The invention belongs to the technical field of biological medicine preparation, and particularly relates to a composition for relieving oral ulcers and a preparation method and application thereof. Including active polysaccharide, natural extract and natural polyphenol compound, the mass percentage of the active polysaccharide, natural extract and natural polyphenol compound is 1.1-2:0.03-3:0.003-0.3. The present invention selects active polysaccharides, natural extracts and natural compounds as raw materials to prepare a composition through screening and analysis, which can inhibit phenol-induced decrease in the activity of human immortalized oral epithelial cells (HIOEC), inhibit the secretion of inflammatory cytokines, and reduce oral ulcers area, reduce local pathological changes, reduce the degree of edema of oral ulcers, and can also be used to prevent dental caries and relieve periodontitis. |
