In the fifth century A.D, the tampons were created by Egyptian women from softened papyrus. In the year 1931, the first modern disposable tampons were created by an American, Dr. Earle Haas. The tampon is inserted into a wound or body cavity to absorb blood. It is made from a bulk of rayon or cotton or a mixture of the two.
Haas wanted to invent something better than the rags his wife and other women had to wear, he said, and got the idea for his tampon from a friend in California who used a sponge in the vagina to absorb menstrual flow. So he developed a plug of cotton inserted by means of two cardboard tubes; he did not want the woman to have to touch the cotton.
