A
tampon is a mass of absorbent material, primarily used as a feminine hygiene product. Historically, the word "tampon" originated from the medieval
French word "
tampion", meaning a piece of cloth to stop a hole, a
stamp,
plug, or
stopper. At present, tampons are designed to be easily inserted into the
vagina during
menstruation and absorb the menstrual flow. Several countries regulate tampons as medical devices. In the United States, they are considered to be a Class II medical device by the
Food and Drug Administration (FDA). They are sometimes used for
hemostasis in
surgery.
