PROBLEM TO BE SOLVED: To provide a method for producing an extract derived from rush having a unique aromatic odor of a fresh, new tatami-mat, to provide such an extract, and to provide a "brain function improvement agent utilizing an olfactory sense" that presents a preventive therapeutic effect for dementia or the like.SOLUTION: A method is for producing an extract having an aromatic odor of a tatami-mat. The method includes, after harvesting, dyeing rush with mud before dehydration, dehydrating the rush, crushing while agitating the dehydrated rush by an agitation blade, heating and decompressing the rush under the crush and agitation, and extracting and producing an extract. An extract is obtained by the method. A brain function improvement agent utilizing an olfactory sense and a neurotransmitter modifier contain the extract. 【課題】新鮮な青畳の独特な芳香を有するイグサ由来の抽出液の製造方法を提供することであり、かかる抽出液を提供することであり、また、認知症等に対して予防治療効果を奏する「嗅覚による脳機能改善剤」を提供すること。【解決手段】畳の香りを有する抽出液の製造方法であって、収穫後乾燥前のイグサを泥染めして乾燥した後に、該一旦乾燥がなされたイグサを、撹拌羽根で破砕しながら撹拌し、該破砕・撹拌下に外部から熱を加えつつ減圧して抽出する工程を有する抽出液の製造方法、該製造方法で得られた抽出液、該抽出液を含有する嗅覚による脳機能改善剤、及び、脳神経伝達物質調整剤。【選択図】図１
