The invention relates to a spraying medicament used for treating snore, which is prepared by the following steps: firstly, adopting the following raw materials proportioning by weight according to the components in the preparation method: dimethyl sulfone, glycerol, peppermint oil, ethanol, stevioside and purified water, wherein each 100g of spraying medicament comprises the following components: 3-5g of dimethyl sulfone, 8-12ml of glycerol, 10-12ml of peppermint oil, 20-24ml of ethanol, 15-18g of stevioside and the balance purified water, then putting the six components into a high-speed mixer and mixing evenly; and finally, pumping into an ozone sterilizer by a miniature beverage pump, sterilizing and filling. The spraying medicament for treating snore, which is prepared by the method, is colorless transparent liquid, has no toxic or side effect, regulates the variation activity of the relevant cells of the tissue of the respiratory tract by rectifying the abnormal secretion of the in-vivo glandular organ, enables the abnormal exudate of the cells of the trachea wall, the soft-palate tongue root tissue and the nasal cavity to get right, retracts the local tissue structure to become healthy and tough, dredges the respiratory tract, enables the respiratory tract to be smooth, enables the airflow to be unhindered and acts as the effect of eliminating or lightening the snore. Functional experiments prove that the invention has the function of preventing the snore. By clinical verification, a patient does not have a discomfortable feeling, and the invention has good adaptability and no side effect.
