, enhances host resistance and helps in recovery from intestinal infections. Ativisha (Aconitum heterophyllum) is immunomodulator, antiinflammatory and stimulates phagocytic activity. Karkatshrungi (Pistacia integerrima) is a respiratory tonic and has antimicrobial activity.
