The invention discloses a method for extracting an additive from geotrichum candidum fermented burdock by using alcohol and application of the additive, belonging to the technical field of cigarette spice extraction. In the method, geotrichum candidum with the capacity of efficiently degrading grease is adopted to ferment the burdock, and then the alcohol is utilized to extract the burdock to obtain an alcohol extract. The invention also provides the application of the alcohol extract from the burdock extracted by using the alcohol to the cigarette additive. The method for extracting can effectively degrade the grease component which is not beneficial to cigarette sense organs and generate micromolecular acid components which are beneficial to the cigarette sense organs; the obtained additive contains a large number of fragrant substances required by tobacco and a few substances influencing the tobacco smoking taste and quality.
