The tampon insertion device according to the present invention includes a barrel having an insertion end portion and a proximal end portion opposite the insertion end portion and having a continuous side wall extending therebetween that defines an interior area. A tampon is initially positioned in the interior area of the barrel. The tampon insertion device includes a plunger slidably coupled to the barrel that has a first end engaging a proximal end of the tampon, the plunger having a cylindrical configuration selectively slidable from a starter configuration extending away from the proximal end portion of the barrel to a deployed configuration positioned downstream inside the interior area of the barrel. Pressure applied to the plunger causes the plunger to urge the tampon downstream within the interior area of the barrel. The tampon insertion device, i.e. the tampon applicator, is constructed using a material consisting essentially of hemp plastic.
