Pleurisy root promotes tremendous heat in thebody, which helps raise the body temperature and encourage perspiration. At the same time, pleurisy root is charging through the body, opening up the lung capillaries and working to thin mucus and congestion, which makes it easier to expectorate. Because it increases circulation in the lungs, it quickly begins to ease chest tightness which, in turn, helps to reduce discomfort.
