The present invention relates to a new application of Fructus schisandrae total polysaccharides in preparation of medicine or nutraceuticals for treating coughing, and more specifically to a new application of Fructus schisandrae total polysaccharides in preparation of medicine or nutraceuticals for preventing and relieving coughing and eliminating airway inflammation. Experiments demonstrate that the Fructus schisandrae total polysaccharides can remarkably reduce the coughing times of a guinea pig with increased cough sensitivity induced by cigarette smoke and an acute cough guinea pig induced by citric acid smoke, prolong the latent period of cough, and significantly reduce the airway inflammation of the guinea pig with increased cough susceptibility induced by cigarette smoke, so that the Fructus schisandrae total polysaccharides can be used for preparing drugs for preventing cough, relieving cough and eliminating airway inflammation.
