Catholics and catholiphiles are well-acquainted with the rite of Holy Communion (aka the sacrament of the Eucharist), where you partake of the 'body and blood of Christ' in the form of bread (usually Eucharist wafers) and wine that have been consecrated by the priest. The process by which the bread and wine become body and blood of Christ is known as transubstantiation. The purpose of this sacrament is to nourish the soul and spirit with the true Flesh and Blood, Soul and Divinity of Jesus.
In Canada, the Listerine company (a division of Pfizer-Warner-Lambert Consumer Group) manufactures a product called PocketPak Oral Care Strips under the Listerine brand. The product is not available in the United States. The product resembles a piece of very thin vinyl or acetate, shiny on one side and matte on the other, transluscent and tinted a bluish-green. They are rectangular and are slightly smaller than a communion wafer. You use them by placing them on your tongue and letting them dissolve. They freshen your breath much faster than mints or gum and they do not require water. Plus, they come in a cute little plastic dispenser.
When BenCA, Darnoc, and zumthing visited me in Toronto in April 2001, Darnoc immediately took a liking to the PocketPaks and dubbed them "Breath of Christ" for their resemblance to taking communion.
