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.Ce rince-bouche contient de la racine de scutellaria, de la cannelle et de l'hoelèn. Lorsque la teneur en racine de scutellaria est prise comme X A [% de masse] et que la teneur en cannelle est prise comme X B [% de masse}, la relation 0,00005 ≤ X B/XA ≤ 20 000 est satisfaite. Lorsque la quantité de racine de scutellaria est prise comme X A [% de masse] et la quantité de hoelène est prise comme X C [% de masse], la relation 0,000025 ≤ XC/XA ≤ 40 000 est satisfaite. Il est ainsi possible d'obtenir un mélange de plusieurs plantes médicinales, pour empêcher les odeurs de bouche, à des concentrations inférieures à celles de leur utilisation individuelle.本発明の口腔用組成物は、オウゴン、ケイヒおよびブクリョウを含有することを特徴とする。口腔用組成物中における前記オウゴンの含有率をＸＡ［質量％］、口腔用組成物中における前記ケイヒの含有率をＸＢ［質量％］としたとき、０．００００５≦ＸＢ／ＸＡ≦２００００の関係を満足することが好ましい。口腔用組成物中における前記オウゴンの含有率をＸＡ［質量％］、口腔用組成物中における前記ブクリョウの含有率をＸＣ［質量％］としたとき、０．００００２５≦ＸＣ／ＸＡ≦４００００の関係を満足することが好ましい。これにより、複数の生薬が配合され、単独の生薬を用いるよりも低薬量で効果が得られる口臭予防効果を有する口腔用組成物を得ることができる。
