Women have been menstruating since the dawn of time. Ancient Egyptians fashioned tampons out of papyrus, Roman women turned to wool, and Hawaiian ladies used their native fern plant—but the tampon as we know it is a relatively new luxury.
For instance, did you know that in the mid-20th century, religious leaders feared that using a tampon could lead to arousal? If only they'd bothered to ask any woman who's ever used a tampon—we could have told them there's nothing remotely sexy about using them!
The average woman also uses 16,800 tampons in her lifetime, costing more than $3,000. And while alternative methods, such as menstrual cups, are gaining in popularity, around 70 percent of the female population in the U.S. uses tampons.
