In her book Everything You Must Know About Tampons (1981), Nancy Friedman writes, "[T]here is evidence of tampon use throughout history in a multitude of cultures. The oldest printed medical document, Papyrus Ebers, refers to the use of soft papyrus tampons by Egyptian women in the fifteenth century B.C. Roman women used wool tampons. Women in ancient Japan fashioned tampons out of paper, held them in place with a bandage, and changed them 10 to 12 times a day.
