The DivaCup is a healthier, cheaper and greener alternative to using tampons and pads for menstruation. It is made of medical grade silicone and is reusable, you just rinse it and re-insert into the vaginal canal. It comes in two sizes; one often fits a woman prior to childbirth, the larger size after having children. The video below explains the toxic waste associated with pads and tampons. It also shows which chemicals are found in commercial brand tampons, that often leave fibers in your vagina that could in all likelihood contribute to cancer, due to the sheer volume of tampons inserted in the vagina over a lifetime of fertility.
