PREPARATION AND FUNCTIONAL FOOD CONTAINING MINUS ION-GENERATING MATERIAL FORMED INTO ULTRAFINE POWDER OR FAR-INFRARED RAY-GENERATING MATERIAL AS ACTIVE INGREDIENT
PROBLEM TO BE SOLVED: To provide a preparation and a functional food each containing a minus ion-generating material or a far-infrared rays-generating material capable of sufficiently exhibiting hormesis effect of a minus ion and diathermic effect of far-infrared rays as a main component and having various pharmacological activities. SOLUTION: An agent for preventing and/or improving lowering of an immunological function comprises a minus ion-generating material and/or a far-infrared rays-generating material formed into ultrafine powder until average particle diameter becomes a nano meter (10-9m) order as the main component. An inflammatory wound-injured skin structure-regenerating function-improving promoter, a metabolism function-improving enhancer, an atopic or allergic dermatitis-improving promoter, an ulcerative skin disease-improving promoter, an agent for preventing and/or improving lowering of immunological function or hair growth promoter each comprise the minus ion-generating material and/or the far-infrared rays-generating material formed into ultrafine powder until average particle diameter becomes the nano meter (10-9m) order and one or more kinds of substances selected from sesame fat and a main ingredient fraction of sesame fat, shea butter and sugar ceramide.
