[0033] The object of the present invention is to provide a health food and its preparation method with the effect of preventing and improving chronic enteritis and the gastrointestinal discomfort caused by it. Whether discomfort has preventive and ameliorating effects. In order to achieve the above object, the technical scheme adopted in the present invention is to establish the rat chronic enteritis induced by TNBS (trinitrobenzene sulfonic acid) and the gastrointestinal discomfort model thereof, so as to determine and evaluate the effect of polysaccharide combination on chronic enteritis and the effect thereof. The prevention and improvement of gastrointestinal discomfort. The specific process steps are as follows:
[0034]First, 84 SPF SD rats were divided into four groups, namely blank control group, model control group, positive drug control group, Codonopsis polysaccharide group, Poria polysaccharide group, Hericium erinaceus polysaccharide group, Codonopsis polysacchar...
