The present invention relates to a composition for preventing or treating respiratory diseases, and more particularly, to a pharmaceutical composition, and to a
health food, comprising extracts of herbal mixtures or fermented products thereof having
lactic acid bacteria as effective ingredients for preventing or treating respiratory diseases, wherein the herbal mixtures comprise:
Sophora flavascens, Radix glycyrrhizae,

basophil leukocytes to levels similar to that of a
normal group; and reducing the infiltration of inflammatory cells and eosinocyte cells near AHR on
lung tissues. Therefore, the
herbal extracts or fermented products thereof having
