providing an open cell foam layer having a width to fit within the perineal area and a thickness of about 1 millimeter to about 30 millimeters such that the open cell foam layer is flexible and can conform to the perineal area of the woman when hydrated and frozen;
applying a substance having a viscosity of at least 400 centipoise to be integrated with the open cell foam layer which provides a gel like consistency and allows passive diffusion of the substance through the open cell foam layer to give a uniform saturation, the substance comprising witch hazel, aloe vera, and water, and allowing the substance to permeate partway into the open cell foam layer; and
sealing the open cell foam layer inside a sealed package to allow the substance to further permeate into the open cell foam layer within the sealed package over time.
