PROBLEM TO BE SOLVED: To provide an agent effective for suppressing the generation of active oxygen and preventing the diseases caused by active oxygen based on the new concept that an extracted tea component acts on the generation system of active oxygen and suppresses the generation of active oxygen from its origin. SOLUTION: This agent for suppressing the generation of active oxygen and preventing diseases caused by active oxygen is produced by using a warm water or hot water extract of tea as an active component. The extract is especially tea catechin, i.e., catechins extracted from tea, above all one or more compounds selected from epicatechin, epigallocatechin, epicatechin gallate and epigallocatechin gallate. Active oxygen is e.g. superoxide anion (O2 <-> ), hydroxy radical (.OH), hydrogen peroxide, etc., generated in the body and the diseases caused by active oxygen are periodontosis, pneumonia, aging, cancer, etc., caused by active oxygen. |
