This composition for use in the oral cavity is characterized by containing scutellaria root, cinnamon, and hoelen. When the content of scutellaria root in the composition for use in the oral cavity is taken as XA [mass%] and the content of cinnamon in the composition for use in the oral cavity is taken as XB [mass%}, the relationship 0.00005 ≤ XB/XA ≤ 20,000 is preferably satisfied. When the amount of scutellaria root contained in the composition for use in the oral cavity is taken as XA [mass%] and the amount of hoelen contained in the composition for use in the oral cavity is taken as XC [mass%], the relationship 0.000025 ≤ XC/XA ≤ 40,000 is preferably satisfied. It is thereby possible to obtain a composition for use in the oral cavity, in which a plurality of herbal medicines are blended, and with which a mouth odor-preventing effect is obtained at lower doses than through use of the herbal medicines individually.
