This study aimed to clarify the impact of reusable cloth menstrual pads on the unidentified complaints of female students. We requested 32 nonuser, female students to use cloth menstrual pads for six months between January and July 2007, and investigated every other month with the use of a scale the changes in their unidentified complaints, image of menstruation, self-esteem, and acceptance of sexuality. And we requested them record every menstruation, and interviewed after the intervention. The analysis method used the multiple regression analysis and the t-test. Our survey found improvement in following items; perception of menstruation after two months, reducing of menstrual pain after four months, and improvement of unidentified complaints, self-esteem, and acceptance of sexuality after six months. Detailed analysis of their perceptional changes on menstruation and the interview results discovered that the touch feeling and texture of the cloth pads and the observation of menstrual blood at washing helped to change their perception of menstruation from "bothersome" into "natural", which led to improvement of unidentified complaints. Moreover, our survey found women whom the cloth pads acted on effectively were stronger experience perimenstrual pain, negative emotions, and behavior changes.
